Answer:

The answer is D. High water pressure increases the speed of sound.

Explanation:

Due to the characteristics of seawater, the speed of sound propagation changes according to variations in temperature, salinity and pressure. The higher these water characteristics are, the higher their speed will be. if the pressure rises 10 atmospheres, when lowering 100 meters deep, the sound registers 1.8 meters per second of ascent.

What is the part of the cell cycle process by which chromosomes in a cell nucleus are separated into two identical sets of chrom
Damm [24]

Answer:

Mitotic phase

Explanation:

Cell cycle is composed of interphase and mitotic phase. Interphase is aphase of cell preparation. It is subdivided into:

  • G1 (gap 1 phase)-the cell grows and becomes larger
  • S phase- replication of DNA, duplication of centrosomes
  • G2 (gap 2 phase)-proteins and oranelles are made

Mitotic phase is phase of cell division, chromosomes are separated, daughter cell get identical sets of chromosomes. It is followed by cytokinesis-separation of cytoplasm. Stages of mitosis are:

  • prophase-condensation of chromatin into chromosomes,  the nuclear envelope breaks down, mitotic spindle formation
  • metaphase-the chromosmes line up (metaphase plate)
  • anaphase-the siste chromatides move toward opposite cell poles
  • telophase-the nuclear envelope forms again, cell division is almost complete

Choose ALL of the phases of matter listed<br> that are able to flow:<br> gas<br> liquid<br> solid
IrinaK [193]

Answer:

- gas

- liquid

Explanation:

     Part of the definition of gases and liquids is the ability to flow, so this answers your question.

     Why does this not apply to solids? The cells in a solid are closer together with less room for movement, so they do not "flow" like gasses or liquids. You can think of the device you are asking this question on versus the water in the ocean.

<u>Note</u>: Gas can still flow, but it does not flow the same as water. It depends on what you are being taught for if gas flows or not.

-> Liquid flows from high to low only, while gas can flow in all directions

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

     ★ Also please leave the rating you think I deserve (It helps other users as well as myself)

The breakdown of food via enzymatic reactions is known as __________.
r-ruslan [8.4K]
I believe you're looking for "chemical digestion".

Chemical digestions is where food that we ate is digested into simpler and soluble molecules that can be absorbed by our body. Enzymes are used as a catalyst to speed up the reaction.

One example is the digestion of lipids. Enzyme named lipase is used to speed up the digestion of lipids into 3 fatty acid molecules and 1 glycerol. This way, our body can absorb these simple molecules, and use them in order to make our body function.

On the other hand, physical digestion does not include enzymes, such as chewing in our mouth, therefore, don't mix them up!
