Since fibrous roots grow from the side of monocot plants, the plant roots observed on the corn stalk are fibrous roots.
<h3>What are fibrous roots?</h3>
Fibrous roots are roots of plants which are usually seen on the surafce above ground and which grow from the side of plants.
Monocotyledons such as corn have fibrous roots.
The fibrous roots help to provide support and strength to the plant.
Therefore, the plant roots observed on the corn stalk are fibrous roots.

Answer:
an atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
Explanation:
An ion is defined as an atom or molecule that has gained or lost one or more of its valence electrons, giving it a net positive or negative electrical charge. In other words, there is an imbalance in the number of protons (positively charged particles) and electrons (negatively charged particles) in a chemical species
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>
<span>Here square frequency of recessive alleles r^2 = 160/1000 = 0.16
Therefore r = 0.16
Since r + d = 1; d = 1-0.16 = 0.84</span>
