60 POINTS!! PLEASE HELP!!When the level of blood testosterone has increased past its set point, a negative feedback signal will be sent to the hypothalamus.
Based on the diagram, what will be the result of this signal?
A) The hypothalamus will stop production of gonadotropin-releasing hormone. As a result, the production of follicle-stimulating hormone will increase and testosterone levels will decrease.
B)The hypothalamus will stop production of gonadotropin-releasing hormone. As a result, follicle-stimulating hormone will no longer be produced and testosterone levels will start to decrease.
C)The hypothalamus will stimulate production of gonadotropin-releasing hormone. As a result, the production of follicle-stimulating hormone will increase and testosterone levels will increase.
D)The hypothalamus will stimulate production of gonadotropin-releasing hormone. As a result, the production of follicle-stimulating hormone will be inhibited and testosterone levels will decrease.

What are the possible blood types of a baby with a mom who is heterozygous for blood type A and a dad with type O?
Answer:
A & O group
Explanation:
Dad will be having io io allele and mom will be having ia io
The possible blood types for the baby are either A or O, with equal likelihood of 50% for each.
What is blood type?A classification system called blood type explains whether or not specific antigens are present on the surface of red blood cells. Each of the four major blood types—A, B, AB, and O—has distinct antigen markers.
A and O are the two possible blood types for a child whose mother is heterozygous for blood type A (genotype AO) and whose father has type O (genotype OO).
A baby has a 50% chance of acquiring the A allele from the mother and a 50% chance of inheriting the O allele from the father because each parent gives one of their two blood type genes to their offspring.
Baby with blood type A inherits the A allele from the mother and the O allele from the father (genotype AO).
The child will have blood type O if both parents carry the O allele (genotype OO).
Therefore, the possible blood types for the baby are either A or O, with equal likelihood of 50% for each.

A cell moves particles from a region of lesser concentration to a region of greater concentration by Facilitated Diffusion.
Facilitated Diffusion in the cell body is the passive movement of particles across a plasma membrane from a region of higher concentration to a region of lower concentration

HELP!! Which of the following is NOT true of protein structure?
A: Proteins' secondary structure is dictated by peptide bonds.
B: Proteins' tertiary structure is dictated by R group bonds.
C: Proteins have quaternary structure when they are arranged together.
The statement that is not true related to the protein structure is option b. Proteins' tertiary structure is dictated by R group bonds.
What is protein structure?It is classified as the three dimensional shape of the protein.
In the tertiary structure it does contain the single polypeptide chain that we called as the backbone or there more than one protein secondary structures
Also, it should not be dictated by R group bonds.
Therefore, we can conclude that the option b is correct.

Explanation:
Most species of E. Coli are harmless or even helpful forms of bacteria that are found in the human intestine. E. Coli can aid humans in digestion and provide protection from other invading bacteria, but if the bacteria move to the human excretory system, they can replace other naturally occurring bacteria (Lactobaccilli). This can lead to bladder and kidney infections. Researchers found that by replenishing the excretory system with the naturally occurring bacteria, the infection caused by E. Coli is cured. Based on the research, what inference can researchers claim about the effect of bacteria?
Answer:
The inference is that bacteria can be pathogenic or characteristic of the commensal microbiota of different organs.
Explanation:
The human coexists with commensal micro-flora or commensal biota that are in balance and protect it from other pathogenic microorganisms, that is why we constantly live with a group of bacteria that do not generate pathological conditions in our body and even promote the stimulation of the immune response. .
When this balance is broken, pathogenic or opportunistic microorganisms invade, this is how they proliferate and generate infectious diseases that threaten the balance or state of human health.

Widow's peak is a dominant trait (W). Tongue-rolling is a dominant trait (T). Two people who are heterozygous for both traits (widow's peak, tong-roller) get married and have children. Complete the Punnett square to show the parents the probabilities for each child, then answer the question that follows.
What is the probability that the parents will have a child without a widow's peak and unable to roll his tongue?
Group of answer choices
3/16
9/16
0/16
1/16
Answer:
The correct answers are -
A. 1) WWTt 2) WWTt 3)WwTt 4)wwTT
B. 1/16
Explanation:
We know that each gene have minimum two alleles or forms of the gene one is dominant and the other is recessive. So, it is given that W is dominant trait that represents widow's peak so the recessive allele would be w, similarly for the tongue-rolling trait dominant is T n recessive would be t.
So the dihybrid cross of heterozygous parents for both is shown in the punnet square given which lack few possibilities that can easily be carried out by the gametes mention there that are
1. WWTt by WT and Wt gamets
2. WWTt by WT and Wt
3)WwTt by Wt and wT
4)wwTT by wT and wT
And the possibility of a child without a widow's peak and unable to roll his tongue would be possible only if the alleles are recessive for the both trait which is one out of 16 in punnet square thus the possibility would be - 1/16
