Answer:

B. introns; exons

Explanation:

Related genes from different organism usually translate to proteins of indispensable functions. This means that the proteins must be similar in terms of amino acids produced. Therefore the coding region must be highly conserved. These can be found in the introns. Conversely, exons are not a part of the coding sequence and therefore not required for translation. These sequences may be less conserved.

Please help!! Can you figure out the modern spreading rate of the Mid- Atlantic ridge? Use that line to figure out how many kilo
bija089 [108]

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
