Which scientific design has the fewest limitations?

2 answers:

8 0

Using dissection to study the general structure of lily flowers is the scientific design that has the fewest limitations.

The dissection method includes cutting the animals body, or in this case the plant's body in order to exhibit and examine its structure. The procedure is simple and needs few tools.

If these were the choices:
A. modeling an ocean ecosystem with a saltwater aquarium
B. observing the behavior of male caribou on the arctic tundra 
C. using dissection to study the general structure of lily flowers 
D. growing algae in different environments found on a spacecraft

Then, my answer would be C. USING DISSECTION TO STUDY THE GENERAL STRUCTURE OF LILY FLOWERS.

Other choices are very hard to do. Maintaining a salt-water aquarium is very hard while going to an arctic tundra or space is impractical.

Why does ethanol becomes cloudy/white when testing fat

ki77a [65]

Answer:

Ethanol is known as a fat solvent, and the cloudy or white color that it acquires when testing fat is due to the fact that this test includes the addition of water, forming an emulsion.

Explanation:

The emulsion test for fats is a test used to show the presence of these in some substances or foods.

Under normal conditions, fats are miscible - they can be dissolved - in ethanol, an alcohol, but not in water.

This test consists of dissolving the substance to be tested in ethanol, and then adding water. The principle by which the emulsion test is governed is that ethanol allows a certain amount of fat to dissolve in water, forming a cloudy or whitish emulsion.

mixer [17]

A DNA molecule consists of two strands of nucleotides twisted together to form a double helix. The sugar-phosphate backbone is found on the outside of this helix and the bases are found braching towards the middle. Hydrogen bonds join the thenitrogenous bases and hold the two strands together.

Therefore your answer is sugar and phosphate.
