Answer:
The process in which one bacteria transfers DNA to another is called conjugation.
Explanation:
Conjugation is the process of transferring genetic material from one bacteria to another through direct cell contact. In the process of conjugation one bacteria acts as donor and transfer the DNA to a recipient. There is a specific DNA sequence present in Donor's DNA called fertility factor (F factor). F factor helps in the formation of pillus which is the site of genetic material transfer.
B a star
C a nebula
D the sun
E the force of gravity
Answer: Option 'B' is correct.
Explanation:
All the iron molecules that are in your body were originally created by a star.
During a star supernova, a very large amount of energy and neutrons are released by stars which allows heavier elements to be produced.
And when there is explosion of star occurs, those elements are found which is used to make DNA and DNA contains large amount of iron molecules.
Hence, Option 'B' is correct.
I think the answer is B - a star! Hope this helps!
a substance that moves across a cell membrane without using the cells energy tends to move? a.) away from the area of equilibrium b.) away from the area where it is less concentrated. c.) away from the area where it is more concentrated d.) toward the area where it is more concentrated
Answer: The correct option is C.) away from the area where it is more concentrated.
A substance that moves across a cell membrane without using the cells energy tends to move from an area of high concentration to an area of low concentration.
This is known as Passive transport. In this transport, substances move down the concentration gradient i.e from an area of high concentration to an area of low concentration. It is also called simple diffusion as no energy is required in this process.
