Answer:
DNA is made up of molecules called nucleotides.
Its unique structure enables the molecule to copy itself during cell division. When a cell prepares to divide, the DNA splits down the middle and becomes two single strands. These single strands serve as templates for building two new DNA molecules - each a replica of the original DNA molecule.

Answer:
The matrix is the innermost compartment of a mitochondrion . Here, the
the Krebs cycle occur(s), breaking down pyruvic acid into carbon dioxide in a series of reactions.
Explanation:
The innermost compartment of a mitochondrion is filled with a matrix. It is the site for the Krebs cycle. Here the pyruvic acid is broken down into carbon dioxide.
What is the Krebs cycle?The primary source of energy for cells and an essential component of aerobic respiration is the tricarboxylic acid (TCA) cycle, sometimes referred to as the Krebs or citric acid cycle. The cycle converts the acetyl coenzyme A (acetyl CoA) chemical energy into the reducing force of nicotinamide adenine dinucleotide (NADH).
The TCA cycle is a component of the broader glucose metabolism, which involves the oxidation of glucose to produce pyruvate, which is then further oxidized and reaches the TCA cycle as acetyl-CoA.
The cycle's half of intermediates also serves as the starting point for pathways that lead to significant molecules such as fatty acids, amino acids, or porphyrins. The integrity of the cycle is compromised and the cycle ceases to operate when any of these intermediates are so diverted. Only if the deflected intermediate or a succeeding intermediate that contributes to oxaloacetate can be replaced by anaplerotic (refilling) processes can vital energy production be restarted.
Therefore, the innermost compartment of a mitochondrion is filled with a matrix. It is the site for the Krebs cycle. Here the pyruvic acid is broken down into carbon dioxide.

Suspended in the fluid stroma of chloroplasts are
a.
cristae that provide energy.
numerous mitochondrial membranes.
b. stacks of thylakoids called grana. d. organelles called eukaryotes.
Stacks of thylakoids called grana are suspended in the fluid stroma of chloroplasts. Therefore, option (B) is correct.
Plants and other chloroplast-containing organisms transform sunlight into chemical energy through photosynthesis. The fluid stroma in plant cells' chloroplasts helps this process. The gel-like stroma surrounds the thylakoid membranes.
Chlorophyll-containing chloroplast thylakoids are membrane-bound. Light-dependent processes, the first stage of photosynthesis, collect light energy with these pigments. Grana boost light absorption by stacking thylakoids
In light-dependent reactions, thylakoid membrane chlorophyll molecules absorb light energy. ATP and NADPH, which are needed for the next stage of photosynthesis, are produced from this energy.
The fluid stroma around the thylakoid membranes includes enzymes, chemicals, and ions for dark processes and the Calvin cycle. ATP and NADPH from thylakoids convert carbon dioxide into glucose and other organic molecules in the Calvin cycle. Therefore, option (B) is correct.

What are the three types of ecological pyramids? Explain how each type of pyramid
models energy and matter in ecosystems.
Answer: The three types of ecological pyramids include the pyramid of number, which shows the number of individual organisms that exist at different trophic levels; the pyramid of biomass, which tell us the amount of living tissue or the total mass of organisms within each trophic level; and the pyramid of energy, which indicates the amount of energy at each trophic level and the actual role of each organisms in the process of energy transfer.
The three types of the ecological pyramid are-
the pyramid of numberthe pyramid of biomassthe pyramid of energyEcological pyramids show the different amounts of energy or matter present within each trophic level in a particular food chain or food web. The three different types are Pyramids of energy, biomass, and numbers.
The pyramid of number - represents the number of individual organisms that exist at various trophic levels;The pyramid of biomass- the amount of living tissue or the total mass of organisms within each trophic levelThe pyramid of energy - a graphical representation of the energy found within the trophic levels of an ecosystem.Thus, the correct answer is - Pyramids of energy, biomass, and numbers.

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:
The water pressure in the plant's vacuole is low, and without water, the chloroplasts cannot convert carbon dioxide to glucose during photosynthesis.
Explanation:
The water pressure in the plant's vacuole is low, and without water, the chloroplasts cannot convert carbon dioxide to glucose during photosynthesis. The water pressure in the plant's ribosomes is low, and without water, the chloroplasts cannot convert carbon dioxide to glucose during photosynthesis. The water pressure in the plant's vacuole is low, and without water, the mitochondria cannot convert carbon dioxide to glucose during photosynthesis. The water pressure in the plant's ribosomes is low, and without water, the mitochondria cannot convert carbon dioxide to glucose during photosynthesis.The correct answer would be that the water pressure in the plant's vacuole is low, and without water, the chloroplasts cannot convert carbon dioxide to glucose during photosynthesis.
Photosynthesis generally requires water as one of its reactants in the formation of carbohydrates for plant nutrition.
[tex]6CO_2 + 6H_20 --> C_6H_1_2O_6 + 6O_2[/tex]
The process takes in the chloroplast of green plants. Without adequate water which is usually stored in the vacuoles of plant cells, the conversion of water to carbohydrates would reduce or cease totally.

A. The water pressure in the plant's vacuole is low, and without water, the chloroplasts
cannot convert carbon dioxide to glucose during photosynthesis.

B. The water pressure in the plant's ribosomes is low, and without water, the chloroplasts

C. The water pressure in the plant's vacuole is low, and without water, the mitochondria
cannot convert carbon dioxide to glucose during photosynthesis.
D. The water pressure in the plant's ribosomes is low, and without water, the
mitochondria cannot convert carbon dioxide to glucose during photosynthesis.
With which cellular process are ribosomes directly involved?
The correct option is C.
Explanation:
When a plants vacuole has no pressure and water, the leaves and stems will drop because vacuole is an organelle that serve as storage for food nutrients and water . When a plant has no water for a long period of time, the vacuole will lose water, which will make the cell to lose shape, and the leaves and stems will wilts and drop ,and this make the mitochondria not to be able to convert chemical energy in glucose using carbondioxide and water to Energy or ATP because there is no supply of water or there is water lose.

While frying some eggs on a frying pan, a friend points to the change that happens to the egg white, which contains a protein called albumin. Your friend explains that if the conformation of a protein changes, it will no longer have the same properties and will lose its ability to function. Do you agree or disagree with your friend? What happened to the albumin?
EXPLAIN
Answer:
Yes because when subject to high heat, the proteins change into varying proteins, which is a chemical change. The heat causes denaturation of the albumin, which hardens and causes the change in color. The protein, when heated, untangle and they will mesh. This will trap the surrounding water, and cause the change in color.
