Biology Questions

Deep fried foods are carcinogenic because they are rich in fats.

Type 2 diabetes is the most common form of diabetes.

• If you have type 1 diabetes your body does not release insulin.

• If you have type 2 diabetes your body does not use insulin properly.

DNA is made of nucleotides. And these Nucleotides are made of a pentose sugar deoxyribose, a phosphate, and a nitrogen-containing bases.

Hence, the given statement 'Nucleotides are made of a pentose only' is FALSE.

Phosphorescence is a phenomenon associated with an algal division called euglenophytes. 

Phosphorescence is a phenomenon when an object is capable of releasing photons of light at a longer wavelength in response to absorbing light of a shorter wavelength. The object releasing the light only releases the light after some time has passed since it absorbed the light of a short wavelength.

Euglenophytes are single-celled plant-like protists that have no cell wall.

Salts and sugars work to preserve foods by creating a Hypertonic environment.

We know that the circulatory system of our body is a loop. The Heart is the pump, the arteries and their smaller branches (arterioles) carry oxygen rich blood all through your body tissues from the heart and the veins and their smaller branches (venules) carry oxygen depleted blood and waste products back to the heart from all the body parts.

Smooth Endoplasmic Reticulumdoes not contain ribosomes on its surface for which it is regarded as smooth. So, proteins cannotbe synthesised by SER provided protein synthesis is the primary task of ribosomes.

A RNA copy of a DNA gene is called as messenger RNA or mRNA. mRna is used in translation because information is translated from one language (nucleotides) into another (amino acids).

Hence, mRNA is used to transfer genetic information by a cell.
