Answer:
There are 4 different fundamental states of matter: solid, liquid, gas, and plasma.
The atoms/molecules that make up a solid are packed <u>tightly</u> together and arranged in regular, repeating patterns. They are held firmly in place by their attractive forces and their <u>low kinetic energies</u> but do vibrate within a limited area. Solids, have a <u>fixed</u> shape and volume.
In liquids, the atoms/molecules have a moderate kinetic energy and flow easily around one another. They are kept from flying apart by attractive forces between them. Liquids have a fixed <u>volume</u> but assume the <u>shape</u> of their containers.
Atoms/molecules in gases fly in all directions at great speeds. Due to this <u>high</u> kinetic energy, attractive forces between them are <u>insignificant</u>. Gases assume the volume and shape of their containers.
Lastly, plasma is the state of matter with the highest thermal energy. It is made up of free electrons and the positive ions from which they came. The electrons freely move around within this system of positive ions in a similar way to <u>gases</u> . Plasmas are strongly influenced by electric and magnetic fields due to the charged particles.
<span>Carbon dioxide is a colorless and odorless gas that is vital to life on Earth. This naturally occurring chemical compound is made up of a carbon atom covalently double bonded to two oxygen atoms. Carbon dioxide exists in Earth's atmosphere as a trace gas at a concentration of about 0.04 percent by volume. Natural sources include volcanoes, hot springs and geysers, and it is freed from carbonate rocks by dissolution in water and acids. Because carbon dioxide is soluble in water, it occurs naturally in groundwater, rivers and lakes, in ice caps and glaciers and also in seawater. It is present in deposits of petroleum and natural gas.</span>
Answer:
The correct answer would be (D) Blue jays and finches nest in the same oak trees.
Competition is a type of ecological relationship between the organisms of the same or different species in which they compete for the same resources.
Limitation of any one resource used by both the organisms would become the limiting factor.
For example, blue jays and finches depend on the same oak tree for their nesting. Thus, limitation or decrease in the number of oak trees can become the limiting factor.
your answers are b., travel, & E., loosely packed soil
Answer: Photosynthesis
Explanation: Photosynthesis removes CO2 from the atmosphere and replaces it with O2. Respiration takes O2 from the atmosphere and replaces it with CO2.
