Based on the information given, state ONE way the bag or its contents will have changed by the next day. Support your answer with an explanation. *

Answers

Answer:

The size of the bag will shrink due to movement of water molecules out of the bag into the beakerdue to osmosis.

Explanation:

The difference in concentration between two regions results in a phenomenon known as diffusion.

Diffusionnis the process by which molecules of a substance move from regions of higher concentration to regions of lower concentration until equilibrium concentration is reached by the two regions. Water molecules moves across regions of different concentration through a semipermeable membrane in a special form of diffusion known as osmosis.

Osmosis refers to the movement of water molecules from regions of high concentration (dilute solutions ) to regions of low concentration (concentrated solutions ) through a semipermeable membrane until equilibrium is attained.

The solution in the bag is less concentrated than the solution innthe beaker. The bag serves as a semipermeable membrane allowing water molecules to move out of it into the beaker due to the difference in concentration of the two solutions. As a result, the size of the bag shrinks while the level of the solution in the beaker rises as it becomes less concentrated.

Q. How is the sex of the child determined in human beings ?
Please answer dis also..thanks!​

Answers

➜ In human beings, sex of the child depends upon which kind of male gamete fertilise the female gamete. If sperm carrying X chromosome fertilises the ovum carrying X chromosome, then the child born will be a girl. If a sperm carrying Y chromosome fertilises the ovum which carries X chromosome, then the child born will be a boy.

What might happen to the cell if it were suddenly unable to use lipids?

(A) It would not be able to make proteins or transfer substances to other cells

(B) Would not be able to transfer genetic information to other cells

(C) It would not be able to store energy or communicate with other cells

(D) It would not be able to store water or protect itself from viruses

Explanation:

Water moves in and out of a cell in conformity with the concentration gradient formed between the membrane of the cell and the extracellular solution. The process whereby the water moves from a region of low solute concentration to a high solute concentration via a semi-permeable membrane is called OSMOSIS.

In this case, the solute concentration of the blood cannot be regulated, hence, it rises. This causes the solute concentration of the blood to be high or is said to be hypertonic than the cell's. This creates an osmotic gradient causing water to flow out of the hypotonic (low solute concentration) cell into the hypertonic extracellular environment (blood). Once water flows out of the cell as a result of osmosis, the cell shrinks or shrivels i.e. reduce in size.

how do Solids, liquids and gasses change states?

Answers

you melt a solid to turn into a liquid, then you boil the liquid to turn it into gas

Someone already answered but i’m going to provide more detail.
If you have an ice cube which is a solid and it melts, it turns into liquid water instead of frozen. Now, if you put that same water in a pot on top of a stovetop, once it reaches boiling point (212°F) then it will turn into a gas and start to bubble. I hope this helps! :]

One of the major concerns about seawater desalination is its high expense. Another concern is the disposal of leftover brine from the desalination process back into the ocean, which harms marine life. Discuss whether these two concerns are enough to prohibit the widespread use of desalination as a source of drinking water.

Answers

Answer:

Yes.

Explanation:

Yes, these two concerns are enough to prohibit the use of desalination as a source of drinking water because this method is too expensive as well as bad for the marine environment. First, this desalination process is too expensive which is non-economical for the country while on the other hand, it greatly damaged the aquatic animals so this method must be stopped due to its adverse effect on both economics as well as environment.

The ratio of offspring with the described traits to the total number of offspring would be 9/16, 3/16, 3/16, and 1/16 respectively.

What are dihybrid crosses?

They are crosses involving two traits. when the traits are independent, the phenotypic ratio of the resulting offspring follows the ratio established by Mendel.

In this case, the two traits follow the Mendelian pattern and thus, assort independently.

Hence, the traits and their respective ratios would be:

Brown body, Red eyes - 9/16

Brown body, brown eyes - 3/16

Black body, red eyes - 3/16

Brown body, brown eyes - 1/16
