Answer:
A. DNA polymerase
Explanation:
DNA polymerases (I,II,III) proofread the DNA, which helps to catch errors. Errors can be fatal to expression, creating misformed proteins or unclear information, so this is necessary.
Fun facts - the coronavirus is a retrovirus, so it doesn't proofread. That makes it much harder to find a vaccine, because it can generate new strains by the very fact of not proofreading.
<em>2:4 homozygous recessive; 50% heterozygous.</em>
Explanation:
I will be using the letter B to represent dominant alleles and b to represent recessive alleles.
If a canary is heterozygous, that means that it will have (Bb). Hetero, means different, so it will <em>never </em>be both (BB) or (bb).
If the other canary is homozygous recessive, it will be (bb). Homo, means the same, so it will <em>never </em>be (Bb). If the canary were homozygous dominant, it would be (BB).
I made a Punnett square to figure out the ratio and the percentage that is being asked in the question. As you can see, if you bring down the alleles from both of the parents accordingly, you will get...
<u>2:4</u> of the offspring will be potentially <u>homozygous recessive</u>.
<u>50%</u> of the offspring will be <u>heterozygous</u>.
Answer:
The correct answer is NUTRIENT CONTENT CLAIM
.
Explanation
In markets you have seen a lot of fast food items which are labelled with tag in which nutrients composition along with their quantity in gram is also mentioned. It tells about the nutrients variety and their quantity. This is a nutrient content claim.
The Declaration contained 3 sections: a general statement of natural rights theory and the purpose of government; a list of grievances against the British King; and the declaration of independence from England.
The Declaration of Independence is made up of five distinct parts: the introduction; the preamble; the body, which can be divided into two sections; and a conclusion.
