Answer: Osmosis
Explanation:
Osmosis is a type of simple diffusion in which water molecules diffuse through a selectively permeable membrane from areas of high water concentration to areas of lower water concentration.
For a person with blood type A- (A negative), they can be transfused with either blood type A negative , or blood type O negative.
This is because any other blood type will immediately be rejected by their body.
A person with blood type A negative has got antibodies against any other blood type which has a rhesus positive factor as well as antibodies against any other blood type of a different group such as B and AB, even if they are rhesus negative.
Therefore because of the rhesus negative factor, a person with blood type A negative can only be transfused with rhesus negative .
Answer:
Option D: O-
Explanation:
They can also receive blood type A-, but that's not one of the options on the test.
Answer:
C
Explanation:
Got it right
B.) A gene is inserted to make a mutation inactive.
C.) A gene is inserted in a plant to make it pest resistant.
D.) GMO plants are created to withstand droughts.
DNA used to determine paternity is not an example of genetic engineering. Therefore, option A is correct.
Genetic engineering is also known as genetic modification or gene editing. It is the process of manipulating the genetic material of an organism to alter its characteristics or traits. This is typically done by introducing specific genes or modifying existing genes within an organism's DNA.
Genetic engineering involves the use of various techniques, such as gene splicing, gene editing, and gene transfer, to introduce or modify genes in an organism's DNA. This can be done in a variety of organisms, including plants, animals, and microorganisms. '
DNA used to determine paternity is not an example of genetic engineering. Therefore, option A is correct.

Answer:
The answer is A.) DNA is used to determine paternity.
Explanation:
I just took the test and if your like me and watch things like judge Judy and things of that sort she usually says that they take DNA tests to figure out if someone is or isn't THE FATHER. Judge Judy's court is a paternity court.
Answer:
Sharks have some fascinating features which make these animals to be best adaptable to live in an aquatic environment and also for hunting.
Some of the physiological features include:
1) The skeletons of sharks is not made up of bones, rather it is made up of cartilages. This makes the skeletons of sharks lighter and more flexible.
2) The esophagus of sharks is short but wide which makes it adaptable for swallowing smaller preys. It also allows the larger preys to be gulped down.
3) A shark eats only about 5% of its body weight per week. It can survive without food for many days due to its slow metabolism.
A. A yeast cell reproduces itself.
B. Oxygen and CO2 are exchanged in lungs.
C. The eye interprets an image.
D. Chloroplasts turn light energy into chemical energy.
Answer:
A. A yeast cell reproduces itself
Explanation:
Yeast cell can reproduce asexually either by budding or fission. No matter which process, the ultimate result is cell division.
In fission, first the nucleus divides into two nuclei so that the cell contains two nuclei. Then, a constriction is laid down between the cell which eventually divides the cell into two daughter cells, each with its own nuclei.
In budding, the cell wall at one corner of the yeast softens. This portion starts to grow as a bud while still attached to the mother cell. Eventually the nucleus also divides with one daughter nuclei migrating to the bud. Finally when the bud attains the size of parent cell, cell division occurs.
Answer:
A. A yeast cell reproduces itself.
Explanation:
Should be the right answer because cell division is necessary during reproduction. Like a sponge, it separates itself (essentially the cells) and regrows the parts needed.
