Answer and Explanation:

Humans are one of the most powerful biotic factors. Human activities have had great influence on the distribution of other organisms. The use of aerosols and industrial chemicals like chlorofluorocarbons which are residual and persistent can cause depletion of the ozone layer. This results in harmful radiations from the sun reaching the earth's surface.

Excessive production of CO2 by the industries and removal of vegetation like the trees results in the accumulation of CO2 in the lower atmosphere. This causes the greenhouse effect which results in global warming.

Radioactive emission from nuclear reactors, mine and radioactive wastes causes cancer, mutations and even death.

Answer:

just learned about this in ap bio haha

Explanation:

Wow, that's such a cool prokaryotic cell. It looks so delicious, I wonder if I can eat it.

"Hey, cell, can I eat you?"

"No, you cannot."

"Please? I would love to have your energy-making properties!"

"How would I benefit from this? It seems like you're being parasitic."

"I would help you, by giving you protection and a safe home. You would give me energy. It seems more like an endosymbiotic relationship to me!"

"Fine, you can ingest me."

I'm so glad they let me eat them, they were so yummy. I can even create energy now, and I have a powerhouse inside me! This is so cool, maybe I should eat that other cell with photosynthetic properties.

SORRY IF THIS IS TERRIBLE I REALLY TRIED

Answer;
$A7
If cell reference $A5 in a formula is copied and pasted over two columns and down two rows from its original cell, the cell reference in the new cell becomes $A7.

Explanation;
Absolute cell reference is a cell address that contains a dollar sign, $, in the row or column coordinate, or both. such that when you enter a cell reference in a formula, the Excel assumes it is a relative reference unless you change it to an absolute reference.

mariarad [96]

Answer:

The gray matter in the spinal cord is located in the grey column , and its shape resembles a letter H, or a butterfly. The cell bodies of somatic motor neurons are primarily housed in the ventral or anterior horns, which innervate skeletal muscle.

Explanation:

The grey matter is a component of the central nervous system that contains neuronal and glial cells and it can be found in the brain, brainstem and spinal cord, in this last one, is found in the grey column, a mass of grey matter shaped in H form.

In this column the grey matter is divided into four columns (as you can see in the image I added):

The dorsal or posterior horn: contains somatosensorial neurons
The ventral or anterior horn: contains somatic efferent motor neurons (they exit the spinal cord to innervate skeletal muscle)
The intermediate column: contains neurons to innervate visceral organs
The lateral horn: same as the intermediate column

I hope you find this information useful and interesting! Good luck!

Ftsz is a bacterial cytoskeletal protein that forms a contractile ring involved in binary fission. its function is analogous to

Gennadij [26K]

The answer to the question is the cleavage furrow of eukaryotic animal cells. Analogous structures are various structures in different species having the same function but evolved separately, thus do not share a common ancestor. FtsZ assembles into a ring at the future site of the septum of bacterial division, it is a prokaryotic homologue to the eukaryotic protein tubulin.
