Chondroblasts ________. Chondroblasts ________. are mature cartilage cells located in spaces called lacunae never lose their abi
Mariulka [41]

Answer:

within the cartilage divide and secrete new matrix

Explanation:

Chondroblasts also called as perichondrial cells form chondrocytes which are the cells of cartilage. They also secrete the cartilage matrix which forms the cartilage. This matrix consists of collagen, fibers, proteoglycans, hyaluronic acid, water and glycoproteins.

They divide within the formed cartilage too to secrete new matrix. They are called chondrocytes when they become a part of cartilage matrix. Here they grow the cartilage matrix by secreting more extracellular matrix rather than dividing. Once the cartilage formation is completed it is composed 10-20% of collagen fibers, 65-80% of water and rest is made by proteoglycan-hyaluronic acid aggregates.

Which substance is completely consumed in a chemical reaction?
Rudiy27

Answer:

Limiting Reactant

Explanation:

Observe the answer choices:

A) Limiting Reactant; a limiting reactant, as can be seen from the name, is the reactant that <em>limits</em> the amount of products can be made. This is because the reaction can only go on if there is enough reactants. However, the limiting reactant is the one that will run out first, so it's going to be completely consumed.

B) Reactant; a reactant is the thing that is being consumed in a reaction. However, reactants aren't always completely consumed. There's something called an excess reactant, which is essentially the opposite of a limiting reactant in that when the limiting reactant is used up, there's still some excess reactant left - because it's in <em>excess</em> / there's more than enough remaining. So, this is incorrect.

C) Products are the ones that are created during the chemical reaction, so they aren't consumed in any way. Thus, this is wrong.

The answer is limiting reactant.

Hope this helps!

aleksklad [387]

You would revise the simulation so users can evaluate the role of human activity in the pH of the ocean by lowering the temperature.

<h3>What is pH?</h3>

pH may be defined as the power of hydrogen. It determines the acidity or basicity (alkalinity) of any substances under any temperature or pressure.

The role of human activity affects the overall consequences of oceans to a larger extent.

Therefore, you would revise the simulation so users can evaluate the role of human activity in the pH of the ocean by lowering the temperature.
