Answer:
b. Even though the DNA sequence changed, the sequence still codes for the same amino acid, so no change in phenotype will occur.
Explanation:
There is redundancy in the genetic code. That means that different codons can code for the same amino acids, so some mutations do not change the amino acid sequence of the protein.
Here, the amino acid is unchanged with the mutation.
If the amino acid sequence of the protein is the same, then the protein is not changed, so there will be no change in the phenotype
The statement that highlights and describes in detail the key features of an aquatic animal would be produce qualitative data analysis as we will describe its external features such as color size etc.
Answer: Option A "Choroid plexus".
Explanation:
Cerebrospinal fluid can be defined as the fluid that is found in the brain and spinal cord of human beings. It is a clear and colorless fluid.
The production of cerebrospinal fluid takes place by the specialized ependymal cells that lies in the choroid plexuses which is present in the ventricles of brain.
The amount of cerebrospinal fluid in a day is 500mL. This fluid acts as cushion that protects the brain from mechanical and immunological protection.
Hence, the correction answer is option A
Answer:
<h2>(14+16)/1000 *100= 3</h2>
Explanation:
Parental combinations are always more common then other recombinant progenies.
A female fly is heterozygous for three X-linked genes crossed with an abc/Y male. . If single crossover occurs between a & b and between b & c, then the double cross is that, which occurs in both.
Double cross over progeny are always least in number, so here double cross occurs are in abC 14 and ABc 16.
So we are expecting that number of double cross over progeny= (14+16)/1000 *100= 3
