Answer: Here is the option.

A. The inducer combines with the repressor and causes the repressor to bind to DNA

B. The inducer combines with the repressor and causes the repressor to dissociate DNA

C. The inducer combines with the substrate and blocks induction

D. The inducer combines with the substrate and activates induction

E. The inducer does not combine with repressor but functions as a chaperone molecule for the enzyme-substrate complex

The correct option is C.

The inducer combines with the substrate and blocks induction

Explanation:

Enzymes inducers are drugs or enzymes that Induces or bring out the activity of enzymes been expressed.

This drug increases the metabolic activity of an enzyme either it binded to the enzymes or in a away cause an increase gene code of an enzyme to be expressed.

When an inducer is added to a medium containing an organism with metabolic pathway controller by a repressor it will combine with the repressor and block induction because an enzyme repressor regulate enzyme activity in a negative way by reducing it's synthesis rate.

✔ axial skeleton  = sternum

✔ axial skeleton  = skull

✔ appendicular skeleton = hips

✔ axial skeleton = ribs

✔ appendicular skeleton = shoulders

✔ appendicular skeleton  = arms and legs

Please answer 5&amp;6. Thank you.

Answer:

5. The correct answer would be an option A. ova

Note: I assume that all the samples are of human origin.

DNA (deoxyribonucleic acid) content of somatic cells of humans consists of 46 chromosomes or 23 pairs of chromosomes. Gametes (sperm or ova) are haploid cells produced by the process of meiosis and contain half the number of chromosomes found in parent cell. Hence, they contain 23 chromosomes.

6. The correct answer would be an option J.

Sperm formation or spermatogenesis is the process by which spermatozoa (haploid gamete) is produced from germ cell with the help of meiotic division.

Meiosis results in the formation of four haploid (n) cells from single diploid (2n) parent cell. Here, 2n is given as 8 so, n would be equal to 4.

Meiosis I results in the formation of two secondary spermatocyte cells (both haploid or 4 chromosomes in this case) from single primary spermatocyte (diploid or 8 chromosome in this case).

Both the secondary spermatocytes undergo meiosis II to produce 4 spermatids (each haploid or 4 chromosome in this case). Spermatids differentiate and mature into spermatozoa.

Fungi produce many compounds that humans are able to use medically. how can you account for these compounds?
levacccp [35]
None of those options are correct. 

Fungi produce,naturally, antibiotics that will kill or inhibit the growth of bacteria.
This is useful for them to limit competition in their natural environment but it's also useful for us because it will kill bacteria that cause us infections.

The only thing scientists had to do is isolate that antibiotic.

Some antibiotics that were developed from fungi: penicillin and cephalosporins.

In the marine mollusk, Aplysia, serotonin binds to a G-protein-coupled receptor and activates a Gs subunit. The resulting activa
dem82 [27]

The serotonin binds to a G-protein -coupled receptor and activates a G-subunit . This results in activation of PKA and closing of the potassium channels. This will subsequently decrease the influx of potassium ions into the cell, and lead to depolarization of the cell. This changes the membrane potential of the cell.

Aplysia are sea slugs which fall under the category of mollusks. Serotonin is a hormone which is responsible for the transfer of electrical signals from the brain to different parts. In this particular mollusk, serotonin was studied to find that it is an essential neurotransmitter that is responsible for the maintenance of synaptic plasticity in the neurons. Synaptic plasticity is the feature which is essential for the communication of neurons. This is the modification which occurs at the synapses during the transmission of synapses. Without this activity, the transmission of signals would be impossible.
