Answer: <span>femoral; crural
In referring location/region you can use proximal or distal. Proximal means closer to the body. It's the opposite of distal that would mean further to the body
Femoral (or thigh) is located nearer to the body than crural (or leg).</span>
Answer:
Tissues
Explanation:
Tissues are organized group of cells carrying out specific coordinated functions. They are organizational structures that lies between cells and organs. A group of cells binds together using specialized proteins forming a tissue, furthermore, a group of different tissues are the building blocks for organs and plant structures creating a complete system.
Answer: a) substrate and cofactors b) covalent modification
Explanation:
Metabolic pathways involve all the chemical processes takes place in the enviornment or in an organisms.The metabolic pathways are controlled through the catalytic activities of enzymes.
The availability of enzyme is regulated by substrate and cofactors present in enzyme and enzyme activity is commonly regulated via covalent modification.
Enzymes are highly selective in nature and bind to a specific substarte only. The active site in enzyme binds with the substrate to form enzyme substrate complex. Coactors assist the enzyme activity, without cofactor enzyme can not perform its activity.
Hence enzyme availibility is regulated by substrate and cofactors regulates.
Covalent modifications regulates activity of enzyme as it involves addition and removal of chemical group to synthesis required protein. It can change the chemical properties of the site by targeting one or multiple amino acid.
Thus the correct answer is a) substrate and cofactors b) covalent modification
The answer is Mitochondria

<span>The papillary region</span> is the structure that house Meissner's corpuscles, free nerve endings and capillary loops.
<span>This region is the superficial portion of the dermis, about 1/5 of the dermis. The papillary region consists of areolar connective tissue with thin collagen and fine elastic fibers.</span>
