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.

Answer:
No, it is not good for the environment.
Explanation:
It has made the biggest change in our economy and many people are buying a large stock of items to keep in their homes because they think the stores close for a certain week or day because of the virus, so just in case for them, they have to quickly run into the store and get all of the items they could find so they can last while they are at their homes. And there are people that have the virus and if they touch something like an object or a person, the bacteria can stick onto the object or person, and when someone touches the object and does not know about the virus being there, the person can get really sick and probably have initial flu-like symptoms, such as fever, coughing, breathing difficulties, fatigue, and myalgia. It is best that you are washing your hands and that you stay away from sick individuals. And that you do not go out too often and stay safe at your house.

Explanation:
This question involves two distinct genes; one coding for seed shape and the other for seed colour. The allele for you seeds (R) is dominant over the allele for wrinkled seeds (r) in the first gene while the allele for yellow seeds (Y) is dominant over allele for green seeds (y).
In a cross involving RRYY (homozygous dominant for both traits) and RrYy (heterozygous for both genes), the following allelic combinations of gametes will be produced:
RRYY- RY, RY, RY, RY
RrYy- RY, Ry, rY, ry
Using these gametes in a punnet square (see attached image), 16 possible offsprings will be produced. The genotypes of the offsprings in the ratio 1:1:1:1 will be:
RRYY (4)
RRYy (4)
RrYY (4)
RrYy (4)
According to the question, offspring that have wrinkled seeds and yellow seed color will have genotype: rrYY or rrYy.
This genotype is not one of those that will be produced by the cross between a RRYY and RrYy parent. Hence, the probability of having an offspring with wrinkled seeds and yellow seed color is 0%
