<h3><u>Answer;</u></h3>

b. the pH of the stroma must be higher than the pH of the thylakoid lumen

<h3><u>Explanation</u>;</h3>
  • <em><u>Energy from an electron transport chain is used to actively transport protons from the stroma to the thylakoid lumen. Thus the lumen has a relatively higher proton concentration and therefore a lower pH than the stroma.</u></em>
  • Higher [H+] means lower pH, while Lower [H+] means higher pH. During the process of photosynthesis, the lumen becomes acidic, as low as pH 4, compared to pH 8 in the stroma.

Which organisms are secondary consumers in a temperate coniferous forest?
Leya [2.2K]

Complete question:

Which organisms are secondary consumers in a temperate coniferous forest? Select all that apply:

  • moose
  • lynx
  • wolf
  • elk

Answer:

The lynx and the wolf are the only secondary consumers on the list.

Explanation:

In the trophic web, the energy transference occurs when each organism feeds on the preceding link and is eaten by the following link.

The first ones are the autotroph organism or producer, such as a vegetable, that can synthesize organic matter from inorganic matter.

The following links are the consumers: herbivores are primary consumers and feed on producers. <u>Carnivores are secondary consumers and feed on herbivores</u>, and so on. The last links are the decomposers, microorganisms that act on dead animals degrading organic matter.

According to the definition of secondary consumers, among the animals on the list, we can assume that the lynx and the wolf are the only secondary consumers. They are both carnivores and feed on herbivores.

On the other hand, the moose and the elk, are both first consumers.

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.
