to give birth to youg one
Answer A seems like the best choice for this question. Just think about some of the synonyms for therefore—”hence,” “consequently,” and “thus.” Because the adverb therefore often plays the role of a conjunction, it's sometimes called a conjunctive adverb.
B isn’t the correct answer to this question because you use “On the other hand” to introduce two contrasting points, facts, or ways of looking at something.
C isn’t the correct answer because we are not comparing or contrasting anything in this sentence.
D isn’t the correct answer because “Especially” is used in a formal sentence example: She can't be sure she will win, especially at this early stage of the campaign.
Recombination
: the process occurring in Meiosis I, in which offspring are able to obtain unique traits resulting in an array of different phenotypes (physical appearances).
Prophase I,
the homologous chromosomes line up in the middle of the cell and exchange segments of alleles, and then lining up in the cell in a NON-uniform way.... therefore resulting in genetically unique offsprings rather than identitical.
Mutations are result of evolutionary factors. They create genetic diversity that helps species adjust to different climates, behaviours and foods. Mutations that occur in a fit indivual can result in offspring that are genetically more successful in adjustments to different climates, foods, and environments.
All in all Recombination results in unique looking indivuals, whereas mutations result in greater survival chances of a species.
This ensures that the experimenter can be certain that the variable they are testing is what causes a pattern in the data if there is a pattern.
