Explanation:
Gene flow is the exchange of alleles between two or more populations.
Gene flow is the exchange of alleles between two or more populations. For this reason it is sometimes referred to as allele flow or gene migration. While migrating animals often carry new alleles from one population to another, they must interbreed with the new population for gene flow to occur

In the predator-prey relationship between lions and zebras, when the population of zebras is great, the population of lions will
A. decrease
B. increase
C. stay the same
D. die off
Answer:
B. Increase
Explanation:
Since lions rely on zebras as a food source, if there are more zebras (more food sources for the lions), there will also be more lions. Therefore, the lion population would increase initally.

When and where would you expect to find the highest rate of primary productivity
Answer: Net primary productivity is the amount of gross primary productivity remaining after respiration, which is about 40 and 85 percent. Sloughs and marshes, as well as tropical rain forests, possess the highest rates of net primary productivity; deserts have the lowest.
Explanation:
I explained on the top-
The highest rate of primary productivity in terrestrial environments takes place in swamps and marshes and in tropical rainforests, and in aquatic environments it takes place in algal beds, estuaries, and reefs.
• In ecology, primary productivity refers to the rate at which conversion of energy to organic substances takes place by the photosynthetic producers that attain energy and nutrients from the sunlight, and chemosynthetic producers that attain chemical energy via oxidation.
• The majority of the energy assimilated by plants via the process of photosynthesis is not stored as organic substance, however, is utilized at the time of cellular respiration.
• In the process, the organic components like proteins, carbs, and fats are dissociated to provide energy in the form of ATP for the metabolic needs of the cells.
• The energy not utilized is stored in the tissues of the plants for future use and is known as the net primary productivity.
• The highest net primary productivity in terrestrial environments takes place in marshes and swamps and in tropical rainforests, and in aquatic environments it takes place algal beds, estuaries, and reefs.
These environments are mainly critical for the sustenance of global biological productivity.

Consider this plant cell. The organelles in a plant cell are labeled. Part G is the middle layer of the cell. Which organelle is labeled G?
Answer:
Hi. You didn't show the picture that shows organelle G, but since you showed that organelle is the middle layer of the cell, we can say that it is the plasma membrane.
Explanation:
In general, we can state that the plant cell has three layers, the cell wall, the plasma membrane and the cytoplasm. The cytoplasm is the inner layer, where most of the organelles and the cell nucleus are located. Above the cytoplasm is the plasma membrane, which is semi-permeable and promotes the regulation of the entry and exit of substances from within the cell. Above this membrane is the cell wall, which is an impermeable structure that protects the cell and promotes its rigidity. In this case, we can consider that the middle layer of the cell is the plasma membrane.

Starch is a polysaccharide used as a component of cell walls in plants.
True
False
Answer:
false
Explanation:
is type of carbohydrates
False. Starch is a polysaccharide used as an energy storage molecule in plants, but it is not a component of cell walls.
What are structural component of cell wall?Cell walls are structural components found in the outermost layers of cells in plants, fungi, and some bacteria. They provide support and protection for the cell, and are composed of a variety of different biomolecules, including cellulose, pectin, and lignin.
Starch, on the other hand, is a complex carbohydrate that is synthesized and stored in the cells of plants, particularly in the seeds, roots, and tubers. It is made up of long chains of glucose molecules and is used by plants as an energy source, particularly during times when the plant does not have access to light for photosynthesis. Starch is not a component of cell walls.

Explain how different types of cells help organisms live and grow?
Different types of cells have different jobs that are necessary to keep organisms alive.
Different types of cells are only found in specific types of organisms.
Cells are necessary in order for all organisms to grow big and hunt for their food source.
Cells provide support for all organisms to be able to move.
Answer:
Different types of cells have different jobs that are necessary to keep organisms alive. And cells also give the living animal more support. They also hold the genetic information of that organism in their nucules. This is with most cells but bacteria cells do not contain nucules.
