The correct answer is protein.
Proteins are macromolecules composed of amino acids with the wide range of structures. Protein functions are diverse:
• structural proteins-maintaining the cell shape, (for example, proteins are structural elements in connective tissues like cartilage and bone in vertebrates),
• Enzymes - catalyze the biochemical reactions in cells-.
• Monitors- changing their activity in response to metabolic signals
• Part of the extracellular matrix or involved in intercellular communication…
Answer:
Genetic variation is a term used to describe the variation in the DNA sequence in each of our genomes. ... Individuals of a species have similar characteristics but they are rarely identical, the difference between them is called variation
Explanation:
Answer:
Kidneys are the important organ of excretion. Human kidneys are bean shaped located below the rib cage. Different vessels are involved in the transportation of blood from the abdominal aorta and back to the inferior vena cava.
The order of blood vessels are:
The blood enters in the aorta and and moves to the renal artery. Then the blood moves to the interlobar artery via segmental artery. The blood enters in the afferent glomerular arteriole from the arcuate artery and cortical radiate artery. Glomerulus receive the blood from the afferent glomerular arteriole. Then, the blood moves to the efferent glomerular arteriole. The blood then enters in the cortical radiate vein via peritubular capillaries and vasa recta. The blood moves back to the inferior vena cava from the arcuate vein, interlobar vein and renal vein.
Answer – D. RNA
Like proteins, Ribonucleic acid is another kind of organic molecule that also acts as a catalyst for chemical reactions. Asides acting a catalyst for chemical reactions, proteins have a wide variety of functions that they perform in in living cells.
Answer:
SENSORY CORTEX
Explanation:
The sensory cortex is the part of the brain that works on information referring to touch (called somatosensation) and other sense of feelings.
More specifically, the somatosensory cortex has a responsibility of processing touches in our body
