Answer:

Option A

Explanation:

Xeroderma pigmentosum arises as a result of the cell being unable to correct lesions induced by UV. This can be as a result of mutations in the enzymes which include XP A-E needed for correction of the lesions. Failure to correct these lesions leads to their accumulation and then damage to the cell.

Luda [366]

Answer:

1. sympathetic

2. parasympathetic

Explanation:

The sympathetic division of the autonomic nervous system triggers the release of stress hormones from adrenal medulla under emergency conditions. There is a series of physiological responses such as increased heart and breathing rate, an increased flow of blood to skeletal muscles, dilation of pupils, etc. These events helped Nasim to fight the stress conditions.  

Once she was relieved, the parasympathetic system is activated that shut down the physiological responses generated by sympathetic division. It slows down the breathing and heart rate and triggers the digestion and absorption of nutrients to restore the energy level of cells.

As children get older, cultural influences on behavior become much stronger; and as a result, it becomes difficult, if not impos
DanielleElmas [232]

Answer:

False

Explanation:

Sex is a biological term and gender is depended on the roles performed by an individual. In our society it is mandatory for a man or woman to behave and develop sexual preference for its opposite gender and this conservative thought process had strongly held the base of defining a sexual acts which is intended to happen between a male and female only.

However, this is not something defined by nature but by individual likeliness. This is the reason why even after being a male by sex, a male by gender can have likeliness for another male. This is something which cannot be bounded by social and cultural belief even after being into it for years.

Hence, the given statement is false
