Biology Answers (These are just a hints to write the answers)

1. (b) Deoxyribose sugar, a nitrogen base and a phosphate

2. (d) Abscisic acid

3. (c) (i), (iv), (iii), (ii)

4. (a) Help in inserting the active gene into stem cells.

5. Advantages of technological possibilities in environmental conservation:

• (a) Bioremediation: It uses microorganisms to naturally break down and remove environmental pollutants (like oil spills or heavy metals) from soil and water, making it a cost-effective and eco-friendly clean-up method.

• (b) Cryopreservation: It allows for the long-term preservation of biological materials (like seeds, tissues, sperm, or eggs) at extremely low temperatures (using liquid nitrogen). This is crucial for conserving the biodiversity of endangered or rare species for future use.

6. (A) Synapse Structure:

• (a) The chemical labelled as 'X' is a Neurotransmitter (such as Acetylcholine).

• (b) Role in one-way transmission: Neurotransmitters are stored and released only from the synaptic vesicles of the presynaptic membrane (axon terminal), and the specific receptors that bind to them are located exclusively on the postsynaptic membrane (dendrite). This structural arrangement ensures that nerve impulses can only flow in one direction across the synapse.

OR

6. (B) Autonomic Nervous System:

• (a) The Sympathetic Nervous System controls these actions (it triggers the "fight or flight" response).

• (b) Two other actions controlled by this system: 1. Dilation of pupils (to let in more light).

  2. Dilation of the bronchi (to increase oxygen intake).

  (Other acceptable answers include decreased saliva production, stimulation of sweat glands, or release of glucose from the liver).

7. Antibiotics and Pathogens:

• (a) Antibiotics are used to destroy Bacteria.

• (b) Major concern of stopping early: Stopping an antibiotic course too early may leave some bacteria alive. These surviving bacteria can mutate and develop antibiotic resistance, meaning the same antibiotic will no longer be effective against them in the future, making subsequent infections much harder to treat.
