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)

Compare and contrast the reasons cell division is important for unicellular and multicellular organisms. 2. Provide an example o
Ganezh [65]

(1)

For unicellular organisms, cell division is important for the reproduction of the population, Unicellular organism mainly use cell division, also called binary fission, for pollution growth. This is because unicellular organisms are only composed of one cell.

Multicellular organisms use cell division for growth and reproduction. Cell division causes increase in the number of cells composing the organism hence its growth in size. Cell division is also used to create gametes that are used in reproduction by fertilization.

(2)

Even in fully developed organisms, cell division is important in tissue repair. In tissue homeostasis, there is a balanced rate of cell division and cell death .  An example in muscles. Due to the stress experienced by muscle cells, they usually have a lower life span and therefore the damaged cells are often replaced with new ones by cell division. This prevents tissue wastage.

(3)

Growth factors signal the growth of a cell. They usually bind receptors on the cell surface and indicate how the cell should grow and divide base don environmental stimuli. An example is during regular exercises. Growth factors indicate that the muscle cells should divide regularly and grow bigger to accommodate the higher stress in the muscles from the workout. This is how your muscles grow bigger and stronger with more exercise.  

(4)

Differentiation of cells occurs through the silencing of some gene allowing the cell to produce particular proteins (and other biomolecules) that align with its functions in the body. This especially critical in multicellular organisms.  An example is that while al the cells in your body have the same DNA, some cells differentiate into liver cells while others into lungs, stomach, heart, and etcetera.

What happens when cells grow out of control?
Alexus [3.1K]
Answer: Cancer is the uncontrolled growth of abnormal cells in the body. Cancer develops when the body's normal control mechanism stops working. Old cells do not die and instead grow out of control, forming new, abnormal cells. These extra cells may form a mass of tissue, called a tumor.
