Answer:
it is two answers (A and d)
Explanation:
If we keep the same theory of light today we wouldn't be advanced as we are now so yes the old theory had to get updated or plain or replaced with a newer one, D is also correct because if you repeat something you will find out new things from the first time you tried it out.
Answer:
C) Population bottleneck reduced genetic diversity, as the gene pool of the 30,000 elephant seals resulted from the few alleles present in the 20 bottleneck survivors.
Explanation:
<u>The correct answer would be that population bottleneck reduced genetic diversity, as the gene pool of the 30,000 elephant seals resulted from the few alleles present in the 20 bottleneck survivors.</u>
A sudden decrease in the population of an organism as a result of disaster or any other factor leads to a population bottleneck - a decrease in the genetic variability of the population.
<em>The decrease in the available number of alleles in the population limits the amount of genes that natural selection can influence. Hence, as the population keeps increasing, the genetic diversity of the entire population rarely changes because the few alleles present in the population keep recombining.</em>
The correct option is C.
<span>B. areas of high population density will have greater needs and deplete resources available</span>
Answer:
In ecosystems, matter and energy are transferred from one form to another. ... Nutrients and living matter are passed from producers to consumers, then broken down by decomposers.
Explanation:
Which in turn leads to movement in the crust
