Lesson 01.04 Properties of Water
ryzh [129]

Answer:

1= In living organisms cells are composed of water or we can say that water is one of the important constituent of cells.

2= Hydrogen bonding import man properties to the water such as cohesion, high heat of vaporization, high heat capacity etc.

3= Because of high polarity, all polar substance get dissolve and make it universal solvent.

Explanation:

Solvent is the that part of solution which is present in large proportion and have ability to dissolve the solute. In simplest form it is something in which other substance get dissolve. The most widely used solvent is water, other examples are toluene, acetone, ethanol, chloroform etc.

Water is called universal solvent because of high polarity all polar substance are dissolve in it. Hydrogen is less electronegative while oxygen is more electronegative and because of difference in electronegativity hydrogen carry the partial positive charge while oxygen carry partial negative charge.

Hydrogen bond:

The hydrogen bond is the attraction between the toms which already take part in the other chemical bons. The one atom is hydrogen while other may be oxygen, nitrogen or fluorine.

The hydrogen bonding in water import man y properties in it such cohesion, high heat of vaporization, high heat capacity etc. The hydrogen bond hold the water molecules together.

Water create electrostatic interaction with other polar molecules. The negative end of water attract the positive end of polar molecules and positive end of water attract negative end of polar substance and in this way polar substance get dissolve in it.

Example:

when we stir the sodium chloride into water the cation Na⁺ ions are surrounded by the negative end of water i.e oxygen and anion Cl⁻ is surrounded by the positive end of water i.e hydrogen and in this way all salt is get dissolved.

Describe the movement of particles within solids, liquids, and gases.
Paladinen [302]
Particles in solids move ever so slightly. They are not completely at rest, but since they are so packed together it’s difficult for them to move. That’s what makes a solid a solid. Particles in liquids slide and move past each other fairly quickly, and have space to move. Particles in gases are the most spread apart, and because of this, they move the quickest. Hope this helped.

What is the study of how the structure and function of genes interact with our environment to influence behavior called?.
Anettt [7]

Epigenetics is the study of how the structure and function of genes interact with our environment to influence behavior.

In addition to your surroundings and habits, such as what you eat and how much exercise you get, your genes play a significant part in determining your health. The field of epigenetics investigates how environmental factors and behavior may alter how your genes function. Gene-environment interactions that result in the expression of different phenotypes throughout development are the basis for the initial usage of the term "epigenetics." To turn on or off the genes that cause long-lasting alterations linked to the differentiation of various cell types, epigenetic processes are frequently used.

Epigenetics is the study of how DNA sequences are maintained as genes are controlled by cells. DNA alterations known as epigenetic changes control whether or not genes are activated.
