Pectinate muscles are found on the internal walls of the right and left atria. The correct option is C.
<h3>What are pectinate muscles?</h3>
Pectinate muscles are ridge-like muscle elevations. They are parallel to each other and resemble comb teeth. They can be seen clearly inside the right atrium.
Pectinate muscles are found on the internal walls of the right and left atria.

Answer:
Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels.In addition, gravity is weaker at the equator due to centrifugal forces produced by the planet's rotation. It's also weaker at higher altitudes, further from Earth's centre, such as at the summit of Mount Everest
Desert biomes would benefit them if they can store water.
The answer is true.
Transitional epithelium of the urinary bladder (urothelium) is a type of stratified (multilayered) epithelium. Layers of epithelial cells in this tissue can contract and expand in order to adapt to the degree of distension needed.
Layer of basal cells (basal layer) consists of cuboidal or columnar cells. Superficial layer, on the other hand, can vary depending on the degree of distension: so, when the bladder is not stretched, the cells are cuboid, but when the bladder is filled with urine, stretched, the cells are squamous.
