The correct answer is - 1,180 km.
North America and Europe move away from one another, though on the other end of the plates, the Eurasian and the North American plates are actually merging. Since the rate of moving away is 2 cm per year, and the current distance is 1,184 km between North America and Europe, the distance between them 200,000 years ago was 1,180 km.
To get to the result we only need to multiply the number of years with the annual movement
2 x 200,000 = 400,000
Then divide the result with 100,000, as that is how much cm are in one km
400,000 / 100,000 = 4
And we get 4 km, in this case 4 km less, thus the distance between the two, 200,000 years ago, was 1,180 km.
Answer:
<u>C</u>. containing
- <u><em>egg albumen
</em></u>
- <u><em>protease
</em></u>
- <u><em>dilute hydrochloric acid</em></u>
Explanation:
A protease is a kind of peptidase enzyme that breaks down proteins into peptide molecules. As a digestive enzyme it is located in the lining of the stomach where, relative to the hydrochloric acid in digestive juices, the pH is usually low/ acidic.
<em>Enzymes speed up reaction rates by </em><em>providing alternative pathways</em>. By modifying the enzyme composition, supplying more collision energy, and changing the collisions between and the ratio of reactants, certain variables will increase the reaction rate.
Proteases function well at 37℃, the typical internal temperature of the human body- this temperature provides adequate energy for the reaction. Similarly, proteases require low pH for the correct configuration, and beyond this pH and temperature, they may become denatured or simply not function well as catalysts.
"
The correct answer is option B
The proper enzymes are synthesized from the information of the gene by the process of protein synthesis. All the enzymes are protein and protein are synthesized by the process of protein synthesis. These are protein in nature so they are produced in ribosomes. The gene codes for a specific protein and produces enzymes(protein).
