Cancer cells are more easily damaged by radiation than normal cells because they are:

Options:
A starved of mutation
B undergoing rapid division
C different in structure
D non-dividing.

The correct answer is:
undergoing rapid division

Solution:
Cancer cells multiply faster than normal cells in the body. Because radiation is most harmful to quickly growing cells, radiation therapy damages cancer cells more than normal cells. This prevents the cancer cells from growing and dividing, and leads to cell death.
Related Theory
Characteristics of cancer cells
- Uncontrolled potential to divide and do not response to programmed cell death, or apoptosis.
- Show Metastasis i.e., they can migrate and spread to other organs and tissues by travelling through the bloodstream.
- Angiogenesis is the formation of new blood vessels from existing blood vessels to meet their high oxygen demand.
- shows chromosomal abnormalities

Cancerous cells can be easily destroyed by radiations due to:

Options:
A rapid cell division
B lack of nutrition
C fast mutation
D lack of oxygen

The correct answer is:
rapid cell division

Solution:
Cancer cells rapidly undergo mitosis. Cancer cells which divide rapidly are less organized than healthy cells. Cancerous cells can easily be destroyed by radiation due to the ability of radiations to kill cells is highest in the tissue with highest number of dividing cells. Hence, tumours are killed more rapidly by radiations.

Capacitation occurs in

Options:
A Rete testis
B Epididymis
C Vas deferens
D Female Reproductive Tract

The correct answer is:
Female Reproductive Tract

Solution:
Capacitation is an increase in the fertilizing capacity of the sperms, through several changes which occurs in the female reproductive tract. It is a functional maturation of the spermatozoon. The changes take place via the sperm cell membrane in which it may be that receptors are made available through the removal of a glycoprotein layer. The area of the acrosomal cap is also so altered thereby that the acrosome reaction becomes possible.

Topic: Biology, Human Reproduction, NEET, NEET 2017
Capacitation refers to changes in the:

A Sperm before fertilization
B Ovum before fertilization
C Ovum after fertilization
D Sperm after fertilization

The correct answer is:
Sperm before fertilization

Solution:
Sperm capacitation refers to the physiological changes spermatozoa must undergo in order to have the ability to penetrate and fertilize an egg. The changes take place via the sperm cell membrane in which it may be that receptors are made available through the removal of a glycoprotein layer. The area of the acrosomal cap is also so altered thereby that the acrosome reaction becomes possible.

Capacitor C1 of capacity 1 Î¼F and capacitor C2 of capacity 2 Î¼F are separately charged fully by a common battery. The two capacitors are then separately allowed to discharge through equal resistors at t=0

Options:
A At t=0 the value of current in the circuit containing 1Â Î¼F is more than current in the circuit containing 2Â Î¼F
B At t=0 the current in 2Â Î¼F capacitor circuit is more than current in 1Â Î¼F capacitor circuit
C 1 Î¼F capacitor losses 50 % charge sooner than 2 Î¼F capacitor
D 2 μF capacitor losses 50 % charge sooner than 1 μF capacitor

The correct answer is:
1 Î¼F capacitor losses 50 % charge sooner than 2 Î¼F capacitor

Solution:
Total potential difference E0 is given to both of the capacitor.
The two capacitors are then separately allowed to discharge through same resistors.
Since both capacitors are charged to same potential difference hence current at t=0 , I0=E0R will be same in both circuits.
Time taken in 50 % discharging =RCln(2)
As 1st capacitance is 50% less than that of 2nd capacitance,
hence 1 Î¼F will take less time compared to 2 Î¼F

Carbohydrates are commonly found as starch in plant storage organs. Which of the following five properties of starch (A-E) make it useful as a storage material?
(A) Easily translocated
(B) Chemically non-reactive
(C) Easily digested by animals
(D) Osmotically inactive
(E) Synthesized during photosynthesis
