Outline the effect of CFCs on the ozone layer.

Biology
1 answer:
Serhud [2]3 years ago
8 0
The ozone layer is a stratospheric region composed of Ozone (Triatomic Oxygen) 

CFC´s (Chlorofluorcarbons) are broken down by ultraviolet radioation to release chloride ions wich react with ozone breaking it down into oxygen.

One chlorine atom can destroy 100.000 ozone molecules - smallamounts of CFC can break down large amounts of ozone.

The thinning of the ozone layer by CFCs reduces the absorption of UV light in the stratosphere

Blood does not enter or leave the ventricles during the period called
babymother [125]
That would be D. Isovolumic contraction

As the name states during ISOvolumic contraction the volume of the ventricles doesn’t change and stays the same so no blood enters or leaves the ventricles. The thing that changes is the pressure of the ventricles that increases.

I can explain the process more if u want in the comments:)

Question 4
Juliette [100K]

Answer:

In eukaryotes, thousands of chemical reactions are able to take place in  separate compartments called organelles.

Explanation:

Organelles are specific cellular structures that are the means of compartmentalizing the various functions that occur within cells.

Examples of organelles and their functions are:

- <u>Nucleus</u>: contains DNA and in it occur the replication of this molecule and its transcription into RNA.

- <u>Rough endoplasmic reticulum</u>: protein synthesis and conjugation of these molecules occurs.

- <u>Mitochondrion</u>: houses all oxidative phosphorylation reactions and the electron transport chain for ATP synthesis to occur.

The organelles are then the structures that allow the development of the multiple functions that a cell has.

The other options are not correct because:

  • <em><u>Bacteria</u></em><em> is a prokaryotic organism. </em>
  • <em><u>Prokaryote</u></em><em> refers to simple organisms that lack organelles. </em>
  • <em><u>Proteins</u></em><em> are biomolecules that allow the structure and function of living beings.</em>
