Answer:
If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, the relative concentrations of solute and water are equal on both sides of the membrane. There is no net water movement, so there is no change in the size of the cell.

How to do research on the six characteristics of living things
In an experiment, a scientist isolates mitochondria from living cells and suspends them in two different buffered solutions. One solution is maintained at pH 4, while the other solution is maintained at pH 9. The
scientist finds that mitochondria in the solution at pH 4 continue to produce ATP but those in the pH 9 solution do not
The results of the experiment can be used as evidence in support of which of the following scientific claims about mitochondrial activity?
Mitochondria in a cell free environment are unable to convert thermal energy into ATP.
The electron transport chain pumps electrons from the cytosol to the mitochondrial matrix,
CATP production in mitochondria requires a hydrogen ſon gradient that favors movement of protons into the mitochondrial matrix.
D
ATP synthase molecules change their orientation in relation to the proton gradient across the mitochondrial membrane.
Answer:C
Explanation:
The scientific claim 'ATP production in mitochondria requires a hydrogen ion gradient that favors the movement of protons into the mitochondrial matrix' SUPPORTS mitochondrial activity (Option C).
Cellular respiration is defined as a group of metabolic reactions by which cells can generate ATP (the energy coin of the cell), by using oxygen and the energy released in the chemical bonds of foods (e.g., glucose).Cellular respiration has three main types of reactions: glycolysis, the acid citric cycle and oxidative phosphorylation.Glycolysis occurs in the cytoplasm, whereas the citric acid cycle and oxidative phosphorylation occur in the mitochondria.During oxidative phosphorylation, the movement of electrons through a series of carriers is coupled to the generation of an electrochemical proton (H+) gradient across the inner mitochondrial membrane.Subsequently, this proton (H+) gradient is then used to generate ATP by using an ATP synthase.In conclusion, the scientific claim 'ATP production in mitochondria requires a hydrogen ion gradient that favors the movement of protons into the mitochondrial matrix' SUPPORTS mitochondrial activity (Option C).

how do 2 siblings from the same parents look different to each other
Answer:
After all, kids get their genes from the same parents. But brothers and sisters don't look exactly alike because everyone (including parents) actually has two copies of most of their genes. And these copies can be different. Parents pass one of their two copies of each of their genes to their kids.

Converting Solar EnergyExplanation:
In your own words, define or describe what you
already know about photosynthesis?
Answer: Okay so Photosythesis is the process used in most plants (except carnivorus plants) when the plant uses its chroloplasts (cells only plants have) to convert sunlight into sugar which makes food for the plant so it can live without having to hunt for food.
Explanation:
I hope this helps sorry if it doesn't :(
Have a good day :)
Stay motivated :)
Answer:
Photosynthesis is the process used by plants, algae, and certain bacteria to convert the energy from sunlight (or other usable light sources) into chemical energy. Chemical energy is the energy these organisms use for different metabolic processes. During this process, they take in the carbon dioxide produced by all breathing organisms and release oxygen, which we breathe in once again, into the atmosphere.

In the box provided explain why living organisms
contain more hydrogen atoms than any other
atoms, yet 65% of a typical organism's mass is
oxygen
І
Answer:
Explanation:
Living organisms are mostly made of water. Water is a molecule made from 2 hydrogen atoms and 1 oxygen atom, H2O. Now even though there are 2 hydrogen atoms for every oxygen atom in a living organism oxygen atoms are much heavier than hydrogen atoms. Hydrogen atoms are more than 15 times lighter than oxygen atoms and this is why they can be fewer atoms of oxygen in the body but they will still represent a lot of its weight.
Answer:
The living species comprise more number of hydrogen atoms in comparison to any other atoms, still 65 percent of the usual organism's mass is oxygen. The prime reason for this is that an atom of oxygen comprises sixteen times more mass in comparison to a hydrogen atom.

Sam wished to investigate how fertilizer run-off affects the growth of algae in freshwater lakes and streams. He set his experiment up as follows. He placed 900 ml of water into each of five 1000 ml glass beakers. To each beaker, he added 5 ml of water from an aquarium which contained a large concentration of algae. The beakers were placed under a lamp which was on a timer to provide 12 hours of light each day. Liquid fertilizer was added to the beakers in the following amounts.
Each week, a random sample from each of the beakers was examined under a microscope to get a count of the number of algal cells present.

Which researcher proposed that dreams are a chance for problem solving? A. Sigmund Freud B. Matthew Wilson C. Rosalind Cartwright D. J. Allan Hobson
Answer:
The answer is Rosalind Cartwright.
Explanation:
A researcher who proposed dreams which are a chance for problem-solving is Rosalind Cartwright. Thus, the correct option for this question is C.
What is Problem-solving?Problem-solving may be defined as an instance of illustrating a problem that significantly determines the consequences of the problem along with identification, prioritization, and selection of alternatives for a solution; and implementing a solution.
Rosalind Cartwright was a neuroscientist who proposed the theory of dreams with respect to the chance for problem-solving. She hypothesized the complete mechanisms of dreaming which is particularly based on REM sleep. It is a way to process emotions, experienced during the day.
Therefore, a researcher who proposed dreams which are a chance for problem-solving is Rosalind Cartwright. Thus, the correct option for this question is C.

The two specific products that bromelain produces when breaking down proteins are polypeptides and amino acids.
What are proteins?Proteins are a major group of biological macromolecules composed of a linear chain of aminoacids that are linked by means of peptide bonds.
Proteins are fundamental macromolecules present in all biological systems and they can be made by one or more polypeptides in order to form molecules that exhibit primary, secondary, tertiary, and quaternary structures.
These macromolecular structures can be evidenced by the tridimensional shapes that adopt different proteins, which can be globular or fibrous.
