- Why can’t males be the carriers of colour blindness?
Colour blindness is a s*x-linked recessive trait. And males only have X-chromosomes which makes them unable to be its carriers.
- What will be the cross result between a homozygous female and a haemophiliac male?

- How many base pairs of nucleotides are present in the human genome?
The human genome has 3.1647 billion (3 x 10⁹ bp) nucleotide base pairs and about 20,500 genes. The average gene size is 3000 base pairs.
- Which enzyme is known as the ‘chemical knife of DNA?’
Endonuclease enzymes are known as the ‘chemical knife of DNA.’ They cleave DNA at or near the specific recognition sequences (known as restriction sites).

- Why do most biologists think RNA was the first genetic material?
It is because the existence of ribozymes suggests that early cells could have used RNA to catalyse chemical reactions and transfer information.
- According to the chemical evolution theory, what is the sequence of origin of life?
Inorganic molecules→Organic molecules→Colloidal aggregates→Coacervates→Cell

- Why are DNA ligases called genetic gum?
DNA ligases join two individual fragments of double-stranded DNA by forming phosphodiester bonds between them. They help in sealing the DNA fragments. Therefore, they act as genetic gum or molecular glue.
- What is Recon?
Recon is the smallest unit of DNA that is capable of recombination
- What is Pathophysiology?
The term ‘Pathophysiology’ means the functional changes associated with or resulting from a disease or injury or a disease or syndrome.
- Does organic farming involve genetic engineering?
In organic farming, farmers use manure, biopesticides, biofertilizers, and biocontrol agents to increase crop production instead of artificial fertilisers and pesticides. It doesn’t include genetic engineering.

- What is the reason for the increase in global temperature?
The concentration of CO₂ is increasing day by day due to human activities. CO₂ can absorb heat radiation. Therefore, it increases global warming (or global temperature).
- How does PAN form?
PAN (Peroxyacetyl Nitrate) is formed due to the occurrence of the photochemical reactions between nitrogen oxides and hydrocarbons
3.What is net primary productivity (NPP)?
The total energy stored in the plant tissues after utilising some energy for their metabolic activities through respiration is called net primary productivity (NPP).
- If all the world’s plants die, all the animals will also die. Give a reason.
It happens because all the consumers (animals) depend on producers (plants) for their food.

- What do you mean by eroded soil?
The topsoil is fertile as it contains organic matter and nutrients. When soil erosion occurs, the topsoil is removed. As a result, due to the absence of plant nutrients, the productivity of the soil is reduced. Such soil is called eroded soil.
- What is the threat to wildlife?
Habitat destruction is most dangerous to wildlife because the habitat provides a suitable atmosphere necessary for survival.
- When did the wildlife protection act pass?
The wildlife protection act was passed in 1972.
- What is the main cause of the Bhopal Gas Tragedy?
It was one of the world’s worst environmental and industrial disasters. It happened not due to the side effects of radioactive products but because of the leakage of phosgene and methyl isocyanate gas.
