Answer:
The proportions of nucleotides in the newly formed complimentary strand will be:
14% Thymine (T), 33% Adenine (A), 21% Guanine (G), 32% Cytosine (C).
Explanation:
In a double stranded DNA, the nucleotides of one strand binds with nucleotides of another strand through hydrogen bonds.
Adenine binds with thymine by two hydrogen bonds (A=T) and guanine binds with cytosine by three hydrogen bonds (G≡C).
So, the complimentary strand must have
- thymine equal to the amount of adenine in template strand.
- adenine equal to the amount of thymine in template strand.
- guanine equal to the amount of cytosine in template strand.
- cytosine equal to the amount of guanine in template strand.
Answer:
A. single-gene
Explanation:
It is controlled by a single gene that has two alleles. The allele for a widow's peak is dominant over the allele for a hairline with no peak.
Answer:
Lobsters are adapting to cooler temperatures.
Explanation:
Adaptation may be defined as the phenomena that involves the physical, physiological and chemical changes in the organisms that helps to adapt themselves in their environmental condition.
The adaptation may bring genetic changes in the next generation as well. The lobsters movement per year demonstrates that they are trying to adapt in their environment. The cooler temperatures is favorable for the growth and adaptation of Lobsters.
Thus, the answer is Lobsters are adapting to cooler temperatures.
Answer: The main organ of the integumentary system is the skin.
Explanation: The skin regulates body temperature, keeps germs from entering your body, and produces vitamin D to help absorb calcium.
The criteria pollutants are carbon monoxide, lead, nitrogen dioxide, ozone, particulate matter, and sulfur dioxide.
