Explanation:
Incinerators are not helpful in reducing pollution as they produce a lot of ash and smoke so it increases the air pollution by burning of waste.
Solar and wind energy are the clean source of energies replacing the fuels. Catalytic converters reduce the air pollution from the exhaust fumes of vehicles.

Answer:
When the bladder is completely deflated, the fish has minimum volume and sinks to the ocean floor
Answer:
50%
Explanation:
The allele for black fur (B) is dominant to the allele for brown fur (b).
- BB or Bb = black fur
- bb = brown fur
A male homozygous black mouse (BB) is crossed with a female brown mouse (bb). The male parent only produces<em> B</em> gametes and the female parent only produces <em>b</em> gametes. The F1 offspring will be 100% heterozygous Bb.
The F1 individuals will produce <em>B</em> and <em>b</em> gametes. If we cross the F1 individuals to each other (Bb x Bb), we'll get the following F2 offspring:
- 25% BB homozygous dominant
- 50% Bb heterozygous
- 25% bb homozygous recessive
So 50% of the F2 will be homozygous (BB or bb).
Answer:
Remove Na + from the extracellular compartment and assess the early current under new conditions
Explanation:
Na+ is a critical ion that influences the action potential in nerve cells. During the transmission of an impulse, the cell membrane is open so ions can flow through it, i.e., positively charged ions such as sodium ions (Na +) move within the cell, while negatively charged ions move outside the cell. This process produces a change in the action potential by rapidly increasing the positive charge in the nerve fiber, being thus the impulse propagated when this charge reaches +40 mv. In consequence, the effects of Na + on the single-channel current can be analyzed by removing positive ions and determining the change in the reversal potential of this channel.
The 2 phases are Prophase and Telophase
