Explanation:

An amino acid is an organic molecule that is made up of a basic amino group (−NH2), an acidic carboxyl group (−COOH), and an organic R group (or side chain) that is unique to each amino acid.

the common property of all protein is that they consists of long chain of a-amino acids

(alpha amino) acids .... In protein molecules the a-amino acids are linked to each other by peptide bonds between the amino group of one amino acid and the carbonxy group of its neighbours

Answer:

Mitosis is a necessary step in repairing cuts on the skin.

Explanation:

When the portion of tissue cracks, then there are cells wasted. So, mitosis will generate tones of fresh cells in periods to fill the break and secure the tissue greater again. This guarantees that the tissue is back to health and can perform accurately. It's like wound healing. A necessary goal of mitosis is to replenish dead or destroyed cells like skin cells that are continually being shed.

Answer:

I don';t see a chart

Explanation:

Around 3.8 billion years ago, near the conclusion of this phase known as the late heavy bombardment, life on Earth first emerged, hence option A is correct.

Even before the 3.5 billion years ago when the oldest fossils on Earth were discovered, just at the conclusion of the time of late intense bombardment, there is evidence of biological activity.

The 3.5 billion-year-old "stromatolites," which are hard structures created by bacteria, also provide evidence of their presence. Stromatolites are produced when microbe-made sticky mats catch and organize sediments into layers.

It has been discovered that trophozoites contain organic material from 3.5 billion years ago. 3.5 billion-year-old rocks have been found to contain microbial remnants, some of the planet's earliest evidence of life.

Therefore, 3.8 billion years ago, near the conclusion of this phase known as the late heavy bombardment, life on Earth first emerged, hence option A is correct.

Explanation:

The diagram or pyramid for the energy flow of an ecosystem represents the flow of energy from one end to the other end according to the food chain. It starts with the ultimate energy source the sun which is used by the producers to produce energy and this is the trophic level that carries the highest energy.

In the food chain, when primary consumers eat the producers they get 10% of the total energy producers carries due to loss of energy and 10% energy of primary consumer have transferred to secondary consumer and so on.

for certain things like how humans were created and everything like that I totally agree because you can't really do research if something that over the years is probably either hidden or gone so if there wasn't any evidence of how any of this came to be by now it would be gone. some things you just can't put a logical explanation on

Answer:

Favorable variations may allow an organism to be better adapted to its environment and survive to reproduce. Beneficial traits are favored in a population so that they may become better represented. Changes in the genetic makeup of a species may result in a new species; this is biological evolution.
