The following figure shows a plant cell immediately after it has been placed in distilled water (A) and a plant cell that has been in distilled water for several minutes (B). Determine whether each of the following statements is true or false based on this figure.
Drag True or False to the end of each statement.
Plant cell A has lower water potential than cell B.
Plant cell B is isotonic to the fluid in the beaker.
Plant cell B's water potential increased due to an increase in solutes inside the cell.
Plant cell B is at equilibrium with the fluid in the beaker.
Plant cell A has higher water potential than cell B.
Plant cell A is at equilibrium with the fluid in beaker.
Answer:
Plant cell A has lower water potential than cell B. True
Plant cell B is isotonic to the fluid in the beaker. True
Plant cell B's water potential increased due to an increase in solutes inside the cell. False
Plant cell B is at equilibrium with the fluid in the beaker. True
Plant cell A has higher water potential than cell B. False
Plant cell A is at equilibrium with the fluid in beaker. False
Explanation:
Plant cell A has lower water potential than cell B. True
This statement is true because the water potential of A is -2 bars while that of B is zero bars.
Plant cell B is isotonic to the fluid in the beaker. = True
Isotonic solutions have equal water potential. Since the water potential of distilled water is zero and that of plant cell B is zero as well, plant cell B is isotonic to the fluid in the beaker.
Plant cell B's water potential increased due to an increase in solutes inside the cell = False.
An increase in solute inside the cell doe not increase water potential but rather reduces it.
Plant cell B is at equilibrium with the fluid in the beaker. = True
Plant cell B is at equilibrium with the fluid in the beaker because its water potential is zero since the negative solute potential is counterbalanced by the positive pressure potential.
Plant cell A has higher water potential than cell B = False.
Plant cell A has a lower water potential of -2 bars while plant cell B has a higher water potential of zero.
Plant cell A is at equilibrium with the fluid in beaker. = False.
Plant cell A is not at equilibrium with the fluid in the beaker, rather due to its negative water potential, water will move into the cell.

Explanation:
There is not a problem with the model. The atoms are tightly compacted to get, so if you were to cut it in half the split would also be smooth and straight. For example, a grain of salt is rough on the outside, but when you cut it in half the split is smooth. It is the same with the atoms in the model.
Which statement best explains the relationship between producer and consumers in terms of energy?
A. Consumer produce glucose that producer's use for energy
B. Consumers convert carbon dioxide into energy
C. Consumers provide energy for producer to undergo aerobic respiration
D. Consumers convert glucose from producers into ATP
Answer:
C
Explanation:
Consumers can't convert glucose, they don't take in carbon dioxide, and they can't produce Glucose, therefore it has to be C
The best explaining statement is that consumers convert the glucose from producers into ATP. So the correct option is D.
What is aerobic respiration?The conversion of fuel, such as fats and carbohydrates, into chemical energy, is known as aerobic respiration. Anaerobic respiration, in contrast, doesn't require oxygen.
All cells employ respiration to convert fuel into energy that can drive cellular functions. Adenosine triphosphate (ATP), a byproduct of respiration, is a molecule that utilizes the energy contained in its phosphate bonds to drive chemical processes. It is frequently referred to as the cell's "money."
Anaerobic respiration is less effective than aerobic respiration and takes significantly longer to create ATP. This is so because the chemical processes that produce ATP make great use of oxygen as an electron acceptor.
Therefore the correct option is D.

Which of the following statements is true of chemical bonds?
Both ionic and covalent bonds involve electrons in the innermost shell.
Covalent bonds share electrons between two atoms.
An atom involved in an ionic bond has an equal number of electrons and protons.
Salts are covalently bonded.
The atoms in a molecule of water (H2O) are bonded together with ionic bonds.
The true statement of chemical bonds is covalent bonds share electrons between two atoms.
A covalent bond is a type of interaction that involves one or more pairs of electrons (e-) being shared between two atoms.In a covalent bond, shared electrons are jointly attracted by both atomic nuclei.A double covalent bond occurs when four electrons are shared between two atoms, whereas a triple covalent bond involves the sharing of six electrons.An ionic bond is when one atom gives its electron to another atom, e.g., during the formation of sodium fluoride.In conclusion, covalent bonds share electrons between two atoms.

describe peptide bonding and provide an example
Answer:
A peptide bond is a covalent bond formed between two amino acids. Living organisms use peptide bonds to form long chains of amino acids, known as proteins. Proteins are used in many roles including structural support, catalyzing important reactions, and recognizing molecules in the environment. A peptide bond is therefore the basis of most biological reactions. Forming peptide bonds is a requirement for all life, and the process is very similar in all forms of life.
Explanation:
Answer:
peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of other molecules.

Water only moves once the wave's energy starts to collapse true or false ?
Answer:
When particles in water become part of a wave, they start to move up or down. This means that kinetic energy (energy of movement) has been transferred to them. As the particles move further away from their normal position (up towards the wave crest or down towards the trough), they slow down.
Explanation: false because water only moves when the waves energy does not collapse

what is the process of water moving down through the soil called?
A. evaporation
B. percolation
C. condensation
D. transpiration
Answer:
The answer is B the girl is wright
The process through which the water moves down in the soil is known as percolation. Therefore, option "B" is correct.
What is percolation?The slow movement through a surface that has tiny openings or spaces in it. The tiles prevent water from percolating by sealing off the soil. The value of soil as a crop soil is largely determined by its rate of infiltration which is the rate at which water enters a soil) and percolation (the rate at which water moves through a soil.
These two variables impact the development of normal untamed life environments and the nature and speed of flooding in a given region. The process occurs gradually.
Therefore, the process of percolation is a physical process that helps in water drainage.
