It’s because they are polar. Nonpolar molecules move through the membrane easily, while polar molecules, such as water, move against the concentration gradient and thus move slower.

Squamous epithelium, sperm cells, smooth muscle, or human red blood cells:
polet [3.4K]

Answer:

1. sperm cells: cell has a flagellum for movement

2. smooth muscle: cells have an elongated shape (tapered at each end)

3. Squamous epithelium: cells are close together

4. Human red blood cells: cells are circular

5. Squamous epithelium cells are thin and flat, with irregular borders

6. Human red blood cells: cells are anucleate (without a nucleus)

7. smooth muscle: longest cell

Explanation:

  • <em>Sperm cells</em>: Active and morphologically specialized cells. They characterize as having an elliptic head mostly occupied by the nucleus, and a tail of about 55 micrometers that moves impulsed by a motor dynein protein that uses ATP energy.
  • Smooth muscle cells: Fusiform cells. Long and tapered at the extremes. Located in organs and viscera, and in vessel walls, where involuntary maintained slow contractions are needed. Although they are the longest cells, their length depends on the organ where they are located. They might reach up to 500 microns.
  • Squamous epithelium cells: The wide and length of the cells supere their height. Some of them suffer a process of keratinization from being exposed to dehydration and touch.  
  • Red blood cells: Red blood cells or erythrocytes are biconcave disks-shaped, with no nucleus, and very small. These are flexible cells that might move along in the smallest capillaries. Hemoglobin provides the typical red color. The red blood cell size and number vary among species.

In the lateral projection of the elbow, the arm should be flexed so that the forearm and humerus form an angle of?
Daniel [21]

lateral projection of the elbow, the arm should be flexed 90 degree .

The lateral view is an additional view obtained at virtually every diagnostic evaluation. A lateral view may be obtained as a mediolateral view (ML) or lateromedial view (LM) view depending on where the imaging tube and detector are located.

Position of part The elbow joint should be flexed 90 degrees and positioned laterally in a lateral view radiograph. A lateral radiograph of the elbow requires the elbow to be flexed 90 degrees with the forearm and humerus laying flat on the table . Lateral view is important because It clearly displays these areas and is especially useful in detecting lower-lobe lung disease, pleural effusions, and anterior mediastinal masses.
