Answer:
option A is correct
Explanation:
Explain why the ratio of motor neurons to muscle fibers is greater in muscles that control eye movement than in postural muscles of the leg.
Answer:
The muscles of the eye cover a greater number and in turn carry out greater fine motor skills.
Explanation:
Alpha motor neurons are neurons that invent the skeletal muscle, that is, striated, so that through the motor plate that is the unit that unites them, an action potential is transmitted that contracts the sarcomeros of the elastic fibers and the z lines. come closer, each eye movement is much more precise than the locomotion of the lower limb, which carries greater innervation in each muscle bundle due to the specificity of the movement, this is how more alpha motor neurons are required to mobilize the eye than a leg.
The specificity and preciseness of eye movement control justifies why the ratio of motor neurons to muscle fibers is greater for muscles controlling eye movement than those in the postural muscles of our leg.
The function the eyes performs requires more precise locomotion control than the movement of the limbs require.
For an eye movement to be made, an action potential must be transmitted which makes the sarcomeres of the elastic fibers and z-lines to unit thereby producing movement of the eye. This movement are usually done with almost perfect preciseness.
This is why there are more alpha motor neurons that control eye movement than we have in postural muscles of the leg.
In summary, the specificity and preciseness of eye movement control justifies why the ratio of motor neurons to muscle fibers is greater for muscles controlling eye movement than those in the postural muscles of our leg.

Explanation:
Increased numbers of CAG repeats in the exon of a gene is associated with certain diseases. In a specific gene, the existing CAG codons are in the 'zero' reading frame, in- frame with the AUG initiation codon. The effect of increased numbers of CAG repeats on the encoded protein is:___________. a. to silence of the gene to generate a truncated protein b. to generate a protein with a run of consecutive glutamines c. to generate a frameshifted protein product d. none of the above
Answer:
The correct answer is - option b. to generate a protein with a run of consecutive glutamines.
Explanation:
The initiation code AUG is the code for methionine and as well as the initiation code for the particular protein or peptide chain. In this protein, there is a repeat of CAG is increased with the initiation code so, even though they are in zero reading frame they code for their amino acid which is glutamine.
So. an increased number of CAG repeats will result in a protein with the a run of consecutive glutamines.
Which part of photosynthesis is represented by the diagram to the right
Answer:
Light-dependent reactions
Explanation:
Photosynthesis occurs in two stages: light-dependent reactions and light independent-reactions. This last stage is often called Calvin cycle.
The diagram shows reactions occurred in the thylakoid membranes which are located inside the chloroplasts. Therefore, we can identify that these reactions are the light-dependent reactions. During this part of photosynthesis, the energy from the sunlight is absorbed by a pigment called chlorophyl (Chl). Then, it is sequentially coverted into chemical energy stored in the form of molecules: NADPH (nitotinamide adenine dinucleotide phosphate) and ATP (adenosine triphosphate).
A group of people have white blood cell (WBC) counts that are from 4,500 to 10,000 WBC/ml. All cell count values in that range are equally abundant in the population. What is the mean WBC count in the population?
Answer:
7250 WBC/ml
Explanation:
The mean of any value is the average of a certain amount of given values. When this is taken into cognizance, to get the mean White Blood Cell count of the population, given two ranges, is to add and divide both together. This gives us
10,000 + 4,500 = 14,500 WBC/ml
The mean then is
14,500 / 2 = 7250 WBC/ml
Therefore, the mean White Blood Cell count in the population is 7250 WBC/ml

Yeast cells, plant cells, and mammal cells all share many similarities in cell signaling. This provides evidence that:________
a. cell-signaling mechanisms are only found in organisms that use methods of sexual reproduction
b. intercellular communication evolved as a way for multicellular organisms to coordinate cell functions
c. eukaryotic cells use signal transduction pathways while prokaryotic cells use a more primitive form of signaling
d. signal transduction pathways appeared in cells before the evolution of multicellular organisms
Answer:
D
Explanation:
Yeast cells, plant cells, and mammal cells all share many similarities in cell signaling. This provides evidence that signal transduction pathways appeared in cells before the evolution of multicellular organisms. Thus, the correct option for this question is D.
What is cell signaling?Cell signaling may be defined as a process through which a cell of an organism may respond to substances outside the cell through signaling molecules found on the surface of and inside the cell.
This biological process of cell signaling is ultimately required in order to accomplish all sorts of metabolic activities that are essential for the survival of living organisms, no matter whether they are prokaryotic or eukaryotic, unicellular or multicellular.
Therefore, the correct option for this question is D.

B-heterotrophs
C-sexual reproducers
D-asexual reproducers
Answer: B heterotrophs

Identify all statements that accurately describe the structure of the pyruvate dehydrogenase (PDH) complex.A. A regulatory kinase and phosphatase are part of the mammalian PDH complex. B. Several copies each fo E1 and E3 surround E2. C. E2 contains three domains. D. The complex contains multiplex is made up of several copies of E1.
Answer: Options A, B ,C and E are correct
Explanation:
The structure of pyruvate dehydrogenase complex comprises if three enzymes E1, E2 and E3 which convert pyruvate to acetyl CoA. The three enzymes are have several copies.
Within the PDH complex, the E2 subunit forms the structural unit, contain three domains and are surrounded by E1 and E3. The E 2 accepts acetyl groups from E1 and transmit the group to coenzyme A. The decarboxylation of pyruvate and its conversion to acetyl-CoA by the PDH complex comes first before glucose carbon enter into the tricarboxylic acid (TCA) cycle. This process is important to the aerobic oxidation of glucose .

Why do aquatic organisms have to constantly deal with osmosis
Answer:
Because salt is an agent that attracts and draws out water, the surrounding salt water draws water from inside the fish so they must constantly drink water to replace the lost water in their system. The process of water being drawn out of the body by the surrounding water of higher salt levels is known as osmosis.
