Answer: Amino acids are organic compounds (molecules) that contain amine (–NH2) and carboxyl (–COOH) functional groups, along with a side chain (R group) specific to each amino acid.
Explanation: The variation seen in naturally occurring amino acids arises from differences in this side chain.

A)Using an example explain how enzyme and habitation exploited to control human diseases
B)Explain why the drug is poisonous to the Target organism but not to humans
Answer:
A. Rifampicin is an example of an enzyme inhibiting drug, since it acts on the bacterial RNA polymerase, preventing the transcription and synthesis of proteins, so the bacteria is not viable and a human disease is controlled.
B. The drugs have specificity by microorganisms —target organisms— which are also smaller and more susceptible, while their effect is minimal or null in human cells and are not poisonous for them.
Explanation:
Bacteria, viruses, parasites and pathogenic fungi are microorganisms capable of producing disease in humans. One of the ways to fight infectious diseases is the use of drugs called antibiotics, capable of interfering with the development of microorganisms.
Antibiotics or antibacterials are capable of preventing the synthesis of the bacterial wall or its reproduction, intervening in the synthesis of proteins. They do this through enzymatic inhibition of these processes.
Rifampicin is a drug capable of coupling itself to one of the sub-units of the RNA polymerase enzyme, changing its configuration and preventing its affinity for its substrate, the bacterial DNA. Rifampicin thus prevents the synthesis of proteins necessary for the development of the bacterium, which dies and thus manages to control an infectious disease.Drugs such as antibiotics act on specific bacterial functions —their target organism— by affecting the functions that allow them to live that allow them to live, as if they were poisoned. These same drugs have little or no effect on human cells when administered in appropriate doses. The few effects that are observed in human cells are not sufficient to kill them, but they do produce effects or secondary reactions, usually called adverse effects.How does Teresa act as a student?

Answer:
B- the cell membrane
Explanation:
Cell membranes are made up of lipids, proteins and cholesterol. These make up a selectively permeable layer that only allows for the movement of few molecules across the cell surface.
The lipid layer only allows for the passage of small non-polar molecules, while larger molecules require transport proteins to ferry other substances into the cell.

A student is investigating how substrate concentration affects the rate of an enzyme catalyzed reaction. Which three variables should be kept constant in the
setup of the student's investigation?
A temperature of the reaction
B. amount of enzyme
Camount of substrate
D. amount of product
E pH of the reaction
Answer:
A. temperature of the reaction
B. amount of enzyme
E. pH of the reaction
Explanation:
To test various theories, experiments are typically conducted under a number of different conditions. Several variables must be established when planning studies to ensure reproducibility, precision, and validity of findings.
For example, while controls are held constant, different independent variables are strictly altered and analyzed - this ensures validity and may show whether external factors affected the experiment.
In this experiment, the rate of the reaction is the dependent variable. Thus all factors that may influence the final result, such as the temperature, pH, and enzyme concentration should be kept constant.
These factors can increase the reaction rate by altering the configuration of the enzymes, providing more collision energy, and increasing the collisions between and ratio of reactants. Increasing the concentration is expected to increase the frequency of collisions between reactants and thus speed up the rate.
The three variables that should be kept constant in the setup of the student's investigation:
temperature of the reactionpH of the reactionamount of enzymeCONSTANT VARIABLE:
In an experiment, a constant variable is that variable that must be kept constant or unchanged in order not to affect the outcome of the experiment. Constant variable is also called control variable. In this experiment, a student is investigating how substrate concentration affects the rate of an enzyme catalyzed reaction.The constant variable i.e. the variable that the student should keep constant are as follows:temperature of the reactionpH of the reactionamount of enzymeKeeping these variables above constant means not allowing temperature, pH or amount of the enzyme interfere with the experimental outcome.Learn more at: https://brainly.com/question/474060?referrer=searchResults
Organelles are structures within the cell that perform important functions. Which of the following correctly matches the
organelle with its relationship to the whole cell?
Answer:
mitochondria: powerhouse of the cell
Ribosomes: the places where proteins are synthesized in our cells.
nucleus houses DNA;controls cell
Vacuole: holds waste and fluids from cell
Ribosomes: tiny organelles that contain RNA and specific proteins within the cytoplasm.
Explanation:
Organelles make up the subunits of a cell. There are numerous each with their own function.
There are various cell organelles that play an essential function these are as follow:
MitochondriaNucleusChloroplastEndoplasmic reticulumGolgi bodiesRibosomePeroxisomeWhat is the different role of cell organelles?Mitochondria: Generates energy (ATP) for the biochemical reaction.
Nucleus: Responsible for the synthesis of mRNA, rRNA, tRNA and DNA.
Chloroplast: responsible for Photosynthesis by using sunlight in plant cells.
Endoplasmic reticulum: carry Protein(RER) and lipid synthesis(SER).
Golgi bodies: play role in protein sorting, transporting and trafficking.
Ribosome: two types of ribosomes are present in the cell-free ribosome and membrane-bound ribosomes, responsible for the synthesis of protein.
Peroxisome: play role in fatty acid oxidation and metabolism.

11. Tom broke his leg. He was in a cast for six weeks. After his cast was
removed he had a hard time walking - WHY? *
Answer:
what-
Explanation:
Answer:
Well, the reason is because those muscles that he was once using every day, were suddenly on break and were not being used for the entire 6 weeks. Leading him to having some trouble walking.
Explanation:
When you don't use your muscles, they start to kind of chill out and get weaker in this case. So when you break your leg, and the doctor tells you not to put pressure on it, it is so that the bone can heal. But while your bone heals, the muscles in your leg are not able to move or do very much of anything because you can't put any pressure on them. So that is why when you take the cast off, you have to ease back into the regular motion in your leg that you had before.

Since invasive species did not co-evolve with the other species in the ecosystem where they were introduced _______. a. they can unbalance the ecosystem b. they are considered a serious environmental problem c. they lack natural predators to help control their population d. all of the above i will give brainliest
Answer:
The Answer is All of the above.
Explanation:
Hope this helps:)
Since invasive species did not co-evolve with the other species in the ecosystem where they were introduced they lack natural predators to help control their population. Thus, option D is correct.
What is Invasive species?Invasive species can be defined the species that are introduced intentionally or unintentionally in an environment. These species might adopt the environment in which they are placed or might not get involved in the environment.
Invasive species often unbalance in the ecosystem because they did not co-evolve and fit into the ecosystem as they are not controlled by the natural control like predators. This creates ecological imbalance.
An invasive species is a species that not belongs to that land where they are living and was introduced to that ecosystem naturally or deliberately to cause harm to that system as Invasive species have tendency to spread to a degree believed to cause damage to the environment, human economy or human health.
Therefore, Since invasive species did not co-evolve with the other species in the ecosystem where they were introduced they lack natural predators to help control their population. Thus, option D is correct.
