If 22% of a DNA sample is made up of cytosine, C, what percentage of the sample is made up of adenine,
A?
Answer:
28% of Adenine
Explanation:
Chargaff's Rule states that A = T and C = G
Because of that, the sample must have the equation:
A + C = T + G
G must have the same amount as C so,
A + .22 = T + .22
Both sides of the equation must equal each other by .50, so .50 - .22 = .28
.28 x 100 = 28%
If 22% of a DNA sample is made up of cytosine, C, the percentage of the sample is made up of adenine, A is 28%
What is DNA?The DNA sequence is the sequence or pairing of DNA bases. RNA and DNA both are genetic materials and both are made up of nucleic acids made up of deoxyribose acid and iron is made up of ribonucleic acid.
DNA and RNA both contain four bases that are joined with hydrogen bond RNA contain uracil in the place of thymine and DNA contain timing all other bases are the same.
Chargaff's Rule states that A = T and C = G
Because of that, the sample must have the equation:
A + C = T + G
G must have the same amount as C so,
A + .22 = T + .22

Answer:
a i think
Explanation:
The following statements about niches are false: The crow is a quite adaptable organism and has a broad niche, which is option C, as the niche is not a broad place but a place where the individual spends most of the time living and reproducing.
What exactly are "niches"?A niche is the place that an organism plays in its environment, including the physical space it occupies and the resources it uses, and it is the way that an organism interacts with its environment and with other organisms, whereas niches can be occupied by many different types of organisms, and in some cases, different organisms may even occupy the same niche at the same time, which is known as niche overlap.

People who have leukemia, a cancer that affects white blood cells, are often given Cytarabine. This drug inhibits the synthesis of DNA. Which phase of the cell cycle is most affected by Cytarabine?
A
Interphase
B
Cytokinesis
C
Prophase
D
Anaphase
Answer:
I think interphase because fna synthesis happens within the s-phase of the cell cylce and 5he s phase is suring interphase and not mitosis
The phase of the cell cycle which is most affected by Cytarabine is the Interphase. Thus, the correct option is A.
What is the cell cycle?The cell cycle may be defined as the entire sequence of events happening from the end of one nuclear division to the beginning of the next. The entire cell cycle can be divided into two phases.
The InterphaseThe M-phase (division phase).As per the question, the drug Cytarabine inhibits the synthesis of DNA, it definitely inhibits the interphase of the cell cycle. This is because the synthesis of DNA occurs in the S-phase of the cell cycle which is a substage of the interphase.
Therefore, the interphase of the cell cycle must be affected by the drug Cytarabine. Thus, the correct option for this question is A.

You will build a simulation of a population using the same elements as the simulation pictured here and show how
the traits in this population change in years 5 and 10.
- Trait A
- Trait B
- Trait
1 circle = 50 organisms
Start off with 2,500 plants of which 50% have medium-tip leaves, 25% have wide-tip leaves, and 25% have drip-tip
leaves. Each circle in your simulation will represent 125 organisms. Calculate how many circles you need for each
trait, and then create your simulation. Be sure to include a key that states the color coding for each trait.
According to the concepts of percentage and proportions, we can make the simulation with 20 circles, each of them representing 125 plants. Traits A = 10 circles. Trait B = 5 circles. Trait C = 5 circles.
To solve this problem, we need to know two concepts, percentage and proportion.
What is a percentage?A percentage can be defined as a fraction or a part of 100. It is denominated as percent (symbol %).
100 refers to the number of parts into which the unit has been divided.
So, X% means that for every 100 parts, X parts are of our interest. Or, that we are interested in X fraction from a total of 100 parts.
What is a proportion?A proportion is the equal relationship between two determined ratios or quantities.
In the exposed example we need to represent this population of 2500 plants with circles.
We know that,
Each circle represents 125 plants50% of the population have medium-tip leaves, 25% have wide-tip leaves, and 25% have drip-tip leaves .So here, our unit is the population. We can say that our population of 2500 plants is composed by 100 subunits or parts.
2500 plants ------------ 100 parts
So now we will calculate how many plants are represented by the 50% and 25% of the population.
If 100% of the population equals 2500 plants, how many plants are 50% of the population and 25% of the population.
100% -------------------- 2500 plants
50% -------------------- X = (50% x 2500 plants) / 100% = 1250 plants.
25% ---------------------X = (25% x 2500 plants) / 100% = 625 plants
Now we know that from the total of 2500 (100%) plants,
1250 (50%) have medium-tip leaves, 625 (25%) have wide-tip leaves, and 625 (25%) have drip-tip leaves.Finally, we need to calculate how many circles represent these numbers. So, we know that 1 circle equals 125 plants. The question is, how many circles represent 2500, 1250 and 625 plants.
125 plants ----------------- 1 circle
2500 plants -------------X = (1 circle x 2500 plants) / 125 plants= 20 circles.
1250 plants --------------X = (1 circle x 1250 plants) / 125 plants = 10 circles.
625 plants ---------------X = (1 circle x 625 plants) / 125 plants = 5 circles.
So, our simulation must have 20 circles, from which
10 circles represent medium-tip leaved plants (Trait A), 5 circles represent wide-tip leaved plants (Trait B), and the remaining 5 circles represent drip-tip leaved plants (Trait C).In the attached files you will find the image.

Kai has a see-through glass tank with air, plants, and animals that eat
those plants. He sealed the tank so no material can get into or out of it,
but light can get in when the tank is not covered.
The light for the tank has been on all day, and Kai measured the carbon
in the air and found that it is decreasing. How is carbon moving between
the air and the living things in
the tank? What is happening to the amount
of carbon in living things?
Just tell me those two questions plz help me I will give you my points I swear plz help me I beg you
The amount of carbon is captured by plants to perform photosynthesis as a light for the tank has been on all day and prepare their own food. The product of photosynthesis is consumed by other organisms to perform cellular respiration.
What are the components of photosynthesis?The components of photosynthesis may include carbon dioxide, water, and sunlight as raw materials to convert into glucose (a food molecule).
The amount of carbon will not remain the same for the entire time in the living organism. The cycling of carbon is processed synergistically during photosynthesis and cellular respiration.
Living things in the tank respire out carbon, which is taken up by plants for photosynthesis, a product of photosynthesis are the reactants for cellular respiration. In this way, carbon delocalized among the living entities.
Therefore, it is well described above.

Explanation:whater
Research showed differences in living environments is the best reason for scientists to separate the prokaryotes. Therefore, option (D) is correct.
What are prokaryotes?The organisms known as prokaryotes lack a nucleus and other organelles in their cells. There are two distinct groups of prokaryotes: the archaea and bacteria, both of which are thought to have evolved along distinct evolutionary lines.
Prokaryotic organisms or prokaryotes are organisms that lack a true nucleus and membrane-bound cell organelles. Mycoplasma, cyanobacteria, and bacteria are all examples of prokaryotes.

This molecule provides stability to the phospholipid bilayer and without it the membrane would easily fall apart.
Answer:
The correct answer is - cholesterol molecules.
Explanation:
Cholesterol molecules are the molecules that acts as a bidirectional regulator for the lipid bilayer as it provides fluidity by raising the melting point of the membrane at high temperature and stabilize the membrane.
On the other hand, it also prevents the membrane from clustering or being tough or stiff by intercalates between the phospholipids at low temperatures. Therefore it is the molecule that provides stability to the membrane.
