Which letters are broken down to produce energy for cells? There’s two

Answers

Answer:

C and D

Explanation:

Cellular respiration, which is the process whereby energy in form of ATP is synthesized, occurs in the MITOCHONDRIA. The products of cellular respiration (CO2 and H2O) are used as reactants by plants to produce glucose and oxygen in their CHLOROPLASTS in a process called PHOTOSYNTHESIS. The glucose and oxygen are broken down in the MITOCHONDRIA to yield energy by cells.

In this image, letters C and D represents glucose and oxygen, which are products of photosynthesis in the chloroplast. Glucose and oxygen represented by C and D are broken down to produce energy for cells in the mitochondria

Which of these best describes weathering and erosion?

A
They are tools people use to change landforms and create new ones.

Answers

the answer i believe is d

The best description of weathering and erosion should be considered as the option d. They significantly change the surface of the Earth every few days.

What is weathering and erosion?

Weathering represent the break down or the rocks should be dissolved out and the minerals should be on the earth surface.

When the rock should be split down so this process we known as the erosion transports.

Therefore, the option d is correct.

Explanation:

When water gets in the crack at the bottom and freezes, frost wedging occurs.

Frost wedging happens when water gets in crack, freezes, and expands. This process breaks rocks apart. When this process is repeated, cracks in rocks get bigger and bigger (see diagram below) and may fracture, or break, the rock.

Answers

Prokaryotic cells, which include bacteria, undergo a type of cell division known as binary fission. This process involves replication of the cell's chromosomes, segregation of the copied DNA, and splitting of the parent cell's cytoplasm. The outcome of binary fission is two new cells that are identical to the original cell.

Calculate the volume in mL of a stock solution of 100% ethanol, required to prepare 2 L of a 70% solution of ethanol in dH2O

Answers

Answer:

For example, to make 70% ethanol from 95% ethanol, take 70 mL of 95% ethanol and add enough water to bring the volume to 95 mL. You will then have 95 mL of 70% ethanol. This works for any dilution and all that is required is a large enough graduated cylinder.

When using liquid reagents, the percent concentration is based upon volume per volume, i.e. #ml/100ml. Example 2: If one wished to make a 70% ethanol solution, 70 ml of 100% ethanol would be dissolved in 30 ml of water (or the equivalent for whatever volume was needed).

A student finds a beaker containing a substance in the laboratory. The student filters the contents of the beaker and notices that a solid is left on the filter paper.
What can the student conclude about the type of matter of the original material?

Answers

Answer:

These are my answer choices so I guess it's an mixture, it's a mixture of filtration .. so its a mixture

Explanation:

(1) The original material was a mixture.

(2)The original material was a compound.

(3)The original material was either an element or a compound.

(4)The original material was either a mixture or a compound.

A beaker containing a substance is in the laboratory. Upon filtering, a solid is left on the filter paper. We can conclude that the original material was a mixture.

Filtering is a method for the separation of heterogeneous mixtures. A filter paper is placed in a funnel and the mixture is poured over it. The liquid passes the filter while the solid is retained. Since this was the situation of the student, we can conclude that the original material was a mixture. After the filtering, the student will have 2 homogeneous systems.
