Answer:

Linings of hollow organs

Explanation:

Smooth muscle cells are usually found in the lining of hollow organs such as all arteries and veins, wall of stomach, uterus, urinary bladder, digestive system etc. The cells of these linings are spindle shaped and consist of a nucleus at the center which lacks striations.  

They work as a housekeeper and are under involuntary control except the heart. They lack striation because of irregular arraying of actin and myosin filament along the length of the cell.

Why are most of the stomata on the bottom of the leaf
larisa86 [58]

Answer: Stomata plays very crucial roles in plants. During photosynthesis, gas exchange takes place via the stomata. Water also evaporates from plants through the stomata. In plants, most of the stomata are usually on the bottom of the leaf IN ORDER TO PREVENT EXCESSIVE LOSS OF WATER.

During the day, the sunlight falls on the leaf directly and draws water from the plants. Locating the stomata at the underside of the leave reduces the amount of water that can be lost through excessive evaporation. Also, locating the stomata on the underside of leaves prevent  the leaves from taking in too much water during rainfall.

A dot is drawn every second to show the position of a toy car coasting up a ramp. Which statement best describes the motion of t
lbvjy [14]

It is speeding up because more distance is covered every second.

Explanation:

The car can be described to be speeding up because more distance is covered every second.

From what we understand about velocity and acceleration, the car is accelerating through the ramp.

It's velocity is increasing with every second it covers.

This will invariable reduce the time between each distance covered.

Originally, the toy car starts with a low initial velocity or speed. As it gains acceleration, the speed will increase and more distance covered per seconds.

This is why the dots clustered towards the end of the diagram. The positions are getting closer and distance reducing per seconds.
