The correct answer is A) They all have similar chemical properties.
Explanation:
In chemistry, the periodic table organizes visually the chemical elements. In this, elements are arranged according to different features. In the case of families of the elements, these refer to elements organized in the same column, for example, elements that are in column 18 form a family called noble gases.
These elements form a family because they have chemical properties; in the case of noble gases, this includes similar reactivity and physical features such as color and odor. Besides this, the elements of one family share a similar electron configuration but not the same number of electrons. This means, from the options given the one that identifies the elements that belong to a family is "They all have similar chemical properties".
If the colored spheres are solutes, the overall direction of water would be out of the cell based on the principle of osmosis.
<h3>What is osmosis</h3>
It is the movement of water molecules from the region of high water potential (low solutes) to the region of low water potential (high solute) through a selectively permeable membrane.
In the illustration, there are more colored spheres outside of the cell than inside of it. This means that there are more solutes outside the cell (lower water potential) than inside of the cell (higher water potential).
Thus, water will move from the inside of the cell to the outside until an equilibrium is established.

Answer:
The representative particle for an element is AN ATOM.
Explanation:
Representative particle of a substance refers to the smallest unit of that substance, which can not be broken down into smaller particles. The representative particles of an element is an atom, because each element is made up of atoms, which are the smallest unit of that element; they can not be broken down further.
A representative particle is chemically identical with the parent element and will have all the properties of the parent element.
Answer:
Faster hydrogen burning means the star will grow larger and more luminous to allow the extra energy created to escape
