Explanation:
Horn can be simply defined as the pyramidal peak that is formed at the high elevated region that are mostly covered by ice. This is formed when the glaciers erodes three or more aretes.
Mass wasting refers to the downward movement of rocks, or broken fragments or sediments that are primarily caused due to the influence of gravity.
Moraine usually refers to the accumulation of sediments and rocks that are mixed with ice, and these are unsorted in nature and are deposited when these particles are carried downward by the movement of glaciers.
Striations can be simply defined as scratch marks or grooves that are formed when rock undergoes thrusting or faulting.
Talus is defined as the accumulation of broken rock fragments that are found at the base of a mountain or cliff.
B = 0.4
b = 0.6
Explanation:
From the question we derive that;
BB = 16%
Bb = 24%
The gene frequency for BB = 16/100 = 0.16
To find allelic frequency of B;
B = √0.16 = 0.4
Remember Hardy Weinberg rule that all allelic frequencies of a gene must sum up to 1;
p + q = 1
If p = 0.4
q = 1 – 0.4 = 0.6
b = 0.6

The Correct Answer : <u>Flooding the fields causes the soil to degrade so weeds cannot take root.</u>
Rice has a submerged growth state while most weeds do not. Therefore, flooding rice fields reduces the growth of these less robust pests without negatively affecting the rice crop. Flooding the fields also deters many kinds of vermin that would otherwise live in the soil and harm the rice plants because they cannot breathe underwater.

<h3>What is Pesticides?</h3>
Pesticides are chemicals that may be used to kill fungus, bacteria, insects, plant diseases, snails, slugs, or weeds among others. These chemicals can work by ingestion or by touch and death may occur immediately or over a long period of time.
<h3>What is Herbicides?</h3>
Herbicides are used to kill undesirable plants or “weeds”. Some herbicides will kill all the plants they touch, while others are designed to target one species.
<u />
Therefore, we can conclude that the correct option is B.
