Please help!! I WILL GIVE BRAINLIEST !! Can you figure out the modern spreading rate of the Mid- Atlantic ridge? Use that line t
Naddik [55]

Answer:

R = 16mm/y  

Explanation:

Modern Spreading Rate (R) = distance the seafloor moved in km (d) / age in million years (t)

R = d/t

To calculate it in millimeters per year we need to convert it:

<em>1 km = 1000 m </em>

<em>1 m = 100 cm </em>

<em>1cm = 10mm</em>

<em>1 km = 1,000,000 mm   </em>

The problem states that in 150 million years, there is a distance of 2400 km.

if 1 km ------- 1,000,000 mm

2400 km-------X = 2400,000,000 mm

If 1 million years -------1,000,000 years

150 my----X = 150,000,000 years

R = d/t

R = 2400,000,000 mm/150,000,000 y.

R = 16mm/y

What happens in photosystem II?
netineya [11]
<h2>Answer:</h2>

The correct answer is option A which is, "Electrons are re-energized to be used in NADPH production".

<h3>Explanation:</h3>

In photosystem II, light energy is used to split water molecules which release electrons.

These electrons then move to photosystem I to reduce NADP to NADPH.

Hence electrons in photosystem II are ultimately used to produce NADPH and option C is the correct statement.
