<span>The female frog's reproductive system is consist of a pair of ovaries and a pair of oviducts. The ovaries are attached to the kidneys. The kidneys carry countless ova which are released to outside through the oviducts. </span><span>In the breeding season, the male and the female frogs enter into a temporary union called amplexus. The male holds the female, presses her trunk and thereby forces the female to release the eggs, the male frog then releases the sperms immediately to bring about exterior fertilization.</span>

In response to viral infection, the immune systems of mice typically produce antibodies that destroy the virus by binding to pro

VMariaS [17]

Answer:

(D) There are mice that are unable to form antibodies in response to herpes infections, and these mice survive these infections without ever developing keratitis

Explanation:

Option A: irrelevant, we do not care about other viruses.

Option B: There is no relation with keratitis.

Option C: This could mean that antibodies are not responsible for keratitis, so it does not support the hypothesis.

Option D (correcto answer): A lack of antibodies equals a lack of keratitis; this supports the argument that antibodies are involved in the development of keratitis.

Option E: misleading and does not support the hypothesis.

Nutka1998 [239]

Answer: Telomeres, Helicases, Okazaki, DNA polymerase, Topoisomerase

Explanation:

1. Telomeres these are set of repetitive nucleotide sequence found at the end of a linear chromosomes they help preventing the DNA chromosome frrom sticking to other DNA chromosomes.

2. Helicases are proteins that uses energy (ATP) to unwind DNA strands during replication.

3. Okazaki fragments the small DNA nucleotide sequence synthesized separately on the lagging strand.

4. DNA polymerase are enzymes that catalyzes the addition of deoxyribonucleotides to DNA during replication.

5. Topoisomerase are enzymes that prevent single stranded DNA from supercoil, rumple and winding back during replication.

this image shows the location of convection at different latitudes around the globe. explain what causes convection to take plac

Bas_tet [7]

Forced convection may happen by natural means, such as when the heat of a fire causes expansion of air and bulk air flow by this means. The shock wave that transfers heat and mass out of explosions is also a type of forced convection.

Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth.

Mantle convection is the slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface.This subjected material sinks through the Earth's interior.
