Answer 1:
The mutation shown is point mutation.
A point mutation can be described as a type of mutation in which only a single nucleotide of a sequence is either:
The addition of the single nucleotide will cause the entire open reading frame to be changed. The amino acid sequence will change entirely from the position where the insertion mutation occurs. This is because the code for making amino acids works on a three base pattern. The reading of the three bases will be altered completely by the addition of just a single nucleotide.
Answer 2:
No, the resulting protein will not be altered.
The genetic code occurs in a linear sequence with triplet format. The change in a single base will cause the wrong amino acids to be formed. However, if the different code is common for the same amino acid then there will be no effect on the amino acid being formed.
<em>For example, the code GUA makes the amino acid Valine. If a mutation occurs and the code becomes GUU instead of GUA, then the resulting amino acid formed will also be Valine. Hence, there will be no alternation in the formation of the protein.</em>
Answer 3:
Melanoma cancer is the type of skin cancer which is associated with cancer from sun light. It is mainly caused due to the harmful ultraviolet rays which act as a mutagen.
<em>The mutations might keep coming back because although the growth have been removed, the other skin cells of the body might still have the mutation in them. As a result, growth will be seen again in the skin cells which might occur again and again. </em>

Explanation:
Answer: The heat index is an index that combines air temperature and relative humidity, in shaded areas, to posit a human-perceived equivalent temperature, as how hot it would feel if the humidity were some other value in the shade.
Explanation: did the test
The answer is "D"
The body's first line of defense is also known as Innate immunity and incudes mucous membranes. Both the intact skin and mucous membranes of the body offer a high degree of protection against pathogens.
A good example is the mucous membrane of the respiratory tract. It is lined up with cilia and covered with mucus. The coordinated beating of the cilia drives the mucus up to the nose and mouth where the trapped bacteria can be expelled.
(Lymph nodes and white blood cells belong to the second line of defense, not the first)
Answer:
b. 80
Explanation:
There are about 4 calories per gram of carbohydrates. As such, if 20 grams of carbohydrate are provided, simply multiply 4 calories per gram with the total amount of grams of carbohydrates.
<em>20 grams of carbohydrates</em> x <em>4 calories per gram of carbohydrates</em> = 80 calories total.

Answer:
The all possible gametic haplotypes that can be made are described below.
Explanation:
According to the question, F1 progeny was produced by crossing a homozygous dominant parent with a homozygous recessive parent. As per the question, cross is to be made with a heterozygous parent, which will have solid unpatterned allele and blue colour with a homozygous recessive i.e lined, aqua lizard.
The possible haploid gametes for the heterozygous parent would be BL, bl, Bl, bL and for homozygous parent would be all bl.
