Most of the active volcanoes on earth are located in a belt known as the ring of fire.

The ring of fire is a large 40,000 km horseshoe shaped region situated in the basin of the Pacific Ocean. The ring of fire is characterized by constant sequence of plate movements, volcanic arcs and belts, and oceanic trenches. About 90% of all earthquakes and about 75% of all active volcanoes on earth occurs in the ring of fire.

klemol [59]

Answer:

A. Yes, because an amino acid change has occurred.

Explanation:

The sequence given states that the codon CCG is changed to CAG. According to the codon table (attached), CCG codes for <u>proline</u> whereas CAG codes for <u>Glutamine</u>. Therefore, change in mutation has resulted into the change in amino acid. This would lead to the formation of a different protein.

Lelechka [254]

Answer:

<h2>c. Division of these two groups occurred after the protostome developmental sequence appeared. </h2>

Explanation:

Protosomes are such types of organisms in which the mouth part developed first during embryonic development.
Those animals in which anus develop first are known as deuterostomes.
This differentiation takes place during the embryonic development of the organisms.
Since lophotrochozoan and Ecdysozoa both are protostomes animals and categorized on the basis of molecular evidence.
Thus these two groups were formed after the appearance of the protostomes.

A cross country runner runs 8 km in 2 minutes. What is his speed?

oee [108]

The speed of the cross country runner is equal to 4 km/min.

<u>Given the following data:</u>

Distance = 8 km.

Time = 2 minutes.

To determine the speed of the cross country runner:

Speed can be defined as the distance covered by an individual per unit time and it can be measured in kilometer per minutes (km/min).

Mathematically, speed is given by the formula;

$Speed = \frac{distance}{time}$

Substituting the given parameters into the formula, we have;

$Speed = \frac{8}{2}$

Speed = 4 km/min.
