Given what we know, we can confirm that the couple in question has a 50% chance that their next child will be a girl.
<h3>Why are the odds 1/2 ?</h3>
This has to do with the fact that each child that the couple has is an independent event. While it is true that it is unlikely for the same event to occur many times in succession, the previous events do not influence the outcome of the next child.
Therefore, given that a child can be either male or female when born, the couple in question has a perfect 50% chance for their next child to be a girl.

Answer:
1. The normal force acting upon the car is best represented by arrow <u>A</u>.
Reason:
The direction of normal force is always upward and opposite to gravitational force that why A is correct option.
2. The force of gravity acting upon the washers is best represented by arrow <u>B</u>.
Reason:
The direction of gravitational force is always downward toward the center of gravity and opposite to normal force that why B is correct option.
3. The applied force on the car is best represented by arrow <u>C</u>.
Reason:
The direction of applied force is along the direction in which it moves. that why C is correct option.
Answer:
RNA
Explanation:
CRISPR system was discovered by a Japanese scientist. Naturally bacteria and many other prokaryotes have CRISPR system in their genome which they use as a self defense against a pathogen which is invading them. It consists of inter spaced, short palindromic nucleotide repeats which encode a guide RNA (gRNA). This guide RNA (gRNA) recognizes the target sequence on the pathogen. The gRNA is followed by Cas9 enzyme which along with the gRNA plays a very important role in breaking genome of the pathogen. Once the target gene is cut down the rest of the DNA can be rejoined by non homologous end joining.
But nowadays, scientists are using this system for genome editing and incorporating desired gene between the two ends which are cut down by CRISPR Cas9 system.

Explanation:
Although Darwinian ideas are purely biological and scientific, they have aided theoretical research in other sciences as well, psychology, in particular. The theory of evolution does not only explain the evolution of the human body, but also that of the brain. The brain's psychological mechanisms and the behaviors they produce can largely be understood through Darwin's theories; the theories of natural and sexual selection have directed much of psychological research.
In general, scientists accept Darwin's theories but in specific fields, such as social psychology and neuroscience, scientists have formulated surprising explanations using Darwinian ideas.
