<span>Let's consider a scenario in which the resting membrane potential changes from −70 mV to +70 mV, but the concentrations of all ions in the intracellular and extracellular fluids are unchanged. Predict how this change in membrane potential affects the movement of Na+. The electrical gradient for Na+ would tend to move Na+ Outside the cell (extracellular) while the chemical gradient for Na+ would tend to move Na+ Inside the cell (intracellular).

The electrical gradient is defined as the + goes to the - and the - goes to the +
Na + has a positive charge, but there's more positive charge inside the cell than outside (due to potassium), therefore, Na+ goes extracellular (out)
The concentration gradient considers that the ion will go from the most concentrated to at least concentrated by passive diffusion so no trans-membrane proteins in the game attention.Na + is very concentrated in extracellular and few intracellular, therefore, it tends to go intracellular (in).</span>

Jet lag occurs when a person moves rapidly from one time zone to another, causing conflict between the body's biological rhythm
vova2212 [387]

Answer:

c) melatonin

Explanation:

Melatonin its a hormone formed by the pineal gland, which regulates an individual wake cycles and sleep. Jetlag alters the hormone function leading to an alteration with the body clock of the persom.

Jetlag is a sleep disorder common to those who travel swiftly over several time zones. It is not a permanent sleep disorder. Its due to the body's internal clock lacking sync with cues generated in a different time zone, Cues may be due to light exposure and how often the person eats.

A basic factor on ones internal clock is sunlight. It controls the regulation of melatonin which aid in synchronizing cells in the body.

Specific cells of the tissue at retina moves the light signals the thypothalamus.

At night, the hypothalamus signal to the pineal gland to produce melatonin. At daylight hours, the reverse is the case.

What is the best evidence for a three-domain system?
ch4aika [34]

Answer:

The best evidence for the three domain system is

Sensitivity to Antibiotics

Explanation:

The three domains of life includes :

Archaea - oldest known domain, ancient forms of bacteria.

Bacteria - all other bacteria that are not included in the Archaea domain.

Eukarya - all the organisms that are eukaryotic or contain membrane-bound organelles and nuclei.

Types of evidences for the three domain system are:

1) differences in the sequences of nucleotides in the cell's robosomal RNAs (rRNA)

2) the cells's membrane lipid structure.

3) its sensitivity to antibiotics.

Wes places red blood cells in a petri dish with pure water and observes them under a microscope. He drew a model to illustrate h
lys-0071 [83]

The correct answer is: D. The red blood cells were placed in a hypotonic solution. Water moved from the outside of the cells to the inside of the cells until the cells burst.

Hypotonic solution can be described as solution that has less solute and more water (H2O) than another solution. In order to maintain homeostasis, the water will move (via osmosis) into the cell, through the semipermeable membrane of the red blood cell.

Levart [38]
I'm not sure how you compute the density of agcl using the length of a unit cell edge measure of 555 pm.

But as per online research, the density of AgCl is 5.56 g/cm³

AgCl is the chemical formula of silver chloride. It<span> is easily synthesized by combining aqueous solutions of silver nitrate and sodium chloride.

How do structures in living organisms compare with structures of nonliving things such as construction cranes, buildings, ships,
hjlf
For the answer to the question above, there is no such thing as a non-living organism. Because organisms are only a term for living things.

1. Cellular structure: all living organisms generally have a cellular structure i.e., they are made up of one or more cells. 
<span>The protoplasm is the physical basis of life. </span>

<span>There is no such fundamental and structural unit called cell in non-living things. </span>

<span>2. metabolism : The various life processes taking place within the body of an organism is collectively termed metabolism. The metabolic processes can occur only in living organisms and not in nonliving things. </span>

<span>3. growth, repair and death : Growth consists of the living organism absorbing materials entirely different from those that make up its body and convert them into body building substances. Growth in non-living substances such as crystal is at the cost of material similar to that of which it consists. Same substance is added without conversion. </span>
<span>The growth is permanent, irreversible process in living organisms but can be reversed in non-living things. </span>
<span>Growth is different in different parts of the body of an organism. Growth is uniform throughout in the non-living things. </span>

<span>Respiration, nutrition,excretion, movement,irritability, reproduction, life span, death, evolvability are other properties of a living organism.</span>
