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.

Answer:
Explanation:
The amount of biomass that is produced in an area during a given time is referred to as primary production/productivity.
<h3>What is biomass?</h3>
- Renewable organic material obtained from plant and animal sources if referred to as biomass.
- Primary productivity is the production of organic compounds through the process of photosynthesis, with the help of solar energy.
- Primary productivity is measured as biomass produced per unit area over a give time period
- It is usually expressed either in weight or energy.
- There are two ways to express primary productivity:
a) Gross Primary Productivity(GPP): Takes into account the total energy produced in the ecosystem.
b) Net primary Productivity(NPP): Takes into account, solely the energy used by the producer for respiration.

One advantage of asexual reproduction is that animals can <span>increase their numbers rapidly. The other options in the question are incorrect and so avoided. The correct option among all the options that are given in the question is the first option or option "A". I hope the answer has helped you.</span>
