both the mass and volume of a substance must be used in calculating its
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.

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.
Therefore, according to the law of conservation of mass, the mass of the product formed would be 150 grams.

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.

Angela was instructed on a test to make an analogy, or comparison, for polymers. She writes four examples of how polymers are like pearl necklaces. She has many parts to this analogy that make sense, but one part of her analogy does not fit.
Which is the most likely error in her analogy?
The pearls are like monomers.
The thread that connects the pearls is like an ionic bond.
The entire necklace is like a polymer, or macromolecule.
Stringing the beads onto the thread is like polymerization.
ASAP
The most likely error in the analogy of Angela about polymers is that: The thread that connects the pearls is like an ionic bond.
Polymers are the organic compounds that are made from same or different kind of smaller units called monomers. If the monomers are of same type, it is a homopolymer and if the monomers are of two or more types than it is a heteropolymer.
Ionic bonds are formed between an electropositive and an electronegative atom. The atom that gains electron in a bond is electronegative and the atom that loses electron is called electropositive. Ionic bonds are very rare in polymers. Polymers are mainly composed of covalent bonds, hydrogen bonds and Van der Waals forces.

The steps of mitosis in the correct order as shown in the attached image is:
F, E, C, G, H, A, D, and BWhat is mitosis?Mitosis refers to the process of cell division in which two daughter cells are produced from a single parent cell.
During mitosis, the cell and its contents are divided into two. The chromosomes are also duplicated to ensure that the number of chromosomes in each daughter cell is diploid.
The steps of mitosis are as follows:
interphase,prophase,prometaphase,metaphase,anaphase, andtelophaseInterphase: this stage is composed of the first cell growth phase, G1, an S phase involving DNA synthesis, and the second cell growth phase, G2.
Prophase: here, centrioles move apart, chromatin is condensed and chromosomes become visible.
Metaphase: chromosomes separate to the equators.
Anaphase: sister chromatids separate and move to the opposite poles of the cell.
Telophase: sister chromatids become new chromosomes, centriole pairs form outside each of the nuclei.
Cytokinesis occurs and then the genetic material of the new daughter cells is no longer condensed.

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.

Stomata are the tiny openings present at the epidermis of leaves. We can see stomata under the mild microscope. In some of the vegetation, stomata are present on stems and different components of plants. Stomata play an crucial position in gaseous alternate and photosynthesis.
What system is stomata?
Via photosynthesis, they use sunlight and carbon dioxide to make food, belching out the oxygen that we breathe as a byproduct. This evolutionary innovation is so relevant to plant identity that almost all land flora use the identical pores — known as stomata — to take in carbon dioxide and launch oxygen.

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.
