Answer: D. Digestion increases as the volume of the enzyme increases.

Explanation:

Enzymes speed up reactions by reducing the activation time of a reaction. If there are more enzymes therefore, the reaction will move faster.

Pepsin is an enzyme that prefers acidic conditions so it can work with dilute HCL. It can also work in temperatures of 40 °C without getting denatured. As more Pepsin is added therefore, the reaction will move faster and digestion will increase.

Answer: The only reaction performed by chloroplast through its chlorophyll is photosyntesis. Therefore the chemical formular is below.

   C02         +          H20           →                   C6H1206    +       O2+           H20.

(carbondioxide) +    (Water)     Chlorophyll      (glucose)  +(oxygen)+     (water)

                                                       and                                                                                            

                                                   enzymes .                    

This is the single reaction of the process of photosynthesis.However two interconnected reactions are involved light dependent stage and light independent stage.

The first reaction takes place in presence of sunlight, and it is called Photolysis of water.it is the spiting of water to H+, electrons and Oxygen. This is  the source of oxygen seen above.

             4 H20→ 4H+ + 4e- + 02.

The light independent stage; the hydrogen ion from the photolysis is transfer to the light independent stage to reduce the C02 to produce glucose.In the first equation seen above.

Since chloroplast performs photosynthesis through action of its chlorophyll, The above reaction describes the chemical formula.

B.

The cell wall  of plants is made up of the middle lamella, the primary cell wall and the secondary cell wall .

<u>Cellulose</u><u> a complex carbohydrate is the major components</u>. It contains,  monomers of  glucose in small units  linked to one another by bonds.

C

Vacuole helps in plant turgidity needed for uprightness. when filled with water provides  turgor pressure increases as the cell membrane pushes against the cell wall. The resulted turgidity  helps the plants  to maintain resistance to external pressure and therefore resist the effects of gravity.

Is there a scientific reason why adults don't really understand their children?
Alenkinab [10]
Throughout their teenage years, children's minds are literally being rewired. Teenagers are unable to comprehend facial expressions or other's emotions which can make it for others to understand them or for them to even understand themselves.

Materials are able to move across a cell membrane through one of two methods: active transport or passive transport. What is the
zloy xaker [14]
Essentially the answer is in the names. Active transport requires energy to facilitate to movement of the materials while passive transport is something like osmosis which is when the material moves based on concentration in an effort to create equality between the two sides. Basically passive is when the materials move under the own power.
