Answer: asexual reproduction is when an organism can reproduce without the need of another unlike sexual reproduction
Explanation: sexual reproduction happens when two organisms reproduce together giving the offspring 50% of each organisms DNA--
asexual reproductions is more like the organism replicating itself because the offspring has 100% of its DNA making it the exact same
Answer:
Option-C
Explanation:
Apoptosis is a genetically controlled process taking place in the multicellular organisms which is marked with the self-destruction called or programmed cell death.
During apoptosis various physiological and morphological changes take place in the cell such as fragmentation of nuclear DNA, nucleus, shrinkage of cell and mRNA decay.
Since apoptotic cell undergoes cell death which is genetically controlled or programmed by the genes, therefore, apoptosis is known as the programmed cell death.
Thus, Option-C is the correct answer.
In the Grand Canyon, there are clear horizontal layers of different rocks that provide information about where, when, and how they were deposited, long before the canyon was even carved.
Answer:
2. A change occurs in the environment.
4. Poorly adapted individuals have decreased survivorship.
1. Well-adapted individuals leave more offspring than do poorly adapted individuals.
3. Genetic frequencies within the population change.
Explanation:
The natural selection theory was developed by Darwin to explain how evolution occur within a population. The environment is in constant state of changes and always select for organisms that are better adapted to it.
Poorly adapted organisms gradually reduce from the population as a result of decreased survival while well-adapted individuals multiply and contribute more to successive generation.
Well-adapted individuals pass on the adaptive alleles to their offspring, eventually leading to a change in gene frequencies within the population.
Hence, the sequence of events is 2, 4, 1 and 3.
