Answer:
mitochondria and chloroplasts can not survive outside of the cell
Explanation:
The statement that mitochondria and chloroplasts cannot survive outside of the cell is not a supporter of the endosymbiotic theory. So the correct option is A.
What is the endosymbiotic theory?
It's possible that eukaryotic cells originated when several cell types fused to form one. They started coexisting in what are known as symbiotic partnerships. The endosymbiotic theory describes how this may have occurred. One creature that resides inside of another is known as an endosymbiont. Your own cell and all other eukaryotic cells are animals formed of other species' components.
Both the chloroplast and the mitochondrion are organelles that were formerly free-living cells. They were prokaryotes that were ensconced within other cells (host cells). They may have become a part of the other cell by being eaten (a process known as phagocytosis), or they could have been parasites living inside the host cell.
The inner cell lived and flourished with the host cell rather than being ingested by or destroying it. It resembles a landlord and a renter in certain ways. The organelle pays rent by producing energy that the host cell may consume, and the host cell offers a cozy and secure home.
The organelle and the host cell have developed together throughout time as a result of this long-ago event. The two are now inextricably linked. Even while they now work as a single organism, if we look closely, we can still see traces of the organelles' former lives as free-living entities.
Therefore the correct option is A.

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
Answers
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

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.

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? *
Answers
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.

As rocks erode from Earth's surface, they are replaced by the process of uplift. The correct option is B.
What is rock erosion?Rock erosion is a natural process that occurs due to the force of wind and water. Rock erosion occurs on the rocks nearby water bodies and high rocks, which are cut down by flowing wind.
The uplift process takes place due to the movement of tectonic plates. When the two plates collide and move upwards, it is called uplift.

Answers
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.

B)
Explanation:
Several groups of students were comparing the processes of mitosis and meiosis. Each group came up with a different answer for how the two processes are different.
Mitosis- growth and repair one cell division 2 genetically identical diploid cells
Meiosis- produce gametes, two cell division, 4 genetically different haploid cells
Hope this helps :)
The group that is correct regarding mitosis and meiosis is group 2 as they said that mitosis is involved in the growth and repair of cells and undergoes cell division once, while meiosis is involved in reproduction through fusion of gametes and undergoes cell division twice. The correct option is B.
What is cell division?Type of cell division by which a parent cell divides into two or more daughter cells when a parent cell divides into two or more daughter cells. Cell division is typically part of a larger cell cycle.
Cell division occurs in two stages namely mitosis and meiosis. When most people say cell division, they're referring to mitosis, the method by which new body cells are formed.
Meiosis is the process by which egg and sperm cells are formed. Mitosis is a necessary process for life.
The group 2 is stating the same that mitosis is the division for growth and repair and is done in only once, and meiosis is the process of gamete formation and occurs twice.
Thus, the correct option is B.
