The correct answer is sex linkage.
Sex linkage refers to the phenotypic expression of an allele, which relies upon the gender of an individual and is directly associated with the sex chromosomes. These genes are regarded sex-linked as their expression and patterns of inheritance vary between the males and females. The sex linkage cannot be the same as genetic linkage, the sex-linked genes can be associated genetically.
The right answer is B. controlling the flow of blood to the skin
When the body temperature is below the set point, the hypothalamus activates several thermogenesis mechanisms:
* Vasoconstriction on the vessels near th skin by the sympathetic nervous system to reduce thermal exchanges between the skin and the surrounding environment.
* And increase in heat production:
-by muscular activity:
-by the metabolism:
Answer:
A) hypertonic, out of the cell.
Explanation:
When cells are exposed to high levels of salt (sodium chloride) they lose water by osmosis and shrink. The cytoplasm condenses and the movement of cellular components, such as the cytoskeleton and organelles, stops. Cells adapt to high salt by quickly importing salt in order to attract water and regain volume, at the expense of increased salt concentration. Unlike cell volume, the movements of cellular components are slow to recover and, depending on the dose of salt, may not recover fully.
The leaf needs the sun to grow and gain energy. the insect then eats the leaf and gets its nutrition and energy.
