Answer:

m

Explanation:

Mitosis is divided into four phases: prophase, metaphase, anaphase, and telophase. The shortest stage of the cell cycle is called cytokinesis (division of the cytoplasm). In cytokinesis, the cytoplasm and its organelles divide into two daughter cells. contains a nucleus with an identical set of chromosomes.

Answer:

transcription

Explanation:

The correct answer is true.

It is true that natural selection is defined as individuals that have certain inherited traits tend to survive and reproduce at higher rates because of these traits.

Based on the concepts developed by scientists Charles Darwin, natural selection is the way species and all living organisms on planet earth transform and adapt to the environmental conditions where they live.

Charles Darwin did deep research in South America and some islands in the region and researched fossils, animals, and vegetation.

In 1869, he published his interesting results in a book called "On the Origin of Species."

Answer:

3

Explanation:

Answer:

If internal barriers to gene flow do not evolve, individuals from the two parts of the population will freely interbreed if they ... They result from natural selection, sexual selection, or even genetic drift: ... Genetically-based changes to these aspects of mating could complete the process of reproductive isolation and speciation.

Answer: When oxygen is present, aerobic respiration occurs, which releases carbon dioxide into the surrounding air or water. Otherwise, anaerobic respiration occurs and releases methane into the surrounding environment, which eventually makes its way into the atmosphere or hydrosphere.

Answer:

DNA is unzipped

Explanation:

Learned it in Biology

Answer: A

Explanation:These organisms are made of prokaryotic cells — the smallest, simplest and most ancient cells. Organisms in the Eukarya domain are made of the more complex eukaryotic cells. These organisms, called eukaryotes, can be unicellular or multicellular and include animals, plants, fungi and protists

Answer:ahh yes the ball torture method good one indeed umm the answer will be the 28th option aka letter R

Explanation:

Answer:

1) B) insulin  

2) A) glucagon  

3) C) epinephrine  

4) B) insulin  

5) A) glucagon  

6) A) glucagon  

Explanation:

High levels of glucose in the blood promote the release of insulin hormone which functions to stimulate uptake and utilization of glucose by cells. Insulin may also act to inhibit lipolysis in adipocytes and stimulates triglyceride storage. Glucagon hormone controls blood sugar (glucose) by stimulating glycogenolysis (conversion of glycogen to glucose), promoting gluconeogenesis (glucose synthesis), and inhibiting glycolysis (glucose breakdown). Moreover, glucagon also can increase ketogenesis (i.e., the production of ketone bodies by breakdown of fatty acids and ketogenic amino acids) when insulin is inhibited. Finally, epinephrine hormone binds to receptors localized on the surface of muscle cells, which stimulate the production of cyclic-AMP (cAMP), a second messenger (i.e., a signaling molecule).

Answer:

18

Explanation:

all the law is saying is that matter cant be created nor destroyed, so if 18 oxygen atoms are used, there will be 18 oxygen atoms in the end, no matter what, doesn't matter what they use it for or what

Answer:

A

Explanation:

Pairs of homologous chromosomes exchange segments is the phrase that best describes the process of crossing over.

The process of crossing over is the exchange of genetic material specifically of a DNA segment that happens between two pairing chromosomes, that is, they exchange sections of their DNA.

Therefore, we can conclude that pairs of homologous chromosomes exchange segments of their DNA is the phrase that best describes the process of crossing over.

Answer:

See below

Explanation:

Active transport is the movement of materials across a membrane that requires an input of energy from a cell. This is because ions move into and out of cells and because cells contain proteins that do not move across the membrane and are mostly negatively charged, there is also an electrical gradient, a difference of charge, across the plasma membrane. the interior of living cells is electrically negative with respect to the extracellular fluid in which they are bathed.

At the same time, cells have higher concentrations of potassium (K+) and lower concentrations of sodium (Na+) than does the extracellular fluid. In a living cell, the concentration gradient of Na+ tends to drive it into the cell, and the electrical gradient of Na+ (a positive ion) also tends to drive it inward to the negatively-charged interior. The situation is more complex, however, for other elements such as potassium.

To move substances against a concentration or electrochemical gradient, the cell must use energy. This energy is harvested from adenosine triphosphate (ATP) generated through the cell’s metabolism. Active transport mechanisms, collectively called pumps, work against electrochemical gradients. Small substances constantly pass through plasma membranes. Active transport maintains concentrations of ions and other substances needed by living cells in the face of these passive movements.
