Answer:
At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed.
Explanation:
Oxygen, liquid water, and life is on planet earth
" As we follow along on a cladogram, it will split at nodes into two or more internodes a specitation event (the formation of new species). The line between two specification events, the internode, represents at least one hypothetical ancestor."
The answer is c because curies release energy from the radiation

Answer:</h2>
Glucokinase or Hexokinase is a enzyme used at the first step of glycolysis.
<h2>
Explanation:</h2>
- Glucokinase is a Isoenzyme(enzymes which differs in the sequence of amino acids but catalyses the same reaction) of Hexokinase .
- Glucokinase (hexokinase D) is present only in liver and pancreas whereas hexokinase is present in all cells.
- In first step of glycolysis i.e formation of glucose-6-phosphate from glucose is completed with the help of hexokinase. In this step a ATP molecule is consumed i.e ATP is converted to ADP
Result: Glucokinase and hexokinase are used in the first step of glycolysis.
