Answer:
" Under cultivation, the A horizon broadly aligns with the topsoil and the B with the subsoil. The parent material below these is the 'C' horizon and where there is an underlying unweathered rock layer, often known as bedrock.
Explanation:
The answer is I, II, III and IV. Scientific investigation is the way in which
scientists and researchers use a systematic approach to answer questions about
the world around us. They may want to explore new ideas, gather evidence or
prove or disprove previous results.

a. new source of fresh water <span>
Other choices are:
</span>
<span><span>b. less access to medicine </span>
<span>c. a higher birthrate </span>
d. a higher fertility rate
New source of fresh water </span>would most likely increase the carrying capacity for humans in a certain region. Water plays many important roles in the ecological and environmental systems, and also in humans. In cellular activities and organismic activities, water is used primarily.
For example,
Water is produce when glucose and fructose undergo a condensation process. The water is removed by the combination of hydrogen and a hydroxyl together. Glucose and Fructose forms a substance called glycosidic linkage. And hydrogen and hydroxyl is separated from glucose and fructose. When Hydrogen and hydroxyl is combined, they create H2o or water.<span> </span>
Answer;
-Central conic vision
Explanation;
-Central vision is when our eyes focus straight ahead, allowing us to drive, read, and see details sharply.
-Central vision only covers about three degrees of our visual field, but it allows us to make very important judgments like estimating distance and understanding details in the path ahead.
Our sharpest, clearest vision is called central conic and is only about 3 to 5 degrees. This is our most focused vision where we can identify details and color
