The plasma membrane is a semi-permeable membrane that allows the movement of a molecule from inside to outside of the cell and vice versa.

Further Explanation:

The plasma membrane is mainly composed of cholesterol, protein, and phospholipids. They move easily in the membrane and maintain the fluid nature of a membrane. The main component of the plasma membrane is phospholipids that are made up of fatty acid, phosphate, and glycerol. These phospholipids make two layers of phospholipids that are mainly known as the lipid bilayer. This bilayer makes the plasma membrane semi-permeable and helps in the transport of molecules from inside to outside and vice versa.

 

Other components of the lipid bilayer are carbohydrates and protein. They also play a major role in the plasma membrane because they help in cell signaling. Glycolipids are present on the outer side of the cell membrane. The membrane of the cell also plays a significant role in protecting the cell from the exterior environment and acts as a barrier.

The function of the semi permeable membrane is to allow substances to diffuse (transport) across it, because its only semi permeable the substance are able to cross. If it was a non permeable membrane it wouldn't allow the transport of substances.

A client with suspected myasthenia gravis is to undergo a test with edrophonium. the client asks if edrophonium can be used to t
olga nikolaevna [1]

The correct answer is: the short half-life of edrophonium makes it impractical for long-term.

Edrophonium is used for the diagnostic of myasthenia gravis. In patient with myasthenia gravis, the body produces autoantibodies which inhibit nicotinic acetylcholine receptors in the neuromuscular junction. Edrophonium, on the other hand, is acetylcholinesterase inhibitor which blocks the effect of acetylcholinesterase enzymes (AcH stays in synaptic cleft).

Substitution for the edrophonium is pyridostigmine which is also acetylcholinesterase inhibitor but with long-term maintenance.

In maize, a dominant allele A is necessary for seed color, as opposed to colorless (a). Another gene has a recessive allele wx t
Gelneren [198K]

Answer:

  • 1/2 Aa Wx wx (colored seeds, normal starch)
  • 1/2 aa Wx wx (colorless seed, normal starch).

Explanation:

  • A (colored seed) is dominant over a (colorless)
  • Wx (normal starch) is dominant over wx (waxy)

Both loci are independent.

A <em>Aa WxWx </em>individual was test crossed (crossed with a homozygous recessive <em>aa wxwx</em> individual).

  • The homozygous recessive can only produce <em>a wx </em>gametes.
  • The dihybrid individual can produce two types of gametes, all of them with the same frequency because the genes segregate independently: 1/2 <em>A Wx </em>and 1/2<em> a Wx </em>

<u>The possible offspring resulting from the combination of those gametes is:</u>

  • 1/2 Aa Wx wx (colored seeds, normal starch)
  • 1/2 aa Wx wx (colorless seed, normal starch).
