You have a planar bilayer with equal amounts of saturated and unsaturated phospholipids. After testing the permeability of this

membrane to glucose, you increase the proportion of unsaturated phospholipids in the bilayer. What will happen to the membrane's permeability to glucose?

Answer: The increase to the permeability to glucose.

Explanation:

Membranes fluidity increases if there is addition of unsaturated proportion in the membrane. This increase in the fluidity of the membrane the glucose molecules will pass more easily through the cell membrane.

The cell membrane of the cells are semi permeable as it does not allows all the molecules to pass through it, it allows only certain molecules to pass through it.

Hence, addition of unsaturated phospholipids in the cell membrane will increase the permeability towards glucose.

With the exception of sensory neurons, the role of a neuron's __________ is to carry information toward the cell body, whereas t
Reika [66]

Answer:

d. dendrites; axon

Explanation:

The structure of a neuron contains the stem-like structure at one end, the cell body contains the nucleus and the long tube-like structure covered with a myelin sheath called axons.

The axons carry the signal away from the cell body in sensory neurons and the dendrites carry the information towards the cell body.

The signals are transmitted in the form of electrical signals which gets converted into the chemical signal at the synaptic junction through the neurotransmitters released by the synaptic knobs.

Thus, Option-D is the correct answer.

What is the effect of the following changes on the O2 affinity of hemoglobin?
Vladimir79 [104]

Answer and Explanation:

The affinity of hemoglobin for Oxygen is controlled when the ligands H^{+} , CO_{2} and BPG binded.

The binding of every ligand moves the saturation curve of  Oxygen towards right—that is, the oxygen affinity of hemoglobin is decreased within the sight of ligand.  

(a) A pH drop will expand the oxygen affinity to myoglobin and decline the oxygen affinity for hemoglobin. This implies less oxygen will be taken by the lungs and more will be off stacked at the tissues diminishes the affinity.

(b) An abatement in the partial pressure of CO_{2} will expand affinity of oxygen to hemoglobin and diminishes the affinity of oxygen for myoglobin expands the affinity.

(c) An expansion in BPG levels diminishes the affinity of oxygen for hemoglobin and expands oxygen's affinity for myoglobin  diminishes the affinity.  

(d) As CO ties to a couple of subunits of a hemoglobin tetramer, the affinity for oxygen is expanded generously in the rest of the subunits. Subsequently, a hemoglobin tetramer with two bound CO particles can productively tie oxygen in the lungs—yet it discharges almost no of it in the tissues.

Natural resources are not required for all energy producing technology. Please select the best answer from the choices provided
laila [671]
<h2>Answer:</h2>

<u>The statement is</u><u> False</u>

<h2>Explanation:</h2>

Energy production needs a source. These sources may be renewable or non renewable but in both cases they are present naturally in the universe and we cannot make anything without using natural resources. For example if we use nuclear energy we need radioactive minerals. Similarly water, air, solar energy, coal, fossil fuels, natural gas or whatever source we take, they are all present in nature already so natural resources are required for all energy producing technology whatever the industry we take.

Using context clues, what does “ferrying its newly-gained energy with it “ mean when talking about convection?
finlep [7]

The term "ferrying its newly-gained energy with it" means that the fluid carries the energy it acquired as it rises during convection.

Convection is a mode of heat transfer in which energy is transferred by the bulk movement of particles from one point to another. During convection, a fluid is heated and its particles acquire energy, These energetic particles now move upwards and are replaced by less dense fluid at a lower energy.

The term ferrying its newly-gained energy with it, implies that the heated particles carry the energy they have gained with them as they rise during convection.
