Answer:
The peas with the purple flowers were dominant and the peas with the white flowers were recessive.
Explanation:
In Gregor Mendel's study, he studied pea plants with purple flowers and white flowers. The purple flowers were dominant, and whenever the allele for a purple flower was present is was visible on the plant. The white flowers were recessive because if an allele for a purple flower was present, then the flower was purple. The flowers were only white if both alleles were for white flowers.

Use the model here to describe the transfer of matter and flow of energy from one trophic level to another within an ecosystem.
Answer:
Thanks to light energy or chemical energy, the producers, which are on the base of the pyramid, produce their food. Then, the primary consumers eat the producers. The secondary consumers eat the primary consumers. Lastly, the tertiary consumers eat the secondary consumers. The producers process the residues from all the levels obtaining their food and starting the cycle again. Each level in the pyramid has the matter that the animals in the next level will consume. The animals digest the food and break it down into small components that the body uses as energy and for its structure.
The flow of energy from one level to the other is not efficient. Part of it is lost as heat or due to not good digestion. As a result, the energy transferring as we ascend in the pyramid is lower, making it impossible to continue the pyramid since there is not enough energy to nourish another level.
Explanation:
There is a loss of matter from one level to another since some are lost as fecal matter because it could not be processed. The same process happens with the energy from one level to the other. The energy decreases since a part is lost as heat, and the animal uses a part of it to stay alive. As a consequence of this decrease in energy, the higher levels receive less energy than the ones in the lower part of the pyramid.
The flow of energy from one trophic level to another within an ecosystem. Part of it is lost as heat or due to not good digestion.
What is the relationship between Biodiversity and ecosystem?Biodiversity has three levels - ecosystem, species and genetic diversity. Therefore, Biodiversity can be defined as the variability among living organisms involving terrestrial, marine, and other aquatic ecosystems, genes and alleles in a species and their ecological complexes such as diversity within species, and between species of the ecosystems.
As a result, the energy transferred as we ascend in the pyramid is lower, making it impossible to continue the pyramid since there is not enough energy to nourish another level.

Suppose your friend investigated the color of pea pods and concluded that green pods (G) were dominant over yellow pods (g). What experimental evidence would be needed to support this conclusion?
This information can be confirmed by obtaining the observed phenotypic frequency in the second generation (F2) of a genetic cross between pure lines.
The observed phenotypic frequency is the number of individuals that have a specific observable trait (in this case, green pods or yellow pods).A dominant trait produces a 3:1 phenotypic rate in the second generation (F2) of a genetic cross between two pure lines.In conclusion, this information can be confirmed by obtaining the observed phenotypic frequency in the second generation (F2) of a genetic cross between pure lines..

A) A small amount of the evaporation and precipitation
B) Most of the evaporation and precipitation
C) Most of the evaporation but a small amount of the precipitation
D) A small amount of the evaporation and most of the precipitation
Answer:
C. Evaporation occurs when the ocean water comes up to the clouds and change it from a liquid to a gas, however precipitation occurs just a tinsy bit because precipitation is actually like rain, hail, sleet, etc... so that doesn't happen all the time

Mary is a carrier for a mutated gene that causes sickle cell disease. Which of the following statements is true about Mary?
A. If Mary has a child with someone who has sickle cell disease, there is a 50% probability their child would have the disease.
B. If Mary has a child with someone who does not have a mutated sickle cell allele, there is a 25% probability that the child will be a carrier.
C. If Mary has a child with someone who is also a carrier, there is a 50% probability their child would have the disease.
D. Mary has sickle cell disease.
The statement is true about Mary is If Mary has a child with someone who has sickle cell disease, there is a 50% probability their child would have the disease. Thus, option A is correct.
What is Sickle cell anemia?
Sickle cell anemia is a hereditary disease which provides less oxygen to cells due to a change in the shape of red blood cells which fails to carry oxygen to cells.
In sickle cell anemia, the effected or mutated part is the beta gene that normally makes hemoglobin but due to the mutation in the amino acid, the protein formed is defected and fails to perform its normal function.
As mentioned above, it is a heredity diseases and pass from generations to generations.If Mary has a child with someone who does not have a mutated sickle cell allele, there is a 25% probability that the child will be a carrier.
Therefore, The statement is true about Mary is If Mary has a child with someone who has sickle cell disease, there is a 50% probability their child would have the disease. Thus, option A is correct.

Which health factor is an individual unable to change?
A-nutrition
B-environment
C-inherited genes
D-cholesterol levels
Answer:
C-inherited genes
Explanation:
The health factor that an individual is unable to change is inherited genes, which is in Option C, as inherited genes are passed down from parents to their offspring and can influence an individual's health.
What are inherited genes?Inherited genes are a fundamental aspect of an individual's biology that they are born with and cannot change. These genes provide the blueprint for the development and functioning of various systems in the body, including the immune system, cardiovascular system, and nervous system. Some genetic traits can increase an individual's risk of developing certain diseases or conditions, while others may protect against certain health problems. While individuals cannot change their inherited genes, they can take steps to manage their health based on their genetic risk factors.
Hence, a health factor that an individual is unable to change is inherited genes, which is in Option C.
