Solid because it maintains their shape and is rigid 
in this case the answer would be letter "D"

Answer:

Solid

Explanation:

Solid phase of matter is characterized by presence of less or no space between its particles. The atoms of the molecules are placed close to each other and are bonded together. Absence of gaps and tight bonding does not allow the particles of the substance to move part each other and results in rigidity and fixed shape.

Diffusion is an important process in animals and plants.
Paraphin [41]

Answer:

Diffusion helps animals in respiration. The cells in an animal's body need glucose and oxygen for respiration. Both these are carried in the blood. When blood reaches the cells the molecules of glucose and oxygen diffuse out of the blood and into the cells. As cells use up the glucose and oxygen they produce waste chemicals and carbon dioxide.

Diffusion is a very important process for photosynthesis where carbon dioxide from the stomata diffuses into the leaves and finally into the cells. This helps the plants to photosynthesize and produce more food.

Example for animals: Animals using glucose and oxygen in diffusion.

Examples for plants: Plants using carbon dioxide to photosynthesize.

How do I Construct a table to compare the products and reactants in photosynthesis and cellular respiration
katen-ka-za [31]

Explanation:

Create the column headings "Reactants" and "Products". The two row headings should be "Photosynthesis" and "Cellular respiration".

Before filling in the table, make sure you know what the products and reactants from photosynthesis and cellular respiration are.

Remember reactants are the 'before' on the left, and products are the 'after' on the right.

<u>Photosynthesis</u>:

CO_{2} + H_{2}O+light =>O_{2}+C_{6}H_{12}O_{6}

<u>Cellular Respiration</u>:

O_{2}+C_{6}H_{12}O_{6}=>CO_{2} + H_{2}O+ATP

See attachment for how the table could look.

A researcher is designing a laboratory experiment to determine whether the inorganic substance A affects the rate of a reaction
Bas_tet [7]
First, he should measure how long it takes for the liquid to become clear if X and Y are mixed together. Then, he should measure how long it takes if he also adds substance A to X and Y. He will find out if substance A is a catalyst. hope this helps :)
