an energy drink advertises that it contains atp. will this atp be absorbed by your muscle cells, thereby increasing the amount of atp within your muscles?

Answers

Yes, the ATP will be absorbed by your muscle cells and increase the amount of ATP within your muscles.

What is ATP?

ATP is adenine triphosphate, which is an organic compound.

The role of ATP is to provide energy to carry out many functions of the living cells.

The ATP is made up of one adenine atom attached to nine carbon atoms and one sugar group.

The ATP is the energy source and if we drink, an energy drink, the ATP will go to the body.

different photosynthetic pigments from a plant pigment extract can be separated by

Answers

The different photosynthetic plant pigments can be separated by PAPER CHROMATOGRAPHY. It is a methodology used to separate different chemical compounds based on their differential solubility.

This method (paper chromatography) uses paper sheets in order to separate mixtures of soluble substances such as, for example, plant pigments.

These paper sheets represent the 'stationary phase' through which a solution is made to pass.

Subsequently, during the mobile phase, the solvent moves through the paper sheet and thus carries (separates) different compounds with it.

Summarize the role
of organisms, including micro-
organisms, in maintaining the
equilibrium of a marine ecosys-
tem while a dead whale decays
on the ocean floor.

Answers

Answer:

The disturbance that causes the succession begins with a large whale dying and sinking to the bottom of the ocean floor. The whale carcass attracts scavengers and decomposers who eat the decaying meat.

Then, within a year, most of the whale's tissues have been eaten. The remainder of the carcass is then eaten by a much smaller number of fish. The decomposition of the whale's body will enrich the surrounding sediments with nutrients.

When only the skeleton is left, a third community moves in. Heterotrophic bacteria will begin to decompose the oils found inside whale bones. During this process, they will release chemical compounds that serve as energy sources for other bacteria. This chemosynthetic bacteria will also support a wide variety of nearby organisms living on the bones.

The decay of a dead whale on the ocean floor provides food and energy for a variety of organisms, which helps to maintain the equilibrium of the marine ecosystem.

When a whale dies, it sinks to the ocean floor and begins to decay. The decay process releases nutrients into the water, which attracts a variety of organisms, including bacteria, fungi, and worms. These organisms feed on the whale's carcass, breaking it down into smaller and smaller pieces.

As the whale decomposes, it releases carbon dioxide and other nutrients into the water. These nutrients are then used by other organisms in the ecosystem, such as algae and phytoplankton. The algae and phytoplankton use the nutrients to photosynthesize, which produces oxygen. The oxygen is then released into the water, which helps to support other life in the ecosystem.

The decay of a dead whale also provides a habitat for a variety of organisms. The whale's carcass creates a sheltered environment for small organisms, such as crabs and shrimp. These organisms provide food for larger organisms, such as fish and seabirds.

The decay of a dead whale is an important part of the marine ecosystem. It provides food and energy for a variety of organisms, which helps to maintain the equilibrium of the ecosystem. The decay process also releases nutrients into the water, which are then used by other organisms in the ecosystem.

Here are some additional details about the role of organisms in the decay of a dead whale:

Bacteria: Bacteria are the first organisms to colonize a dead whale. They break down the whale's carcass into smaller and smaller pieces.Fungi: Fungi also play a role in the decay of a dead whale. They break down the whale's carcass into even smaller pieces, releasing nutrients into the water.Worms: Worms are another important group of organisms that help to decompose a dead whale. They burrow into the whale's carcass, breaking it down into even smaller pieces.Algae: Algae and phytoplankton use the nutrients released by the decay of a dead whale to photosynthesize. This produces oxygen, which helps to support other life in the ecosystem.Fish: Fish are attracted to the carcass of a dead whale. They feed on the whale's flesh and bones, as well as on the smaller organisms that live on the carcass.Seabirds: Seabirds also feed on the carcass of a dead whale. They eat the whale's flesh and bones, as well as the smaller organisms that live on the carcass.

The decay of a dead whale is a complex process that involves a variety of organisms. These organisms play an important role in maintaining the equilibrium of the marine ecosystem.
