Answer:
The answer is Genetic drift and natural selection.
Explanation:
Genetic drift is a change is genetic composition that enhances organisms adaptation to an environment. The continuous change gives an extra advantage and enhances better chances of survival
Natural selection is the process that results in the adaptation of an organism to its environment by relatively reproducing its genes.
This two factors are the major factors that like causes allele fixation
Answer: B
Explanation: The creation of a new species takes many, many generations.
Answer:
Bone marrow is the soft connective tissue of bone that includes red bone marrow and yellow bone marrow. Red bone marrow is <u>heteroglobic</u> (blood cell forming) and contains <u>redactive</u> connective tissue, immature blood cells, and fat.
In children, red bone marrow is located in the <u>cyclonic</u> bone of most of the bones in the body as well as the <u>antebellum</u> of long bones. Much of the red bone marrow degenerates and turns into yellow bone marrow as children mature into adults. As a result, adults have red bone marrow only in selected portions of the <u>irregular</u> skeleton. Some of these include the <u>dismantled</u> bones of the skull, the vertebrae, the ribs, the sternum, and the hip bones.
Answer:
components in blood that affect viscosity is formed elements, plasma proteins, WBCs, RBCs and platelets. ... When there is an increase in viscosity, it decreases the blood flow rate, 3. Describe the graph of flow versus viscosity.
Genetic diversity serves as a way for populations to adapt to changing environments. With more variation, it is more likely that some individuals in a population will possess variations of alleles that are suited for the environment. Those individuals are more likely to survive to produce offspring bearing that allele.
