_______ is located in the anterior neck produces key hormones for metabolism

Lapatulllka [165]

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

What needs to happen for recessive traits to be observed in an organism?

ANEK [815]

Answer:

For recessive traits to be observed, dominant genes must be absent.

Explanation:

There are 3 possibilities for the genes: AA, Aa, aa.

in both AA and Aa, there is a dominant gene present. If a dominant gene is present, it will always show the dominant trait.

In aa, there is no dominant gene present, and there are only recessive genes. Because of this, the recessive trait is observed!

Which of the following is true for DNA but not RNA? Release of PPi from the monomer provides the energy for polymerization. It h

Maru [420]

Explanation:

All are true for both DNA and RNA because they are release of ppi from the monomer provides the energy for polymerization.
Proteins, lipids and complex starches (polysaccharides), nucleic acids are one of the four significant sorts of macromolecules that are fundamental for every known type of life.
The nucleic acids comprises of two significant macromolecules, Deoxyribonucleic corrosive (DNA) and ribonucleic corrosive (RNA) that convey the hereditary guidelines for the improvement,
The center structure of a nucleic corrosive monomer is the nucleoside, which comprises of a sugar buildup + a nitrogenous base that is joined to the sugar buildup at the 1′ position.
The sugar used for RNA monomers is ribose, while DNA monomers use deoxyribose that has lost the hydroxyl useful gathering at the 2′ position of ribose.
Four nitrogenous bases that are joined into the standard DNA structure. These incorporate the Purines such as Adenine (An) and Guanine (G), and the Pyrimidines.Cytosine (C) and Thymine (T).
RNA utilizes indistinguishable nitrogenous bases from DNA, aside from Thymine. where is the Uracil (U) found in the RNA nucleotide.
The nucleotide ,When the one of phosphate group are connected to a nucleoside at the 5′ position so that is formed the sugar buildup.
The joining of one phosphate frames a nucleoside monophosphate, the fuse of two phosphates shapes a nucleoside diphosphate, and the fuse of three phosphates frames a nucleoside triphosphate.
