<h2>Ultraviolet (UV) Light</h2>

Explanation:

  • <em>Ultraviolet germicidal irradiation (UVGI)</em> is a purification technique that  inactivate microorganisms and the short wavelength ultraviolet (UV-C) light to execute by destroying nucleic acids and upsetting their DNA, leaving them incapable to vital cellular functions.
  • <em>Ultraviolet (UV) light kills cells damaging their DNA</em>
  • <em>The subsequent thymine dimer is very stable,</em> however fix of this sort of DNA harm for the most part by extracting or expelling the two bases and filling in the holes with new nucleotides is fairly efficient.
  • UV light applies its mutagenic impact by energizing <em>electrons in atoms</em>
  • <em>The excitation of electrons in DNA atoms regularly brings about the development of extra bonds between contiguous pyrimidines (explicitly thymine) in DNA</em>

Your friend is a pioneer in ES cell research. In her research, she uses an ES cell line that originated from an inbred strain of
Nezavi [6.7K]

Answer:

Explanation:

a)Organ transplantation requires that the donor organism and recipient be genetically close so that the graft or transplant will not be attacked by the immune system of the recipient leading to rejection and damage. Squeaky is likely to be made up of a different genetic configuration compared to laboratory inbred FG426 mouse

b) ips (induced pluripotent stem cell) on the other hand can benefit squeaky since the cells are somatic cells such as B cells, Keratinocytes, neuronal progenitors cells, kidney and muscles gotten from the donor that are reprogrammed by reactivating silent genes through fusing of another different cell such as ES (embryonic stem cell) and introduction of some transcriptional factors such oct4, sox2,kf4, and k-myc leading to transcriptional activity and DNA methylation.  This induced pluripotent stem cells can be grown into organ that can be transplanted to the recipient who was initially the donor of the reprogrammed somatic cells. Because it is from the host, the transplanted organ is not likely to trigger immune response compare to those grown from ES from other bred.

Carbon dioxide and oxygen enter and exit a leaf by diffusion. which structure(s) on a leaf allow(s) this process to happen?
Montano1993 [528]
The stomata and their guard cells allows this happen.

Stomata is like a hole or gap on a leaf, most of them are present in a bottom side of the leaf, since waxy cuticle is not present over there. And 2 guard cells make up a stomata.

Guard cells are able to control the size of the stomata, depending on the situation. For example, the guard cells close up during day time because a lot of sunlight may cause more water loss.

In conclusion, guard cells and the stomata are the main structures that allow carbon dioxide and oxygen (water too) diffuse in and out of leaves.
