The correct layer is "<span>there is an additional third oblique layer of smooth muscle".
The muscularis externa of the stomach is purely smooth muscle (no skeletal muscles or other striated muscles) composed of three layers; inner oblique, middle circular, and external longitudinal layers. Plicae circularis can only be found in the intestines, not in the stomach.</span>
Answer:
Yes, the environment and the heritage both plays very crucial role in defining the evolution. But how? let's start it here.
Explanation:
- As per the Charles Darwin theory of natural selection, organisms that better adapt to changes can survive very well.
- For example In earlier times, snakes used to have limbs but they are just useless for them and they are not using those limbs so in next generations snakes have vestigial remnants of limbs.
- Another example we can study here is of mice, such as mice are nocturnal animals so they don't have vision capabilities and over generations they adapt a change due to their predatory nature and came with an affect of better hearing capabilities.

Oxygen
Explanation:
It's air. why would it carry water
Most cells grow, perform the activities needed to survive, and divide to create new cells. These basic processes, known collectively as the cell cycle, are repeated throughout the life of a cell. Of the various parts of the cell cycle, the division portion is particularly important, because this is the point at which a cell passes its genetic information to its offspring cells. In many situations, division also ensures that new cells are available to replace the older cells within an organism whenever those cells die.
Prokaryotic cells, which include bacteria, undergo a type of cell division known as binary fission. This process involves replication of the cell's chromosomes, segregation of the copied DNA, and splitting of the parent cell's cytoplasm. The outcome of binary fission is two new cells that are identical to the original cell.
