All of the given answer options represent organisms that could coexist in an ocean
ecosystem. In this hypothetical ecosystem, which organism will receive the least amount of
energy in the food pyramid?
Tuna
Great white shark
Seal
Anchovy

Answers

Answer:

B. Great white shark

Explanation:

In any food pyramid, the organism at the top of the food pyramid usually gets the least amount of energy in the food pyramid, while those at the bottom have the highest energy in the food pyramid. This is because, as energy moves up the pyramid, some are lost.

In an hypothetical ecosystem, the great white shark will top the food pyramid. Therefore, it would get the least amount of energy in the food pyramid.

Answers

Answer:

The study of microbes in their natural habitat and their relationship with each other and their environment is termed as Microbial ecology. It mainly constitutes of Viruses, Eukaryotes ,Bacteria and Archaea as its living entities.

Being omnipresent in the biosphere they impact the other life-forms up to a significant extent.

They also help maintaining biogeochemical cycle by nitrogen fixation, sulfur metabolism and methane metabolism. Microbes also play a vital role of availing energy in the ecosystems where sunlight is scarce and hence photosynthesis is not good means of energy trapping, in such ecosystems the microbes actively engage in fundamental ecological processes including production, decomposition, and fixation inside the host organism.

Answers

There are two broad classes of seismic waves: body waves and surface waves. Body waves travel within the body of Earth. They include P, or primary, waves and S, or secondary, waves. P waves cause the ground to compress and expand, that is, to move back and forth, in the direction of travel.

After ATP donates a phosphate group to a coupled reaction, then it becomes ADP. The ADP Group of answer choices can be recharged in an equilibrium reaction to form ATP. can be recharged in an oxidation reaction to form ATP. can be recharged with the release of energy to form ATP. is a waste product that will be broken down. can be recharged with the uptake of energy to form ATP.

Answers

Answer:

can be recharged with the uptake of energy to form ATP

Explanation:

The correct answer would be that the ADP can be recharged with the uptake of energy to form ATP.

ADP is converted to ATP within a cell when free energy is available. The free energy is stored by coupling a phosphate group to ADP to form ATP, such that:

ADP + P (inorganic) + Free Energy ------> ATP

Hence, ADP can only be recharged with the uptake of energy to form ATP, a kind of reaction generally referred to as endergonic reaction.

In the electron transport chain, which structure forms a channel in the inner membrane of the mitochondria and adds phosphate to ADP

Answers

Answer: ATP synthase

Explanation:

The ATP synthase complex is an enzyme located in the inner membrane of the mitochondrion that catalyzes the synthesis of ATP from ADP, a phosphate group and energy supplied by a proton (H+) flux. This ATP synthesis occurs during cellular respiration, which is a set of biochemical reactions by which certain organic compounds are completely degraded by oxidation to inorganic substances. This process provides usable energy to the cell in the form of ATP.

During cellular respiration, ATP synthesis is termed oxidative phosphorylation and the proton flux takes place between the intermembrane space and the mitochondrial matrix. ATP synthase produces ATP when protons flow through it. The proton flow creates a pH gradient and an electrochemical gradient. This proton gradient is used by ATP synthase to form ATP via oxidative phosphorylation. ATP synthase acts as an ion channel that "returns" protons to the mitochondrial matrix. During this return, the Gibbs free energy produced during the generation of the oxidized forms of electron transporters is released. This energy is utilized for ATP synthesis. It must then be considered that the electron transport chain and oxidative phosphorylation are coupled by the proton gradient.

A diagram shows a potato producing new tubers. Buds on the parent plant grow into stems that grow downwards called stolons. The end of each stolon develop in to new tuber.

1) Give two pieces of evidence which show that this is an asexual method of reproduction.

2) Explain why all the new tubers will be genetically identical.

Answers

Answer:

See the answer below

Explanation:

Evidence that shows that the illustration is an asexual method of reproduction:

1. New tubers were produced without any signs of flowering or fertilization

2. Parent plant was produced from a vegetative part ( a tuber).

All the new tubers would be genetically identical because they were produced without fertilization. They all developed from the division of some of the vegetative cells (mitosis) of the parent plant. Hence, they are not only genetically identical with themselves but also with the  old tuber that produced the parent plant.

Some protozoans have special organelles called contractile vacuoles that continually eliminate excess water from the cell. The presence of these organelles tells you that the environment Group of answer choices is hypotonic to the protozoan. contains a higher concentration of solutes than the protozoan. is isotonic to the protozoan. is hypertonic to the protozoan.

Answers

Answer:

is hypertonic to the protozoan.

Explanation:

The presence of contractile vacuoles tells us that the environment  is hypertonic to the protozoan that contains a higher concentration of solutes in the outside environment than the protozoan. The water moves outside the cell if its concentration is higher inside the cell so due to diffusion and no need of extra water, the water removes by the contractile vacuole to the outside environment so we can say that the environment is is hypertonic to the protozoan.
