Answer:
The answer is letter a, chemical evolution.
Explanation:
Chemical Evolution <u>is one of the processes that helps explain the origin of life. It states that the first living cell on earth started from non-living matters that were not capable of reproducing.</u>
This <em>non-living matter </em>could be both <em>organic and inorganic molecules.</em> It is said that the structures of these molecules changed over time (example is protein breaking down when exposed to too much heat). When these systems become complex, they form new structures (this is known as repetitive reproduction). This then gives rise to bacteria.
Thus, this explains the answer.
Bacteria helps degrade dead animals and plants and bring valuable nutrients back to Earth.
Answer:
Option C, 
Explanation:
The diploid number of chromosomes are represented as 
.
Here the somatic chromosome number is 
which can be represented in the "" format with N being equal to 
.
Now, as we know that the total number of chromosomal combination with chromosome number being
is equal to
Substituting the given values in above equation, we get -
Therefore, total of different combinations of centro-meres could be produced during meiosis.
Hence, option C is correct
The terrain of a biome has lots of different effects on its climate. For example, the sand of a desert absorbs heat and water, so it is constantly hot and it rarely rains.
I hope this helps.
