Sugar , phosphate , and one of the 4 bases (adenine ,guanine,cytosine,thymine)
That is a HYPOTHESES because it says "May Cause"
Active transport requires energy, whereas passive doesn't.
Both Endocytosis and Exocytosis are transports that require energy from the cell in order to transport particles. Therefore, they're forms of active transport.
The two ultimate sources of energy for all living things on earth is sun light and certain rich compounds like chemotropes.
<u>ANSWER:</u>
'Adaptations enhance survival' is true about all adaptions.
<u>EXPLANATION:</u>
- Adaptation is a mechanism in organisms that allows them to adjust with the changes in their current environment or to adapt to their new environment.
- Darwin explained this as a concept of a natural selection process where organisms are susceptible to the variations with the environmental changes.
- These variations which are associated with greater survival and reproductive success are retained in the progeny. This phenomenon is known as Darwinian fitness.
