What is a scientific theory?

A structured explanation for a group of facts or phenomena observed in the natural world is called a scientific theory. It often incorporates a scientific hypothesis and/or scientific laws.

The definition or meaning of the word 'scientific theory is different from the definition of the word 'theory' that people use casually.

The use of the word theory by scientists is different from how it is commonly used by the general public. Most common people use the word 'theory' when they mean to describe an idea or a hunch that someone has. For scientists, 'theory' refers to the way of interpreting facts.

A scientific theory does not mean the end of the scientific method. Scientific theories are proven or rejected, just like hypotheses are. Also, these theories are continuously improved or modified if more information regarding them is known. This helps to keep the accuracy of the prediction to become greater over time.

Therefore the correct option is D.

Describe Cohesion and Surface tension, and explain how the structure of water is responsible for these properties.

Answers

Answer:

Cohesive forces are responsible for surface tension, a phenomenon that results in the tendency of a liquid’s surface to resist rupture when placed under tension or stress. Water molecules at the surface (at the water-air interface) will form

Adhesion and cohesion are water properties that affect every water molecule on Earth and also the interaction of water molecules with molecules of other substances.

Explanation:

Answer:

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.

Prophase, metaphase, anaphase, and telophase.

Explanation:

Mitosis is a type of cell division in which a single mature parent cell is divided into two daughter cells having double number of chromosomes and identical to parent cell. There are four phases of mitosis which are prophase, metaphase, anaphase, and telophase. During prophase phase, chromatin condenses into chromosomes. During prophase phase, the chromosomes of the cell align themselves in the middle of the cell. During prophase phase, During prophase phase, the splitting of chromosomes occur and the separated chromosomes goes to the opposite poles of the cell. During telophase, it results in the production of two nonidentical daughter cells.

Theoretical element “A” has four isotopes. Use the data in the table to calculate the average atomic mass of the unknown element A. All steps of the calculations must be shown for credit.

Isotope Atomic Mass Abundance
A - 49 49.022 amu 89.89%
A - 48 48.031 amu 7.01%
A - 47 48.007 amu 3.00%
A - 46 46.001 amu 0.10%

Answers

From the calculations, the average atomic mass of the element is 48.85.

What is the percentage abundance?

The percentage abundance has to do with the amount of an isotope that is available in nature.

Since we have the following mass abundance;

A - 49 49.022 amu 89.89%

A - 48 48.031 amu 7.01%

A - 47 48.007 amu 3.00%

A - 46 46.001 amu 0.10%

The average atomic mass =

(0.8989 * 49.022) + (0.0701 * 48.031 ) + (0.03 * 48.007) + (0.001 * 46.001 )

= 44 + 3.4 + 1.4 + 0.05

= 48.85
