Answer:
Reproductive success of an individual is measured in term of its genetic contribution to the future generation as compared to that of other individuals of the same population.
Explanation:
Natural selection is the ability of some organisms to survive better and reproduce more due to the presence of some beneficial genetic traits. These individuals are able to leave more progeny as compared to the other individuals of the same population that lack those genetic traits. Therefore, reproductive success represents the ability of an organism to leave more progeny to contribute more to the gene pool of future generations.
Answer:
See the answer below
Explanation:
<em>Replication is a process involving the production of daughter copy by DNA. Transcription, on the other hand, is a process during which the coding strand of DNA is used as a template for the production of mRNA - messenger RNA.</em>
During DNA replication, <u>Adenine is paired with Thymine while Guanine is paired with Cytosine</u>. During transcription, <u>Adenine's pairing is replaced with </u><u>Uracil</u> while Guanine/Cytosine pairing remains the same.
hence, the main difference between the base-pairing during both processes is the replacement of Thymine with Uracil during transcription.

Answer:
B. Once the specimen is in focus under a low power lens, the microscope can be switched to a higher power lens without moving the stage and the image will be in or nearly in focus no matter what lens is used.
Explanation:
As a result of diffusion the concentration of many types of substance eventually become balanced on both sides of the membrane.
b.)eventually becomes balanced on both side of a membrane.
<u>Explanation:</u>
Diffusion is the process by which substances move from a region of high concentration to low concentration. It is crucial in several biological processes and is a form of passive transport. Since the movement is down the concentration gradient, passive transport doesn’t require any energy.
When there exists a difference in concentration between the substances inside and outside a membrane the diffusion of substances through the membrane begins. The diffusion continues until the concentration of substances inside and outside of the membrane becomes balanced.
