The inner planets are dense and rocky due to solar heat allowing only heavy materials to condense, while outer planets, formed in the cooler outskirts, accumulated light gases around their rocky cores, leading to their large gaseous makeups. The outer planets also host rings and moons due to their strong gravity.

The inner planets, consisting of Mercury, Venus, Earth, and Mars, are dense and rocky due to the high temperatures in the inner solar system when these planets formed. In such heated environments, lighter materials like water, gas, and ice cannot remain solid and are either incorporated into the planets in small amounts or dissipated into space. As a result, inner planets are composed primarily of heavier materials such as rock and metal, which can resist the solar heat.

On the other hand, the outer planets (Jupiter, Saturn, Uranus, and Neptune) are much larger and consist largely of gases, giving them lower densities with no solid surfaces. They do have solid rocky cores, which formed early in the solar system's history, but are enveloped in thick atmospheres mostly made of hydrogen and helium because, in the colder outskirts of the solar system, these light gases could accumulate around the core. Additionally, the intense pull of gravity from these massive planets helped retain the gaseous atmospheres.

The outer planets also have extensive systems of rings and moons which are linked with these planets' strong gravitational fields, attracting and capturing a multitude of objects over time.

Light energy is used by the flower to bloom that could allow the flower to remove its pollen for the pollination process. Also the light allows the flower or the plants to make food and that is why they bloom if its is portrayed be the light.  

Explanation:

The greater the intensity of light, the more photons or photoelectrons there are and consequently the increase in photocurrent. Thus, the larger the energy, the greater the wattage of the light source.

The correct answer is - d. all of the above.

The fish populations and other aquatic resources can be affected by multiple factors. The water temperature is a defining factor, if it is colder than lots of marine life will dye out and be replaced with other species, and vice versa, if its too warm lots of marine life adapted to colder conditions will die out. Diseases are always an impact factor in any environment, so if a dangerous, fatal, disease appears, it can demolish the populations of the aquatic organisms. The water quality is becoming an ever-growing concern, and that is because of the human activity. If the water gets polluted, or eutrophicized, the marine life will very quickly die out and leave empty waters behind it.

Answer:

D is the anwser

Explanation:

A mutation can affect gene expression, leading to changes in the transcription and translation processes, which can result in hereditary diseases or cancer. Heritable information in eukaryotes is transferred through mitosis, meiosis, and fertilization. Mutations are essential for introducing new genetic variations in populations.

The cellular process that would be affected by a mutation is known as gene expression, which includes transcription and translation of hereditary instructions in DNA into functional proteins. A mutation, being a heritable change in the DNA sequence, can affect the structure and function of proteins, potentially leading to an altered phenotype. If the mutation occurs in a germ cell, it can be passed on to offspring, potentially resulting in hereditary diseases. Conversely, if the mutation occurs in a somatic cell, it can be propagated through cell division in that organism, which can sometimes cause cancer if the mutation is oncogenic.

In eukaryotes, heritable information is passed to the next generation through the cell cycle, including processes of mitosis and meiosis, followed by fertilization. Mutations introduce new genetic variations into a population, which can have various effects. These can range from no visible change to significant alterations in the organism's characteristics, and are crucial for the process of evolution.

A mutation affects cellular processes by changing the DNA sequence that might result in altered protein functions. Mutations in germ cells can lead to hereditary diseases, whereas mutations in somatic cells can cause cancer. The transfer of heritable information in eukaryotes is heavily rooted in processes like mitosis, meiosis, and fertilization which can be influenced by these mutations.

A mutation is a change in the DNA sequence that can affect cellular processes by altering the instructions carried out by a cell. If a mutation occurs in a germ cell, it may be passed to offspring, potentially resulting in hereditary diseases. In contrast, mutations in somatic cells can lead to cancer if they cause cells to become malignant.

In eukaryotic organisms, heritable information is passed down through the cell cycle and processes such as mitosis or meiosis plus fertilization. These processes are vital for the proper transfer of genetic information, and mutations can significantly alter the outcome of these processes.

A mutation can lead to a different phenotype by inducing changes in the DNA, which are then transcribed to mRNA and translated into altered amino acid sequences in proteins. Since proteins perform critical cellular functions, changes in their structure due to mutations can have far-reaching implications for the organism.

Answer: A. In asexual reproduction, offsprings are exact copies...

Explanation: It can’t be B because asexual reproduction only requires 1 parent. It also can’t be C because it’s literally the exact opposite, this is why human children don’t look exactly like their parents. Hope this helped!

Answer:

The second cell would not be able to produce as much food because its not getting as much sunlight.

Explanation:

I just did it

Answer: The correct answer is -

c. the leg.

Skeletal muscle is one of three major categories of muscle tissues (other two being smooth muscle and cardiac muscle.

This is striated muscle tissue, which is voluntary in nature (therefore also termed as voluntary muscle) and lies under the somatic nervous system.

Majority of skeletal muscles are connected to bones with the help of tendons (which are bundles of collagen).

Skeletal muscles provide support to the body and assist in movement. This is because contraction of skeletal muscle allows pulling of tendons, which are basically attached to bone. This assist in movement of legs (such as walking, jumping).

This indicates that every physical activity performed by an organsim is related to skeletal muscle.

Thus, muscles associated with legs are example of skeletal muscles.

Therefore, option c) is the right answer.

The correct answer is option C

The small intestine known as Duodenum is the next organ in the digestive system. Liver comes before the stomach and the large intestine surrounds the small intestine and its function also starts when the di-gested food passes from the small intestine to the large intestine. Kidney is the part of urinary system and not the digestive system.  

Answer:

b

Explanation:

The correct sequence of events in gene expression is DNA to RNA to protein, starting with transcription and followed by translation. In transcription, DNA is transcribed into mRNA, which is then translated into a protein with the help of tRNA. cDNA helps in understanding an organism's proteins by representing only expressed genes.

The correct sequence of events in transcription and translation is DNA to RNA to protein. The process starts with transcription where DNA is converted into mRNA (messenger RNA). This happens in the nucleus of the cell. The mRNA then travels out of the nucleus to the cytoplasm where translation occurs. During translation, the mRNA is read by a ribosome, and tRNA (transfer RNA) brings the appropriate amino acids to create a polypeptide chain, which will fold into a functional protein.

The differences between a sequence of DNA and the sequence of mature mRNA include the removal of introns (non-coding regions) from the pre-mRNA during RNA processing, resulting in only exons (coding regions) being included in the mature mRNA. Additionally, a 5' cap and a poly-A tail are added to the mRNA for stability and regulation of translation.

Complementary DNA (cDNA) created by reverse transcribing mRNA can be particularly useful for understanding an organism's proteins because it represents only the expressed genes and skipping non-coding regions, allowing for a simpler analysis of the coding potential of a genome.

Protista is not valid under evolutionary classification because it's considered a paraphyletic group. In this kingdom, groups have closer common ancestors with groups outside of Protista than within it. This is inconsistent with evolutionary classification, which emphasizes common descent and shared ancestry.

The kingdom Protista is not valid under evolutionary classification primarily because this group is considered to be paraphyletic. A paraphyletic group consists of all the descendants of a common ancestor, excluding one or more groups. For instance, Protista includes various groups that hold the closest common ancestors in kingdoms outside of Protista, rather than within the same kingdom.

This is inconsistent with the principles of evolutionary classification, which emphasizes the concept of common descent. This approach to classification orders organisms based on their evolutionary relationships, meaning that all members of a particular group (whether it's a domain, kingdom, phylum, etc.) should share a most recent common ancestor that is not the ancestor of any organisms outside the group.

So, although some members of Protista are closely related, the kingdom as a whole does not meet these criteria, because it lacks that shared ancestry. Therefore, it is not recognized as a valid group in the current understanding of evolutionary classification.

Answer: animals cell get energy by..

Animals obtain energy by eating plants. The only form of energy a cell can use is a molecule called adenosine triphosphate (ATP). Chemical energy is stored in the bonds that hold the molecule together. ADP can be recycled into ATP when more energy becomes available.

Explanation:

The cells of animals considerably rely on the process of cellular respiration in order to get energy.

Cellular respiration may be defined as a process through which cells of living organisms produce energy with the help of the breakdown of food molecules into simpler substances.

Cellular respiration, also known as aerobic respiration significantly involves the sequence of chemical reactions which initiate with the reactants like sugar (glucose) in the presence of oxygen in order to produce carbon dioxide, water, and energy. Here, the energy that is synthesized must be in the form of ATP.

Cellular respiration is again split into a variety of reactions like glycolysis, the Citric-acid cycle, oxidative phosphorylation, etc. But the ultimate aim of all remains the same which is the production of energy.

Therefore, the cells of animals considerably rely on the process of cellular respiration in order to get energy.

While Jupiter itself does not have volcanoes, its moon Io is the most volcanically active body in the solar system, with eruptions that are hotter and possess a different composition, mainly sulfur, compared to Earth's.

The question 'Does Jupiter have any volcano?' can be answered by discussing one of its moons, Io, which features the most extraordinary volcanic activity in the solar system. Although Jupiter itself does not have volcanoes, Io's volcanism is characterized by high temperatures and eruptions that produce lava curtains and fountains, often of silicate lava similar to Earth's. What makes these eruptions distinct is their composition, consisting largely of sulfur, as well as the formation of massive plumes, such as the bluish one that extends approximately 140 kilometers above the surface and the Prometheus plume that rises about 75 kilometers. These plumes sometimes interact with frozen sulfur and sulfur dioxide, leading to colorful 'snowfalls' of recondensed material that can spread a thousand kilometers from the vent.

Final answer:

In a hypertonic solution, a plant cell becomes plasmolyzed due to water leaving the cell, leading to the plasma membrane shrinking and pulling away from the cell wall.

Explanation:

If placed in a hypertonic solution, a plant cell will become plasmolyzed. In a hypertonic solution, the fluid outside the cell has a higher concentration of solutes compared to the cell's cytoplasm, causing the water to leave the plant cell. Because plant cells have a rigid cell wall, the cell does not burst but instead, the plasma membrane shrinks and pulls away from the cell wall - a process known as plasmolysis. This result is in sharp contrast to a hypotonic environment, where plant cells absorb water, becoming turgid as the central vacuole fills with water and provides rigidity to the cell.

Answer:

When discussing the Earth's magnetic field we could say that the Earth has a GEOMAGNETIC NORTH POLE. The magnetic field changes every several hundred thousand years and thus the north and south magnetic poles swap places. Hope this is the answer that you are looking for.

North Magnetic Pole

Explanation:

    The terrestrial magnetic field is what makes possible the existence of compasses, used for location in space. Thanks to this invention, the great navigations could happen.

    The dynamo theory is the most accepted for the explanation of the terrestrial magnetic field. According to this idea, iron and molten nickel, about 3,000 km deep, move around generating electrical currents that trigger the magnetic field.

Magnetic poles

     A magnet has a north pole and a south pole. The magnetic field generated by the magnets, which is the region near the magnet where another magnet or materials such as iron and steel are attracted, is represented by exiting the north pole and entering the south pole.

    When the magnetized needle of a compass aligns with the earth's magnetic field, the north pole of the needle points to the northern region of the planet and the south pole of the compass magnet points to the southern region of the planet.

    The attraction occurs only between different poles, that is, if the north pole of the needle points to the geographic north, it means that what we call geographic north is the magnetic south pole of the earth. Similarly, the geographic south pole of the planet must be the magnetic north pole. The image above reveals this inversion between the magnetic and geographic poles.

    The earth is a giant magnet, and its magnetic field protects us from particles from the sun.

The correct answer is (a )

This experiment shows that the life has evolved from the inorganic materials. The substances like carbon dioxide, nitrogen gas when heated and exposed to UV radiation led to generation of life supporting element called as amino acids. The UV radiation and heat provided the energy needed by gases to convert into amino acids.
