Answer:
A
Explanation:
Today, the atmosphere holds about 21 per cent oxygen. ... When the first simple organisms appeared in the oceans more than 3.5 billion years ago, the atmosphere was mostly nitrogen, hydrogen, water vapor, and carbon dioxide
The answer is: The reaction rate of the forward reaction would increase in order to decrease the number of particles. (B)
Answer:
Option A) Double-stranded DNA
Explanation:
Note that the presence of thymine, a pyrimidine nitrogenous base in the genome indicates the presence of DNA.
Then, the summation of 28% adenine + 20% thymine + 35% cytosine + 17% guanine to yield 100% confirms that the DNA is double-stranded.
Thus, the structure of the viral genome is Double-stranded DNA.
It is better for the whales to go where the whales have the ability to dive longer and deeper to find cooler water.

Answer:
All are expected to be tall
Explanation:
We are told that the T allele produces the tall trait, and the t allele produces the short trait.
Because the tall allele is denoted by an uppercase letter, it means it is the dominant allele, meaning if it is present even in one copy, the trait will be expressed. This is in contrast to the recessive short allele, 2 copies are needed for the trait to be expressed.
Individuals have 2 copies of every gene. Offspring that are TT, Tt, TT, and Tt all have at least one copy of the T (tall allele). Because this is the dominant allele, that means all of these offspring would be expected to be tall.
