Meiosis is a unique type of mobile department of germ cells in sexually-reproducing organisms that produces the gametes, which includes sperm or egg cells. It includes two rounds of division that in the end bring about 4 cells with only one reproduction of each chromosome.
In cellular biology, mitosis is part of the cellular cycle wherein replicated chromosomes are separated into two new nuclei. Cellular division via mitosis gives upward thrust to genetically same cells in which the overall variety of chromosomes is maintained. Consequently, mitosis is likewise referred to as equational department.

What is substrate?The molecule that an enzyme reacts with is known as the substrate in biochemistry. Catalyzing chemical reactions involving the substrate is done by enzymes (s). In the case of a single substrate, the substrate forms a bond with the enzyme's active site, resulting in the formation of an enzyme-substrate complex. The surface on which an organism (such as a plant, fungus, or animal) lives is referred to as a substrate. Animals, biotic or abiotic materials, and both can make up a substrate. An animal that lives on top of encrusting algae on a rock, for instance, may use the algae as its own substrate. Substances that the enzymes react with are referred to as substrates in biochemistry. The foundation to which an immobile substance is bonded is referred to as the substrate in ecology.

Answer:
C. Atom Y
Explanation:
when calculating charge, the "Number of Neutrons" doesn't matter because neutrons have no charge. (so you can ignore the neutrons section for this question)
also, protons have a positive charge, and electrons have a negative charge
to solve this problem, add the charges of the protons and neutrons together to see if the number ends up positive (because question is looking for positive charge)
for Atom W: [tex]3+(-3) = 0[/tex], so no, this isn't the answer. 0 is neutral charge
for Atom X: [tex]53 + (-53) = 0[/tex], this isn't the answer either. 0 is neutral charge
for Atom Z: [tex]1+(-1)=0[/tex], nope, 0 is neutral charge
for Atom Y: [tex]55+(-54) = 1[/tex], yay this is it, 1 is positive which indicates positive charge.

Summarize at least 2 advantages of CRISPR.
CRISPR is simple and powerful compared to the rest of technologies used for editing genome. It is simple because it has the ability to point the definite DNA sequences which is facilitated by an easy to synthesize regulated strand of RNA. It is powerful because it let on an immediate target and remove and improve all deterioted DNA sequence present in a gene.
Answer: See Below
Explanation:
1. CRISPR utilizes a guide RNA (gRNA) that directs the function of a CRISPR protein effector to a specific target gene of choice, providing a versatile programmable platform. The targeting sequence of the gRNA is ~20bp therefore off-target genome editing is less common making it advantageous over most other restriction endonucleases.
2. CRISPR has increased versatility in many aspects and allows for a wide variety of applications in terms of genome editing. For example, The nickase version of the Cas protein induces only a single stranded cut thus opening up opportunities for altered editing. The Cas12a or Cpf1 version of the Cas protein cuts to form 5' sticky ends. And finally for the last example, the Cas protein has been bound to a reverse transcriptase and has shown efficacy in a technique called "Prime Editing" which has an altered gRNA that provides a primer binding site and template for full base insertions, deletions, and combinations of the two.

A substance's mass and volume must be taken into account when determining its density.
What is the relationship between a substance's mass and volume known as?mass per unit volume of a solid substance; density. The most popular density measurement is grams per cubic inch.
Which technique can we use to calculate the substance's mass or volume?A balance may be used to measure mass for both solids and liquids; however, separate techniques must be employed for solids and liquids to calculate volume. Glassware, like a graduated cylinder as well as a volumetric flask, can be employed to measure the volume of a liquid since liquids can flow and adopt the geometries of their vessels.
What connection exists between mass volume as well as density as a characteristic of matter?Mass and volume have a direct relationship with density. In fact, it explains how precisely the two are related to one another. By dividing an object's mass by volume, we may get its density. It would be considered to be of low density if the mass had a high volume but a tiny mass.

The image shows the rate of an enzyme reaction under conditions of no inhibition, competitive inhibition, and noncompetitive inhibition as reactions labeled uninhibited, A, and B. Which of the following best explains what has occurred in the enzyme reactions?
Reaction B shows competitive inhibition, where increased substrate competes with inhibitors for the active site.
Reaction A shows noncompetitive inhibition, where increased substrate competes with inhibitors for the active site.
Reaction A shows competitive inhibition, where increased substrate does not affect the enzyme’s binding with the inhibitor.
Reaction B shows noncompetitive inhibition, where increased substrate does not affect the enzyme’s binding with the inhibitor.
The option that best explains what has occurred in the enzyme reactions is option C: Reaction A shows competitive inhibition, where increased substrate does not affect the enzyme's binding with the inhibitor.
What occurs when a non-competitive inhibitor inhibits an enzyme?Instead of affecting how much substrate binds to the enzyme, this kind of inhibition slows down the enzyme's rate of turnover. Instead of being stopped, the reaction is said to be one that is slowed down.
Therefore, the act of increasing the substrate will not be able to also increase the non-competitive inhibition. Hence option C is correct.

In a chemical reaction where 100 grams of Chemical X react completely with 50 grams of Chemical Y, how many grams of product will be formed? ( PLEASE HELPPP)
If 100 grams of chemical X and 50 grams of chemical Y completely react together, 150 grams of the product should be formed.
Law of conservation of massThe law of conservation of mass opines that in chemical reactions, the masses of participant atoms are conserved throughout the process of the reaction. Even though the forms of these atoms might change during the whole process.
Going by this law, if 1 g of atom A and 1 g of atom B, for example, chemically react to produce a compound, AB; the mass of AB must be the sum of the masses of A and B. That is, AB should be 2g.
Now to the problem at hand. 100 grams of X reacts with 50 grams of Y completely.
100 + 50 = 150 grams.
