Sea Lampreys, a jawless fish that feeds on other aquatic

Biology
1 answer:
aliya0001 [1]2 years ago
3 0

Your answer would be Why are Sea Lampreys a problem in the Great Lakes?

In the text, it explains the answer for this question. For the other three questions, it's asking for a factor of the paragraph rather than the whole thing. The whole paragraph explains the answers for all of the questions, so it's best to ask why are they causing problems.

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.
