Answer:
0
Explanation:
The parent plants are each heterozygous for round seeds and heterozygous for wrinkled seeds. Each parent contributes one allele to the offspring plant. As such, the only possible genotype of all offspring plants would be Rr (which would have round seeds as round seeds allele is dominant). Hence, no offspring can have wrinkled seeds.

Answer:
d. an onblique muscle layer
Explanation:
The alimentary canal has four main layers:
Mucosa (innermost layer which surrounds the lumen), submucosa (connective tissue with blood vessels, lymphatics, and nerves), muscular layer, serosa ( outermost layer of connective tissue).
Muscular layer is subdivided into:
• the inner- arranged in circular rings, prevents food from travelling backward
• outer layer- arranged longitudinally, shortens the tract.
The stomach has an extra layer called inner oblique muscular layer (churning function).
The youngest layer present on the top whereas the oldest layer is present at the bottom.
<h3>Which layer is youngest or oldest?</h3>
Quartz or calcite lines in layers of rock indicate that rock has minerals.
The youngest rock layers are present on the upper while on the other hand, the oldest are present on the bottom side because new layers are formed when there more sediments deposited on the layer.
So we can conclude that the youngest layer present on the top whereas the oldest layer is present at the bottom.
