Recall that two hydrogen bonds bind A and T, but three hydrogen bonds bind G and C. Because the stability of DNA is affected by

Answer:

A molecule with 32 percent or more amount of Cytosine.

Explanation:

DNA is the genetic material of all the living organism but in few viruses, RNA can also acts as the genetic material. DNA contain nitrogenous bases ( adenine, guanine, thymine and cytosine), deoxyribose pentose sugar and the phosphate bond.

The triple bond is more stable than the double bond. Since, cytosine and guanine shows triple hydrogen bonding and shows more stability. The DNA molecule that contains more residues of guanine and cytosine is stable than the molecule containing adenine and thymine residues.

Thus, the answer is molecule with 32 percent or more amount of Cytosine.

Crossing over (exchange of genetic information between regions of non-sister chromatids in the tetrad) occurs in the prophase I stage of meiosis.

<h3>WHAT IS MEIOSIS?</h3>

Meiosis is the process whereby a single cell produces four daughter cells that are genetically different from one another.

Meiosis is able to ensure genetic diversity in the daughter cells due to a process called Crossing over.

Crossing over is the exchange of genetic material between the non-sister chromatids of homologous chromosomes. It occurs in the prophase I stage of meiosis.

Therefore, crossing over (exchange of genetic information between regions of non-sister chromatids in the tetrad) occurs in the prophase I stage of meiosis.

during the paleozoic and mesozoic eras plate movements were rapid. this caused many volcanoes to occur. how could this impact th
kompoz [17]

Explanation:

Many violent volcanoes spew a lot of pyroclasts and gases such as carbon dioxide and sulfur dioxide high into the atmosphere. The fine pyroclast would linger in the atmosphere for months and even years  blocking out the sun. This would cause vegetation to die out and decrease. Photosynthetic organisms re usual producers and the entry point of energy from the sun into ecosystems. Their death would mean the collapse of ecosystems.

Settling pyroclast would also blanket vegetation in thick layers hence also denying them access to sunlight. There would be a definite drastic decline in population and communities and ecosystems, and even extinction akin to the extinction even to the dinosaurs during the meteorite strike.

What part of the cell manufactures the ribosomal subunits
Lemur [1.5K]

When newly formed proteins leave the rough endoplasmic reticulum, they are transported to this organelle, where the proteins are sorted and packaged. Golgi apparatus. This part of the cell manufactures the ribosomal subunits.


Golgi apparatus


IF THAT DOESNT WORK THEN USE

Rough Endoplasmic Reticulum

What would happen if green plants were exposed to longer periods of sunlight
asambeis [7]

Answer:

Plants harvest energy from the sun with the help of chlorophyll and carotenoid, two photon-capturing molecules. But if the plants are exposed to too much sun, these molecules absorb more energy than they can handle and generate reactive species of oxygen that can destroy the plant.
