Panther and the White Tailed Deer. Since the Florida Panther is an endangered species, what would happen to the
deer population as the panther population decreases in size?
A. The deer population would decrease.
B. The deer population would not be affected.
C. The deer population would increase indefinitely.
D. The deer population would increase and then level off.

Answers

Answer:

D

Explanation:

It would be D because it would increse yes in population because the panthers are decreasing and attacking less. But, it would still level off because there are other predators who can kill the white tailed deer. Also the panther who is endangered could still atack even though theres just a few left that does not affect them from attacking. So it would increase but it would still level off.

lonic bonds tend to form between two atoms with what characteristics?​

Answers

Answer:Ionic bonds are formed through the exchange of valence electrons between atoms, typically a metal and a nonmetal. The loss or gain of valence electrons allows ions to obey the octet rule and become more stable. Ionic compounds are typically neutral. Therefore, ions combine in ways that neutralize their charges.

Explanation:

Ionic bonds tend to form between two atoms with a high electronegativity difference.

Explanation:

An Ionic bond is defined as a chemical bond in which the complete transfer of electrons occurs from one atom to another.The transfer of electrons occurs from less electronegative atom to highly electronegative atomThe high electronegativity difference between the atomsCompounds with ionic bonds categorized as ionic compounds

So, from this, we can conclude that ionic bonds tend to form between two atoms with a high electronegativity difference.

When fossil fuels, such as gasoline, are burned, they create smoke. Smoke is best described as a heterogeneous mixture of solid particles from the burning fuel dispersed in a gas – usually air. Smoke can be described more specifically as a suspension. What will most likely happen over time to smoke in the atmosphere? The solid particles will spread out and dissolve. The particles will eventually come together in a cloud and produce rain. Over time, the solid particles will settle on whatever is outside. The particles will remain mixed in the air.

What is the chemical equation?

A chemical equation can be defined as the expression of a chemical reaction in terms of the chemical symbols of the substances. A chemical equation has reactants, formed products, and an arrow indicating the direction of the reaction.

The equation in which the number of atoms of each element is equal on either side of the chemical equation of a reaction is called a balanced chemical equation.

According to the law of mass conservation, the total mass of the elements on the reactant side should be equal to the total mass of elements on the product side.

Given, the chemical equation of the reaction of nitrogen ad oxygen gas can be written as:

2N₂  +  O₂ → 2N₂O

The number of molecules of Nitrogen gas is 2 and the molecules of oxygen gas are one and the molecules of N₂O are equal to 2.
