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.

The correct statement among the given answers is letter <u>d. an object in motion will remain in motion.</u>
<h2>
<u>WHY? </u></h2>
In reality, object that is in motion (like a ball) will remain in motion unless it's stopped by something (a wall or any force).
This is stated in the first law of motion by Sir Isaac Newton -- an object in motion will remain in motion unless an outside force acted upon the object.
The number of organsims at each levels, so there are more producer than herbivores, more herbivores than carnivores and so on...
Answer:
b) Bioremediation
Explanation:
The use of natural occuring or intentionally introduced micoorganisms to treat environmental pollutants is called as Bioremediation.
- Most of the bioremediation processes includes oxidation-reduction reaction.
- The natural degradation process of pollutants is improved by bioremediation.
- Green plant, Decomposers and their enzymes are used in bioremediation to imrprove the condition of the environment.
The Predator from an Ethiopian Highlands ecosystem is the Wolf. The Wolf is
regarded as a Carnivore and it gets its food from preys through Predation.
<h3>What is a Carnivore?</h3>
Carnivores refer to animals which feed on flesh . Carnivores are mainly
secondary or tertiary consumers in the ecosystem.
They prey on herbivores such as
The prey animal can be classified as Herbivores in terms of feeding
relationships. Herbivores feed on primary producers known as plants.
