Answer:

Any process that involves active transport most often involves the​ expenditure of energy in the form of ATP hydrolysis.

Explanation:

Active transport in cells is a form of transport which involves the transport of solute molecules across a membrane against a concentration gradient using energy provided from some chemical reaction occuring in the cell.

Active transport is an endergonic (energy-requiring) process and therefore, must proceed only when coupled to an exergonic (energy-releasing) process such as the breakdown of ATP, an oxidation reaction, absorption of sunlight, etc.

In many instances in cell, such as the Na/K pump, ATP hydrolysis is the the common exergonic reaction to which active transport is coupled to.

What protein (purine)-rich food should be limited to prevent a reoccurrence of uric acid kidney stones? what protein (purine)-ri
Nataliya [291]

Answer:

Eggs

Explanation:

Uric acid stones are one of the four types of kidney stones which are formed due to the high amount of uric acid in the human body.

When the concentration of the uric acid increases in the urine due to which urine becomes acidic, the uric acid gets stored in the urinary pathway in the form of stones.

To remove the uric acid kidney-stones, the food rich in purines must be avoided like meat, eggs and green vegetables like mustard, spinach, and whole grains are suggested.

Thus, the egg is the correct answer.

How do scientists explain the slow rotation of the sun with respect to the rest of the solar system?
nataly862011 [7]

Answer:

The Sun rotates on its axis once in about 27 days. This rotation was first detected by observing the motion of sunspots. The Sun's rotation axis is tilted by about 7.25 degrees from the axis of the Earth's orbit so we see more of the Sun's north pole in September of each year and more of its south pole in March.

Since the Sun is a ball of gas/plasma, it does not have to rotate rigidly like the solid planets and moons do. In fact, the Sun's equatorial regions rotate faster (taking only about 24 days) than the polar regions (which rotate once in more than 30 days). The source of this "differential rotation" is an area of current research in solar astronomy.
