Answer:
Neural: faster and shorter in duration
Endocrine: slower and longer in duration
Explanation:
The nervous system is responsible for transmitting nerve impulses through the molecules that manufacture and secrete neurons, called neurotransmitters. This information is transmitted through the nervous way
The responses of the nervous system are fast, brief and very specific, associated with responses of movement and sensory perception
The endocrine system is characterized because it controls its functions through chemicals called hormones. It is responsible for very diverse functions, associated with metabolism and growth.
These responses tend to be slower than those of the nervous system but of longer duration, since it comprises functions that are regulated slowly.
Auto - troph
auto means self, troph means related to nutrition or feeding
autotroph
Answer:
Within double-stranded DNA, the nitrogenous bases on one strand pair with complementary bases along the other strand; in particular, A always pairs with T, and C always pairs with G. Then, during DNA replication, the two strands in the double helix separate.
Explanation:
The four nitrogenous bases of DNA are thymine, adenine, guanine, and cytosine. Guanine and cytosine are bound together by three hydrogen bonds; whereas, adenine and thymine are bound together by two hydrogen bonds. This is known as complementary base pairing.
Answer:
Calcium
Explanation:
Parathyroid hormone (PTH) is a hormone that is secreted by the parathyroid gland. It is the major regulator of the plasma concentration of calcium ions. It regulates calcium ions in the kidney, intestine and bones.
In the kidney, is involved in the re-absorption of calcium in distal ducts and the renal collecting duct, it is also involved in activating the conversion of 25-hydroxy vitamin D into 1,25-dihydroxy vitamin D (calcitriol).
In the intestine, PTH is involved in the absorption of calcium, by increasing vitamin D production.
In the bone, it helps in regulating calcium levels; when serum calcium level is low, PTH stimulates the activity of the osteoclast, to produce more calcium.
High blood pressure, is characterized by the narrowing of the aorta.
