Answer:
This is usually the first day of menstruation - the day when the uterus lining starts to be shed.
Explanation:
The Benedict’s Test is the test which can detect carbohydrates and glucose in foods. During this process, the sample or the food is placed into a test tube and then some drops of Benedict's solution is added to it,and is then put into a beaker of boiling water. When the mixture of food and the Benedict substance turns reddish orange instead of staying blue, this means that it is positive. The mixture has simple sugar or has carbohydrates or glucose. On the other hand, lipids are tested using the brown paper test. When the paper turns transparent when a drop of food is put into it, it means that is is positive as well. When you want to test if the food has proteins, you have to test it with Biurets. Observe if the color change when you put some Biurets solution to the food sample. It is positive if the food turns light purple. Test if the food is positive with starches through the use of iodine. Food having iodine drops should turn purple instead of staying a yellow color.
Answer: It is because it makes it more efficient to study organisms.
Explanation: Biologist classify organisms by considering similarities between them. The organisms which have closely related characteristics are placed in a separate domains by biologists. Domains are further divided into 6 Kingdoms. According to modern classification system, domain is largest unit of biological classification.
Answer:
The main function of the circulatory (or cardiovascular) system is to deliver oxygen to the body tissues, whilst simultaneously removing carbon dioxide produced by metabolism.
Answer:
What would be the expected result of the experiment?
For the drawing of the map part, the scientific will find that effectively, a very large number of volcanoes are located near the meeting points of tectonic plates. The volcanoes that aren't now at the edge of the plate were most probably at the moment of their formation, and were moved away by the movement of the plate.
But I doubt the scientist would be able to identify many new volcanoes, because the creation of a volcano isn't something happening overnight.
How would you interpret the results if the scientist observes no new volcanic activity?
I would say that does NOT invalidate the theory because the observation period is extremely short. 10 years is an insignificant amount of time geologically speaking... the study would have to be conducted over at least 1,000 years to maybe have some results at all. Just imagine how many volcanoes there would be if a new one was created every 10 years along the side of a tectonic plate.
