Answer:

The cell cycle

Explanation:

Answer:

The polarity of water molecules and the hydrogen bonds between water molecules explain most of water's life-supporting properties.

The cohesion of water molecules to each other helps transport water from the roots to the leaves on plants.

When water warms or cools, hydrogen bonds either break or form.

Thus, water absorbs or releases a great deal of heat, helping to moderate temperatures.

Water is a versatile solvent.

Blood and other biological fluids are aqueous solutions with a diversity of dissolved solutes.

Explanation:

The sentences presented in the question above had their various spaces complemented by the words that best fit the sentence and that were capable of forming true invormations on water.

Water is a very versatile solvent as it is capable of dissolving and mixing with various substances both liquid and solid. Furthermore, water has a great capacity to absorb or release heat, which is very useful for the entire planet, as this allows water to be very efficient in regulating temperature.

Water is formed by H2O molecules, which hold these molecules together are the hydrogen bridges formed between them. Hydrogen bridges are broken through heat, which allows the water to evaporate, but at low temperatures these bridges are strengthened and new bridges can be created, which allows the water to become solid.

The properties of water are extremely important for life on the planet and for most biological processes we know about. Among these properties we can mention polarity and cohesion as one of the most important. Polarity allows water to be a polar substance, while cohesion allows water to create an attractive relationship between molecules.

The process that must happen before meiosis can begin is that DNA doubles and produces sister chromatids (Option C).

Meiosis is a cell division process that generates four daughter cells having half of the DNA when compared to the parental cell.

Meiosis needs first the duplication of the genetic material by means of a synthesis stage (S phase).

In conclusion, the process that must happen before meiosis can begin is that DNA doubles and produces sister chromatids (Option C).

Explanation:

Answer:

One key way by which species evolve over time in response to changes in environmental conditions is adaptation by natural selection acting over generations. Characteristics that aid in effective survival and reproduction in the new environment grow more prevalent, while those that do not become less prevalent.

Explanation:

is type of carbohydrates

False. Starch is a polysaccharide used as an energy storage molecule in plants, but it is not a component of cell walls.

Cell walls are structural components found in the outermost layers of cells in plants, fungi, and some bacteria. They provide support and protection for the cell, and are composed of a variety of different biomolecules, including cellulose, pectin, and lignin.

Starch, on the other hand, is a complex carbohydrate that is synthesized and stored in the cells of plants, particularly in the seeds, roots, and tubers. It is made up of long chains of glucose molecules and is used by plants as an energy source, particularly during times when the plant does not have access to light for photosynthesis. Starch is not a component of cell walls.

Answer:

The cell is flexible and assumes a bell shape as it passes through extremely small blood vessels. It is covered with a membrane composed of lipids and proteins, lacks a nucleus, and contains hemoglobin—a red iron-rich protein that binds oxygen.

Answer:

The cell is flexible and takes the form of a bell through extremely small blood vessels. It is clothed in a fluid and protein-membrane, lacks a nucleus, and has hemoglobin—a rich red iron protein that binds oxygen.

Explanation:

The hemoglobin in red blood cells contains four iron-binding heme groups.

Heme groups of hemoglobin are binding on oxygen. Each molecule of hemoglobin can bind up to four molecules of oxygen.

Hemoglobin has a cooperative binding affinity to oxygen. The saturation of the molecule increases by oxygen. The connection of the initial molecule of oxygen affects the form of the other binding sites. For additional oxygen molecules, the binding becomes more favorable.

The four iron-binding hemo-groups are located in each hemoglobin molecule. Hemoglobin is known as oxygen-bound hemoglobin.

The reversible carbon dioxide is transformed into the carbonic acid reaction by the enzyme carbenoid anhydrase by the Red blood cells altering the blood PH.

Instead of being converted to carbonic acid, pH is controlled by carbon dioxide bindings to hemoglobin.

CO2: The enzyme found in RBCs catalyzing the reaction between carbonic anhydrase and carbonate dioxide and water.

Co-operative binding: When a first molecule is binding to a binding location, the same molecule is favored for the remainder of the binding locations by means of increased binding affinity.

Explanation:

This situation is called an incomplete dominance. A great example of this is when a plant with red flowers is paired with a plant with white flowers and the seeds give plants with pink flowers

Answer:

The correct answer is - Disruptive selection.

Explanation:

Disruptive selection is a mode of natural selection that exhibits that two extreme values of phenotypic traits of the population are favored by this population than the population with their intermediate values. Disruptive selection occurs when there is a fitness advantage of extreme values of phenotypic traits over more intermediate phenotypes.

In this case, the largest males mates more, due to fact that they can guard the females, than smaller males. The smallest fishes also get a high number of mates as are able to mate with the females quickly without coming to the notice of larger males.

Explanation:

the reason this mouse shows natural selection is that the black mouses are more adapted to their environment compared to the tan mouses as the tan mouses are more easily spotted and eaten by the bird. since the black mouse is more adapted to it's environment it is more likely to live on and pass it's trait of the black fur color to it's offspring while the tan mouses are not.

Answer:

Ingestion: Consuming something orally, whether it be food, drink, medicine, or other substance; the first step of digestion. bolus: a round mass of something, especially of chewed food in the mouth or alimentary canal.

Propulsion: Propulsion means to push forward or drive an object forward. A propulsion system is a machine that produces thrust to push an object forward. On airplanes, thrust is usually generated through some application of Newton's third law of action and reaction.

Mechanical Digestion: Mechanical digestion is a purely physical process that does not change the chemical nature of the food. Instead, it makes the food smaller to increase both surface area and mobility. It includes mastication, or chewing, as well as tongue movements that help break food into smaller bits and mix food with saliva.

Chemical Digestion: Chemical digestion involves the secretions of enzymes throughout your digestive tract. These enzymes break the chemical bonds that hold food particles together. This allows food to be broken down into small, digestible parts.

Absorption: Absorption is a condition in which something takes in another substance. The process of absorption means that a substance captures and transforms energy. The absorbent distributes the material it captures throughout whole and adsorbent only distributes it through the surface.

Defecation: Defecation is the term given for the act of expelling feces from the digestive tract via the anus.
