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.
Answer:
Mushrooms belong to the Kingdom Fungi.
Explanation:
Fungi are eukaryotic organisms that act as the main decomposers in the environment. Examples are yeasts, molds and mushrooms. Black truffles are aromatic edible fungi that belong to the Ascomycota phylum.
Mushrooms belong to the Basidiomycota phylum. Mushrooms are saprophytes, as they have no chlorophyll and obtain their food from metabolizing nonliving organic matter.
Edible mushrooms include commercially raised mushrooms like button mushrooms, portobello mushrooms, straw mushrooms, oyster mushrooms, shiitakes, enokitake, etc and wild-harvested mushrooms such as black trumpets, milk mushrooms, porcini mushrooms, morels, chanterelles, etc.
Poisonous mushrooms include amanita, galerina, conocybe, lepiota, etc. They contain deadly poison which causes a range of reactions such as hallucinations, allergic reactions, digestive problems, severe organ failure, and death.

Answer:
The correct option is <em><u>A. Over time, due to evolution by means of natural selection, resistant weeds survived, reproduced, and passed on their herbicide resistant genes. </u></em>
Explanation:
Herbicides can be described as substances which are used to kill unwanted plants such as the weeds. Nowadays, selective herbicides are produces which are effective in killing the weed species and do not harm the crop plants.
But over time, the weeds get resistant to the herbicide. As the theory of natural selection says, 'survival of the fittest', the herbicide which are resistant are better adapted to live hence, they pass their genes to the offsprings. This results in the production of more herbicide resistant weeds.
