Answer:
From the sunlight (together with CO2 and water)
Explanation:
Photosynthesis is a process performed by the plants (also some algae and bacteria) in which the energy of sunlight is transformed into chemical energy usable by those plants. Necessary components of this set of reactions are sunlight, water and CO2, while resulting products are glucose and oxygen. Products of photosynthesis are then used in the metabolic processes known as cellular respiration. During the cellular respiration, glucose and oxygen are used for the production of ATP, CO2 and water. Cellular respiration is performed in all living organisms.
Photosynthesis occur in the chloroplast, membrane organelles with photosynthetic pigments (such as chlorophyll).
The energy for photosynthesis comes from the sun. Plant-based organisms capture this energy and convert it into a form that is usable by all life through a process known as photosynthesis. This process underpins much of the energy transformation that supports life.
Explanation:The energy for photosynthesis comes from the sun. In this process, green plants, algae, cyanobacteria, and photosynthetic protists capture solar energy and convert this into chemical energy necessary for life - a process known as photosynthesis. This process transforms the radiant energy in sunlight into stored chemical energy.
Part of this process involves using light energy from the sun to transform carbon dioxide and water into glucose and oxygen. Other organisms consume these glucose-bearing plants and use the glucose to create ATP, a molecule used for energy storage in cells.
Overall, it's the energy from the sun that is harnessed through the process of photosynthesis that provides most of the energy required by living organisms on earth. Without the solar energy captured during photosynthesis, life as we know it would not exist.

Explanation:
Beyond their role in energy transfer, what other benefit do microorganisms that act as producers provide for ecosystems
Microorganisms that act as producers in ecosystems contribute to nutrient cycling, form symbiotic relationships with plants, participate in bioremediation, and are integral to soil formation and stabilization.
Explanation:Beyond their role in energy transfer, microorganisms that act as producers provide a myriad of benefits for ecosystems. Microorganisms such as bacteria and fungi play crucial roles in nutrient cycling, including the carbon and nitrogen cycles. These cycles are essential for maintaining the balance of nutrients, such as carbon and nitrogen, in ecosystems.
Many microorganisms form symbiotic relationships with plants, such as nitrogen-fixing bacteria that associate with the roots of legumes, thereby enriching the soil with nitrogen that plants can use. Furthermore, microorganisms contribute to soil formation and stabilization, which prevents erosion and maintains soil health. This in turn supports plant growth and promotes biodiversity.
Microorganisms also engage in bioremediation, a process where they remove pollutants from the environment. This is vital for maintaining clean air and water. In addition, their decomposing action is necessary for the breakdown of organic matter, which replenishes nutrients in the ecosystems. These functions are indispensable for the survival not only of individual ecosystems but also of the planet as a whole.

In Europe, three lineages of bears evolved from a common ancestor. Two of those lineages led to present-day black bears and brown bears. The third lineage led to cave bears that went extinct 24,000 years ago. Which of the following could explain why only one group of bears went extinct? A. Individual cave bears must not have been able to adapt to changing conditions as quickly as brown or black bears. B. One group of bears was less highly evolved than the other two groups and was destined to die out. C. Some environmental change severely threatened cave bear survival but not the survival of brown or black bears. D. Random chance led to the extinction of cave bears and survival of brown and black bears.
Answer: A Individual cave bears must not have been able to adapt to changing conditions as quickly as brown or black bears.
Explanation:
If an any living thing can not adapt to its surroundings, then the species will go extinct as it will no longer be able to survive in those surroundings. Brown and black bears were able to adapt to the changing conditions and thus survived until today.
Final answer:
The extinction of cave bears, in contrast to the survival of black and brown bears, is most plausibly explained by environmental changes that severely threatened cave bear survival. Factors such as adaptation capabilities, dietary flexibility, and impact of human expansion play significant roles in the survival or extinction of species.
Explanation:
The question asks why only one group of bears went extinct, given that three lineages evolved from a common ancestor in Europe, leading to present-day black bears, brown bears, and the now-extinct cave bears. There are several explanations for the extinction of only one group, but the most plausible reason is related to environmental changes and adaptation. Specifically, Option C: Some environmental change severely threatened cave bear survival but not the survival of brown or black bears, is a compelling explanation. This is supported by historical evidence indicating that environmental changes have played a significant role in the extinction of species, including large mammals, during periods of climate change and human expansion. The ability of species to adapt to changing environments, dietary flexibility, and geographical spread also significantly impact their survival. Unlike their relatives, cave bears may have had more specialized needs or were unable to adapt as effectively to changing conditions, leading to their extinction approximately 24,000 years ago.
The process of making rna from dna is called
Answer: DNA transcription
Transcription is the process where RNA is created from DNA using RNA Polymerase. This creates an mRNA strand carrying genetic instructions which will be translated into a protein during translation.
Explanation:The process of creating RNA from DNA is known as transcription. This process involves an enzyme known as RNA Polymerase which unzips the DNA's double helix structure to use one strand as a template for building an mRNA molecule. The constructed mRNA molecule carries genetic instructions from the DNA and these instructions will subsequently be read by ribosomes in the protein synthesis process, also known as translation.
Transcription can be divided into three main stages: initiation, elongation, and termination. During initiation, the RNA Polymerase attaches to a specific area on the DNA strand. For elongation, the enzyme moves along the DNA template, synthesizing a new mRNA strand in a 5' to 3' direction. Once the RNA Polymerase encounters a termination signal on the DNA, transcription stops, and the mRNA molecule is released.

I believe that they’re norepinephrine (NE), and the acetylcholine (Ach). Hope this helps!
The autonomic nervous system uses two key neurotransmitters, acetylcholine (ACh) and norepinephrine. They are released by the fibers of the sympathetic and parasympathetic divisions, binding to specified receptors on the target cells.
Explanation:The two main neurotransmitters of the autonomic nervous system are acetylcholine (ACh) and norepinephrine. Sympathetic and parasympathetic divisions of the autonomic nervous system have both types of neurons. The pre-ganglionic fibers release ACh and these fibers have nicotinic receptors in their cell membranes. Postganglionic parasympathetic fibers also release ACh, but the receptors on their targets are muscarinic receptors. On the other hand, postganglionic sympathetic fibers release norepinephrine, which binds to adrenergic receptors on the target cell. The exception is the fibers that lead to sweat glands and blood vessels associated with skeletal muscles, which release ACh.

Explanation:
Peripheral nervous system consists of all the neurons and ganglia within the body, outside the central nervous system. It is divided into:
Somatic nervous system- it controls the movements of skeletal muscles which means that this nervous system is under the voluntary controlAutonomic nervous system- its role is to control involuntary movements of smooth muscles and glandsAutonomic nervous system consists of:

The vagus nerve primarily serves the parasympathetic division.
Explanation:The description that is NOT consistent with the sympathetic division is 'most innervation from the vagus nerve'. The sympathetic division of the autonomic nervous system (ANS) is characterized by its thoracolumbar division and its ganglia being close to the spinal cord. It also features long postganglionic fibers. However, the vagus nerve primarily serves the parasympathetic division of the ANS, not the sympathetic division.

The Punnett square illustrates a cross for flower position in the pea plant. The phenotypes and genotypes of the parents have been given. The allele for axial position is dominant and represented by A. The allele for terminal flower position is recessive and represented by a. What is the genotype of the offspring? Heterozygous homozygous recessive homozygous dominant
Final answer:
The genotype of the offspring from a cross involving homozygous dominant (AA) and homozygous recessive (aa) parents will all be heterozygous (Aa) for the F1 generation with an axial flower position phenotype. In an F2 cross (Aa x Aa), the genotypic ratio will be 1 homozygous dominant (AA), 2 heterozygous (Aa), and 1 homozygous recessive (aa), with a phenotypic ratio of 3 axial to 1 terminal.
Explanation:
The gene for flower position in pea plants has two alleles: axial (A), which is dominant, and terminal (a), which is recessive. For a cross involving two parents that are homozygous for each trait (AA x aa), all F₁ offspring would be heterozygous (Aa) because each parent can only contribute one type of allele. Consequently, all F₁ plants would display the axial flower position phenotype since it is dominant.
For the F₂ generation, which involves crossing two F₁ heterozygous individuals (Aa x Aa), the Punnett square predicts that the offspring will have the following genotypes and phenotypes: 1 AA (homozygous dominant), 2 Aa (heterozygous), and 1 aa (homozygous recessive). The expected phenotypic ratio would be 3 axial: 1 terminal flowering positions, as the dominant A allele expresses the axial phenotype in both AA and Aa genotypes, while only the aa genotype will express the terminal flowering position.

The term mass wasting describes
the downslope movement of a landslide.
the process by which an area becomes a desert.
islands sinking into the ocean.
glacial movement of boulders.
Answer:
The down-slope movement of Earth's materials due to gravity.
Explanation:
Final answer:
Mass wasting refers to the downslope movement of earth materials driven by gravity and includes landslides, rock falls, slides, and flows, typically caused by factors that destabilize the slope.
Explanation:
The term mass wasting describes the downslope movement of rock and soil material due to gravity. It encompasses a range of movements including landslides, rock falls, rock topples, rock slides, and flows. Mass wasting can be triggered by seismic activity, volcanic eruptions, intense rainfall, and human activities that weaken slope stability. Key factors that influence mass wasting are the slope's angle and the shear strength of the slope materials.
When the shearing stress on earth materials exceeds their shearing strength, mass movement occurs. Landslide is a term often used synonymously with mass wasting, though it typically refers specifically to the rapid movements within this category. Therefore, out of the given options, mass wasting describes the downslope movement of a landslide.

Xavier boiled 45 grams of water. If all of the water changed into a gas, what would be the weight of the water vapor?
Answer:
45 g
Explanation:
Conservation of matter.
Final answer:
Xavier boiled 45 grams of water and the weight of the resulting water vapor will also be 45 grams, as the mass remains constant when water changes state due to the Law of Conservation of Mass.
Explanation:
If Xavier boiled 45 grams of water and all of it changed into a gas (water vapor), the weight of the water vapor would still be 45 grams. This is because the Law of Conservation of Mass states that mass is neither created nor destroyed in a chemical reaction. When water boils and changes from a liquid to a gas, the substance is still water (H₂O), and thus the mass remains the same, just in a different state of matter.
PLEASE HELP!!!! I WILL GIVE BRAINIEST!!!! What is the difference between weathering and erosion? How are mechanical weathering and chemical weathering different? How are hydrolysis and oxidation similar? Explain the process of exfoliation. As waves crash into rock along the shoreline, particles of sand, shell, and other materials in the ocean water loosen tiny bits of sediment from the rock. As the waves recede, they carry the sediment away. In this scenario, which process represents weathering, and which process represents erosion?
Answer:
Explanation:
1. What is the difference between weathering and erosion?
ANSWER
Weathering is the physical disintegration and chemical decomposition of rocks to form soils and rocks. Weathering acts to break down earth materials.
while
Erosion is the wearing or washing away of weathered materials. Without weathering, there won't be erosion.
2. How are mechanical weathering and chemical weathering different?
Solution
Mechanical weathering is the physical disintegration of rocks. Examples are:
>Pressure release on rocks
>Biological activities
>Freezing and thawing
> Drying and wetting of rocks
Mechanical weathering helps to loosen rocks and to increase surface area of exposure of rocks.
while
Chemical weathering is the deacy and decompostion of rocks. Chemical reactions on rocks are initiated naturally in different forms. Bonds between rock molecules are broken, water can dissolve some soluble rock contents, etc, all this would lead to chemical weathering of such rocks. Chemical weathering occurs through:
>Hydrolysis
>Carbonation
>Oxidation etc.
4. How are hydrolysis and oxidation similar?
Hydrolysis and oxidation are both processes of chemical weathering. They aid in chemical decomposition of rocks.
Hydrolysis causes decompositon through the action of water. In oxidation, oxygen reacts with earth materials.
5. Explain the process of exfoliation.
Exfoliation is a physical weathering process. It accompanies pressure release on a rock surface.
Rocks overly one another and by so doing, they mount pressure on the underlying ones. The part of the bedrock close to overhead rock receives more pressure while the part far away receives little to no pressure. This differential pressure is what leads to exfoliation of rocks. Exfoliation is produced when the overlying rock is moved away and the pressure is released.
When a rock exfoliates, it breaks down into layers like an onion skin. It can create a massive feature known as an exfoliation dome. Each sheet is a product of pressure differences.
6. As waves crash into rock along the shoreline, particles of sand, shell, and other materials in the ocean water loosen tiny bits of sediment from the rock.
>>>>>>>>>This is weathering
As the waves recede, they carry the sediment away. In this scenario, which process represents weathering, and which process represents erosion?
>>>>>>>>> This is erosion
Answer:
1.Weathering is the breakdown of rock into smaller particles through mechanical or chemical means. Erosion is the process by which weathering products are carried away.
2.Mechanical weathering simply breaks rock into smaller fragments. Chemical weathering actually changes the mineral composition of rock.
3.Hydrolysis and oxidation are similar in that both involve chemical reactions between a mineral and another material. Hydrolysis is a chemical reaction between a mineral and water. Oxidation is a chemical reaction between a mineral and oxygen.
4.Exfoliation is the cracking of rock caused by a decrease in pressure. It occurs when a mass of rock is exposed by weathering and removal of the overlying rock, which decreases pressure on the rock. As a result, the rock expands, which causes the rock to crack.
5.In the scenario, weathering occurs when tiny bits of sand and shell in the waves loosen bits of sediment from the rock. Erosion occurs when the waves carry away those bits of sediment.

Answer:
C. a decrease in phospholipid fatty acid side chain length and a decrease in side chain saturation
Explanation:
Temperature is a factor that has a huge impact on cell membrane structure, more precisely its fluidity. So, for example, if temperature increases, the cell membrane becomes more fluid because the fatty acid tails of the phospholipids become less rigid.

In this cross-yellow color of pods showing dominant trait over the green color pod, all the progeny shows the yellow color phenotype, hence option D is correct.
What is a dominant trait?According to the law of dominance, dominant traits in alleles mask the feature of the recessive allele.
In the given question yellow color of the pod shows the dominant trait, so it will mask the character of a recessive allele which is shown by green pods.
During the cross in the F1 generation recessive character is not expressed by the allele and after this generation, it will express.
Cross between parents: YY x gg
Gametes: Y and g
Phenotypes: all the progeny will be 100% yellow
Genotypes: Yg, Yg, Yg, Yg
