Jenny is most likely seeing sleet dued to the fact it must be 32 degrees Fahrenheit to freeze and turn into a solid snow/ ice.
Answer:
c. A single enzyme typically reacts with many different substrates.
Explanation:
Enzymes are proteins that have catalytic activity and they are specific. This means that a single enzyme has only one specific substrate. They act as a "lock and key" complex, so one substrate activates to one enzyme.
Also, enzymes accelerate the rate of a reaction by lowering its activation energy. Finally, they can act in an aqueous environment, so the answer is c.
The correct answer is C. Mitosis produces 2 genetically identical diploid cells, while meiosis produces 4 genetically unique haploid cells.
Mitosis is where a parent cell duplicates its genetic information before dividing into 2, therefore, the daughter cells from mitosis are completely identical to their parent cell and the other daughter cell, and we call the cells which has complete genetic information as diploid. Mitosis is very useful in repairing, growth, asexual reproduction etc.
Meanwhile, meiosis involves 2 times of division. The parent cell first duplicates its genetic information, but then swapping them, and divide. 2 new cells are produced. Then these 2 cells are further divided but without duplicating the genetic material. Therefore, this results in 4 genetically different cells. We call them haploid, as they only have half of the chromosomes from their parent, which is the opposite of diploid. Meiosis is important in producing sex cells.
The best answer among the choices given is option B. The purpose of an experiment is to compare results with a hypothesis. A hypothesis is defined as a theory or idea that has not yet been proved. In order to turn this into a fact, scientific method should be done and the data obtained is analyzed whether it speaks the truth of the hypothesis.
