5 0

Sharks belong to a family of fish that have skeletons made of cartilage, a tissue more flexible and lighter than bone. ... The upper side of a shark is generally dark to blend in with the water from above and their undersides are white or lighter colored to blend in with the lighter surface of the sea from below.

The figure shown above shows the energy levels for a hydrogen atom. What is the energy of the photon emitted when the electron i

tankabanditka [31]

The <span>energy of the photon emitted when the electron in a hydrogen atom drops from energy level E5 to energy level E2 is 2.85eV

Now, the energy of the ground state is -13.6 eV.
</span>the energy of the first state (n = 1) is -3.39 eV.
the energy of the fifth state is -0.54 eV.

Now, When an electron drops from higher to lower state, then energy difference is same as the energy of the photon emitted, is
= E5 - E2
= -0.54 eV -(-3.39 eV)
= 2.85 eV

Which of the following is most likely true of a protein that cotransports glucose and sodium ions into the intestinal cells of a

Step2247 [10]

Answer:

D) Transport of sodium ions down their electrochemical gradient facilitates the transport of glucose against its concentration gradient.

Explanation:

Active transport refers to the movement of molecules across biological membranes against a concentration gradient. Active transport can be divided into 1-primary active transport, which requires energy from the hydrolysis of adenosine triphosphate (ATP); and 2-secondary active transport, which requires an electrochemical gradient generated by pumping ions in/out of the cell. The case above described represent a type of secondary transport active because the movement of sodium (Na) ions is used as energy source to move glucose molecules against their concentration gradient.
