Which of the following is not a state function?

Options:
A Volume
B Pressure
C Entropy
D Heat

The correct answer is:

Solution:
The paragraph states that heat is not a state function. This means that the change in heat of a system depends on the path taken to reach the final state. For example, if we heat a system from 25°C to 35°C by passing a current through it, the amount of heat required will be different from the amount of heat required if we heat the system by placing it in a hot bath

Which of the following is not a stem modification?

Options:
A Pitcher of Nepenthes
B Thorns of Citrus
C Tendrils of cucumber
D Flattened structures of Opuntia

The correct answer is:
Pitcher of Nepenthes

Solution:
Pitcher of Nepenthes is a modification of the leaf. Nepenthes species usually produce two types of pitchers, known as leaf dimorphism. Appearing near the base of the plant are the large lower traps, which typically sit on the ground. The upper or aerial pitchers are usually smaller, coloured differently, and possess different features from the lower pitchers. These upper pitchers usually form as the plant reaches maturity and the plant grows taller. To keep the plant steady, the upper pitchers often form a loop in the tendril, allowing it to wrap around for nearby support.

Which of the following is not a symptom of hypothyroidism?

Options:
A Oedema
B Lethargy
C Rise in blood urea
D Mental retardation

The correct answer is:
Rise in blood urea

Solution:
Hypothyroidism is a deficiency of thyroid hormones ( T3 and T4 ). As thyroid glands fail to produce thyroid hormones there is a feedback to the pituitary due to which TSH increases. Thyroid hormones are responsible for metabolism hence in case of deficiency the metabolism of the body slows down and thus weight of the person increases. This also causes water accumulation. Since there is no metabolism, a person has no energy to perform work and this causes lethargy. If this deficiency occurs in children this will result in retarded mental health.Urea is a nitrogenous waste and its accumulation is related to kidney function.

Which of the following is not an autoimmune disease?

Options:
A Alzheimer's disease
B Rheumatoid arthritis
C Psoriasis
D Vitiligo

The correct answer is:
Alzheimer's disease

Solution:
An autoimmune disease is a condition in which your immune system mistakenly attacks your body.
The immune system normally guards against germs like bacteria and viruses. When it senses these foreign invaders, it sends out an army of fighter cells to attack them.
Normally, the immune system can tell the difference between foreign cells and your own cells.
In an autoimmune disease, the immune system mistakes part of your body — like your joints or skin — as foreign. Thus, it loses its ability to differentiate between the self and non-self antigens. In response to these antigens, it releases proteins called antibodies that attack healthy cells.

Ex- Rheumatoid arthritis, Psoriasis, vitiligo

Alzheimer's disease is not an autoimmune disease. It is a progressive disorder caused by a combination of genetic, lifestyle and environmental factors that affect the brain over time. People suffering from Alzheimer's disease have a difficulty in remembering day to day activities, eventually leading to dementia.
