When we see chiasmata under a microscope, that lets us know which of the following has occurred? A) asexual reproduction
B) meiosis II
C) anaphase II
D) prophase I
E) separation of homologs

Answers

Answer 1

Answer: When we see chiasmata under a microscope, that lets us know that prophase I has occurred. During this phase of meiosis, the nuclear envelope breaks up and disappears, and so does nucleolus. The chromosomes become visible at this point.

During the cell cycle, specifically G1 interphase, a cell must reach a sufficient size and produce enough ATP in order to A) undergo mitosis. B) undergo cytokinesis. C) produce 2 daughter cells. D) replicate its chromosomes.

Answers

Answer:

The correct answer will be option-D

Explanation:

The cell cycle is the cyclically ordered sequence of events taking place in the cells associated with the division of the cell.

The cell cycle takes place in two phases: the interphase proceeded by M-Phase. The interphase of the cell cycle proceeds in G₁, S and G₂ phase. During the G₁ phase, the cell prepares itself to prepare for the next important phase marked by the synthesis or replication of the genetic component of the cell.

The changes that take place during the G₁ phase thus includes the increase in size and the production of ATP as DNA replication is an energy-dependent process.

Thus, Option-D is the correct answer.

Answer:

During the cell cycle, specifically interphase, a cell must reach a sufficient size and produce enough ATP in order toreplicate its chromosomes.. Most of interphase is spent in G1. It is followed by S or the synthesis of chromosomes and then a second growth phase. This phase produces more ATP so the cell can divide.

A complication risk of gastric bypass surgery that bypasses most of the small intestine is ____.

Answers

The answer would be vitamin and mineral deficiencies.

The small intestine has a role in food digestion and absorption. Bypassing most of the small intestine will reduce the food transit time there, thus reducing the amount of substance that can be absorbed.
These surgery supposed to help diabetes type 2 patient, not making it worse. It should be not related to kidney or muscle.

Answer: Malnutrition

Explanation: When a surgeon cuts an area of small intestine then the main problem that can be faced is malnutrition.

This is because small intestine is the main organ for the absorption of nutrients in the body.

If it is cut down then the absorption of many nutrients, vitamins an minerals will be affected.

The correct answer is malnutrition.

The picture shows a contractile vacuole of unicellular freshwater

Answers

Answer:

organism, called Paramecium. The contractile vacuole is a specialized organelle responsible for maintaining osmotic balance and regulating the water content within the cell. Paramecium lives in freshwater environments, where water continuously enters the cell through osmosis. The contractile vacuole collects excess water from the cytoplasm and pumps it out of the cell through a series of canals. This process helps Paramecium prevent the cell from bursting due to excessive water intake. The contractile vacuole also helps in removing waste materials from the cell. The picture shows a spherical contractile vacuole with multiple canals leading to the cell's surface, through which water is expelled. Overall, the contractile vacuole is a vital organelle for maintaining the internal balance and survival of unicellular freshwater organisms like Paramecium.

True or false Children and adults can both benefit from having a dietician.

Answers

True. Children and adults can both benefit from having a dietician.

A dietitian (dietician) is an expert in dietetics; human nutrition and the regulation of diet. He or she advises people on what to eat in order to lead a healthy lifestyle or to achieve a specific health-related goal.

Children usually do not think of their overall well being when eating. All they are concerned about is being fed food that tastes good preferably sweet. They do not think about the required nutrients they find in their food nor do they think about the future health consequences of their food choices. Thus, a dietician is needed.

Adults need dieticians too. Mostly because they already are experiencing negative consequences from unhealthy eating practices since childhood. They need dieticians to lower the negative effect and bring their health back to normal.
