HELPPP!!! What would the mass of an artificial cell containing 20mL of a 25% sugar solution be after it was placed in a beaker containing a 30% sugar solution for 30 minutes? Remember to include units in your answer.
Answers
Answer: The sugar will move from the 50 % concentration to the 0 % concentration.
Explanation:
Dialysis is an analytical technique which uses a semipermeable membrane in order to remove the impurities from the body.
This technique is used when the kidney failure inside the body takes place. The kidney inside the body perform function of filtration, when kidney failure takes place then the dialysis is used.
In this case the tubing bag containing 0% sugar is put into a sugar solution having 50% solution.
After sometime the sugar will move from 50 % to 0% bag because of the phenomenon known as osmosis.

Answer:
He defined natural selection as the "principle by which each slight variation, if useful, is preserved".

Darwin's Theory of Evolution by Natural Selection
More individuals are produced each generation that can survive. Phenotypic variation exists among individuals and the variation is heritable. Those individuals with heritable traits better suited to the environment will survive.

How does the body protect itself from the majority of pathogens it encounters?
Answers
Answer:
In general, your body fights disease by keeping things out of your body that are foreign. Your primary defense against pathogenic germs are physical barriers like your skin. You also produce pathogen-destroying chemicals, like lysozyme, found on parts of your body without skin, including your tears and mucus membranes. In response to infection, your immune system springs into action. White blood cells, antibodies, and other mechanisms go to work to rid your body of the foreign invader. The immune system has a vital role: It protects your body from harmful substances, germs and cell changes that could make you ill. It is made up of various organs, cells and proteins.
Once infected cells have sensed an invading pathogen, they secrete molecules called cytokines and chemokines. These cells are then primed to resist an infection with the invading virus. Cytokines such as interferons activate anti-viral genes in the infected and neighbouring cells.
Microorganisms capable of causing disease—or pathogens—usually enter our bodies through the eyes, mouth, nose, or urogenital openings, or through wounds or bites that breach the skin barrier. Organisms can spread, or be transmitted, by several routes.
The second line of defense is nonspecific resistance that destroys invaders in a generalized way without targeting specific individuals: Phagocytic cells ingest and destroy all microbes that pass into body tissues. For example macrophages are cells derived from monocytes (a type of white blood cell).
If pathogens do manage to enter the body, the body's second line of defense attacks them. The second line of defense includes inflammation, phagocytosis, and fever.

C. Commuters who live in suburbs are dependent on mass transit systems that

D. Commuters who live in suburbs are dependent on mass transit systems that
add to water pollution.
Answers
Commuters drive personal vehicles to their places of work: offices, manufacturing plants etc.
Some may use car pooling or mass transit like buses. But too many want the luxury and convenience of coming and going on their own terms.
IMHO car pooling and mass transit needs to be used more to reduce environmental harm.

AND PLEASE MARK ME AS "BRAINLIEST" ANSWER
HOPE IT HELPS YOU
The examples of geological processes that occur slowly is soil erosion and weathering.
What do you mean by soil erosion?Soil erosion is the denudation or wearing away of the upper layer of soil. It is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice, snow, air, plants, and animals.
Soil erosion occurs primarily when dirt is left exposed to strong winds, hard rains, and flowing water. In some cases, human activities, especially farming and land clearing, leave soil vulnerable to erosion.
Removing trees and plants, plowing fields, and overgrazing by livestock disrupts roots that stabilize sediment and soil. These human activities can increase erosion rates 10 to 100 times that of non-human geologic processes.

In fission, how does the DNA of the daughter cells compare to the DNA of the parent cells?
It is exactly the same
It is different due to meiosis
It it mostly the same with slight changes
It is better than the parent DNA
Answers
Answer: It is exactly the same!
In fission, the DNA of the daughter cells compared to the DNA of the parent cells will be exactly the same. The correct option is A.
What do you mean by a parent cell and a daughter cell?The cell that divides to produce two daughter cells is known as the mother or parent cell in the process of cell division. Mitosis produces two offspring cells that are genetically identical to the mother cell. We are all alive now due to a process known as mitosis.
Mitosis is the process through which a single cell divides into two new, identical cells. The initial cell is known as the parent cell, while the newly created cells are known as the daughter cells.
The daughter cell is exactly identical to the mother cell, that's why the DNA will also be the same in both cells.
Therefore, the correct option is A. It is exactly the same.
