Answer:
D
Explanation:
you can't take one type of cell and create a brand new one. This gets rid of C
the only cell that increases in size is fat cells, this gets rid of A
Mitosis is for all cells, except sex cells. Daughter cells relate more to sex cells than other cells. Sex cells go through meiosis to create daughter cells. This also gets copies DNA. This gets rid of B
Basically: Mitosis is how we make new cells from the original cell (Think Zygote cell)
Answer: The correct option is (the region of an enzyme that attaches to a substrate).
Explanation:
The anabolic and catabolic processes in a cell are directed and regulated by enzymes. An enzyme has the ability to speed up a metabolic reaction by lowering the amount of energy needed to start the reaction. Without enzymes, these processes would be extremely slow. They also arrange the reacting molecules in a manner that will cause the chemical change to take place rapidly. It does so through the following steps:
--> molecules of substrate combine with the enzyme at its active site.
--> the substrate molecules combine with enzyme molecules for a short time, forming an enzyme-substrate complex.
--> New substance ( product) is formed which leaves the active site of the enzyme thereby making it free for another reaction to take place.
In conclusion, the ACTIVE SITE of an enzyme is the region of an enzyme that attaches to a substrate allowing chemical reaction to take place.
Answer:
Maintains successful genetic combinations without modification.
Explanation:
Asexual reproduction usually creates perfect copies of the parent. If the parent is genetically sound creature, then a successful genetic combination is being reproduced and maintained without any changes or modification.
All energy ends up as thermal energy, which is replenished every day by the concentrated energy from the sun.
Hope this helps!
