Answer:
proteins
Explanation:
carbohydrates and fats are made from three basic molecules: Carbon, hydrogen and oxygen. All proteins contain an element not found in carbohydrates and fats, nitrogen and some proteins also contain sulfur. The main unit that builds all carbohydrates is monosaccharide, or sugar while triglycerides make fats and proteins consist of amino acids.
Answer:
Rodents and primates.
Explanation:
Given diagram represents a phylogenetic tree, which shows evolutionary relationships between organisms. The nodes in the tree denotes the ancestral lineage, while the tips of its branches denotes descendants evolved from that ancestor.
According to given tree, rodents and primates share most common recent ancestor as these branches are evolved from a common node and so, they are most closely related organisms.
It’s mechanical because it’s fs not weathering
<span> They are unable to pass through the plasma membrane and have different methods of action. They attach to their receptors in the target cell surface and influence activity within the cell through cytoplasmic intermediates called second messengers. </span>
<span>The two most important messengers are cAMP and inositol triphosphate. </span>
<span>Cyclic AMP: ATP is converted into cAMP after a series of reactions on the plasma membrane following the attachment of the hormone to the membrane. cAMP relays the signal from the membrane to the metabolic machinery of the cytoplasm. </span>
<span>Inositol Triphosphate: Involves the use of Ca+2 that regulates cellular protein activity.
