The situation would be that, in a sealed tube, there are 3 to 4 nails inside and a certain amount of calcium chloride was added. After three days, there will be no changes to be observed in the first tube since the oxygen is not enough to initiate a change and there is no presence of water. For the second test, the same situation is made but boiling water was filled in the tube. For this, no changes would still be observed since there is no moisture. For the last test, the same situation as the first but it is filled halfway with water. After 3 days, rust would be observed on the nails. In order for rust to happen, there should be water and oxygen. The oxygen in the early atmosphere of the Earth would react with iron present in the oceans thus producing iron ores.
Answer:
<u>Perilymph</u> is a fluid similar to cerebrospinal fluid that fills the space between the bony labyrinth and the membranous labyrinth.
Explanation:
The inner ear consists of the bony labyrinth and the membranous labyrinth, it is filled of endophilia and surrounded by perinfilia (the bony labyrinth surrounds the membranous, between both there is a space occupied by the perilymph). Perilymph is an albuminous fluid that has an ionic composition similar to the extracellular environment, it bathes the tympanic and vestibular ramps, fully occupying the bony cavities of the inner ear, bathing the membranous parts located inside these cavities.
Answer:
The correct answer is- facilitated diffusion
Explanation:
In facilitated diffusion molecules(solutes) are moved from area having a high concentration of solute towards the area having low solute concentration through a semipermeable membrane with the help of specific proteins is called facilitated diffusion.
As molecules move along the concentration gradients so no energy consumption is required in facilitated diffusion. Transport proteins like channel proteins are used to transport the molecules across the cell.
The rate of transport is higher in facilitated diffusion than simple diffusion. Polar and charged molecules can be diffused by facilitated diffusion.
Mitosis never stops in most of the cells of our body like "Gastrointestinal tract", "that give rise to blood cells" etc.
But, it stops after the death of the body.
Hope this helps!
