Why is it important that the ozone layer in the upper stratosphere is replenished?

Biology
1 answer:
harina [27]3 years ago
6 0

The ozone layer absorbs most of the ultraviolet light from the sun. UV light is harmful to organisms because it can damage the genetic material in living cells. By shielding the Earth's surface from most of the sub's ultraviolet light, the ozone in the stratosphere acts like a sunscreen for the Earth's inhabitants.

Compare the structure of a dicoty and monocot plant?​
Svetach [21]

Answer:

<em>hope</em><em> </em><em>my</em><em> </em><em>answer</em><em> </em><em>helps</em><em> </em><em>mark</em><em> </em><em>me</em><em> </em><em>brianliest</em>

Explanation:

Monocots differ from dicots in four distinct structural features: leaves, stems, roots and flowers. ... Whereas monocots have one cotyledon (vein), dicots have two. This small difference at the very start of the plant's life cycle leads each plant to develop vast differences.

Proteins have all of the following properties except enzymes
nevsk [136]

Proteins have all of the properties except genetic material.

<h3>What do you mean by Proteins?</h3>

Proteins may be defined as naturally emerging, extremely complicated substances that consist of amino acid residues joined by peptide bonds.

Proteins have the following properties:

  • They are enzymes.
  • Work as signaling molecules in numerous signaling.
  • They are involved in the transport of materials.
  • They provide a structural arrangement to the cells.

Therefore, proteins have all of the properties except genetic material.

Suppose there is a protein "A" which binds to a DNA sequence and increases transcription of the gene CBC23. In the presence of m
fenix001 [56]

Answer:

A = Activator

B = Effector

Explanation:

An activator is a protein which typically binds to a short (50–1500 bp) region of DNA which might be located either upstream (mainly) or downstream of a gene so as to cause increased transcription. This particular region of DNA is known as enhancer and activator is also  known as transcription factor. Activator is a trans-acting factor which binds to the cis-acting factor which is enhancer so as to enhance transcriptional expression.

But another protein named as effector may restrict activator from binding to the enhancer leading to a decrease in transcriptional expression by binding to the activator allosterically. Allosteric binding of effector to the activator causes conformational change in activator so it can no longer bind the enhancer.
