An organism's genome is analyzed and found to contain 18% guanine. What percentage of that organism's DNA is adenine?
Oxana [17]

Answer:

32%

Explanation:

According to Chargaff in his complementary base pairing rule, he stated that the proportion of purine and pyrimidine bases is equal to 100%

That is, A + T + G + C = 100%

Where A=T and G=C i.e the proportion of each base pair is equal.

Hence, if the Guanine content is 18%, it means the Cytosine content of that DNA molecule must also be 18%. Therefore:

18 + 18 + A + T = 100

A + T = 100 - 36

A + T = 64

If the sum proportion of Adenine and Thymine is 64% and each must contain equal proportions, A or T = 64/2 = 32

Hence, Adenine contains 32%, likewise Thymine.

Why are negative feedback loops used to control body homeostasis? <br><br> (Short answer)
liberstina [14]

Answer:

Homeostasis is defined as the state of body in which body maintains several chemical and physical changes inside the body affected by external factors.

Negative feedback loop includes a sensor, stimulus, control center, and effector which is used to control homeostasis.

A negative feedback loop is a reaction that reduce an excessive response and maintain the functions within the normal range. for example: if temperature and blood glucose level increases in the body, negative feedback loops control both the variables and maintain homeostasis.  

Hence, negative feedback loops used to control body homeostasis.

Answer: Allopatric Speciation

Explanation:

Allopatric speciation occurs when new distinct species are formed due to the separation of a specie into two separate groups. These two groups are kept away from each other.

In allopatric speciation there is no exchange of genes between the two separate groups.

Allopatric speciation can also be known as geographical speciation.
