Answer:

1)The three different types are Pyramids of energy, biomass, and numbers A pyramid of biomass illustrates the relative amount of living organic matter at each trophic level.

2)NO AND YES let me tell you why)) YES it would be possible the reason why i say yes its because it's on the ground and all you got to do is dig on the ground to make flat ground.NO, it would not be possible at the same time because their is a lot of animals every where and there no where to put them.

3)Pyramids of numbers. A pyramid of numbers shows the total number of individual organisms at each level in the food chain of an ecosystem. A pyramid of numbers does not always have a regular pyramid shape because it does not take into account the biomass of the organisms.No it would not be possible to construct a pyramid on the biomass unless you cut it all down!!

4)Image result for What consumes energy at each trophic level? How does this contribute to energy loss between trophic levels?

Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. Trophic level transfer efficiency (TLTE) measures the amount of energy that is transferred between trophic levels.

5) When an herbivore eats a plant, what happens to 90% of the energy obtained from that plant? 10% of the total energy from the plant gets stored in the herbivore's body as extra body tissue

6)each of several hierarchical levels in an ecosystem, comprising organisms that share the same function in the food chain and the same nutritional relationship to the primary sources of energy.The trophic level of an organism is the position it occupies in a food web. A food chain is a succession of organisms that eat other organisms and may, in turn, be eaten themselves. The trophic level of an organism is the number of steps it is from the start of the chain

7)The number of trophic level in food chain is limited because at each trophic level a large amount of energy is being utilized for the maintenance of organism and lost as heat. The energy keep on decreasing at each trophic level and only 10% of the energy is being passed to the next level

Which of the following statements correctly describes some aspect of ATP hydrolysis being used to drive the active transport of

saw5 [17]

Answer:

B) This is an example of energy coupling

Explanation:

Energy coupling is a process by which cells carry out thermodynamically unfavorable, endergonic (energy-requiring) reactions to other exergonic (reactions that liberate free energy) reactions.

Reactions which are endergonic do not occur spontaneously as they result in a decrease in entropy and a positive free energy change, ∆G.

Exergonic reactions occur spontaneously as they result in an increase in entropy and have a negative free energy change, ∆G.

For example, the active transport of ions against their concentration gradients in cells is a non-spontaneous endergonic process which is coupled to the hydrolysis of ATP, an exergonic process in other for the reaction to proceed. ATP hydrolysis phosphorylates an amino acid side chain in the transport protein which then drives the forward process of transport of the ion.

Considering the above,

Option A: The hydrolysis of ATP is endergonic, and the active transport is exergonic is false because ATP hydrolysis is exergonic while active transport is endergonic.

Option B: This is an example of energy coupling is true.

Option C: Both ATP hydrolysis and active transport are spontaneous because they result in an increase in entropy of the system is false because only ATP hydrolysis is spontaneous

Option D: Neither ATP hydrolysis nor active transport is spontaneous is false because ATP hydrolysis is spontaneous.

Option E: ATP is acting as a transport protein to facilitate the movement of the ion across the plasma membrane is false because ATP is not a protein, rather it serves to activate the transport protein by phosphorylating it.

What is the chance of an accidental discovery happening?

Anit [1.1K]

A little bit less than a purposely discovery. A discovery that you've been looking for for a while would be like 75% of discovering but accidentally would be 35% of actually discovering something accidentally.

Intrinsic factor A. increases gastric motility. B. causes the release of stomach acid. C. facilitates the absorption of vitamin

iren2701 [21]

Answer:

C. facilitates the absorption of vitamin B12.

Explanation:

The Intrinsic factor is a substance that is produced by the stomach and it has the important function of producing vitamin B12 which is necessary for life. Vitamin B12 is used in the production of mature red blood cells. It also improves the function of the nervous system. The production of this intrinsic factor is a very vital role of the stomach because, in the absence of a stomach, for example, in the case of a gastrectomy, a person can only survive if he is given injections of Vitamin B12.

The stomach also serves as a holding center for food and eventually delivers the food to the small intestine and the duodenum.
