Choose 1 answer:

(Choice C, Checked, Correct)

CORRECT (SELECTED)

Surface tension allows water to support small objects if they are placed carefully on its surface.

Surface tension is the tendency of a liquid’s surface to resist rupture when placed under tension or stress. If a small object is placed carefully on its surface, the tension created by the hydrogen bonds in the water can often prevent the object from sinking.

This is because in a food chain , energy flow from one trophic level to another. The producer which include plants are the source of energy which they manufacture good in the presence of light energy from sun.

A piece of glass is immersed in a liquid. It proceeds to float on the liquid's surface. This shows that the density of the glass
tamaranim1 [39]

Answer: b) Less dense

Explanation:

Differences in density is one reason objects float or sink.

An object more dense than the fluid in which it is immersed will sink, while objects less dense than the fluid in which it is immersed will float to the surface.

But objects floats at constant level if the density is equal to the density of the fluid in which it is immersed; it neither rises nor sinks in the fluid in this case.

The atomic number of nitrogen is 7. How many protons, neutrons, and electrons make up an atom of Nitrogen-15?
earnstyle [38]
<h2><u>Answer:</u></h2>

A nonpartisan iota of Nitrogen has a mass of 18. There are 7 protons in the core of this iota. What number of neutrons, complete electrons, and valence electrons are available  

Nitrogen 15 has a nuclear mass of 15. The mass number is # protons in addition to # of neutrons, so for N-15 mass is 15 and the protons are dependably 7 so there must be 15-7=8 neutrons. N-15 has 7 electrons since it has 7 protons and p = e.
