Explanation

• Blood is slightly alkaline, with a pH range of 7.35 to 7.45.
• This narrow pH range is tightly regulated by the body's acid-base homeostasis mechanisms to ensure proper functioning of various physiological processes.

Explanation

• Black currants are one of the richest sources of vitamin C, with a single serving providing approximately 180% of the recommended daily intake.
• They contain around 34-41 mg of vitamin C per 1/4 cup.

Explanation

The pressure of oxygen in the lungs is 104 torr. 

The partial pressure of oxygen in the lungs, also known as the alveolar partial pressure of oxygen (PaO2),

It is the pressure exerted by oxygen within the alveoli.

At sea level, atmospheric pressure is 760 mmHg.

Since oxygen makes up approximately 21% of air,

The partial pressure of oxygen in atmospheric air is 0.21 x 760 mmHg = 159.6 torr

However, as air enters the alveoli, it mixes with water vapor and carbon dioxide, which slightly reduces the oxygen partial pressure.

Therefore, the actual partial pressure of oxygen in the alveoli is around 104 torr. 

Explanation

The active movement of mitochondria in the cytoplasm is due to cyclosis, also known as cytoplasmic streaming.

Explanation

Amino acids are a product of the digestion of proteins.

During digestion, proteins are broken down into amino acids.

They are then absorbed and used by the body for various functions.

Explanation

An early sign of anoxia is headache.

Headaches can occur due to reduced oxygen levels affecting the brain.

It often preceding more severe symptoms like cyanosis or confusion.

Explanation

The most comfortable position for a patient with congestive heart failure is High Fowler.

This position helps ease breathing by reducing abdominal pressure on the diaphragm and improving lung expansion.

Explanation

Chloroplasts are the organelles responsible for photosynthesis in plant cells

And contain chlorophyll, which captures light energy.

In plants and algae, which developed much later, photosynthesis occurs in a specialized intracellular organelle—the chloroplast.

Chloroplasts perform photosynthesis during the daylight hours.

Explanation

A wound should be covered with a roller bandage to prevent infection and dirt from getting inside.

Explanation

Cole crops is also known as brassicas.

They are a group of vegetables belonging to the Brassicaceae family.

Including cabbage, cauliflower, broccoli, and knol-khol (kohlrabi).
