Fatigue is mostly associated with

Options:
A repeated stimulation of muscles
B excessive work load on muscles
C anaerobic respiration in muscles
D all of these

The correct answer is:
all of these

Solution:
Muscle fatigue is extreme tiredness of muscles. This is due to many reasons. Overload on muscles is the commonest cause. This is because muscles are under repeated stimulations. This results in exhaustion of minerals like calcium inside the muscles. This also results in depletion of oxygen and thus there is accumulation of lactic acid inside the muscles. If such a state arises, resting the muscle is the first step. This will result in removal of lactic acid from the muscles and thus muscle fibres will get oxygen supply again.

Fats are broken down into glycerol and fatty acids with a series of chemical reactions occurring in the digestive tract. The fatty acids are then absorbed through the small intestine and enter lacteals. The excess of such fatty acids gets converted into fats and are stored in the adipose tissue present in the subcutaneous layer. Under starvation, the fatty acids are mobilized to be used as energy during cellular respiration. These fatty acids during cellular respiration are first broken down into

Options:
A Pyruvate
B Succinate
C Oxaloacetic acid
D Acetyl Co-A

The correct answer is:
Acetyl Co-A

Solution:
Fatty acids are first degraded to acetyl CoA and during the Ã-oxidation of the fats. This acetyl Co-A then enters into the Kreb's cycle to be broken down into CO2 and produce energy finally by terminal oxidation of NADH2 and FADH2.

Feeling the tremors of an earthquake a scared resident of seventh floor of a multistoryed building starts climbing down the stairs rapidly. Which hormone initiated this action?

Options:
A adrenaline
B glucagon
C gastrin
D thyroxine.

The correct answer is:
adrenaline

Solution:
Adrenaline or epinephrine is an emergency hormone, which is responsible for this action as it is known as the $3 \mathrm{~F}$ hormone-fright, flight and fight hormone. Glucagon increase blood sugar level, and is stimulated by adrenal glands during emergency condition. Similarly, Thyroxine increase regulates metabolic rate and is stimulated during the condition. Gastrin is a peptide hormone primarily responsible for enhancing gastric mucosal growth, gastric motility, and secretion of hydrochloric acid $(\mathrm{HCl})$ into the stomach. It is present in $\mathrm{G}$ cells of the gastric antrum and duodenum.

Fern prothallus is developed from

Options:
A Elaters
B Spore mother cells
C Spore
D Zygote

The correct answer is:
Spore

Solution:
In ferns, spores germinate to form a prothallus.

Ferns are known as homosporous plants. The sporangia are usually in clusters known as sori, found on the underside of the fern leaves. Some ferns have a covering over the sporangia known as an indusium. When the spores are mature, they are released from the sporangia. If a spore lands on a suitable site, it will germinate and grow via mitosis into a mature gametophyte plant (prothallus). A gametophyte is a plant that produces gametes.
