Please help, 100 points! Most scientists agree that life began on earth approximately 3.5 billion years ago. What would a scientist need to do in order to test this hypothesis and gather evidence?
A: Recreate the composition of the atmosphere and oceans on Earth as they were 4.5 billion years ago.
B: Travel to a similar planet or moon in its own early formation and recreate the chemical reactions which took place on Earth.
C: Gather the raw materials, such as inorganic compounds, on Earth 4.5 billion years ago and recreate the chemical reactions that could have taken place.
D: This is not a testable hypothesis since there is no way to travel back 4.5 billion years or to run the experiment for the next 4.5 billion years. (This one is obviously wrong)
Answers
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.
What is the origin of life?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.

What can be concluded about the importance of mitosis in repairing cuts on the skin?
Mitosis is helpful but not necessary in repairing cuts on the skin.
O Mitosis is a necessary step in repairing cuts on the skin.
O Mitosis slows down the process of repairing cuts on the skin.
Mitosis is not involved in repairing cuts on the skin.
Answers
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.

why do plants look green?
Answers
Answer:
The longer answer lies in the details of photosynthesis, the electromagnetic spectrum, energy and “special pairs” of chlorophyll molecules in each plant cell. ... As such, plants look green because they absorb red light most efficiently and the green light is reflected.
Explanation:
Green plants are green because they contain a pigment called chlorophyll. Chlorophyll absorbs certain wavelengths of light within the visible light spectrum. ... Green light is not absorbed but reflected, making the plant appear green. Chlorophyll is found in the chloroplasts of plants
Answer:
Plants look green because of a natural pigment called chlorophyll, which absorbs the red, blue, and other wavelengths of light, and it reflects the green back to your eyes, so that is what you see. Chlorophyll traps the light from the sun to be used for photosynthesis, so without chlorophyll, plants could not survive!

If the code on the template DNA strand is TACGCA the RNA built from that template during transcription would have the sequence type your answer..
Answers
Answer:
AUGCGU
Explanation:
According to the base-pairing rule, Thymine (T) always pairs with Adenine (A), and Cytosine (C) always pairs with Guanine (G). In addition, RNA has Uracil (U) in the place of Thymine. Following these two rules, TACGCA is transcribed as follows:
T A C G C A
A U G C G U
Hence, the transcription product of TACGCA is AUGCGU.

how do variations lead to adaptations?
Answers
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.

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
