Which of the following is the structure through which blood exits the glomerulus?
Efferent arteriole
Proximal tubule
Distal tubule
Afferent arteriole.
The Correct Answer is A
The glomerulus is the main filtering unit of the kidney.
It is formed by a network of small blood vessels (capillaries) enclosed within a sac called the Bowman’s capsule.
The blood supply to the glomerulus is provided via the afferent arteriole.
The blood then flows through the capillary network, where it gets filtered, and then leaves the glomerulus via the efferent arteriole.
Choice B. Proximal tubule is not correct because it is where the ultrafiltrate collected in the Bowman’s space drains directly into.
Choice C. Distal tubule is not correct because it is not mentioned in relation to blood exiting the glomerulus.
Choice D. Afferent arteriole is not correct because it provides blood supply to the glomerulus.

Correct Answer is C
Explanation
A control group is a group in an experiment that does not receive the treatment or manipulation being tested and is used as a benchmark to measure how the other tested subjects do.
The control group is used to minimize the effects of all variables except the independent variable.
This allows researchers to determine if changes in the dependent variable are due to the manipulation of the independent variable or if they are due to some other factor.
Choice A. Responding is not the correct answer because it refers to the dependent variable, which is the variable that is being measured in an experiment.
Choice B. Manipulated is not the correct answer because it refers to the independent variable, which is the variable that is being manipulated in an experiment.
Choice D. Variable is not the correct answer because it refers to any factor that can change in an experiment and can include both independent and dependent variables.
Correct Answer is C
Explanation
In this cross, both parents are homozygous recessive for the smooth leaf trait (ff).
This means that all of their offspring will inherit two copies of the recessive allele (f) and will therefore have smooth leaves.
Choice A. FF x FF is not correct because both parents are homozygous dominant for the fuzzy leaf trait (FF) and all of their offspring will inherit two copies of the dominant allele (F) and will therefore have fuzzy leaves.
Choice B. Ff x Ff is not correct because both parents are heterozygous for the leaf trait (Ff) and their offspring can inherit either one dominant allele (F) or one recessive allele (f) from each parent, resulting in a 3:1 ratio of fuzzy to smooth leaves.
Choice D. Ff x ff is not correct because one parent is heterozygous for the leaf trait (Ff) while the other is homozygous recessive (ff), resulting in a 1:1 ratio of fuzzy to smooth leaves in their offspring.
