Answer:
Signposts that determine the fate of cells.
Explanation:
Embryos for humans and other animals often look alike at certain developmental stages because they share ancient genes. This expression means that a more advanced organism, like humans, will resemble less advanced species during it's development stages.
The reason both of these are valid scientific hypotheses is because A) scientists with different educational backgrounds may put forth different hypotheses to explain the same data.
This approach in science is vital in making progress and has helped to explain many phenomena in the past. When scientists explain data using different approaches, they come to a more comprehensive conclusion.
The reaction that links monomers to make polymers is polymerization. This process is also referred to as dehydration synthesis. Two monomers are binding to each other and form one polymer. Example: hydrogen (H) from one monomer binds with a hydroxyl group (OH) from the other monomer and forms the polymer : H+<span> + OH</span>-<span> = H</span>2O - the <span>water molecule. </span>
<h2>
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.
