The correct answer is option B. shown that the tidal forces needed to move continents would stop Earth’s rotation.

The Wegener’s idea that tidal forces might cause continental drift suggested that the tidal force and the centrifugal forces on the earth was the cause of the movement of the plates.

But, he was unable to propose the mechanism of such movement. Also, if the centrifugal force of the earth would move the plates apart, then the earth below it should remain stationary, but the earth is in continuous rotation, so, this idea was not acceptable, as it is would stop rotation of earth.

Which of the following is true of rods?

Alex17521 [72]

Answer: A - Rods are more numerous than cones

Explanation: Rods are found everywhere in the retina except the fovea (a tiny pocket in the retina where just about all of the cones are located).

B. The macula lutea is another word for fovea, no rods are found there.

C. Rods are utilized in low-light conditions and are not sensitive to wavelengths of light.

D. Cones are responsible for perceiving color and not rods.

E. The main function of the rods is to help us see in low-light conditions (scotopic vision), so this answer would be incorrect.

A scientist is using a species of green algae to study the electron transport chain in photosynthesis. He uses a laser to inacti

jeka94

Answer:

D) In case 1, both PS I and PS II completely lose function; in case 2, a proton gradient is still produced.

Explanation:

The light dependent reaction of photosynthesis, which produces the ATP and NADPH needed in the light independent stage of the process, includes complexes of proteins and pigments called PHOTOSYSTEMS. These photosystems (I and II) are key to the functionality of the light dependent reactions in the thylakoid.

The major pigment present in both photosystems is CHLOROPHYLL A, which absorbs light energy and transfers electrons to the reaction center. Chlorophyll B is only an accessory pigment meaning it can be done without. Hence, if all of the chlorophyll A is inactivated in the algae but leaves chlorophyll B intact as in case 1, both PS I and PS II will lose their function because Chlorophyll A is the major pigment that absorbs light energy in both photosystems.

In case 2, if PS I is inhibited and PS II is unaffected, a PROTON GRADIENT WILL STILL BE PRODUCED because the splitting of water into protons (H+) and electrons (e-) occurs in PSII. Hence, H+ ions can still be pumped into the inner membrane of the thylakoid in order to build a proton gradient even without the occurrence of PS I.

In the human respiratory system, gas exchange occurs across the cells of the ________.

pashok25 [27]

In the human respiratory system, gas exchange occurs across the cells of the alveoli. Alveoli or an alveolus is the deepest part of the human respiratory system. This part of the respiratory system is a place where gas exchange between oxygen and carbon dioxide occurs from inhaled air to the blood cells.
