Answer:
Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.
Clotting cascade refers to the series of reactions which take place simultaneously and result in blood clotting. The clotting cascade is a complex set of negative feed back mechanism which is used by the human body to maintain homeostasis. The clotting cascade can be triggered either by intrinsic or extrinsic release of chemical mediators. The reaction occur in this order:
Intrinsic factor < activation of common clotting pathway < platelet lipids are released < prothrombin < fibrinogen < fibrin formation < stabilized fibrin clot.
Two examples of anticoagulant medication that affect the pathway are heparin and warfarin
Answer: The right answer is -
A) Gene flow
Explanation:
Gene flow is a process of gene migration or the transfer of gene variant (also called allele, which is responsible for genetic variation in population) from one population to another population.
As a consequence of gene migration, new alleles are introduced or added in the already existing population, thereby increasing genetic diversity.
Thus, option A) is the right answer.
<span>The answer would be: requires an outside energy source for a nonspontaneous chemical reaction to occur

Answer:
The greatest of environmental factors on phenotype is on phenotypic plasticity, phenotypes that may change due to changes in the environment; ex: snowshoe hare have brown-colored fur in summer/spring and white fur in winter. Environmental factors may affect gene expression which may result in normal/abnormal phenotypic changes.
