Explanation

Cooking is difficult in the mountains primarily due to low atmospheric pressure, which affects the boiling point of water. 

Decreased Pressure at High Altitude:

As altitude increases, the atmospheric pressure decreases because there is less air pushing down from above.

Lower Boiling Point:

Water boils when its vapor pressure equals the surrounding atmospheric pressure.

With lower pressure on mountains, water needs less heat to reach its boiling point, so it boils at a lower temperature than the 100°C (212°F) it does at sea level.

Slower Cooking:

Since food cooks based on temperature, boiling it in water that is not as hot (e.g., 92°C at 8,000 feet) means the cooking process takes significantly longer to achieve the same result as at sea level. 

Explanation

Diabetes cause due to mall functioning of pincrease

The three main types of diabetes are:

Type 1 diabetes

Type 2 diabetes

Gestational diabetes

Type 1 diabetes

Type 1 diabetes is believed to be an autoimmune condition. This means your immune system mistakenly attacks and destroys the beta cells in your pancreas that produce insulin. The damage is permanent.

Type 2 diabetes

Type 2 diabetes starts as insulin resistance. This means your body can’t use insulin efficiently. That stimulates your pancreas to produce more insulin until it can no longer keep up with demand. Insulin production decreases, which leads to high blood sugar.

Gestational diabetes

Gestational diabetes is due to insulin-blocking hormones produced during pregnancy. This type of diabetes only occurs during pregnancy.

Explanation

Pneumonia is a form of acute respiratory infection that affects the lungs

The lungs are made up of small sacs called alveoli, which fill with air when a healthy person breathes

Explanation

Tetanus is caused by the bacterium Clostridium tetani.

The other options are caused by different pathogens:

• Malaria is caused by a parasite (Plasmodium) transmitted through mosquito bites.
• Cancer is not caused by bacteria; it is a group of diseases involving abnormal cell growth.
• Rabies is caused by a virus (Rabies virus), not bacteria.

Explanation

The push-up test is a common exercise that measures upper-body strength endurance.

By performing as many push-ups as possible with proper form,

You can assess your muscular endurance in the chest, shoulders, and arms.  

Explanation

• The Earth is tilted at an angle of 23.5 degrees.
• This tilt is responsible for the changing of the seasons and the difference in the amount of sunlight reaching a given point on the surface during the course of a year.
• The tilt varies between 22.1 and 24.5 degrees in a cycle that averages about 40,000 years.

Explanation

The age of a tree is determined by counting its growth rings.

They are visible in the cross-section of the stem.

Each ring represents one year of growth.

Explanation

A sphygmomanometer also known as a blood pressure monitor.

It is a device used to measure blood pressure.

A normal blood pressure level of 120/80 mmHg.

High-normal: 130 to 139 mmHg

High: Greater than 140 mmHg

while

mmHg stands for "Millimeter of Mercury"

Explanation

White Corpuscles, or White Blood Cells (WBCs), or Leukocytes, act as a defense mechanism by fighting infections and diseases in the body.

They play a key role in the immune system.

They help fight infections and protect the body against foreign substances, such as bacteria, viruses, and other pathogens.

Explanation

Blood cells are made in the bone marrow.

The bone marrow is the soft, spongy material in the center of the bones.

It produces about 95% of the body's blood cells.
