Explanation

The name of the fluid that fills the mitochondria is matrix.

The mitochondria have an outer membrane, an inner membrane, in the inner membrane, a gel-like fluid is present which is called a matrix.

A matrix is viscous.

Explanation

Human teeth have two sets of teeth during their life i.e, one temporary set of milk and one permanent set.

Additional information:

The first set, deciduous teeth, also called "primary teeth"

It eventually contains 20 teeth.

They usually grow in by the age of 2.

The second set is called permanent teeth.

These are the teeth that grow between the ages of 6 and 12.

You start with 20 primary teeth

and end with 32 permanent teeth,

including the four wisdom teeth.

Explanation

 Centrioles are composed of nine triplets of microtubules arranged in a cylindrical structure.

Each triplet consists of three microtubules arranged in a cylindrical fashion.

So, overall, a centriole consists of a total of 27 microtubules organized into nine triplets.

Explanation

We select 70 percent because:

- On average, the human body is made up of about 60–70% water.

- This percentage varies by age, gender, and body composition:

  - Infants have up to 75% water.

  - Adult men ≈ 60–65%

  - Adult women ≈ 50–60%

- Water is found in cells, blood, and other body fluids, and is essential for processes like:

  - Temperature regulation

  - Nutrient transport

  - Waste removal

  - Joint lubrication

Therefore, 70% is the most accurate and commonly accepted average.

Explanation

Epistemology is the theory of knowledge

It deals with the nature, origin, and scope of knowledge.

Explanation

A fasting blood sugar level of 99 mg/dL or lower is normal, 100 to 125 mg/dL indicates you have prediabetes, and 126 mg/dL or higher indicates you have diabetes

Explanation

The primary function of the digestive system is to:

Ingest food: Food is taken into the body through the mouth.

Break down food: Mechanical and chemical processes break down food into smaller molecules that can be absorbed.

Absorb nutrients: The small intestine absorbs nutrients such as carbohydrates, proteins, fats, vitamins, and minerals into the bloodstream.

Eliminate waste: Undigested food and waste products are removed from the body through defecation.

Explanation

The most likely genotypes of the parents of a baby girl with hemophilia are that the mother is a carrier and the father is a hemophiliac.. 

Hemophilia is X-linked recessive:

This means the gene for hemophilia is located on the X chromosome, and a female needs both copies of the recessive gene to express the disorder. 

Male genotype:

Males have only one X chromosome, so if they inherit the hemophilia gene, they will have the disease. 

Female genotype:

Females have two X chromosomes. If they inherit one copy of the hemophilia gene and one copy of the normal gene, they will be carriers but won't have the disease. 

Explanation

Nickel and Iron present in the inner core of the Earth are together known as NiFe.

The extreme pressure exerted on the inner core by the rocks of the layers lying above causes the NiFe to be in a solid state.

Explanation

Solar energy is radiated from the sun in the form of electromagnetic waves of shorter wavelength of 0.2 to 0.4 micrometers.

Out of all the solar energy radiations reaching the earth's atmosphere,

8% is ultraviolet radiation,

40% is visible range light 

46% is by infrared radiation.
