Leviafan [203]

A. the height of the cactus plants

Explanation:

The dependent variable in this experiment designed to test this hypothesis is the height of the cactus plants.

In a hypothesis statement, we can always deduce the dependent and independent variables.

  • Independent variables do not rely on other variables. They are usually the cause of the phenomenon observed in an experiment. In this experiment, it is the rainfall on the cactus plant.
  • Dependent variable is that variable that relies on the independent variable. It is usually the effect of changes in independent variable.
  • The height of the cactus plant depends on the amount of rainfall in an area.

Answer:

See explanation

Explanation:

1 ) Al has physical and chemical properties, similar to Boron, because It's also part of group 13, also called the boron group. The elements are characterized by having three valence electrons.

2) Lithium is in group 1. This means it has 1 valence electron.

Nitrogen has 7 electrons. The first shell can only have 2 electrons, so the second and outer shell has 5 electrons. Those 5 electrons are the 5 valence electrons;

Neon is a noble gas, it's in the stable noble gas configuration. This means it has 8 valence electrons.

Oxygen = non-metal because it's a gas

Silicon = metalloid

Helium = non-metal because it's a gas

Arsenic = metalloid

Sodium = it's an (alkali) metal, It is physically silver colored and is a soft metal of low density. Pure sodium is not found naturally on earth because it is a highly reactive metal

Chlorine = non-metal

Tin = Is a soft,  ductile and highly crystalline silvery-white metal

Boron = it does conduct electricity. Its chemical properties are mostly, but not entirely, and non-metallic

lead = is a heavy metal that is denser than most common materials

Radon = metalloid

Cesium = It is a soft, silvery-golden alkali metal

Carbon = non metal

Period

⇒ Horizontal from left to right

⇒ same number of atomic orbitals

⇒period = row

Group

⇒ vertical colums

⇒same number of valence electrons

⇒ same physical and chemical properties

Katarina [22]
The movement of salt molecules in a system and surroundings that have different concentrations follow the osmosis principle. Osmosis is the phenomena where molecules move from lower concentration to higher concentration through a sem-permeable membrane. when the concentration is higher outside, then answer is C. molecules <span>move out of the cell, and the cell will shrink or shrivel.</span>
