Answer:
Plasma carries water, salts and enzymes.
Explanation:
The main role of plasma is to take nutrients, hormones, and proteins to the parts of the body that need it. Cells also put their waste products into the plasma. The plasma then helps remove this waste from the body.
They damage proteins and DNA.
Explanation:
Aldehydes damage proteins and DNA of microbial organisms. They typically inhibits the growth of microbial organisms by causing alteration to proteins and DNA.
- They cause damage to proteins ans are used as disinfectants.
- The aldehydes generally cross link functional groups in proteins and short changes their structures.
- Formalin is one example that is used to arrest bacteria growth and it is an aldehyde.

Answer:
1. Isotonic
2. Hypotonic
3. hypertonic
4. hypotonic
5. Hypertonic
6. Hypotonic
Explanation:
Tonicity refers to the amount of the solute concentration dissolved in the solution which determines the direction of the diffusion across the semipermeable membrane.
There are three types of tonic solutions formed on the basis of solute concentration which are:
1. Isotonic solution: When the solute concentration is the same across both the sides of the semipermeable membrane. When a cell is placed in isotonic solution it remains in the same state as no movement of water is observed as in option 1.
2. Hypertonic solution: The solution which contains a high amount of solute and a low amount of water. When the cell is placed in this solution the cell shrivels as the water movement is observed from the cell to outside down the concentration gradient like in option-3 and 5.
3. Hypotonic solution: The solution which contains the low amount of solute and high amount of water, when a cell is kept in the hypotonic solution the cell swell and could become flaccid if is a plant cell as in option 2, 4 and 6.

Answer:
wildfires
Explanation:
Wildfire is a part of nature. It plays a key role in shaping ecosystems by serving as an agent of renewal and change. But fire can be deadly, destroying homes, wildlife habitat and timber, and polluting the air with emissions harmful to human health.
