Answer:
The correct answer is b RNA polymerase is responsible for unwinding the DNA double helix and for catalyzing the formation of phosphodiester bond between nucleotides.
Explanation:
DNA double helix is unwound by the catalytic activity of helicase or dna B by using the energy derived from the hydrolysis of ATP.
RNA polymerase helps in the polymerization of nucleotides b the formation of phosphodiester linkage present in RNA.
Answer:
THYROID GLAND
Explanation:
Thyroid gland functions in metabolisms by activities of thyroid cells.This cells withdraws Iodine from metabolites and combine it with amino acid tyrosine for productions of Thyroid hormones:
ThyroxineT3,(20%)
TriiodothyronineT4(80%). This production is under the influence of Thyroid stimulating hormones,regulated by the pituitary gland,
T3 and T4 increase calorinogenesis, (liberation of heat from digestion to supply energy,and oxygen consumption of the heart.)
Deficiency of thyroid hormones are goiters, hypothyroidism, and hyperthyroidism
Answer:
Jennifer observes a weather map showing tomorrow's weather. She predicts that air will travel from the high pressure system to the low pressure system, causing wind. The wind will carry moisture since it is coming from the ocean.
Explanation:
Winds refers to the movement of air which are produced due to differences in air pressure.
These pressure differences are to uneven heating of the earth by the sun. Due to the uneven shape of the earth, regions around the equator receive a fairly consistent heating from the Sun. However, with increase in latitude north and south, there is more uneven heating of the earth's surface by the Sun. When air is heated, warm air rises up to the atmosphere. This produces a pressure difference and subsequently cold air sinks downward to replace it. This constant air movement results in winds. The winds generated moves from a high pressure system to a low pressure system. The greater the pressure difference, the greater the wind force.
When warm air from land rises, air from the ocean in to replace it. The wind coming from the ocean is moisture-laden, and results in precipation on land.
A. lipids
There are different forms of lipids. The one described in the question is called triglyceride.
