Answer:
0.25m/hr
Explanation:
The average speed of an object is the total distance travelled divided by the total time taken.
0.5m/2hr = 0.25m/hr
Well, the cell membrane is full of a bunch of little holes. Sort of like a coffee filter.
What does a coffee filter do? Well, you put the coffee in it and run water through it. Then what?
The water is small enough to pass through the filter and bring some of the coffee with it. But the coffee grains are too big to pass through the filter. If we really wanted the coffee grains to get through the filter, we could force them through. Do you want chunks in your coffee? Eww.
Now the cell membrane is the same way, the little things (water, carbon dioxide, oxygen, sugar) are all small enough to fit through the tiny holes in the cell membrane. This is called, "Passive Transport". Because the things can passively float their way in and out of the cell.
Now some other things are too big to fit through, so to make them fit, the cell has to use energy to open itself a little bit more to let them in. This is called, "Active Transport". Because the cell needs to be active and use energy to let those things in.
<span>Now Osmosis is the transfer of water and salts (basically) throughout the cell.
Both Salt and Water are small enough to fit through the Cell Membrane using "Passive Transport".
I've posted this same response earlier, and it is my writing.</span>
Answer:
The trade winds or easterlies are the permanent east-to-west prevailing winds that flow in the Earth's equatorial region (between 30°N and 30°S latitudes).
Explanation:
In the event that people with the new phenotype are more fit than the dim or dark mice, the white allele may increment in recurrence in the populace. Dark mice will probably keep on being more typical than alternate phenotypes.
The phenotype is the shade of their hide and for this situation, the greater part of the posterity will have dark hide, since they are altogether half breed and dark hide is prevailing. The greater part of their posterity will convey the attribute for white hide, yet it won't appear on the other side.
The correct answers are -
b) Homeostasis
c) Immunity
e) reproduction
f) growth and development
Reason -
The endocrine system (produces and secretes hormones) is a vital system as it regulates the homeostasis by regulating the cell activity in the body. The endocrine system releases relevant hormones during specific time period in the blood which are then transported across the blood , this not only maintains the chemical physical balance in our body but also regulate the vital functions of body such as growth, reproduction, and immunity
