The Miami blue butterfly and the Florida scrub jay are both endemic to the State of Florida. The Miami blue butterfly is a critically endangered species while the Florida scrub jay is a threatened specie. Both of their numbers are <span>dwindling and efforts are being made to protect their continue existence.
Hope this helps!</span>
Answer:
DNA replication is semi-conservative because each helix that is created contains one strand from the helix from which it was copied. The replication of one helix results in two daughter helices each of which contains one of the original parental helical strands.
A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. ... Mutations can also occur as the result of exposure to environmental factors such as smoking, sunlight and radiation.

A genetic mutation is a permanent modification in the DNA sequence of a gene to what is found in most people.
The complete question is as follows:
1. What does a surface area/volume ratio of 6:1 mean for the cell’s ability to get the materials it needs that move across its surface?
2. What does a surface area/volume ratio of 3:1 mean for a cell’s ability to get materials across its membrane, compared to the cell with a ratio of 6:1?
Answer:
1 . Surface area to volume ratio = 3 : 1
surface area= 3 cm³ or (l = 1 cm) (1 cm x 1 cm x 3) (W = 3)
volume= 1 cm³ (1cm x 1cm x 1cm)
2. Surface area to volume ratio = 6 : 1
surface area= 6 cm³ or (1 cm x 1 cm x 6 ) (w= 6)
volume= 1 cm³
Diffusion increases with the increase in surface area to volume ratio through the semi-permeable membrane of the cell membrane that allows substances to move into the cytoplasm
<h2>Jean Baptiste Lamarck</h2>
Explanation:
Jean Baptiste Lamarck (1744-1829) was an important French naturalist. He was one of the first scientists to propose that species change over time.
Jean Baptiste Lamarck published his theory of evolution in the book <em>Philosophie zoologique </em>called the theory of use and disuse or the inheritance of acquired characteristic. According to this theory, ecological conditions in which an organism lives cause it to have certain needs. These needs are met by modification of old organs or by production of new rudimentary organs.The continuous use of the rudimentary structures allows them to increase in size and disuse causes that organ to degenerate. These changes become fix and become inheritable.
