Answer:
pests can evolve defenses against pesticides over time
Explanation:
Pesticides are chemicals employed to kill pests generally. With continuous and indiscriminate use of pesticides, they become less effective because pests population often evolve a defense mechanism against them.
<em>With each usage, more and more pest population survive. Those that survive gradually multiply and pass the survival gene to their offspring eventually giving rise to a population that is genetically insusceptible to the effects of the pesticide. This is generally referred to as evolution by natural selection.</em>
Answer Options:

d. All living things are made up of cells.
Answer:
a. Cells are the basic units of structure and function in living things.
b. New cells are produced from existing cells.
d. All living things are made up of cells.
Explanation:
Cell theory states that cell living organisms are composed of at least one cell, which are the basic unit of life.
Cells are always produced from other living cells, and cannot spontaneously generate.
However, not all cells enclose their DNA within a nucleus, prokaryotic organisms (bacteria) do not possess a nucleus but still have DNA
Basically Hershey and Chase studied bacteriophages (viruses that infect and destroy bacteria), which they got the idea from Avery who got the idea from Griffith.
so the results of Hershey and Chase's experiments were that genes are made from Deoxyribonucleic Acid.
hopefully this helps
It helps you organize your data, and so its not a complete mess when you need to refer back to it. It will help you organize and not confuse and miscompare information. It also looks better and looks like you know what you're doing.
Because of the pigments. Like chlorophyll pigment is always green. Specific colors of light and reflect other colors, depending on their chemical structure.
