The answer is C) selective breeding. This means that humans are deciding what to breed which means this is not a natural selection, but rather an artificial selection.
The properties are:-
1. Water is polar. Water molecules are polar, with partial positive charges on the hydrogens, a partial negative charge on the oxygen, and a bent overall structure. This is because oxygen is more electronegative, meaning that it is better than hydrogen at attracting electrons.
2. Water is an excellent solvent. Water has the unique ability to dissolve many polar and ionic substances. This is important to all living things because, as water travels through the water cycle, it takes many valuable nutrients along with it!
3. Water has high heat capacity. It takes a lot of energy to raise the temperature of a certain amount of water by a degree, so water helps with regulating temperature in the environment. For example, this property allows the temperature of water in a pond to stay relatively constant from day to night, regardless of the changing atmospheric temperature.
4. Water has high heat of vaporization. Humans (and other animals that sweat) use water’s high heat of vaporization to cool off. Water is converted from its liquid form to steam when the heat of vaporization is reached. Since sweat is made mostly of water, the evaporating water absorbs excess body heat, which is released into the atmosphere. This is known as evaporative cooling.
The answer is C hope this helps!
When a molecule is made up of one sugar unit, its called a monomer.
Eg. Glucose, galactose, fructose
When a molecule is made of more than one sugar units, its called a polymer.
Eg. Cellulose, glycogen
Polymers are usually macro molecules.
Explanation:
To calculate the total magnification , of the binocular microscope -
The image of the object under observation only go via only one ocular and then travel to both our eyes ,
And the arrangement of lenses of the binocular is in way , that they are kept side - by - side and are not in a proper alignment with each other .
