Which statement is an example of the chemical potential energy in adenosine triphosphate (ATP) being turned into work?
evablogger [386]

Answer:

The correct answer is option (C) "After splitting ATP, a protein changes shape to pump ions across a membrane".

Explanation:

Adenosine triphosphate (ATP) is an organic chemical molecule considered the "molecular unit of currency" of intracellular energy transfer, for the high level of energy that is released when ATP is breakdown into adenosine diphosphate (ADP). ATP provides energy to drive many processes in living cells. One example of how the chemical potential energy of this molecule is turned into work is that after splitting ATP, a protein changes shape to pump ions across a membrane. The energy of the splitting of ATP into ADP will provide energy for the protein being able to change shape, resulting in pumping ions across a membrane.

Describe the strength of the magnetic field at points a b and c in the image below. Explain your answers in the terms of magneti
Nastasia [14]

The magnetic fields are strongest at point A and weakest at point C. The magnetic field lines can be used to indicate the strength of a magnet or magnetic field. The closer together the magnetic field lines the stronger the magnetic field.

Explanation:

The magnetic field line also shows the direction of the magnetic field, hence they are also considered vector fields because they have magnitude and direction. They usually have an arrow indicating that the field lines are moving from the north pole to the south pole. The lines also never cross and are always in closed loops.

Organisms that have a physical trait that makes it easier for them to access food supplies are unlikely to pass on that trait to
JulsSmile [24]

The right answer is false.

All the physical characteristics of an individual, which are at the basis of genetic characters (sometimes even epigenetic), are transmitted to his offspring.

Classical or monogenic Mendelian inheritance is based on the transmission of a single gene in a dominant, recessive mode, linked to the sex chromosome X (or Y), or more rarely mitochondrial (extranuclear) chromosome.
