The nervous and the endocrine system are tightly linked together.
The main reason for this linkage is due to the connection of the hypothalamus (nervous system) and the hypophysis (a gland in the endocrine system)
The hypophysis is the ''controller'' of all of the other endocrine glands.
The connection between the hypothalamus and the hypophysis enables the nervous system to control the hormone levels of all of the major endocrine glands in the body.
The hypothalamus releases hormones into the bloodstream that leads to the hypophysis. These hormones induce a release of hypophysis hormones that enter the bloodstream and when they reach the target gland (for example pancreas) these hormones induce the release of the hormones of that gland (in the case of the pancreas, insulin).
The hypothalamus monitors the concentration of hormones in the blood, and a high level of a certain hormone blocks the release of the hypothalamus' hormones. Therefore, a high level of insulin blocks a cascade of hormone release that starts in the hypothalamus that leads to its release in the pancreas.
Answer:
true
Explanation:
mutations deal with chromosomal changes, and while they might not always be reflected in the phenotype.. the genotype does change
Answer:
Explanation:
They may have som bad side effects such as nausea, indigestion, vomiting etc. Also the bacteria change or adapt if not taken correctly so they are no longer affected by the antibiotic.
Answer:
100% of the progeny will be speckled
Explanation:
<u>Available data:</u>
- Three colors: dark brown, light brown, and speckled.
- The genotypes for these colors are BB for dark brown, bb for light
brown, and Bb for speckled.
Cross: dark brown crab with a light brown crab
Parentals) BB x bb
Gametes) B B b b
Punnett square)
B B
b Bb Bb
b Bb Bb
F1) Genotype:
4/4 = 100% of the progeny will be heterozygous for the trait, Bb
Phenotype:
4/4 = 100% of the progeny will be speckled
Acetylene (C2H2) has a triple bond between the two carbons. So 3 pairs of electrons. Biomed is talking about ethylene (C2H4).
