Explain how the behavior of solitary bees and social bees increases their chances of reproductive success.
Answer:
Working alone, the female collects building materials for the nests and food for the larvae, then builds an individual cell for each egg. She lays each of her 20-30 eggs on top of a ball of pollen stuck together with nectar. She builds a partition wall, then repeats the process until the tube or hole is full.

Why do organisms with one color produce few offspring than those with multiple colors?
Answer:
atural selection can cause microevolution (change in allele frequencies), with fitness-increasing alleles becoming more common in the population.
Fitness is a measure of reproductive success (how many offspring an organism leaves in the next generation, relative to others in the group).
Natural selection can act on traits determined by alternative alleles of a single gene, or on polygenic traits (traits determined by many genes).
Natural selection on traits determined by multiple genes may take the form of stabilizing selection, directional selection, or disruptive selection.

d. Shearing
Explanation:
STRESS : A state of mental or emotional strain or tension resulting from adverse or very demanding circumstances.
COMPRESSION : If a cylinder is compressed under the action of the applied force, the restoring force per unit area is known as the compressive stress.
TENSION : Mental or emotional strain. OR The state of being stretched tight.
SHEARING : A deformation of a material substance in which parallel internal surfaces slide past one another.

1. Describe the flow of energy to killer whales.
2. If killer whales were removed from the ecosystem, how would it
impact the other organisms?
3. What would you expect to happen if the algae population
increased?
4. Describe how the fish population would change if the seal
population decreased.
The killer whales have a tremendous flow of energy as the whale eats and consume more protein and a nutrient-rich diet.
What is a killer whale?1. A killer whale is also called an Orca and a toothed whale. The whale is the largest member of the killer whale specie and has tremendous flow of energy due to they fed on small and large aquatic forms.
2. If the whale is removed from the ecosystem then the food chain will get disturbed and there will large growth of other species of fish will be in abundance.
3. If the algae increase the oxygen in the lakes and seas will be depleted and other species will be impacted as the fish popuaion may get reduced.
4. if there a change in seal popualtion then popualtion of fish will double itself and again distub the food web.

what is the structure identified by the arrow in the diagram below?
A. Chromosome
B. DNA Strand
C. Gene
D. Cell
Answer:
A.}Chromosome
Explanation:
According to the research, a chromosome is the structure identified by the arrow in the diagram below.
What is a chromosome?It is a condensed structure of DNA (deoxyribonucleic acid) present in cells that contains genetic information.
In this way, they have a double structure, composed of two structures parallel to each other and joined by a centromere, called chromatids, in each of the "arms" of a chromatid the genes are located.
Therefore, we can conclude that according to the research, a chromosome is the structure identified by the arrow in the diagram below.
