Yes, meiosis is strictly dealing with your gonads which are your gametes (testes/ovaries). It would not produce a diploid sex cell but rather 4 totally genetically different haploid cells. It can best be seen as 2n becomes n. In mitosis you can have 1n to 1n or 2n to 2n because in mitosis you have 2 identical daughter cells exactly like the parent cell.
The answer is m.
Centripetal force (F) is a force that makes body move around a circular curve. The unit of force is N (N = kg * m/s²).
It can be represented as:<span>
</span><span><span> <span> <span> <span> <span> <span> <span> <span> <span> <span> <span> <span> <span> <span> </span></span></span></span></span></span></span></span></span></span></span></span> <span> </span></span></span><span> </span></span><span>
where:
m - mass
v - velocity
r - radius of the curve
We have:
m = 1,200 kg
V = 20 m/s
F = 6,000 N = 6,000 kg * m/s²
We need radius of the curve:
r = ?
So, if </span><span> </span><span>, then:
</span><span> </span><span>
</span>⇒ <span> </span><span>
</span>⇒ <span> </span><span>
</span>⇒ <span> </span><span>
</span>⇒<span> </span><span> </span>
<h2>
Answer:</h2>
Option A. Bacteria.
<h2>
Explanation:</h2>
- It is presumed that, over millions of years of evolution, abiotic molecules evolved into the self-replicating molecules by means of natural selection.
- Cyanobacteria, or blue-green algae is a bacteria which was one of the oldest fossils found on earth. These microbes conduct photosynthesis: using sun light, water and carbon dioxide to produce carbohydrates and oxygen.
- Cynobacteria played a major role in forming oxygenated atmosphere.
- The first living things on the planet Earths was single-celled micro-organisms which lack a well defined cell nucleus were known as prokaryotes, and bacteria belongs to prokaryotes ans hence among given options bacteria matches the most for the first life form on earth.
Result: Among the given choices bacteria was most similar to first living things on earth.
