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.
Explanation:
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.

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.

In an effort to identify the influence of genetic factors on both Type I diabetes and Type II diabetes, researchers calculated concordance rates for monozygotic twins. Concordance rates of 30–50% have been found for Type I diabetes and concordance rates of 80% for Type II. For both kinds of diabetes, dizygotic concordance rates were about 15%. What does this information suggest concerning the relative effect of genetic and environmental factors for each type of diabetes?a) Environmental factors have no role in the occurrence of either type of diabetes.b) Type II diabetes appears to be caused by a single, unidentified gene.c) Genetic influences exert a larger role in Type II diabetes than in Type I diabetes.d) Genetic factors have little or no role in the occurrence of Type I diabetes.e) Type II diabetes is primarily determined by non-genetic factors.
The correct answer is C) Genetic influences exert a larger role in Type II diabetes than in Type I diabetes.
Explanation:
Monozygotic or identical twins share the same genes; due to this, if twins have the same diseases or there are concordance rates, it can be concluded the disease or condition is influenced by genetics.
In the case of diabetes, the concordance rate for Type II diabetes was high (80%), which proves this type of diabetes is influenced to a large extend by genetics. Similarly, in Type I diabetes genetics seem to have an influence but this is not as strong as in Type II because the rates were lower (30-50%).
Moreover, the results of dizygotic twins (twins with different genes) show diabetes is influenced by genetics because in these twins the genetics are not the same, and therefore the concordance rate is low.

"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.

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.

Which organisms release carbon dioxide as waste consumers only consumers ending D composers producers indie composers or producers only
Answer:
Producers and Decomposers
Explanation:
The organisms that release carbon dioxide as waste are consumers and decomposers. The correct option is B.
What are consumers and decomposers?Consumers are organisms that consume this food from plants like animals. And decomposers are organisms that convert complex food material into simple ones, like bacteria.
When an animal breathes out or exhales, waste carbon dioxide is released. Decomposers release carbon dioxide as they disintegrate dead plants and animals. Plants can use all the carbon dioxide produced in the atmosphere as a result of these activities.
Producers are only eaten by consumers before being broken down by decomposers. To restart the cycle, producers are fed with this dead material.
Therefore, the correct option is B. consumers and decomposers.

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.
