A purebred y’all plant crossed with a purebred short plant. All F1 offspring are tall. Is the allele for tallness dominant or recessive
dominant because if it wasm't 1 would come out short
Final answer:
The allele for tallness is dominant as it is expressed in the phenotype of all F1 offspring resulting from the cross between a purebred tall plant and a purebred short plant.
Explanation:
If a purebred tall plant is crossed with a purebred short plant and all the F1 offspring are tall, this indicates that the allele for tallness is dominant. This is because the tall characteristic is visible in the presence of both a tall allele and a short allele within the genotype of the offspring. From Mendel's work, we know that when describing genetic crosses, the dominant factor is represented with a capital letter (T for tall) and the recessive factor is represented by a lowercase letter (t for short). In this scenario, the plants with the genotype TT or Tt will be tall, and plants with the genotype tt will be short. Assuming the purebred tall parent had a genotype of TT and the purebred short plant had a genotype of tt, all the F1 offspring would have a genotype of Tt, expressing the tall phenotype because the dominant allele for tallness 'masks' the recessive short allele.

Which best describes the relationship between temperature and dissolved oxygen in a lake?
A.
As temperature increases, dissolved oxygen increases.
B.
As temperature increases, dissolved oxygen decreases.
C.
As temperature decreases, dissolved oxygen decreases.
D.
A change in temperature has no effect on dissolved oxygen.
Answer:
B
Explanation:
Gases slightly dissolve in water and are held loosely by weak inter-molecular forces. When the water gains temperatures, the kinetic energy of the water molecules including those of the gases increase. The dissolved gas molecules are therefore able to overcome the weak forces of attraction in the water and escape through the surface.
Dissolved oxygen levels in a lake usually decrease as the temperature increases. Warmer waters hold less oxygen than cooler waters. For instance, a decrease in dissolved oxygen could happen when lake water heats up during the summer.
Explanation:In a lake ecosystem, there is a relationship between the temperature and levels of dissolved oxygen. Generally, the amount of dissolved oxygen in water decreases as the temperature increases. So, the correct answer would be 'B. As temperature increases, dissolved oxygen decreases.' Warmer waters hold less dissolved oxygen than cooler waters. This occurs because gas solubility is a function of temperature: The warmer the temperature, the less gas there will be dissolved, including oxygen.
For example, when the lake water gets heated up during the summer, dissolved oxygen levels may decrease.

which would BEST allow a species to survive environment changes
The answer you are looking for is genetic diversity
To survive environmental changes, a species' best strategies include having high genetic diversity, the capability for sexual reproduction, and phenotypic plasticity. Proactive conservation efforts are essential to prevent extinction, especially in climate-sensitive species.
The best strategy for a species to survive environmental changes involves high genetic diversity, the ability to reproduce sexually in case of asexually reproducing species, and phenotypic plasticity. Genetic diversity enhances a species' ability to adapt to new conditions, and sexual reproduction can introduce new gene combinations that may offer better survival strategies during rapid environmental shifts. Furthermore, phenotypic plasticity, the ability of an organism to change its phenotype in response to environmental changes, plays a crucial role in survival. For example, the crystalline iceplant adjusts its water needs based on environmental availability, which has allowed it to thrive in diverse environments globally.
Conservation strategies must be proactive, allowing species to adapt at their own pace to prevent extinction due to climate sensitivity. This may include ensuring unfragmented habitats to enable species to shift their ranges in response to climate change, as fragmented habitats can prevent migration to suitable areas, leading to potential extinction.

For example Sialic acid, Glucosamine.The sugars like glucose, fructose, lactose are examples of simple carbohydrates.Therefore, sugar is an important backbone structure of amino acids and carbohydrates.
To learn more about sugars and amino acids follow the given link:
https://brainly.com/question/19485546
Atoms in sugar molecules contain carbon, hydrogen, and oxygen, which are essential for forming amino acids and other macromolecules. Carbon's ability to form covalent bonds allows it to serve as the backbone for complex molecules like proteins.
Atoms in sugar molecules contain carbon, hydrogen, and oxygen, which are fundamental for building more complex molecules like amino acids and other large carbon-based macromolecules.Carbon atoms can form covalent bonds with up to four different atoms, allowing them to create complex chains and rings that serve as backbones for biological macromolecules.For instance, sugars can contribute carbon skeletons to form amino acids through various biochemical pathways.These amino acids then join together to form proteins, which are critical for the structural and functional components of cells.In these biochemical transformations, dehydration reactions often occur, where water is removed to join smaller molecules into larger ones. This process is vital for forming large molecules like polysaccharides, nucleic acids (DNA and RNA), and proteins from their respective monomers—simple sugars, nucleotides, and amino acids.

How many trophic levels are there in the following food web
Answer: A.4
Explanation:
The food web provided in the image, there are C.3 trophic levels. Therefore ,C.3 is correct .
Producer: Grass is the producer at the base of the food web, as it can produce its own food through photosynthesis.
Primary Consumer: Worms are the primary consumers, as they consume the producers (grass) directly.
Secondary Consumer: Spiders are the secondary consumers, as they consume the primary consumers (worms).
The robin is not part of the food web as it does not directly feed on the worms.
Trophic levels are the different feeding positions in a food chain or web. They are numbered starting with the producers at the bottom, then the primary consumers, then the secondary consumers, and so on.
The energy in the food web flows from the producers to the primary consumers to the secondary consumers.
At each level, some of the energy is lost as heat, so there is less energy available at each higher trophic level. This is why there are typically no more than four trophic levels in a food web.

describe two properties of an exchange surface that would facilitate rapid diffusion rates
molecules and gaseous
The diffusion rate across an exchange surface is dictated by the extent of the concentration gradient and the surface area and thickness of the plasma membrane. A higher concentration gradient and larger surface area promote rapid diffusion, whilst a thicker plasma membrane slows down diffusion.
Explanation:Two properties of an exchange surface that would facilitate rapid diffusion rates are the extent of the concentration gradient and the surface area and thickness of the plasma membrane.
The extent of the concentration gradient is a key determinant of the diffusion rate. The greater the difference in concentration between two regions, the faster diffusion occurs. On the other hand, when the distribution of the material approaches equilibrium, the diffusion rate tends to decrease.
The surface area and thickness of the plasma membrane also affect the rate of diffusion. A larger surface area enables more materials to diffuse simultaneously across the membrane, thereby increasing the diffusion rate. Conversely, a thicker membrane inhibits the passage of materials, leading to a slower diffusion rate. This principle is applied in cells, where surface area-to-volume ratios are used to predict which cell(s) might eliminate wastes or procure nutrients faster by diffusion.

what is the principal source of dissolved substances in the ocean
weathering
outgassing
infiltration
vaporation
Pretty sure it’s weathering but not 100%
Answer:
infiltration
Explanation:
As Na and Cl make up much of the dissolved common salts found in the ocean waters, the element in the earth's crust can be easily be dissolved in the rain and river and get carried away from the runoff of the river. Infiltration is process by which water on the ground enters the soil. The porosity of the soil particles on land water determine the infiltration capacity and thus are a major source of dissolved sediments in water bodies. Also, rainfall influences this rate of sediment flows in water all the organic and inorganic matter in the soil is mainly composed and collected from the rain and discharge rate of the soil. Weathering produces mass wasting and erosion of the landforms from the above and thus indirectly related to the dissolved content. Inner Planets - Outer/Giant Planets

This energy comes from moving object, or objects that have stored energy. * sound energy chemical energy electrical mechanical
Motion energy, or the more common term, mechanical energy is the energy stored in objects.
The more an object moves faster, the more energy is stored. Some examples of motion energy include wind, a flowing river, a moving car, or a person running.
Final answer:
Mechanical energy is the energy associated with moving objects or storing energy, such as in kinetic or potential forms. Other forms like chemical, sound, and electrical energy can be transformed into mechanical energy. A car's movement exemplifies kinetic energy, while a compressed spring showcases potential energy.
Explanation:
The question refers to energy that comes from moving objects or stored energy sources. This type of energy is commonly known as mechanical energy, which is the sum of kinetic and potential energy in an object. Kinetic energy is the energy of motion, while potential energy is stored energy that is ready to be converted into other forms. For instance, a moving car has kinetic energy, and a compressed spring has potential energy.
Other forms of energy mentioned include sound energy, which involves the vibrations of matter; chemical energy, associated with the arrangement of atoms in molecules such as in food or fuel; and electrical energy, coming from the movement of electrons. Each of these forms of energy can be converted from one to another, like chemical energy converting to mechanical to power a car, or electrical energy converting to light in a bulb.
Understanding these forms of energy and their conversion is essential. For example, when you use a battery, it releases chemical energy which is then converted into electrical energy to power devices. Similarly, when you speak, your vocal cords vibrate to produce sound energy.
