Explanation: mutation is a change in dna that results in overall structure changes to organisms
A spontaneous change in DNA that may lead to cellular malfunction is the most complete and accurate description of mutation.
In genetics, a spontaneous and unpredictable variation in the sequence of genes that make up the DNA of a living being that introduces specific changes is called a mutation.
This alteration, which can be hereditary, implies a modification of its characteristics.
These types of changes occur spontaneously and naturally, product of errors in the replication of the genome during the phases of cell replication.
From a mutation, the living being can develop different diseases, manifest changes in its organism or hereditary defects.
Despite of this, mutations are key to sustaining high genetic variability, promoting adaptation and evolution (even creating new species in the long run).
Therefore, we can conclude that a spontaneous change in DNA that may lead to cellular malfunction is the most complete and accurate description of mutation.

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.

Identify the model that best represents the plasma membrane of a hypothetical cell that exists in a nonaqueous environment and whose eytosol is similar to that of an animal cell. Provide TWO pieces of reasoning to support your identification.
Answer:
The models are missing in the question. The models along with the question is provided in the attachment below.
The answer is : Model A represents the Plasma membrane.
Explanation:
According to the question, model A represents the plasma membrane. The reasons are :
(a). In the model A, the bilayers consists of two leaflets of the amphipathic lipid molecules. Here the polar head groups is in contact with the intra cellular or the extra cellular non aqueous phase, where the non polar tails are facing each other constituting the hydrophobic interior of the membrane.
(b). Lipid are not rigid as well as static structure. In the lipid bilayer, the lipid molecule are able to rotate around their axis freely and diffuse laterally with each leaflet.
(c). The plasma membrane acts as the selective plasma membrane.

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.

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.

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
