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.

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.

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.

A prokaryotic cell carries out every one of the fundamental roles that an ordinary cell performs. Reproduction, respiration, digestion, and other biological processes are among their capabilities.

The figure C represents Five kingdom classification.

The system of biological kingdoms is the way in which science classifies living things according to their ancestry over the course of evolution.

This means that all the species that make up these five large groups - some recent theories split them further into six or even seven - have common ancestors and therefore share some of their genes and belong to the same family tree.

As well as the kingdoms of living things there are other taxonomic categories within the same classification system such as, for instance, domain, phylum, class, order, family, genus and species.

Answer:

Internal and external regulators are two types of proteins that regulate the cell cycle. Internal regulators allow the cell cycle to proceed only after certain events occur. External regulators speed up or slow down the cell cycle.

Explanation:

I hope this helps :)

The two types of proteins that regulate the cell cycle are Cyclins and Cyclin-dependent Kinases (CDKs). These two groups of proteins are responsible for the progress of the cell through various checkpoints.

What are Proteins?

Proteins are made up of hundreds or thousands of smaller units called Amino acids. They are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body’s tissues and organs.

Cyclins regulate the cell cycle only when they are bound to Cdks and become fully active. The Cdk/cyclin complex must be phosphorylated, which further initiates other proteins to be phosphorylated that advances the cell cycle.

Retinoblastoma (Rb), is another group of tumor-suppressor proteins that regulates the cell cycle by monitoring the cell size.

Therefore, there are two types of proteins that regulate the process of the cell cycle are Cyclins and Cyclin-dependent Kinases (CDKs).

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%

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

Both sides of the equation must equal each other by .50, so .50 - .22 = .28

.28 x 100 = 28%

Answer:

Alfred Hershey and Martha Chase

Explanation:

In 1952 Alfred Hershey and Martha Chase were working with bacteriophages or phages, which are viruses that infect bacteria. They knew that a phage had an outer shell of protein and an inner core of DNA. In addition, from the electron microscope observations, they also knew that during infection the virus attacks the bacterium by its tails and introduces its genetic material into the bacterium to multiply using its metabolic machinery. They radioactively labeled two sets of phages: one with 32P (which marks only DNA) and another with 35S (which marks only proteins). In two parallel experiments, they infected bacteria with viruses marked on their DNA and with viruses marked on their proteins. The cultures were shaken with a mixer to separate the virus particles from the bacterial coatings. They then performed a centrifugation to separate the phages from the bacteria, so that the larger and heavier bacteria remain in the pellet, while the phages remain in the supernatant. They found that the radioactivity of 35S appeared in the supernatant while that of 32P appeared in the sediment, from which new radioactively labeled virus particles appeared, demonstrating that DNA was the genetic material.

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.

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.

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.

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.

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,

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,

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
