Explanation

The retina is a thin layer of tissue that lines the back of the eye on the inside.

It is located near the optic nerve.

The purpose of the retina is to receive light that the lens has focused,

convert the light into neural signals,

and send these signals on to the brain for visual recognition

Explanation

Vitamin A deficiency can cause both loss of appetite and night blindness.

It is also known to increase susceptibility to infections, including those in the throat. 

Night blindness

This is one of the earliest signs of vitamin A deficiency.

It is the inability to see well in low-light conditions, which is caused by the lack of a specific pigment needed for the retina to function properly. 

Loss of appetite

Vitamin A is involved in the health of the receptors for taste and smell.

When vitamin A is deficient, these senses can be altered, which leads to a reduced appetite and difficulty consuming enough nutrients. 

Explanation

Biological death of the patient means death of tissues of the brain.

Explanation

How does the Navstar GPS work for different applications? (5)

The Navstar GPS works by using a constellation of satellites that send signals to GPS receivers on the ground, allowing them to calculate precise location coordinates.

It is used in various applications like navigation, mapping, surveying, military operations, and location tracking for vehicles and personal devices.

Explanation

• The de-oxygenated blood from the heart comes to the lungs through the Pulmonary artery
  ***
• The deoxygenated blood returns from the body to the right atrium and from there enter the right ventricle that pumps it to the lungs through the main pulmonary artery (pulmonary trunk).
• ****
• The pulmonary veins transport oxygenated blood back to the heart from the lungs
  

Explanation

The presence of lactic acid in milk is due to the fermentation of lactose caused mainly by lactic bacteria

Explanation

Deficiency of Iodine causes Goitre disease.

Thyroxine is a hormone that causes Goitre in the human body.

Explanation

Insulin is a hormone made by an organ located behind the stomach called the pancreas.

There are specialised areas within the pancreas called islets of Langerhans

The term insulin comes from the Latin insula that means island.

Explanation

All important questions and Information Related to 'Photosynthesis"

Photosynthesis takes place in presence of the following light Only in sunlight from the sun

Photosynthesis takes place faster in white light

Photosynthesis occurs more in blue and red light rays

Photosynthesis occurs more in blue and red light rays and less, or not at all, in green light rays.

Green Light light is more important for photosynthesis.

As compared to photosynthesis, glucose is chiefly decomposed during Respiration

At the time of a Solar Eclipse, the rate of photosynthesis will: Decrease

In all plants, the major sites of photosynthesis are Leaves

In Photosynthesis reduction occurs in the Water

At night, when photosynthesis is stopped, plants Give off Carbon Dioxide.

Photosynthesis pigments are organized into clusters called thylakoid

The process of photosynthesis produces glucose and carbon dioxide
