Please help Can you figure out the modern spreading rate of the Mid- Atlantic ridge? Use that line to figure out how many kilometers a plate moved from the spreading boundary in a set number of years. Convert that rate to the distance a point moves in just one year, rounding your answer to the nearest millimeter.

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:

1 km = 1000 m

1 m = 100 cm

1cm = 10mm

1 km = 1,000,000 mm  

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

if 1 km 1,000,000 mm

2400 kmX = 2400,000,000 mm

If 1 million years 1,000,000 years

150 myX = 150,000,000 years

R = d/t

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

R = 16mm/y  

a neutral ph of 7 and normal organism temperature is needed for a certain enzyme to be effective.  

what would happen to the enzyme if the ph and/or temperature fluctuate greatly from the norm?  

a.the enzyme’s hydrogen bonds will break.  

b.the activation energy will increase.  

c.more product will be formed.

d.the ideal temperature and ph for the enzyme function will decrease.
