What does "enzymes are organic catalysts" mean?
Answer: Catalyst. Any molecule that will increase the rate of a chemical reaction, does not participate directly in the reaction and therefore is reusable, and does not supply the energy for the reaction (heat or ATP does). Enzymes work on one reactant, called a. Substrate.

Hope this helps.
Have a good night ma´am/sir.
Be safe!
"Enzymes are organic catalysts" refers to the fact that enzymes are an organic class of biological molecule that act as catalysts in chemical reactions.
Catalysts are compounds that speed up chemical reactions without being consumed or changed in any way. In living organisms, enzymes are essential for many biochemical processes, including the breakdown of food during digestion, the synthesis of molecules, and the facilitation of cellular processes. Enzymes help maintain vital biochemical processes, maintaining the fundamental activities of life, by reducing the activation energy required for a reaction.

In parts of the Northern Hemisphere grasslands, the spring growing season is becoming two weeks longer than in the second half of the 20th century. The spring growing season is now coming earlier in both hemispheres. Based on the above statement and the following graph, what conclusion can be made regarding temperature?
Answer:
Natural Earth cycles result in increased temperatures
Explanation:
By temperature looking te the graph we can see that there is a soft increase in temperature from 1880- 1940. It seems that from 1940-1980, the temperature was stable, but since 1980 there is a noticeable temperature increase, until the year 2000. By year there are increases and decreases in temperature, which correspond to the different seasons and temperature cycles over the year, but in a general vision, the temperature is obviously increasing with the pass of years.
According to the statement, the spring growing season is becoming longer than in the second half of the 20th century, and it is coming earlier. This is reflected in the graph from the year 1980 to 2000.
According to the graph and the statement, we could estimate what is going to happen in the next years is there is no change. Although, we can not predict it for sure.

Meiosis is a type of cell division that produces:
A. Zygotes
B. Chromosomes
C. DNA
D. Gametes
Answer:
B. Chromosomes
Explanation:
This process is required to produce egg and sperm cells.
Meiosis is a type of cell division that produces: Gametes.
Meiosis is called a form of reproduction of cells, specifically, it allows a diploid cell to divide twice consecutively, generating four haploid cells (with half the number of chromosomes each).
This type of cell division is key to sexual reproduction, since through meiosis organisms produce their gametes or reproductive cells.Haploid cells are the gametes or reproductive cells that are involved in sexual reproduction, that is, they are the sperm (male gametes) and the ovules (female gametes).When a sperm and an egg fuse with each other during fertilization, each of them contributes half of the genetic load of the new individual.Thus, both haploid sets of each gamete combine to form a complete diploid set, which is the genome of the newly formed individual.Therefore, we can conclude that meiosis is an essential process prior to sexual reproduction, since gametes are formed during this process.

Aquarium salt water is prepared to a salinity of 30 ppt (parts per trillion) by dissolving 3.26 kg of salt into 114 L of water. If you wanted to make 4,000 mL of salt water at the same salinity, how many grams of salt will you need?
Answer:
114 gram of salt is required.
Explanation:
Below are the following given data in the question:
Prepared salinity water = 30 ppt
Weight of salt used = 3.26 kg
The volume of water = 114 L
Below is the calculation.
4000 mL = 4000/1000 = 4L
Let the used = x kg
3.26/114 = x/4L
Now solve for the x.
x = 0.114 kg or 114 gram

Describe how you might figure out if something was made out of cells.
Answer:All living organisms are composed of cells, from just one to many trillions, whose details usually are visible only through a microscope.
Explanation:
To determine if something is made out of cells, several approaches can be employed, including microscopic and biochemical assays for physical and chemical assessments.
Visual inspection using a microscope can reveal the presence of cell-like structures, such as membranes, nuclei, or organelles. Staining techniques, such as fluorescent dyes or immunohistochemistry, can further enhance the visibility of cellular components.
DNA analysis can also be conducted by extracting genetic material from the sample and performing sequencing or polymerase chain reaction (PCR) to detect DNA specific to cells.
Biochemical assays can be used to identify cellular components, such as proteins or enzymes, which are characteristic of cell composition.

Does the shape of molecule affect the chimecal bond?
Answer:
no shape of molecules doesn't affect the chemical bond
Answer:
There is a sharp distinction between ionic and covalent bonds when the geometric arrangements of atoms in compounds are considered. In essence, ionic bonding is nondirectional, whereas covalent bonding is directional. That is, in ionic compounds there is no intrinsically preferred direction in which a neighbour should lie for the strength of bonding to be maximized. In contrast, in a covalently bonded compound, the atoms adopt specific locations relative to one another, as in the tetrahedral arrangement of hydrogen atoms around the central carbon atom in methane, CH4, or the angular arrangement of atoms in H2O.

The question is:
"Based on the law of conservation of energy, which statement is false?
(A). Energy is lost when machines don't work right.
(B). We can't add more engry to rhe universe.
(C). We can't destroy energy that exists in the universe.
(D). Engrey changes from one form to another.
Thanks- Caitlyn
Answer:
(A). Energy is lost when machines don't work right.
Explanation:
The false statement from the choices is that energy is lost when machines do not work right.
The law of conservation of energy states that "energy can neither be created nor destroyed , they can only be converted from one form to another. "
Option B is clearly covered by the statement of the law. All the energy of the universe is already created. Energy cannot be destroyed tallies with the Option C. Energy is transformed from one form to another validates the fourth choice. We can covert from thermal to mechanical energy and vice versa.The only odd choice is that energy is lost when a machine doesn't work right.
