The statement is - True.

The solvent do contains chlorofluorocarbons (CFC) and hydrochlorofluorocarbons (HCFC) which evaporate and enter the atmosphere. Because they are very light, the CFC and HCFC manage to get very high into the atmosphere, reaching the ozone layer in the stratosphere. They are actually the two substances that are the most damaging to ozone layer, as once they get in touch with it, they break down its structure, thus creating the ozone holes.

The ozone is crucial for the survival of the living organisms on the Earth as it is the layer that manages to stop most of the ultraviolet rays form the Sun to reach the surface. Because of that, these two substances have to be replaced quickly as the ozone layer is becoming more and more damaged, and that can eventually lead to a tragedy

Witch of the following accord along coasts during the day
mina [271]

The following one that accords along coasts during the day is sea breezes. These happen when the cold air from the ocean is gushed to the land around and and because water is slow to absorb heat, it causes breezes we call sea breezes.


Answer: Sea breezes

Note: Witch how you spelled it means a witch that works with magic. The "which" you were trying to use is spelled which. Also next time it helps if you put out the options too. I saw this was your first question so it's all right. I hope this was helpful to you! (before you use your points to ask a question, search brainly or the internet for it and you might find it and you don't have to use your points ; ) )

Answer:

Problems with transfection efficiency or absence of essential mRNA modifications (capping and poly-A tail)

Explanation:

Translation is the process of protein synthesis from RNA in which the genetic information encoded in a messenger RNA (mRNA) molecule is translated into a protein sequence composed of amino acids. Translation has three steps: initiation, elongation, and termination. During translation, different elements are required to initiate, continue and complete the process, which include essential molecules such as amino acids, mRNA, tRNAs, ribosomes, energy-carrying molecules (i.e., ATP, GTP), initiation factors (i.e., eIF1A, eIF3, etc) and elongation factors (eEF-2, EIF5A). For example, humans can't synthesize nine essential amino acids (i.e., threonine, tryptophan, phenylalanine, valine, methionine, leucine, histidine, isoleucine, lysine), thereby it is imperative to include these amino acids to synthesize proteins composed of them. On the other hand, it is also fundamental to take into account that the efficiency of transfection of the molecules required during translation, as well as the absence of modifications in the mature mRNA sequence, may alter the process in vitro.

Identify Causes: What are some factors that might cause changes in the population of grasshoppers?
zubka84 [21]

Answer:

Empty calories may be grasshoppers' downfall.

Explanation:

Many insect populations are declining, and a provocative new hypothesis suggests one problem is that rising levels of atmospheric carbon dioxide (CO2) are making plants less nutritious. That could spell trouble not just for insects, but for plant eaters of all sizes.

Answer:

Hydrogen disulfide

Explanation:

Hydrogen disulfide , which is responsible for the rotten-egg scent, is toxic rather than simply smelly, if inhaled at concentrations above 700 parts per million.

It can be present at very low concentrations well below those considered to induce health effects. The scent of sulfide hydrogen does not affect your well-being.
