Explanation

Pepsin is a digestive enzyme that breaks down proteins into smaller peptides and amino acids.

It is produced in the stomach and is activated by hydrochloric acid.

Pepsin is essential for the digestion of protein-rich foods, including meat, poultry, fish, eggs, and dairy products.

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

Explanation

The cell was first coined by an English scientist Robert Hooke in the year 1665.

Later the cell theory was given by Matthias Schleiden and Theodor Schwann.

Explanation

Glucose, also called dextrose, one of a group of carbohydrates known as simple sugars

Explanation

Human respiration releases carbon dioxide and water as waste products

After the cells use oxygen to break down food for energy.

While breathing (ventilation) involves taking in oxygen

And releasing carbon dioxide through the lungs,

Cellular respiration is the chemical process within the cells

That breaks down glucose using oxygen to produce energy, CO2, and water. 

Explanation

• Plants absorb most of the water they need through their root hairs, which are small, thin extensions of the roots that increase the surface area for absorption.
• Root hairs are typically found in the rhizosphere, the region of soil surrounding the roots, and are responsible for absorbing water and nutrients from the soil.

Explanation

Lack of insulin causes diabetes.

Diabetes is a condition that happens when your blood sugar (glucose) is too high.

It develops when your pancreas doesn't make enough insulin.

Explanation

A hypothesis is a tentative statement or prediction that can be tested through scientific investigation.

It must be subjected to experimentation or observation to determine its validity — it is not always proved but always tested.

Explanation

Robert Hooke, a 17th-century philosopher and scientist.

He was the first to use the word "cell" to describe a basic unit of life.

Explanation

• Carbon dating is used to estimate the age of fossils.
• Those that are less than 60,000 years old.
• It is composed of organic materials like wood or leather.
