Answer:
(1) as organic molecules in living and dead organisms found in the biosphere; (2) as the gas carbon dioxide in the atmosphere
Explanation:
The options for this question are:
- Requires genetic variation
- Results in descent with modification
- Involves differential reproductive success
- All of the above
Answer:
<u><em>The correct option is d) All of the above</em></u>
Explanation:
The theory of natural selection explains that genetic variations occur in organisms of a species. Those organisms which are better adapted to live in an environment are able to survive and pass on their characteristics to their offsprings, hence descent with modification. Through this phenomenon, evolution takes place with the passage of time. Natural selection favours survival of the fittest. Hence, all of the above statements are true.
First thing to remember is that interphase is a stage associated with replication of DNA, and growth.
Once meiosis starts, the purpose is to produce a haploid gamete. So there is no further need of replication or growth.
False- interneurons pass electrical impulses from a sensory neuron to a motor neuron (it connects these neurons)
The main purpose of hemoglobin is the transport of OXYGEN and CARBON DIOXIDE
