Natural selection is the process in which the more favorable traits due to mutation that are in a select few in a population produce more offspring then others. An example of this is bacteria resistant to antibiotics due to the faster reproduction of the resistant bacteria over the non resistant ones
<h2>Point mutation.</h2>
Explanation:
- The protein will be unchanged.
Mutation is defined as a change in nucleotide sequence of a gene. When a single nucleotide is inserted,deleted or substituted in a DNA sequence, then the resulting mutation is classified as point mutation.
A gene contains two region- intron region and exon region.
The region that codes for a particular protein is called the exon and the region that separates two exons and does not code for any protein is called the intron.
Most of the point mutations in the intron region are silent except if it is located at the splice site recognition sequence.
In the given situation the mutation is in the middle of the intron region so there is no chance of it being a splice site recognition sequence. Hence the protein will remain unchanged.
Obligate parthenogenesis is the process in which organisms exclusively reproduce through asexual means. Many species have been shown to transition to obligate parthenogenesis over evolutionary time.

Answer:
<h3>C. 6.50 x 10^3</h3>
Explanation:
The satellite revolves around moon due to centripetal force which is provided by gravity in this context so we can equate gravity and centripetal force.
where, m is mass of satellite
M is mass of moon
ω is angular velocity
G is Universal gravitational constant
R is the radius of moon
from the above equation we get ω as,
here M = 7.36 X 10^22
R = 1.738 X 10^6
G =6.67 X 10^-11
T= 6.50 X 10^3 seconds
