2 would be A because fertilization is where the sperm cell and egg unite. 3 would be C because in the picture you can see how the division is occuring.
The answer is Brachial Plexus. Brachial Plexus Injury is the result of pulling or stretching the arm forcibly. Sudden damage to the nerves, weakness, loss of sensation and movement are the most common symptoms of a brachial plexus injury.
The attached picture shows how bacteria gain antibiotic resistance. Firstly, a few individuals attain a
beneficial mutation in their genetic material that accords them the capability to survive in an antibiotic. The
individuals are hence able to survive and
reproduce more than those individuals without the mutation. There is, therefore, a genetic
shift in the population in favor of the resistant genotype. After generations, the
whole population becomes antibiotic resistant.
Answer:
<u> </u><u>The magnitude of the force exerted by the biceps </u><u> is 218.38N</u>
<u>The magnitude of the force exerted by the elbow </u><u> is 194.37N</u>
Explanation:
Firstly , lets calculate the magnitude of force exerted by biceps -
Mass of the forearm=
Mass of the ball =
= 0.950kg
so, weight of the forearm=
g
weight of the ball=
g
Now , balancing torque about the elbow , we have-
(here , distance of the bicep is 2.50cm = 0.025m and distance of the ball is 36cm= 0.36m)
Now putting the given values in the formula -
Now, lets calculate the force exerted by elbow -
Balancing the vertical forces
