Genotype: 50% Aa and 50% aa

Explanation: Using a punnet square, we can figure out that the mother is recessive and the father is heterozygous. Putting the mother at the top of the square and the father on the side, you end up with the results above by crossing each square with the corresponding letters. It's okay if the letters end up backwards. Just be sure to face them the right direction, capitals being first once you finish.
Hope this helps!
Answer:
D
Explanation:
The gradient in bed load is mostly made up mostly of gravels and sands, broken down versions of larger boulders and rocks, which are most commonly found in mountainous areas. Streams with low gradients cannot carry bed load down stream because it moves slowly and without much force. Gravels and sands couldn't move downstream because the water flow isn't strong enough to move them or to keep them in motion.
Biodiversity hotspots are the richest and most threatened reservoirs of life on Earth. Thus, the correct option is D.
<h3>What are Biodiversity hotspots?</h3>
Biodiversity hotspots may be defined as the regions of the earth which are rich in biodiversity and possesses the following criteria:
- The area should support greater than 1500 endemic species of flowering plants or 0.5% of total plants.
- It possesses a high degree of threat, exploitation, and biodiversity.
- It must have lost about 70% of the original habitat.
- A high degree of endemism (restricted habitat).
Therefore, Biodiversity hotspots are the richest and most threatened reservoirs of life on Earth. Thus, the correct option is D.
