Assertion:Choroid layer is thick over the posterior two-third of the eye ball but it becomes thin in the anterior part.
Reason:Choroid layer lacks blood vessels It forms ciliary body in the anterior part of the eye ball.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that the choroid layer is thick over the posterior two-thirds of the eyeball but becomes thin in the anterior part. - This statement is **incorrect**. The choroid layer is actually thick in the anterior part of the eyeball where it forms the ciliary body and thin in the posterior part. 2. **Understanding the Reason**: - The reason states that the choroid layer lacks blood vessels and forms the ciliary body in the anterior part of the eyeball. - This statement is also **incorrect**. The choroid layer is rich in blood vessels and does indeed form the ciliary body in the anterior part, but it does not lack blood vessels. 3. **Conclusion**: - Since both the assertion and the reason are incorrect, the correct answer to the question is that both the assertion and the reason are false. ### Final Answer: Both assertion and reason are false.

When an object moves through a fluid, as when a ball falls through air or a glass sphere falls through water te fluid exerts a viscous foce F on the object this force tends to slow the object for a small sphere of radius r moving is given by stoke's law, F_(w)=6pietarv . in this formula eta in the coefficient of viscosity of the fluid which is the proportionality constant that determines how much tangential force is required to move a fluid layer at a constant speed v, when the layer has an area A and is located a perpendicular distance z from and immobile surface. the magnitude of the force is given by F=etaAv//z . For a viscous fluid to move from location 2 to location 1 along 2 must exceed that at location 1, poiseuilles's law given the volumes flow rate Q that results from such a pressure difference P_(2)-P_(1) . The flow rate of expressed by the formula Q=(piR^(4)(P_(2)-P_(1)))/(8etaL) poiseuille's law remains valid as long as the fluid flow is laminar. For a sfficiently high speed however the flow becomes turbulent flow is laminar as long as the reynolds number is less than approximately 2000. This number is given by the formula R_(e)=(2overline(v)rhoR)/(eta) In which overline(v) is the average speed rho is the density eta is the coefficient of viscosity of the fluid and R is the radius of the pipe. Take the density of water to be rho=1000kg//m^(3) Q. Blood vessel is 0.10 m in length and has a radius of 1.5xx10^(-3) m blood flows at rate of 10^(-7)m^(3)//s through this vessel. The pressure difference that must be maintained in this flow between the two ends of the vessel is 20 Pa what is the viscosity sufficient of blood?
