A scientist is extracting the DNA of a multicellular organism. He finds that 20% of the strands bases are Thymine. Based on Chargaff's rule, what percentage of the
strands bases would be Adenine?
A. 20%
B. 70%
C. 40%
D. 60%
Answer:
A. 20%
Explanation:
A DNA molecule consists of four nucleotides viz: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). According to Chargaff in his complementary base pairing rule, these nucleotides pair with one another in such a way that A bonds to T, while G bonds to C.
Based on Chargaff's rule, the amount of Adenine in the DNA is equal to the amount of Thymine while the amount of Guanine is equal to that of Cytosine i.e. A=T, G=C.
A + T + G + C = 100%
Hence, in this question, a scientist finds that 20% of the strands bases are Thymine. This means that the amount of Thymine in that DNA will also be 20%. S
Since A=T = 20% in accordance to Chargaff rule.

The structure labeled "A" open and close the sites where the gases, carbon dioxide and oxygen, are exchanged during photosynthesis. What is the structure labeled A?
The structure A in the question seems missing but the given answer is based on the description given in the question.
Answer:
The gaseous exchange of carbon dioxide(CO2) and oxygen(O2) occurs through small, regulated openings called stomata during photosynthesis.
Therefore the Structure A is Stomata

1. How much force accelerate a bicycle and rider with mass 60 kg at 1.5 m/s?
Answer:
Force, F = 90 N
Explanation:
Given that,
Mass of the bicycle and rider, m = 60 kg
Acceleration of the bicycle and rider, a = 1.5 m/s²
We need to find the force acting on the bicycle and rider to accelerate. Let it is F. Its force is given by :
F = ma
F = 60 kg × 1.5 m/s²
F = 90 N
So, the force acting on the bicycle and rider is 90 N.

Erythrocytes (red blood cells)have no nucleus, mitochondria, orother organelles at maturity. Theseorganelles are ejected when the RBCenters the bloodstream, or shortlythereafter. Should this still beconsidered a cell? What will be theeffect of having no nucleus? In thesecells, the lack of mitochondria is anadvantage. Why?
Answer:
Erythrocytes are not considered true cells, because of their lack of a nucleus. The effect of having no nucleus makes their self-reproduction impossible, and the absence of mitochondria is a disadvantage because they have to obtain energy by alternative reactions.
Explanation:
Erythrocytes, or red blood cells, are the structure in charge of transporting gases in the blood. When these cells are mature, they have already lost their nucleus —in order to have space to house the hemoglobin molecule— which prevents mature red blood cells from being able to reproduce.
Additionally, red blood cells do not have mitochondria —the main energy generator in eukaryotic cells— so in order to obtain energy they need to perform lactic fermentation, with a lower enegetic yield, which may be a disadvantage, but sufficient for this structure to perform its function.

There are two forms of diabetes. Type II diabetes is also known as late-onset diabetes because it typically affects adults. Consider the following information about Type II diabetes:
Studies have shown that the lifetime risk for developing Type II diabetes is 40% for individuals who have one parent with Type II diabetes.
If a person has two parents with Type II diabetes their risk rises to 70%
Other factors that affect your risk for Type II diabetes include obesity, a sedentary lifestyle (not moving around much), a small or large birth weight, and stress.
Use the information above to answer the question: Is your risk of having Type II diabetes due to your genes, or due to the influence of the environment on your genes (epigenetics), or both?
Answer:
Both
Explanation:
As explained in the passage wether your mom or dad or both have had type ll diabetes in the past determines your risk of having it as well which is part of your genes. But also the influence of the environment on your gene is also a cause to type ll diabetes . Some people would rather stay inside rather than get exercise or some people would rather eat candy or sweets for breakfast or dinner all these things are causes of type ll diabetes which they are caused by the influence big the environment on your genes.
