Answer:
Explanation:
From the question, the total population = 171 i.e (80+71+21)
Genetic frequency therefore; BB = 71/171 = 0.42
Bb = 80/171 = 0.47
bb = 20/171 = 0.12
Allele frequency therefore;
Allele B = 0.42+(0.50×0.47) = 0.66
Allele b = (0.50×0.47)+0.12 = 0.36
Note all values were rounded up to two significant figures
Answer:
18
Explanation:
all the law is saying is that matter cant be created nor destroyed, so if 18 oxygen atoms are used, there will be 18 oxygen atoms in the end, no matter what, doesn't matter what they use it for or what
The person who is most likely to be interested in the research involving the transfer of energy by the organisms living in the ocean's hydrothermal vents is Everett Shock.
He along with his students tests and develops the thermodynamic data for the bio-molecules, minerals, and the aqueous solutes. The reactivity of the organic compounds is explored by them in the hydrothermal conditions. So, he is the most likely person to be interested in the said discovery.
Hence, the answer is 'Everett Shock'.
Explanation:
Amino acid-based hormones use a second messenger, cyclic AMP, but steroid hormones <u>complex inside the nucleus with a receptor and DNA to initiate protein synthesis</u>
Further explanation:
The endocrine system involves chemical signalling via the secretion of molecules called hormones into extracellular fluid. They bind to chemical receptors in order to cause specific changes in target cells, these lead to changes in the body's internal environment called homeostasis.
The endocrine system includes the thyroid, parathyroid, pituitary, pineal and adrenal glands along with other regions. The bone, adipose tissue, heart, pancreas and liver are a few of the regions of the body which show endocrine function.
Steroid hormones are mainly derived from the steroid molecule. They contain two types, sex steroids, and corticosteroids. Based on the receptors they bind to, these are further subdivided into:
- mineralocorticoids
- androgens
- glucocorticoids
- estrogens
- progestogens
They traverse the cell membrane and bind to intracellular reptors, forming complexes that regulate or switch on gene expression. The complex joins with hormone response elements, which are unique sequences of DNA to jump-start the transcription process within the cell.
