The basic unit of life is a cell. Have a great day!
Look it up online, look up a copy of the Articles of confederation and fill it in! Best I can do for you my friend
Answer:
(A) -> (D) -> (C) -> (B)
Explanation:
First off, given that the problem requires us to explain how life on Earth may have arisen <u>from terrestrial origins</u>, we can discard sentence (E), as impacts from meteorites would count as extraterrestrial origins.
Then it's just a matter of describing the steps by which simple compounds turned into more and more complex structures, that would in turn lead to the origin of life.
Simple inorganic compounds (such as CO₂, or NH₃) were exposed to energy, because of that they formed simple organic molecules, like carbohydrates or amino acids.
These organic molecules, in turn, would self-assemble into more complex structures, such as proteins.
Lastly, there's the phenomenon of Compartmentalization, where large organic structures became enclosed within a membrane-like structure, separating them from the 'outside' medium and thus creating primitive cells.
Answer:
Explanation:
If there are 5 genes, let us assume that they are in the alternative forms with 2 possible gets for each five... So we have
2 possible gametes for each five = 2 to the power of 5 = 32 gametes
Then genotypes = 3 to the power of 5 = 243
The same also for 10 genes
2 possible gametes for each 10 = 2 to the power of 10 = 1024 gametes
Then genotypes = 3 to the power of 10 = 59,049
The same also for 20 genes
2 possible gametes for each 20 = 2 to the power of 20= 1,048,576
Them genotypes = 3 to the power of 20 = 3,486,784,401
