Plz me and ! which of the following statements is true? 1.cohesion plants transport water from their roots to their leaves. 2.the dissolving power of water is very important for the transport of nutrients in blood. 3.the solid form of water is more dense than the liquid form, which is why ice floats. 4.surface tension is a measure of how much water molecules are attracted to other materials.

The dissolving power of water is very important for the transport of nutrients in blood.

Explanation:

Water is often called the "universal solvent" because it can dissolve more substances than any other liquid. The dissolving power of water means that it can effectively transport nutrients, chemicals, and minerals. Plants rely on water to carry dissolved nutrients from the soil. Animals also benefit from water as a solvent.

we would need to see the picture to answer it

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
