100%

Explanation:

because that quistions are finish answing with me

The checkpoint should the drug interrupt the cell cycle to keep DNA from replicating is G2 Checkpoint. Thus, option B is correct.

Cell cycle has been defined as the cycle in which cell produces, grows and divides. The cell cycle has mainly three steps the first one has been known as G1 phase in which the size of cell increases, S phase synthesis of DNA takes place and the third step has been G2 phase in which cell ready to divide.

Cell has been defined as the base of life as it has the structural as well as functional unit of life. Cell has been made up of pre existing cells and the cell contain various cell organelles such as mitochondria, endoplasmic reticulum, ribosomes, golgi appratus, nucleus, and cytoplasm.

Basically, cell has been of two type one in prokaryotic and another one is eukaryotic. The prokaryotic cell has been known as pre mature cells as they do not contain cell organelles and eukaryotic cell are known as advanced and developed cells as they contain several cell organelles.

Therefore, The checkpoint should the drug interrupt the cell cycle to keep DNA from replicating is G2 Checkpoint. Thus, option B is correct.

an animal can be both a prey and a predator because the animal may eat meats but can be eaten by animals that are larger than him that also eat meat like a snake will eat field mice but a hawk will swoop down and eat him.

Explanation:

An animal can be both a prey and a predator because the animal may eat meats but can be eaten by animals that are larger than him that also eat meat like a snake.

Organisms that hunt and kill other organisms for food are known as predators. The term "prey" refers to the organisms that the predators consume. Omnivores and carnivores are two types of predators. Predators include sharks, snakes, tigers, and lions.

Wild animals that hunt or prey on other animals are called predators. To survive, all animals require food. To survive, predator animals consume the flesh of their prey. Weasels, birds of prey, wolves, mountain lions, and wild bears are hunters.

It's possible that there will always be someone who wants to take advantage of you. A human predator is someone who tries to take advantage of someone who is weak or in a vulnerable moment, according to my definition.

a compound light microscope

Answer:

Oxygen

Explanation:

  Both consumers and producers perform cellular respiration to produce the oxygen necessary to sustain life.

Cellular respiration gives energy to the consumer by using oxygen.

The process through which food, in the form of sugar (glucose), is converted into energy within cells is known as cellular respiration. It gives cells the energy they require to work. Food would be completely useless if living beings couldn't obtain the energy they required from it. No matter the type or quantity of nourishment, all living beings will eventually perish.

There are two types of cellular respiration and that is aerobic respiration and anaerobic respiration.

Both the cytosol and mitochondria of cells participate in cellular respiration. While pyruvate oxidation, the Krebs cycle, and oxidative phosphorylation take place in the mitochondrion, glycolysis happens in the cytosol.

The concentration of the solute that is needed is calculated by molarity which is by the formula that is number of moles of  solute molecules divided by the volume in ml.

Moles of solute are calculated by the given mass divided by molar mass.

The given mass is 2.5 mg/mL  that is 2.5 multiplied by 10 raise to the power 3 that is 1000. The answer to it is 2500.0g/ml  divided by 125 that is the values put in the formula that is moles of solute which are molar mass of gelatin that is 10000, given mass = 2500 / 10000 which is 0.25 now it is divided by the volume.

The volume is 125 ml that is put in the denominator in which it is like 0.25/125 that is 25 X 10 raise to the power -2 by 125 that is multiplied with 1000 such that the answer is 312.5 g which is the answer.

Answer: 5800 K

Explanation:

The Sun is a star found in the center of the solar system amd almost a perfect sphere of plasma. It constitutes the largest source of electromagnetic radiation in this planetary system and it also generates a magnetic field through a dynamo process. About three-quarters of the Sun's mass consists of hydrogen while the rest is mainly helium, with much smaller amounts of other elements such as oxygen, carbon, neon and iron.

Such as any other star, the Sun has a spherical shape, and because of its slow rotation movement, it also has a slight polar flattening. All the matter that constitutes it is attracted towards the center by its own gravitational force. However, the plasma that forms the Sun is in balance, since the increasing pressure in the solar interior compensates the gravitational attraction, which generates a hydrostatic balance. These enormous pressures are produced due to the density of the material in its nucleus and to the enormous temperatures that occur in it thanks to the thermonuclear reactions that take place there. There is, besides this thermal contribution, one of photonic origin which is the radiation pressure caused by the enormous flow of photons emitted in the center of the Sun.

The quantum mechanics allows to calculate the spectral lines of the atoms and molecules that compose the solar atmosphere at any temperature, however the calculation is not easy. For this reason there are several heavy atomic elements with spectral lines that have transition probabilities that are still uncertain.

However, despite being complicated, scientists have determined that the surface temperature of the Sun is around 5800 K.

Answer: C

Explanation: it produces nitrogen compounds that humans can breath . It is the only logical choice.

It converts nítrogen into a form that humans can obtain by eating other organisms.

The conversion of nitrogen between its different life-supporting forms, including nitrates and ammonia, occurs naturally as part of the nitrogen cycle. The nitrogen cycle creates free nitrogen that people can breathe, which is one of the most significant ways it is vital to people.

Humans cannot survive without nitrogen, which is necessary for all life. Additionally, the nitrogen cycle changes nitrogen into a form that people can consume by eating other living things like plants and animals. This is significant because it enables people to obtain the essential nutrients from their diet.

The nitrogen cycle also creates nitrogen molecules for human inhalation. These substances are crucial for preserving a healthy environment and can lessen the impacts of air pollution.

Last but not least, the nitrogen cycle also changes nitrogen into a form that people can absorb via their skin. This can lower the chance of developing specific medical disorders by preserving a healthy balance of nitrogen in the body.

Answer:

B

Explanation:

Hes the inventor of the punnet square. Sorry not enough info but that is your answer.

interphase occurs only once in both meiosis and mitosis

The stage in the cell cycle that occurs only once, in both mitosis and meiosis, is interphase. The correct option is B.

The cell cycle is a process of the growth and division of cells. The normal cell performs these cell cycles for division and growth. The sex cells perform the cell cycle and meiosis when reproduction occurs.

The cell cycle completes in a four-stages:

1. gap 1, or G1, stage- cell increase in size.

2. synthesis, or S, stage- DNA copy.

3. gap 2, or G2, stage- prepare to divide.

4. mitosis, or M, stage- division occurs.

In mitosis, the process of interphase occurs. In interphase, the cell divides and the chromosomes are copied, and it prepares for division.

Thus, the correct option is B, interphase.
