Answer: Sexual reproduction is advantageous over asexual reproduction because it reduces the rate of mutation accumulation.
New Zealand mud snails reproduce through asexual and sexual modes of reproduction. Asexual reproduction allows these organisms to reproduce more number of offsprings. Asexual reproduction advantageous as these organisms faces natural disaster conditions like tide, drought results in the decrease in the population. Therefore, does not get mate to undergo sexual reproduction. Sexual reproduction in these snails results in genetic variation in offsprings. Sexual reproduction results in increase in mutation rate in the genetic material being passed to offsprings because of resorting of genetic material being distributed from parent to offspring. This will result in genetic variations. Hence, parent will be different from offsprings. In asexual reproduction offsprings are the clones of parents as there is no resorting of genetic material takes place.
Answer:
DNA never leaves the nucleus; RNA is in the nucleus and in the cytoplasm.
Explanation:
DNA and RNA differ from each other with respect to their structure, function, and location. DNA is always present in the nucleus and never leaves the nucleus.
DNA replication and transcription also occur in the nucleus to form DNA and RNA respectively.
On the other hand, RNA is present in both the nucleus and cytoplasm. The mRNA leaves the nucleus and enters the cytoplasm to serve as a template in protein synthesis. The rRNA and tRNA are also present in the cytoplasm.
The cell membrane is what surrounds a cell and allows water to pass through.
Answer:
The red should indicate warm weather, while the blue should indicate cool weather.

Electrical energy
Explanation:
Electrical energy is the energy created by the flow of electrons through conductors.
The movement of electrons in conductor generates electricity.
- Electronic movement in electrochemical cells also produces electrical energy.
- Current flows in opposite direction to the flow of electrons.
- The electromotive force of cell provides the driving force for the current in a cell.
