A chromosome has an inversion.which describes a pericentric inversion?

Answers

Answer 1
Answer: Deletion of genes around the centromere is considered a pericentric inversion. The Pericentric inversions include the centromere and there is a break point in each arm. Deletions and duplications occur during crossing over during the inversion which results in recombination in two loops.
Answer 2
Answer: Deletion of Genes is the answer :) hoped I helped I took the test it came out correct.

True!
Most energy enters ecosystems in the form of sunlight. Plants convert solar energy to chemical energy in the form of sugar. This energy will leave the ecosystem as heat energy. 

Answer:

The answer is sunlight

Explanation:

"Over the years, the forest cover in a particular ecosystem was reduced from about 50% to 20%. What would be the MOST LIKELY effect of this?A) The loss of moisture from the soil would be reduced.
Eliminate
B) Herbivores would be forced to change into carnivores.
C) The flow of energy in the ecosystem would be affected.
D) The exchange of carbon dioxide in the ecosystem would increase"

Answers

The correct answer is option C

If the forest cover in an ecosystem is reduced from 50% to 20%. The most likely effect is that the flow of energy in the ecosystem would be affected.The forest means the green plants that are also known as the producers of the ecosystem and they transfer energy to the consumers and the ecological balance is maintained. If there will be less producers then the flow of energy in the ecosystem will be affected.
