Sunlight is the source of energy for the process to take place. Solar energy from the sun is converted into chemical energy for the process of photosynthesis. Hope that helped. Have a nice day
You have to remember that a scientific hypothesis is a question about whether or not something will happen the way you think it will.
Answer: These methods works by denaturing the enzymes. The first and the second method is to change the temperature and the third method is to change the pH.
Explanation:
The browning of the fruits or vegetables takes place due to the action of the enzymes. The enzymes inside the body of the organism works under specific conditions.
These conditions are temperature and pH. Change the optimum pH and temperature of the environment of enzymes could denature it.
In these case the enzymes would not work efficiently and the browning of fruits will not take place.
By cooling or boiling the fruit changes the temperature of the enzyme and in this temperature the enzymes do not work effectively.
In case of ascorbic acid the pH is acidic and enzymes do not work at lower pH.
So, by changing the pH and temperature, the enzymes do not work.
Answer:
<h2>A</h2>
Explanation:
1. Sickle cell anemia is an inherited condition, disorder (disease).
2. It is a recessive condition, in which red blood cell become mutated and converted to a sickle like shape, and there aren't enough healthy red blood cells to carry oxygen throughout the body.
3. This condition normally occur when, there is inheritance of two abnormal or mutated copies of the β-globin gene, one allele from each parent.
4. β-globin gene makes haemoglobin.
5. Sickle cell anemia results when glutamic acid being substituted by valine at position 6 ( in short E6V substitution).
6. So, it a single base-pair substitution in the gene encoding the beta subunit.
They move faster and therefore have more energy.
