Stellar evolution is the process by which a star undergoes a sequence of radical changes during its lifetime. Depending on the mass of the star, this lifetime ranges from only a few million years (for the most massive) to trillions of years (for the less massive), considerably more than the age of the universe. ^
Small, relatively cold, low mass red dwarfs burn hydrogen slowly and will burn for hundreds of billions of years
Massive hot supergiants will live for just a few million years.
A mid-sized star like the Sun will remain on the main sequence for about 10 billion years. Hope tis helps!!
Answer:
Explanation:
Active transport is the movement of molecules or substance from a region of lower concentration to a region of higher concentration across a cell membrane against the concentration gradient.
Active transport requires cellular energy and are of two types:
primary active transport that uses adenosine triphosphate (ATP), and secondary active transport that uses an electrochemical gradient.
Active transport helps in the uptake of glucose in the intestines.
Cotransport or secondary active transport is the movement of molecules across a membrane it uses electrochemical potential difference that is created by pumping ions in or out of the cell.
Cotransport helps in the transport of glucose across the cell membrane.
Hey there!
Here is your answer:
Since there are not options im going to go with what i know:
<u>(Alleles)</u>
<span><u>heterozygous: A,a</u>
</span><u>homozygous: a,a</u>
<u>Therefore the Punnett square should look like this:</u>
<u>A, a</u>
<u>a IA,a I a,a</u>
<u>a IA, a I a, a</u>
Therefore the answer is 50% A,a , and 50% a, a!
If you need anymore help feel free to ask me!
Hope this helps!

Answer:
The correct answer will be option- adhere to cell surfaces.
Explanation:
The bacterial fimbriae are the cellular appendages which help the bacteria to attach to a substratum. This attachment property of the fimbriae is due to the presence of a protein called adhesins.
The fimbriae are also known as the attachment pilus of the bacteria which are thinner than a flagellum. The bacteria posses many fimbriae to adhere to the surface like to receptors, another bacteria or any other substratum.
Thus, option- adhere to cell surfaces is the correct answer.
