Explain how natural selection might be a mechanism of evolution

Biology
1 answer:
7nadin3 [17]3 years ago
5 0
Natural selection is a process in which the best adapted individual survives. In Darwin's studies on the Galapagos islands, he found 4 different bird species on 4 different islands. The islands were not that far from each other but it still took a while to get from one to the other. He discovered that the species were different because of their environment. Therefore, each specie was adapted to its environment. On the other hand, evolution is a long term process that adapts an individual to it's habitat. Therefore, by eliminating all individuals who are not able to survive, we are left with the ones who were able to live and reproduce and have children who will have changed a bit and will continue changing until the specie is completly adapted. That is the link between natural selection and evolution.

Suppose a BB female mouse mates with a Bb male mouse. Which of the following represents the probabilities of each genotype occur
Aleksandr [31]

Answer:

As the offspring inherits one allele from each parent, it will obtain only the B allele from the female mouse and either the B or b allele from the male mouse. Hence possible offspring genotypes are BB or Bb with 0.50 probability each (each probability of either genotypes being present in the offspring).

DNA replication is Group of answer choices conservative. a one-step process. semi-conservative. not carried out by enzymes. not
Alex787 [66]

Answer:

The correct answer is: semi-conservative.

Explanation:

DNA replication is an important process in which the DNA is duplicated before cell division so each daughter cell can have a copy of genetic material.

DNA replication is <u>semi-conservative because one strand of DNA is new and the other one is the old strand</u>. To replicate itself, the DNA double helix is opened, and then each strand serves as a model for the new strands.

DNA replication is <u>not a one-step process</u>, as it takes several complicated steps in which <u>lots on enzymes participate</u> (like DNA polymerase and DNA helicase).

DNA replication is <u>also carried by prokaryotic cells</u>, though it's a much simpler process.
