Answer:
According to the result recorded, there was no cholesterol in the albumin solution. This is probably because the cholesterol is in the egg yolk and not the egg white. In order to get a positive response on the presence of cholesterol in eggs, an egg yolk albumin stock needs to be prepared. So using the same procedure as before and only replacing the egg yolk for the egg white, prepare a 0.5 mL of egg yolk with 4.5 mL distilled water mixture in a test tube. Follow the steps given in the lab manual to check for presence of lipids in this albumin stock. Take a filter paper and add one drop of Sudan III solution onto it, let it dry and then place a drop of the stock prepared and analyze if the color transfer happens.
Hope that answers the question, have a great day!
Answer:
The photosynthetic rate refers to a determination of maximum rate at which leaves possess the tendency to fix carbon at the time of photosynthesis. The simple way by which the photosynthetic rate can be determined is by measuring the concentration of carbon dioxide produced.
It is known that the concentration of carbon dioxide, light intensity, and temperature are the three main elements, which affect photosynthesis. The enhanced concentration of carbon dioxide and higher light intensity results in higher photosynthetic rates.
In the given case where Elodea is used to study photosynthesis, it can be seen that at high light intensities, the concentration of bubbles increases as there is an elevation in the concentration of carbon dioxide.
Answer: Option B.
Precise but inaccurate.
Explanation:
It is precise because the measurement taken with well incremated tool reflect how close it is to the actual value i.e it has the quality of been exact but diet to the missing of 4.0 centimeter because a hungry beaver made a snack of it earlier that day the measurements will be INACCURATE because it does not conform with the result of the standard or correct value to be gotten.
Most of the marine animals have a stream lined body, which means, they have a sharp and pointed at the front. The pointed front of the organism allow to cut the resistance of the water. In case, the body is not pointed at the front and it is blunt, the water current and flow would resist the movement of the organism further. So, for the locomotion purpose, it is important to have a streamlined body. Further smooth and hair less body also decrease the resistance during the movement in the water.
