The particles that make up matter do not change during a(n)?

1 answer:

5 0

The particles that make up matter are the atoms.

Atoms do not change during a chemical change. They do not either during a physical change.

During a chemical change molecules change but not the atoms. The atoms separate from the original molecules and form new molecules. Then moleculas change but atoms remain being the same before and after the chemical change.

For example, atoms of oxygen in molecules of O2 combine with atoms of hydrogen in molecules of H2 and they form the molecules of water H2O.

The atoms of O in O2 are the same atoms of O in H2O and the atoms of H in H2 are the same atoms of H in H2O. The molecules changed, from H2 and O2 to H2O, but the atoms are the same.

labwork [276]

Answer:

Closely related species occupying the same niche.

Explanation:

Competitive exclusion principle states that the two species cannot exist together if they share the same resources. The one species completely exclude the other species from their niche.

Competitive exclusion principle generally occurs between the species that occupy the same niche and are closely related with each other. The competitive exclusion principle first explained between the species P. aurelia and P. caudatum.

garri49 [273]

Answer:

Hey mate......

Explanation:

This is ur answer.....

1A) There are 2 ways:-

• Anaerobic Respiration.

The anaerobic respiration process takes place in the absence of oxygen. 

• Aerobic Respiration. 

In aerobic respiration, breakdown of pyruvate takes place in the presence of oxygen to give rise to 3 molecules of carbon dioxide and water.

2A) Oxygen is transported from lungs to body cells in the form of oxyhemoglobin . the main 2 gases exchanged are 02 & C02 . 02 is absorbed by blood capillaries from lungs alveoli by diffusion while C02 is absorbed by blood alveoli from blood capillaries by diffusion.
