Answer:
The <u>vas deferens</u> transports mature sperm to the urethra in preparation for ejaculation.
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:
Option 3 and 4 are most likely correct
Explanation:
<em>Option 3</em>: We know that area 1 would contain heavy streaking and not single colonies. Therefore, if the loop crosses area 3 and enters area 1, it will definitely result in heavy streaking again.
<em>Option 4</em>: We always need to sterilize properly the loop when streaking in different areas. If we don't do it, it is possible that the loop contains a lot of bacteria that would be streaked again.
Options 1 and 2 are incorrect because, according to question, there is a uniform growth but no isolated colonies. So, contamination or mixed culture would not produce uniform growth streaking rather mixed with other bacterial types.
The examples of species changing over time are statements A, C, and D.
All these changes, such as new types of squash was developed in the garden. weeds evolution to resist chemicals, and the changes in butterflies wing pattern over the years is because of Mutation. Obviously, rabbit's ears are always bigger than mice and Giraffe's neck is always longer than the deer's. In genetics, mutation is the process of permanent alternation of the nucleotide sequence in DNAs.
