Which of the following describes how both of these cellular division processes maintain genetic continuity?
А.Both processes involve the replication and division of identical genetic material.
B. Both processes creates cells with half the genetic material of the parent cells.
C. Both process involve the recombination and division of new genetic material.
D. Both processes create cells with twice the genetic material of the parent cells.

Answers

Answer: Both processes involve the replication and division of identical genetic material

Explanation:

During S phase interphase DNA is replicated and it is replicated as an exact copy

When a single cell divides into two cells through mitosis, genetic continuity occurs. One cell divides into two during the process of mitosis, and each of the two progeny cells has the same amount of DNA as the parent cell.

What is genetic continuity?The fact that when a cell divides, the resulting two daughter cells have the same number and type of genes as the original cell is referred to as genetic continuity. It also describes how when two sexually reproducing organisms mate, their offspring have the same number of genes as the parents. Nuclear division results in daughter cells with identical sets of chromosomes. Mitosis ensures the genetic continuity of the ancestral cells in the body's daughter cells. It consists of one fully equational division followed by a DNA synthetic phase. Because it creates a perfect copy of DNA for new cells, DNA replication helps to maintain species genetic continuity.

Jonathan designed an experiment to plant lima bean seeds. His variable was to change what kind of light each plant received. He
used a different kind of light with each plant. He hypothesized that the plant grown under the plant light would have the greatest
amount of growth. Did the data support the hypothesis? Explain.

Answers

Answer:

Yes, it was.

Explanation:

The data did support the hypothesis because the data given was generalized on the change of light each plant received. The hypothesis was that the plant light would have the greatest amount of growth. The data was the different light types and the hypothesis was which one he inferred would work best.

Which of the following correctly matches a catastrophic weather event with its effects on an ecosystem?

Answers

Answer:

I think the answer would be C.

Explanation:

It's the one that makes sense.

Buildings can be demolished, which can result in the release of various harmful substances into rivers, lakes, bays, and the ocean, harming marine life. These substances include paint, pesticides, and gasoline. Thus, option C is correct.

What are the effect of catastrophic weather on ecosystem?

Droughts that are more frequent and extreme, storms, heat waves, rising sea levels, melting glaciers, and warmer oceans can all directly injure animals, destroy the habitats they rely on for survival.

And have a disastrous impact on people's way of life and communities. As climate change worsens, dangerous weather occurrences occur more frequently or with greater severity.

When drainage systems are destroyed by floods, raw sewage leaks into bodies of water.

Therefore, a thunderstorm lightning can start a forest fire.

My terrarium has a geosphere (my plant and soil) , biosphere (oxygen) , hydrosphere (the water I used to feed my plant) , and finally, my atmosphere (an LED plant light) .
These are the things my plant needs to survive.

Answers

Answer:

Remove the 'my' in the sentences, basically if you want it to be grammatically correct rewrite like this:

The terrarium that was built has a geosphere, the plants and soil, an atmosphere, the oxygen that allows the life to grow, a hydrosphere, the water the plant uses, and finally a source of light. Overall this makes a biosphere which allows the plant to survive and thrive.

Also you mixed up biosphere with the atmosphere.
