What is the total of O2 + CO2

Answers

Answer 1

Answer:

Answer:

The total of O2 + CO2 is not a mathematical expression that can be added together.

O2 and CO2 represent different chemical compounds: O2 refers to oxygen gas (two oxygen atoms bonded together), and CO2 refers to carbon dioxide (one carbon atom bonded to two oxygen atoms).

In chemistry, we do not add or combine the formulas of different compounds in the same way we add numbers. Instead, we use chemical reactions and equations to understand how elements and compounds interact and form new substances.

How many and what type of chromosomes would be expected in a karyotype of a human male? (1 point) 22 pairs of autosomal chromosomes and 2 Y chromosomes 23 pairs of autosomal chromosomes and 2 Y chromosomes 22 pairs of autosomal chromosomes, 1 X chromosome, and 1 Y chromosome 23 pairs of autosomal chromosomes, 1 X chromosome, and 1 Y chromosome

Answers

Remember there are 46 chromosomes in a (normal) human nucleus, which consists of 23 pairs of chromosomes.

Of these, one pair are the sex chromosomes.

In females, the sex chromosomes are XX

In males, the sex chromosomes are XY

So the karyotype of a human male would consist of 22 pairs of autosomal chromosomes, an X chromosome, and a Y chromosome.

The correct answer is

C. 22 pairs of autosomal chromosomes, 1 X chromosomes, and 1 Y chromosomes

Diffusion continues until

Answers

equilibrium.
diffusion occurs due to differences in concentration of substances in different regions. then substances will naturally spread out (due to innate Brownian kinetic energy). the spreading I. e. diffusion will stop until equilibrium is achieved.
note: those substance particles are still moving due to the innate Brownian kinetic energies!

Final answer:

Diffusion is the process where molecules move from higher to lower concentration areas. It continues until a state of equilibrium is reached, at which the particles continue to move but their distribution remains constant.

Explanation:

In biological terms, diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration. This passive movement continues until it reaches a state we refer to as equilibrium. At equilibrium, there is a uniform concentration across the space, and diffusion continues, albeit without any net change, as particles continue to move randomly but their overall distribution remains constant.

During the rock cycle, rocks get broken apart by weathering, carried along by erosion, and eventually deposited in a body of water. What happens next?

Answers

After many years of pressure and possibly heat it will be compressed back into a form of rock such as sediment.

Compaction and cementation into sedimentary rock, then heat and pressure into metamorphic rock. this is correct answer

What is the useful product of glycolysis for the cell?A. NAD+

B. pyruvate

C. lactic acid

D. ethyl alcohol

Answers

Answer:

The correct answer is B. pyruvate

Explanation:

In glycolysis, glucose is oxidized to produce 2 molecules of NADH, ATP, and pyruvate. Then this pyruvate molecule is used in the Kreb cycle and gets fully oxidized into carbon dioxide and water.

This oxidation of pyruvate molecule gives rise to more NADH and FADH₂ molecule. These molecules are reduced form of energy which is used as a source of electron during oxidative phosphorylation to produce more ATP molecules.

Therefore pyruvate is the useful product of glycolysis which is utilized to give energy to the cell in the form of ATP.

10 differences between animal cells and plant cells

Answers

Answer:

Following are the difference to the given question:

Explanation:

Plant cells have a wall of a cell, while cells of animals wouldn't. Cell membranes offer plants support and shape.
Chloroplasts in plant cells do not occur, however, in animal cells. Chloroplasts allow plants can grow things via photosynthesizing.
Plant cells typically get a vacuole(s) that is one or even more big, whereas animal cells are vacuous, whether any.
Large vesicles assist shape the plant and enable food and water to be store for future use.
In animal cells, the storing function takes a smaller part and the vacuoles, therefore, are smaller.
A plant cell is square in its structural way and an animal cell is often spherical and irregular.
The cell of a plant has a vesicle in its big form which is significantly smaller than the plant cell, as well as the animal cell was the or more vacuoles. In general, a vacuole is a storage area for the cells to store water.
There is no chloroplast inside the animal cell. Chloroplast is a plant cell that produces photosynthesis from its food. The plants have a green color.
The nucleus is located throughout the cell of the plant on the other edge of the peripheral cytoplasm, while the nucleus is in the animal's core.
Plant cells store food of starch while animal cells store food of glucose.
The mitochondria in the plant are fewer and also have tube cristae, whereas the animal cells have grown in various.
