Answer:
D. Only the adrenal medullae
Explanation:
The adrenal medulla is the inner region of the adrenal gland. It consists of the modified sympathetic ganglion of the autonomic nervous system and develops from the same embryonic tissue as all other sympathetic ganglia. The cells of the adrenal medulla lack axons and are [present in the form of clusters around large blood vessels.
The chromaffin cells of adrenal medulla serve the endocrine function. These cells are innervated by sympathetic preganglionic neurons of the ANS. The adrenal medulla secretes epinephrine and norepinephrine which are called neurohormone as being secreted by neurons.
Answer: Nucleotides are the monomers used for DNA synthesis. The mix also contains a template, DNA taq polymerase, buffer, reverse and foward primer and magnesium ions.
Explanation:
A PCR master mix is a premixed solution that has all of the components for a Polymerase chain reaction (PCR). This reaction is a laboratory technique that amplifies small fragments of DNA into millions of copies.
The master mix used for that contains dNTPs (nucleotides). In the DNA there are four types of nucleotides that are differentiated by the nitrogen base they have: adenine (A), guanine (G), cytosine (C) and thymine (T).
<u>Since nucleotides are the monomers that make DNA, they are found in the mix because they are the material for DNA synthesis.</u>
The reaction mixture also requires;
- DNA template, the sequence of DNA to be amplified
- DNA taq polymerase, a heat resistant enzyme that assembles nucleotides into a new DNA
- Salt buffer, for an optimum ionic environment and pH
- Oligonucleotide primers (reverse and foward), pieces of DNA complementary to the template. Each hybridizes with one of the DNA chains.
- Magnesium ions, a catalyst required by DNA polymerase to work
Answer:
Some political scientists need a background in marine science so they can understand marine life and can make policies in an attempt to regulate human behavior to protect the ocean and ocean life. Marine scientists must be able to understand the diverse life in the ocean

Answer:
K = 9.620 × 10⁻⁶
Explanation:
From the given information:
Temperature T= 6° C
= (273 + 6)K
= 279 K
The correct and well presentation of the reactions are:
1.
⇆ oxyluciferin + light ΔG₁°
2. ATP ⇄ AMP + PP
ΔG₂° = -31.6 kJ/mol
The overall ΔG° = -4.80 kJ/mol
Let's first determine the ΔG₁° for the equation (1)
ΔG° = ΔG₁° + ΔG₂°
- ΔG₁° = - ΔG° + ΔG₂°
ΔG₁° = ΔG° - ΔG₂°
ΔG₁° = ( -4.80 - (-31.6) ) kJ/mol
ΔG₁° = 26.8 kJ/mol
Using the formula:
ΔG° = -RTIn K


K = antilog (-5.017)
K = 9.620 × 10⁻⁶
I think you're talking about histones. Histones are proteins found in eukayotic cell nuclei. Histones are what DNA wrap around so it fits inside the nucleus and helps with the formation of chromosomes.
