Answer: Genetic variation within a species can result from a few different sources. Mutations, the changes in the sequences of genes in DNA, are one source of genetic variation. ... As a result, the tree-colored moths are more likely to survive, reproduce, and pass on their genes.
Explanation:
Answer:
Yes, if the mother swan pushes a third baby swan in front of her, work being done on the third baby.
Explanation:
Work is defined as the displacement covers by the body in the direction of the applied force. Work will be done on the body if a person pulls or pushes the other body or object. So according to the definition of work, if the mother swan pushes the third baby and the baby covers some distance away from the mother swan so we can say that work being done on the third baby.
Answer: option D) Cells can function equally as well at all pH's because enzymes are effective at all pH's.
Explanation:
Studies in biology have demonstrated that:
- All living tissues have different pH (stomach is acidic, it has a pH below 7; saliva is alkaline, it has pH above 7 etc)
- All living tissues has a stable physiological temperature of 37°c
- All living tissues contain enzymes such as Catalase
Thus, based on the information given, we can infer that all cells can function equally as well at all pH's (whether acidic, neutral or alkaline) because enzymes are also effective at all pH's.
