Light travels in a straight line as a wave. It does not require any medium or material to travel like sound waves which means it can travel in vacuum.The speed of the light  from the special theory of relativity is a constant value of  34\times 10^{8} m/second.

Hence, the correct answer is option (D).

Bacteriorhodopsin pumps protons across the bacterial plasma membrane from the cytosolic side to the extracellular side of the me
julsineya [31]

Answer: Option B.

B. The chromaphore retinal absorbs a photon of light, causing a double bond in retinal to isomerize from trans to cis configuration.

Explanation:

Bacteriorhodopsin is a protein used by archaea or half bacteria that pumps proton across membrane by using the light energy from sun to move protons across membrane. It is found in purple membrane of archaea cells which is known as two dimensional crystalline patches.

It captures photon energy through chromophore retina which is covalently bound and transporting the photons against their electrochemical gradients from the cytoplasm to the extracellular space.

Construct an explanation to predict the type of symbiotic relationship that exists between the hippo and oxpecker birds?
Allisa [31]
<h2>Answer:</h2>

However, the bird gets food by making little cuts in the hippopotamus to obtain insects. This isn't entirely harmful to the hippopotamus though.</u></em></h2>
