Answer:

C: Levels of Specific Hormones

Explanation:

Process of Elimination. Enzymes have nothing to do with female reproduction, ATP is also irrelevant to the subject. And heart rate does not affect it either.

Set of answers are:

A) protein subunits associated with gap junctions. <u>Conexin</u>

B) a type of adhesive junction connecting an epithelial cell to the basal lamina.<u> Hemidesmosome</u>

C) collection of fibrous intracellular attachment proteins.<u> Plaque</u>

D) create a permeability barrier. T<u>ight junctions</u>

H) intermediate filaments associated with plaques. <u>Tonofilaments</u>

I) collection of adherens junctions particularly associated with epithelial cells.

J) type of adhesive junction containing actin microfilaments. <u>Adherens junctions</u>

L) point of cytoplasmic contact between two cells. <u>Gap junction</u>

M) anchors cytoskeleton of one cell with that of a neighboring cell. <u>Adhesive junction</u>

<u />

Explanation:

<u>Connexin:</u> is a transmembrane protein that forms the gap junctions, they are also called gap junctions proteins.

<u>Hemidesmosome junctions:</u> these types of junctions are in the epidermis, specifically between the epithelial cells and the basal lamina of the epidermis.

<u>Plaque:</u> they are part of the adherens junctions, they are fibrous proteins that are attached to certain points of the extracellular matrix.

<u>Tight junctions</u><u>:</u> are junctions between two epithelia, they are very restrictive and do not allow the passage of soluble molecules creating a permeability barrier.

<u>Desmosomes</u>: are very strong cell to cell junctions on the lateral sides of plasma membranes. They are in tissues that are under mechanical stress, such as the cardiac muscle.

<u> Connexons:</u> is a pore made of six connexin proteins in a gap junction. Connexons are the ones that connect two cells in gap junctions.

<u>Focal adhesions:</u> They connect the extracellular matrix with the cell, regulatory signs and mechanical force is transmitted through them.

<u>Tonofilaments:</u> tonofilaments are the ones that are associated with a plaque in adherens junctions, they are in epithelial tissues.

<u>Adherens junctions:</u> are cell to cell junctions where the cytoplasmatic face is connected to the actin cytoskeleton. They appear as spots forming the plaque or as zonula adherens, which are actin bands around the cell.

<u>Cell junctions </u>are protein complexes that connect two cells that are next to each other or a cell with the extracellular matrix. They have a lot of functions, such as pas information from cell to cell, or the exterior, form a barrier, synchronize cells, etc.

<u>Gap junctions:</u> are connections between the cytoplasm of two cells, molecules and, ions pass directly from one cell to the other.

The human MN blood type is determined by two codominant alleles, L(M) and L(N). The frequency of L(M) in Eskimos on a small Arct
tatiyna

Answer:

(a) Frequency of M = 0.64

    Frequency of N = 0.04

    Frequency of MN= 0.32

(b)  Expected frequencies of M = 0.648

     Expected frequencies of MN = 0.304

     Expected frequencies of N =  0.048

Explanation:

(a) If random mating takes place in the population, then  the expected frequencies are

f(L(M)) = p = 0.8

F(L(N)) = q

q= 1 - p

= 1 - 0.8

= 0.2

Frequency of M = p^2 = ( 0.8)^2 = 0.64

Frequency of N = q^2 = (1-p)^2 = (1 - 0.8)^2 = (0.2)^2 = 0.04

Frequency of MN = 2pq = 2 * 0.8 * 0.2 = 0.32

(b)

F = inbreeding coefficient = 0.05

f(L(M)L(M)) = p^2 + Fpq = (0.8)^2 + 0.05 * 0.8 * 0.2 = 0.648

f(L(M)L(N)) = 2 pq - 2Fpq = 2 * 0.8 * 0.2 - ( 2 * 0.05 * 0.8 * 0.2) = 0.304

f(L(N)L(N)) = q^2 + Fpq = (0.2)^2 + ( 0.05 * 0.8 * 0.2) = 0.048

Name one enzyme of glycolysis that catalyzes an essentially irreversible step: __________
Alenkinab [10]

Answer:

Phosphofructokinase-1

Explanation:

Phosphofructokinase-1 catalyzes the phosphorylation of fructose 6-phosphate into fructose 1,6-bisphosphate. The reaction is exergonic with a large negative free energy change to make it essentially irreversible.  

Phosphofructokinase-1 is an allosteric enzyme with regulatory sites. Higher ATP concentration serves to inhibit the phosphofructokinase-1 by binding to the allosteric site of the enzyme and thereby reducing its affinity for the substrate (fructose 6 phosphate).

Mutations in the nucleic acid sequence of a gene can sometimes direct the substitution of one amino acid for another in the enco
jonny [76]

Mutations in the nucleic acid sequence of the gene that can be sometimes direct the substitution of one amino acid for another in the encoded protein. Arginine and methionine amino acid are the substitution that would be most likely to severely disrupt the normal structure of the protein

A genetic mutation is the change to a gene's DNA sequence that produce something different. It also creates a permanent change to that gene's DNA sequence. Genetic variations are the important for the humans to evolve, which is the process of change over the generations. A sporadic genetic mutation may occurs in one person.

A mutation is a change in the DNA sequence of the organism. Mutations can result from the errors in the DNA replication during the cell division, exposure to the mutagens or the viral infection.
