Answer:
C. Repolarization would occur, but much more slowly.
Explanation:
Repolarization is the change in membrane potential that returns it to a negative value just after the depolarization phase of an action potential has changed the membrane potential to a positive value. Sodium channels slow down this process.
When a single celled paramedic is placed in a hypotonic solution, the cell swells and then bursts.
<h3><u>
Explanation:</u></h3>
Hypotonic solutions are the solutions that contain more water than present in a cell. Hence, when an animal cell is placed in a hypotonic solution, the cell will undergo osmosis. Osmosis is the movement of any form of solvent through a plasma membrane to a higher concentration from a lower concentration until the the external concentration matches the inner one.
To put it in simple words, when a single animal cell is places in a solution which has more water than other solutes, the water will invade the cell until it can accumulate the amount that equalizes the inner and external concentration. The cell will begin to swell up until there is no more space and finally, it will burst. For example, when you put water on a cloth that has blood stain on it, the cells will burst and make the stain worse than before.
Answer: reptiles are ectothermic , while Amphibians are endothermic
Explanation:reptiles and Amphibians are vertebrate.reptiles are a group of air breathing vertebrates that have internal fertilization and scaly bodies.some difference between Amphibians and reptiles include
1)the presence of dried scale in reptiles to prevent water loss.in Amphibians, their skin is smooth and moist and without scale
2)reptiles have more powerful jaws
3) internal fertilization is in reptiles while fertilization is usually external in Amphibians
4)the Amphibians respire by gills, lungs , mouth or through their most skin but reptiles respire through the lungs.
But Reptiles are ectothermal and so are Amphibians
They are both terrestrial and aquatic organisms.they both have separate sexes.
Examples of Amphibians are salamander and frog.example of reptile are turtle and alligator
Answer:
The correct answer is - option D. a pen.
Explanation:
A triple beam balance is an instrument which is a type of lever used to measure the mass of an unknown mass object very precisely. This instrument shows a very small error of ±0.05 grams.
It has a measurement tray on one side of the instrument and a fulcrum on the other side. On the measurement tray, an object with an unknown mass is placed and a set of sliding weights on the fulcrum. The sliding weights called riders that slide on beams to balance the object. The maximum weight a triple beam balance can measure is 610 grams ( 10+500+100).
Thus, the correct answer among these options is - option D.a pen.
