You observe a tissue under a microscope. There appears to be a lumen on one side of the tissue. Lining this lumen, the cells see

m to have long, fingerlike projections. Beneath the projections, the cells seem to have the shape of shoeboxes and are packed tightly together. What type of tissue are you looking at?A. Simple Cuboidal EpitheliaB. Simple Columnar EpitheliaC. Stratified Squamous EpitheliaD. Transitional Epithelia

Answer:

The correct answer is A: Simple cuboidal epithelium.

Explanation:

Simple Cuboidal Epithelium: These epithelia are formed by a single layer of cuboidal cells, that are <em>as </em>tall as they are wide. They have a rounded, central nucleus.  Occasionally these cells present cilia, flagella or <em>microvillus</em> in their apical surface, lining the lumen. Microvillus are fingerlike projections.  This epithelium can be found for example in the proximal convolutes renal tubule.

What would happen on a hot day if your brain did not receive input that your body was starting to heat up
Karolina [17]

Answer:

The body will overheat

Explanation:

If the brain of an individual does not receive input that the body was starting to heat up on a hot day, <u>the setpoint temperature of the body would be exceeded and the body will overheat. If the condition persists for a while, the entire systems of the body may shut down due to overheating. </u>

Normal homeostatic response requires that the brain (the control center) receives a message from the skin (the sensor) about a rise in the body's temperature. In turn, the brain will set mechanisms that will bring the body's temperature back to normal in motion, including vasodilation of the blood vessels in the skin to allow more blood into the skin which in turn causes more heat loss to the surrounding.<em> Thus, an individual starts sweating and the evaporation of the sweat causes cooling and a return of the body to the setpoint temperature.</em>

In which case would facilitated diffusion be needed?
melomori [17]

Answer:

The voltage-gated potassium channels associated with an action potential provide an example of what type of membrane transport?

A. Simple diffusion.

B.<u> Facilitated diffusion. </u>

C. Coupled transport.

D. Active transport.

You are studying the entry of a small molecule into red blood cells. You determine the rate of movement across the membrane under a variety of conditions and make the following observations:

i. The molecules can move across the membrane in either direction.

ii. The molecules always move down their concentration gradient.

iii. No energy source is required for the molecules to move across the membrane.

iv. As the difference in concentration across the membrane increases, the rate of transport reaches a maximum.

The mechanism used to get this molecule across the membrane is most likely:

A. simple diffusion.

<u>B. facilitated diffusion. </u>

C. active transport.

D. There is not enough information to determine a mechanism.

Carrier proteins - exist in two conformations, altered by high affinity binding of the transported molecule. Moves material in either direction, down concentration gradient (facilitated diffusion). EXAMPLE: GluT1 erythrocyte glucose transporter.

Channel proteins - primarily for ion transport. Form an aqueous pore through the lipid bilayer. May be gated. Moves material in either direction, down concentration gradient (facilitated diffusion). EXAMPLES: Voltage-gated sodium channel, erytrhocyte bicarbonate exchange protein.

This might be helpful... because I don't know anything about facilitated diffusion.
