Answer:
The nervous system sends signals that cause the adrenal glands to release hormones. This statement describes two organ systems working together to make an animal run away from danger
How do adrenal glands and nervous system work together?
The pituitary and adrenal glands create hormones that govern growth, stress, sexual function, and chemical equilibrium in the body.
The hormones adrenaline and norepinephrine, which are responsible for human stress reactions, are produced by the adrenal glands.
Catecholamines are adrenal medulla hormones that also act as traditional neurotransmitters in the autonomic nervous system.
The adrenal medulla is neural tissue that has been changed, and its activity is controlled by a direct neural input.
As a result, the medulla works similarly to a sympathetic ganglion.

i read the book
Phenylthiocarbamide (PTC), also known as phenylthiourea (PTU), has the unusual property that it either tastes very bitter or is virtually tasteless, depending on the genetic makeup of the taster. There is a single gene which codes for a protein found in our tongues. PTC will bind with the protein if it present and a person will taste it. If the protein is not present, PTC will not bind and a person cannot taste it. The ability to taste PTC is often treated as a dominant genetic trait. The dominant allele, T, causes a person to be able to taste PTC, and the recessive allele is represented as t. Assume that a population is in Hardy-Weinberg equilibrium and 16 individuals out of 100 are unable to taste PTC.
What are the allele frequencies of T and t in this population?
A. The allele frequency of T is 0.80, and the allele frequency of t is 0.20
B. The allele frequency of T is 0.84, and the allele frequency of tis 0.16.
C. The allele frequency of T is 0.00, and the allele frequency of t is 0.40
D. The allele frequency of T is 0.50, and the allele frequency of t is 0.50.
Answers
Answer:
B. The allele frequency of T is 0.84, and the allele frequency of t is 0.16.
Explanation:
The Hardy-Weinberg equation is:
p2 + 2pq + q2 = 1
Where:
p = the frequency of the dominant allele
q = the frequency of the recessive allele
1 = the total number of alleles
Given that 16 individuals out of 100 are unable to taste PTC, we can calculate that the frequency of the recessive allele, q, is 0.16. We can then use the Hardy-Weinberg equation to solve for the frequency of the dominant allele, p:
p2 + 2pq + q2 = 1
p2 + 2p(0.16) + (0.16)2 = 1
p2 + 0.32p + 0.0256 = 1
p2 + 0.32p - 0.9144 = 0
(p + 0.32)(p - 2.84) = 0
p = -0.32 or p = 2.84
Since the allele frequencies must add up to 1, we know that p cannot equal -0.32. This leaves us with p = 2.84. Therefore, the allele frequency of the dominant allele is 2.84, and the allele frequency of the recessive allele is 0.16.

What happens at the end of translation?
Answers
Answer:
Explanation:
Translation ends in a process that called ( termination) .
Termination happens when a stop codon in the mRNA (UAA , UAG , UGA ) enters the A site.
Stop codons are recognized by proteins called release factors,
which fit neatly into the P site (Though they aren't tRNAs ) .
Answer:
Termination
Explanation:
The process of transcription involves creating RNA from a DNA template.
In the last stage of transcription, known as termination, the DNA-RNA hybrid separates from the original strand of RNA. Recognizing the point at which no more bases should be added is necessary for terminating transcription. The DNA sequence needed for termination is known as the terminator and consists primarily of the poly U region. At this point, the enzyme stops adding nucleotides to the developing RNA strand and separates from the DNA template.
This process is used by bacteria in two different ways.
1. Initial termination ( Rho - independent )
In this instance, the transcript strand creates a hairpin shape by creating G-C rich inverted repetitions, which permits the creation of a hair-pin structure at this position. However, the transcription bubble is insufficient to support the DNA-RNA hybrid, and the RNA polymerase is then knocked off.
2. Rho — DEPENDENT
Rho is a protein that is involved in this kind of termination process. The RNA-stimulated helicase Rho factor, which disrupts RNA-DNA hybrids, is ATP dependent. At the rut location, this Rho protein binds to RNA ( Rho utilization site ). Rut has to be free of the ribosome in order to bind Rho. When RNA polymerase stops moving at the rut site, Rho protein catches the polymerase and uses helicase activity to separate the DNA-RNA hybrid.

How is a hydrolysis reaction the opposite of a condensation reaction?
Answers
Condensation processes include the formation of bonds between molecules and their combining, with the consequent loss of a water molecule. Since a chemical bond is being broken by the addition of water and frequently with the help of an enzyme that catalyzes the reaction, hydrolysis is related with bond breaking.
A hydrolysis reaction is the opposite of a condensation reaction in terms of the chemical process involved. In a condensation reaction, two or more smaller molecules combine to form a larger molecule, releasing a water molecule as a byproduct.
This process is also known as dehydration synthesis because it removes water to form a bond between molecules.
On the other hand, in a hydrolysis reaction, a larger molecule is broken down into smaller molecules by the addition of a water molecule.
The water molecule is split into its components, with a hydroxyl group (-OH) attaching to one part of the molecule and a hydrogen ion (H+) attaching to the other part, effectively breaking the bond between the two subunits.
In summary, a condensation reaction builds larger molecules by removing water, while a hydrolysis reaction breaks down larger molecules by adding water.
