Is water polar or nonpolar​
statuscvo [17]

Answer:

Polar

Explanation:

A water molecule, because of its shape, is a polar molecule. That is, it has one side that is positively charged and one side that is negatively charged. The molecule is made up of two hydrogen atoms and one oxygen atom. The bonds between the atoms are called covalent bonds, because the atoms share electrons. The hydrogen atoms have one electron each.

"DNA denatures at a higher temperature than does protein, yet its structure depends on relatively weak hydrogen bonds. Why the d
Reika [66]

The option are not given and the options are:

Proteins are denatured by breaking covalent bonds.

Linear molecules like DNA are inherently stable.  

Individual hydrogen bonds may be weak, but DNA structure is stabilized by many thousands or millions of these bonds - far more than found in proteins.

The statement is incorrect; it actually takes far more energy to denature proteins than it does to denature DNA.

Answer:

The correct answer is- Individual hydrogen bonds may be weak, but DNA structure is stabilized by many thousands or millions of these bonds - far more than found in proteins.

Explanation:

Proteins become denatured when it looses its three-dimensional structure. Disulfide bond and hydrogen helps in stabilizing the three-dimensional structure of proteins and if these bonds break due to any factor protein lost its structure and function.

DNA is made up of a large amount of hydrogen bond because in AT base-pairing two hydrogen bonds are required and in GC base pairing three hydrogen bonds are required. Therefore it can be concluded that as more hydrogen bonds stabilizes DNA than protein its melting temperature is higher than protein.

const2013 [10]
The data given are 
            melting point            density 
<span>Zinc        419.53 oC              7.134
Nickel      1455oC                 8.912
Copper  1084.62oC              8.96
Silver        961.78oC           10.501
Gold        1064.18oC          19.282

density is the mass per unit volume. Melting point is determined by the intermolecular forces between particles in the solids.
We </span>have been asked to find which cube weighs the most 
density = mass/volume 
when volume is constant for all the metals, then density is directly proportional to mass. Therefore metal with highest density has the highest mass.
from the given metals, metal with highest density is Gold.
correct answer is Gold.

Greeley [361]
<span>Eating nonfood items like clay, erasers, and chalk during pregnancy is known by the medical name of geophagy. Pregnant women does crazy things that gives them a weird number of choices when it comes to food cravings. The main reason is to protect her and the baby from harmful microorganisms and toxins and to suffice the lack of vitamins. Clay though has a high mineral content, that is rich in magnesium, copper, iron and calcium. While it may be weird, these minerals are the fundamentals of a human diet especially during pregnancy.</span>
