It is believed that the ratio of cyclic electron transport to Z-scheme photosynthesis changes in response to metabolic demands. If a plant were actively engaged in a large amount of reductive biosynthesis, requiring NADPH, how would it alter these processes compared to a plant just performing the Calvin cycle to produce glucose

Answers

Answer:

The correct answer is (b) More Z-scheme photosynthesis, less cyclic photophosphorylation

Explanation:

Z-scheme is the schematic flow of the electrons from water to NADP+ and as it connects the two different photosystems that look like z in the diagram it is termed as Z-scheme of photosynthesis. The ratio of cyclic electron transport to Z-scheme photosynthesis alters as per the metabolic requirements. In the question, it is given that If a plant were actively engaged in a large amount of reductive biosynthesis, requiring NADPH, then it will acqiuire more z-scheme photosynthesis compared to a plant just performing the Calvin cycle to produce glucose.

Answer:  More Z-scheme photosynthesis, less cyclic photophosphorylation

Why are NADH and FADH2 necessities in the electron transport chain?(1 point)

They move down the electron transport chain.
They move down the electron transport chain.

They move electrons to the electron transport chain.

Answers

NADH and FADH2 are necessities in the electron transport chain because they power the chain by moving electrons into it.

NADH and FADH2 are both generated at the initial stages of respiration (the Kreb's cycle), a process during which food materials are broken down to generate energy. NADH is generated from NAD+ as a result of the addition of electrons while FADH2 is generated from FAD also due to the addition of electrons.

Once generated, both compounds get transferred into the innermost membrane of the mitochondrion where they travel down the electron transport chain, donating their electrons in the process and creating an electrochemical gradient to generate ATP.

Without NADH and FADH2, there will not be electrons to power the electron transport chain and the generation of ATP would become impossible.

The graph shows the supply and consumption of forests when the
consumption rate and population growth rate are both low.
When does consumption begin to surpass supply?

Answers

Answer:

In about 625years

Explanation:

According to the graphical representation depicted in this question, it shows the supply and consumption of forests when the consumption rate and population growth rate are both low. The green line represents the total consumption while the red line represents the total supply.

Based on observation of the graph, the total consumption exceeds or surpasses the total supply at a little above 600 years. Approximately, this can be said to be in about 625years.

Answer:

In about 625 years

Explanation:

Consumption has definitely surpassed supply by 700 years, but it only begins to surpass it around the 625 year mark according to the graph

What is a likely consequence of continued human population growth? A. More rain forests B. Fewer urban centers Ο Ο Ο Ο O C. Less pollution D. Depleted natural resources​

Answers

Answer:

D. Depleted natural resources​

Explanation:

If the human population on Earth continues to grow, depletion of natural resources is a very likely consequence.

Especially at the rapid rate that humans consume natural resources, continued population growth would eventually deplete them.

Fossil fuels are an example of natural resources that will eventually deplete, as humans use immense amounts of things like coal and natural gas.

Answer choices A, B, and C are incorrect because they would be consequences of decreased human population growth.

So, the correct answer is D. Depleted natural resources.

C. The plants must be older than the Brachiopods.
D. The Brachiopods must be older than the plante

Answers

Answer:

C

Explanation:

because the plants are farther down lol

Paleontology establishes the geological age of the organisms. Based on the height of the fossils discovered at the Grand Canyon, it can be concluded that plants were older than the Brachiopods. Thus, option C is correct.

What are fossils?

The dead remains and decaying materials of the plants and animals stored and preserved under the sediments and rock layers over a period of many years are said to be called fossils.

The fossils are evidence of the evolution as well are used to determine the geological age of the species based on their occurrence of them in the rock layers.

The fossils of plants like horsetails and ferns were found 300 ft above the Canyon while Brachiopods at 10 feet above Canyons that tell that plants were found earlier than the former species.

Therefore, option C. the plants existed prior to the Brachiopods.
