Answer:
According to Darwin's theory of evolution, new species evolved as a result of natural selection.
Explanation:
- Darwin proposed that speciation could readily occur through the prolonged action of Natural selection.
- Natural selection allows the 'survival of the fittest' i.e. a more fit organism will have a better chance of survival than the less fit one.
- The result of Natural selection could be positive,negative or balancing.
- Evolutionary process in which the genetic changes confer a higher fitness to increase frequency of the organism over time in population is called positive selection.
- Evolutionary process in which genetic changes decreases the organism's fitness resulting in its disappearance from the population is called Negative selection.
- It may happen that a mutation benefits hetero-zygotes but not homo-zygotes and alleles maintain a intermediate frequency in population.This evolutionary process is called balancing selection.
Answer:
Explanation:
The type of RNA that contains the information for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm. Translation, the second step in getting from a gene to a protein, takes place in the cytoplasm.
Plants perform cytokinesis differently than animals because plant cytokinesis takes place during interphase but animal cytokinesis takes place in cell division.
> Unlike animal cells, plant cells have a cell wall which needs to be divide or split up.<span>
>Mitosis and cytokinesis are two different things; mitosis is the division of the components of the nucleus, whereas cytokinesis is the division of the
cytoplasm and its constituents.
Thus, the answer is letter A.</span>
