Ivan

For 2,000 mice living in a field,  the per capita growth rate  is mathematically given as

NT=0.4

<h3>What is the per capita growth rate (rmax) of mice over a month?</h3>

Where

DT=200/2000

DT=0.1

In conclusion, per capita growth rate

NT=0.5-0.1

NT=0.4

A section of DNA encodes a gene for an enzyme involved in cellular metabolism. If a mutation event occurs that results in the de
Lady_Fox [76]

Answer:

The correct answer would be C. The protein synthesized will contain many erroneous amino acids since the loss of one base will shift the reading of the encoded base sequence.

Deletion mutation that does not occur in the multiple of three bases can results in frame-shift mutation.

It changes the reading frame of nucleotide in DNA. Thus, the reading frame of codons in mRNA would also change.

Consequently, the sequence of amino acids in a polypeptide chain would change or alter. Thus, a protein would contain many erroneous amino acids.

An example of the same is shown below in the image.

4A. The chromosome theory of inheritance states that chromosomes are the main carriers of the genetic factors responsible for inheritance.

B. Body cells have two sets of chromosomes while sex cells have one set. Therefore, when two sex cells meet, they form an embryo with two copies of each chromosomes thereby producing a body cell with the exact number of chromosomes. In essence, meiosis maintains the right number of chromosomes of body cells by creating half the number of chromosomes of sex cells.
