The main difference that separates prokariotic organisms from eukaryotic organisms is the organisation of the genetic material. Prokaryotes have a single chromosome that isn't separated by a membrane and it's called nucleoid. Eukaryotes have multiple chromosomes that are inclosed in a nuclear envelope(nucleus).
The only organelles present in prokaryotic cells are the ribosomes(70S) which differ from the eukaryotic ribosomes(80S). Eukaryotic cells have membrane bound organelles like the mitochondrion or Golgi aparatus.

describe and explain how the rate of photosynthesis is affected by light intensity
A student observes that a plant has droopy leaves and stems and infers that the rate of photosynthesis has slowed in the plant. Which statement provides evidence to support the student’s inference?
Answer:
A. The water pressure in the plant's vacuole is low, and without water, the chloroplasts cannot convert carbon dioxide to glucose during photosynthesis.
Explanation:
Photosynthesis occurs on chloroplasts which are located on the surface of leaves. Photosynthesis is the conversion of carbon dioxide, water, and light energy to produce glucose and oxygen for plants.
The vacuoles inside the plant's cell contain stored food and absorb water through osmosis. Water in the vacuole has more solutes than water outside the vacuole. This causes the Turgor Pressure which the vacuole impacts on the plants. If the reverse becomes the case, water is lost from the vacuole causing it to shrink.
Flaccidity of the vacuole and the cell wall will cause the chloroplasts where photosynthesis occurs to shrink.
PLEASE help its a question about rocks I'm tryna score a 80
Answer: The answer is C
Explanation:
lavas cool quickly at the earth's surface and are characterized by fine-grained texture, in which the crystals are too small to be seen by the unaided eye. Very quickly cooled lavas, typically those quenched in water, will have a glassy texture. They cool too quickly to form crystals.
the other liquid waste product in cellular respiration is
Answer: During the process of cellular respiration, carbon dioxide is given off as a waste product. This carbon dioxide can be used by photosynthesizing cells to form new carbohydrates. Also in the process of cellular respiration, oxygen gas is required to serve as an acceptor of electrons.
Explanation: Hope dis helps :)))))

Explanation:
Which refers to the sum of all the forces that act upon an object?
A. net force
B. absolute force
C. balanced force
D. positive force
Answer:
Net force
Explanation:
Net force is the vector sum of forces acting on a particle or body. The net force is a single force that replaces the effect of the original forces on the particle's motion. It gives the particle the same acceleration as all those actual forces together as described by the Newton's second law of motion.
Answer:
net force

A human liver cell has a different size and shape from a human muscle cell. What is the best explanation for these differences?
A. The cells perform different functions.
OB. One of the cells is used to reproduce more cells while the other is not.
OC. One type of cell develops into the other type of cell.
OD. One of the cells must have come from another species.
Answer:
A
Explanation:
A human liver cell would have a different size and shape from a human muscle cell because they perform different functions in the body.
The shape a cell would assume and its size depends on the function the cell performs. The functions of the liver in the body of humans differ greatly from the functions of muscles. While the former helps in detoxification, deamination, digestion, etc., the latter helps in support, movement, etc.
The correct option is A.
A human liver cell has a different size and shape from a human muscle cell because the cells perform different functions.
CELL:
Cell is the basic and fundamental unit of life. It is the simplest level of organization of an organism. Cells contain organelles that help them perform specific functions. Organs are made up of numerous cells. Similar cells perform similar functions while dissimilar cells perform dissimilar functions. Therefore, a human liver cell has a different size and shape from a human muscle cell because the cells perform different functions.Learn more at: https://brainly.com/question/22663686?referrer=searchResults

What are two ways in which cells use the energy temporarily stored in ATP?
Answer: Energy provided by ATP is used in active transport, to contract muscles, to make proteins, and in many other ways
The two main ways in which cells use the energy temporarily stored in the form of ATP is in active transport, and to make proteins.
What is Active transport?
Active transport is the movement of molecules, ions, solutes, solvents against the concentration gradient. The flow of material takes place from the region of their lower concentration to the region of their higher concentration. The transport is against the gradient and hence requires energy to proceed which is given by ATP.
ATP is required to synthesize proteins in the ribosomes of the cell through the process of translation. This is a highly energy-consuming energy and thus required large amount of ATP.

The four classes of macromolecules are carbohydrates, proteins, nucleic acids, and lipids. These biomolecules can also be referred to as polymers. In turn, we will discuss how these four classes of macromolecules are synthesized in the cell from their constituent building blocks or monomers.
Explanation:
Antibody Classes. Antibodies can be divided into five classes—IgM, IgG, IgA, IgD, IgE—based on their physiochemical, structural, and immunological properties. IgGs, which make up about 80 percent of all antibodies, have heavy chains that consist of one variable domain and three identical constant domains.
Answer:
Antibodies are proteins. An antibody (Ab), also known as an immunoglobulin (Ig), is a large Y-shape protein produced by plasma cells that is used by the immune system to identify and neutralize foreign objects such as bacteria and viruses

Which of the following solutions would have solute concentration that is lower than the concentration found inside the cell
