Explanation:
Tall, perennial grasses and herds of grazing herbivores are inhabitants of tropical and temperate biomes and not desert biomes.
Deserts do not support the growth of perennial grasses and a sustained herd population.
- A desert is an arid landscape with very little to no rainfall through the years.
- Plants needs water to manufacture their food and live.
- Since this condition is absent, they cannot thrive in such biomes.
- Grazing herbivores needs a lot of grasses to satisfy their foraging and ruminant nature.
- Since grasses are lacking, they cannot survive.

Answer:
Hi, there the answer is D because Mitosis involves the process of growth and repair .
Explanation:
Answer:
The plasmid must express a gene for ampicillin resistance (the protein product of the <em>bla</em> gene codes for beta-lactamase, the protein that breaks down ampicillin). The colonies on the ampicillin plate are antibiotic resistant. This means that they have taken up the transformed plasmids expressing both the <em>bla</em> gene and the GFP gene.
Explanation:
The transformation involved the genetic modification of a plasmid to incorporate the gene encoding the green fluorescent protein (GFP) from jelly fish. GFP makes cells glow under UV light.
In genetic engineering, scientists use antibiotic resistance as markers to indicate cells that have been transformed. By incorporating an antibiotic resistance gene such as <em>bla</em> into the vector (plasmid) and then growing the cells in antibiotic media, scientists determine which colonies have taken up the plasmid. Therefore, if the cells survive, this means that they contain the plasmid with antibiotic resistance gene as well as the GFP gene.
It is possible to disrupt the plasma membrane by using enzymes and/or detergent agents.
<h3>What is the plasma membrane?</h3>
The plasma membrane is a lipid bilayer that is mainly composed of phospholipids and cholesterol.
In laboratory conditions, it is possible to disrupt this lipid bilayer by using detergent and proteins (enzymes) that break the bonds binding phospholipids.
For example, enzymes can break down the double bonds that bind fatty acids in the lipid bilayer.
In conclusion, the plasma membrane can be break down by applying enzymes and detergents.
