Amoebas are unicellular. The single cell splits in half to form two new cells. A student claims amoebas are alive. Is the studen
Norma-Jean [14]

Based on the fact that the single cell of the Amoeba can split in half, the correct answer is The student is correct; amoebas are probably alive because they have reproductive capabilities and create offspring through reproduction.

<h3>Why is the student correct about Amoebas?</h3><h3 />

An organism is considered to be alive due to various reasons and one of them is whether the organism has reproductive capabilities and can therefore reproduce and create offspring.

Even though the Amoeba is a unicellular organism, it can still reproduce asexually which means that it can reproduce without the need for another organism of its kind like it does when it splits itself in two.

The builder of a house on a cliff overlooking the ocean should be concerned about what
Anna11 [10]

Answer:

Erosion

Explanation:

Building a house on a cliff is a very trick thing. The cliffs usually are not composed of hard rocks, but instead are usually composed of sedimentary rocks which are much softer and less stable on the long run. The cliffs are also exposed to heavy erosion, in the lower parts because of the waves, in the higher parts because of the winds. The erosion makes the cliffs slowly fall apart, and occasionally even crumble down, so a builder that would build a house on a cliff should be wary of all these things and construct the house where it is the safest for the long run.

How did your prediction compared to the actual changes in sea level? What have you learned about sea level variations?
tatuchka [14]

1. My predictions about the changes in sea level have been relatively close to the actual rise of the sea waters, though it has been different than the general predictions of the numerous models of the countries. The predictions that I have made about the rise of the sea level have been based on the rate of melting of the polar ice, but also on the isostatic rebound that occurs because of it, and the influence that the greenhouse gasses have on the global temperature. The estimates that I made were showing a rise of only few centimeters, unlike the several meters predicted by most of the models. The closest model to what I have predicted is the Russian model, which is very different than the others.

2. The sea level variations are not very easy to predict, nor do they have any particular cycle that is repeating on approximately the same time. There are numerous factors that influence the variations of the sea level, such as the global temperature, with higher temperature meaning higher sea levels, and lower temperature meaning lower sea levels. The isostatic rebound of the continental land masses should also be taken in consideration, as the continents lift up when they don't have pressure on top of them from the ice, and sink down when they do have large ice masses on them, thus it can influence where the water can penetrate and where it can't. The position of the landmasses, composition of the atmosphere, as well as the geological activities, all have big influence on the variations of the sea levels, be it going up or down.
