Answer:
Molluscs have more varied forms than any other animal phylum. They include snails, slugs and other gastropods; clams and other bivalves; squids and other cephalopods; and other lesser-known but similarly distinctive subgroups. Although it is impossible to know the subjective experience of another animal with certainty, the balance of the evidence suggests that most invertebrates do not feel pain. The evidence is most robust for insects, and, for these animals, the consensus is that they do not feel pain. In general, mollusks have 3 body regions: a head, a visceral mass, and a "foot." The head contains the sense organs and "brain," while the visceral mass contains the internal organs. Mollusks usually have a shell (although some do not). Mollusks also have an extension of the body wall called the mantle.
Explanation:
Answer:
Natural selection leads to evolution due to the way reproduction works. In the example of European moths during the industrial revolution, we can see this clearly. When the industrial revolution was going, there was more pollution, hence darkening the skies and leaving ash. Moths, which before were white with occasional black spots dominated the area until pollution effected their environment. Whiter moths were eaten by bird who could easily see them against the black trees and skies. These moths could no longer reproduce, they were dead. Moths with more black could survive longer to reproduce because they were harder to see. As time went along, the moths turned mostly black, showing an example of evolution.
Answer:
During transcription, only one strand of DNA is usually copied. This is called the template strand, and the RNA molecules produced are single-stranded messenger RNAs (mRNAs). The DNA strand that would correspond to the mRNA is called the coding or sense strand
Explanation:
Answer:
Plant A listens to classical music for three hours each day
Explanation:
- Music affect plant growth of plants through the vibrations that it creates to the sound waves.Classical music causes more pressure to the sound waves causing vigorous vibrations which is picked up by the plants speeding up the protoplasmic movement in the cells.
- The vibrations causes movement of the plant cells which speed up growth of the plants by stimulating the plants to produce more nutrients enabling them to germinate having more leaves,greater in size and other improved characteristics which means the plant's genetic chromosomes were changed.
- Also in the soil is able to produce good fungi and bacteria encouraging better root development due to healthy vines resulting to vigorous growth and better fruit.
- Moreover the plants are able to receive special attention and care from the farmer thus enhancing faster growth.
