Answer:
To know and compare the difference between the density of the fresh water and salt water or sea water require a graduated cylinder, balance, and weighing machine. The graduated cylinders are the containers that have markings on them to measure the volume of the liquid.
First, fill the cylinder with 1000 ml of fresh water which is the measure of the volume. now weight the cylinder filled with the fresh water and then find the difference between filled and empty container divide the mass of the fresh water by its volume, the result is the density of fresh water.
Repeat the process with salt water or sea water. The answer would be sea water has more density than fresh water.
The answer is - hypothesis.
In here we have a situation where the scientist has be observing a certain behavior of the snakes under certain conditions. So he has some basis for proposing it as new exciting discovery, but the evidence are still basic ones and further investigation is needed.
Considering the definition for what is a hypothesis - ''a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation'' - it perfectly fits the given scenario.
A-
1. Like water, other types of matter like carbon, oxygen , and nitrogen go through physical and chemical changes.
2. The total mass of the matter is the same before and after a change this is known as the laws of conservation of mass.
3. Most of Earths water is in the ocean.
4. The path water follows as it moves from Earth through the atmosphere and back to Earth is called the water cycle.
5. The three processes involved in the water cycle are evaporation, condensation, and precipitation.
a. Water changes from a liquid to as gas during the process of vaporization.
b. water vapor changes back into liquid water during condensation.
c. . Rain, snow, sleet, and hail are examples of precipitation.
Honestly that's all the answer I can put up with right now but I hope I have come to do you good and helped you through :)
The answer to that is sunlight. If you need an explanation tell me but I think it’s self explanatory :)
Answer:
To suspend organelles and other subcellular parts.
Explanation:
Controlling what enters and exits the cell is done by the plasma (cell) membrane. Ribosomes synthesize proteins. Nuclei/Nucleoids store genetic information in eukaryotes.
