Answer:
Cellular respiration is a complex biochemical process, whose main objective is to achieve that with the use of nutrient elements and in the presence of oxygen, energy, CO2, H2O and hydrogenation are produced as a final result. For vital reasons, since for the cell it can live and function, it needs energy, it is that the cells need the process of cellular respiration. In unicellular organisms, the process is simpler, since the cell membrane is in contact with the source of oxygen, either a liquid medium or an air medium.
In multicellular organisms, the process becomes more complex and much more dependent on multiple factors, because several mechanisms or events are needed, which guarantee oxygen and nutrients reach the different cells, degree of the degree of specialization that they have developed and from the place where they meet.
Answer:
A polygenic trait can be described as a physical trait which is influenced by more than one gene.
The three types of selection for a polygenic trait are:
1) Directional Selection: In a directional selection, one of the phenotype is favored in an ecosystem. As a result of this favoring, the allelic frequency changes and shifts in favor of this particular trait.
2) Stabilizing selection: It is a type of natural selection in which the intermediate trait is favored. The population carries a middle trait in abundance.
3) Disruptive Selection: Disruptive trait is a type of natural selection in which the traits on the extreme sides are favored. The intermediate traits are less favored.
Answer:
b) moderate temperatures and moderate amounts of precipitation
Explanation:
Temperate deciduous forest is characterized by moderate temperature and moderate amounts of precipitation. Temperate deciduous forest has four different seasons fall, summer, spring, and winter. The summer season is the longest therefore it has a moderate temperature.
In a year 30-60 inches precipitation occurs in temperate deciduous forest. Therefore moderate precipitation occurs in this forest. Precipitation occurs all over the year. The soil is highly fertile in this forest. They are found in Europe, China, the united states and Canada. So the correct answer is b.
D. Mutations will always impact an individual on some level
Most of these seem accurate or at least close to being accurate on how mutations affect genes however, some mutations won’t always impact an individual because some mutations are so minor. But this is my best guess
