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.

A particular leg bone for dinosaur fossils has a mean length of 60 inches with a standard deviation of 3 inches. What is the len
stepan [7]

The average length of a specific dinosaur leg bone is 60 inches, with a standard variation of 3 inches. If a z-score is 0, then the length is 67.

Divide your data point by your standard error after taking your data point and subtracting the mean from it. How is the z-score determined? Z-scores are calculated using the formula z = (x-)/, where x represents the raw score, the population mean, & the population variation. The z-score is just the raw score less the population mean, split by the population variance, as the calculation demonstrates. You now have your Z-score. For instance, a scoring of 450 would equate a scores of (450-500)/100 (= -50/100 = -0.50 on a scale with a mean of 500 as well as a standard variation of 100, indicating that the scoring is half a variance below the mean.
