There are trillions of cells EVERYWHERE including blood cells, brain cells, and even skin cells !! I believe that multicellular organisms that are large need to have trillions of cells to be able to fill their whole body. For example , humans, Humans have one of the most complex cells, we humans are very big so thousands of cells would not be enough to contain our entire body. Even the word ' multicellular' meaning multiple cells gives people a hint that we are multicellular . In conclusion , trillions of cells are needed for multicellular organisms , without them we wouldn't be able to function properly.
Temperature affects the plants because if its too cold a plant would not grow.
Answer:
One of the characteristic feature of the phospholipid bi- layer is that like dissolve likes.Therefore,polar molecules and compounds pass though the hydrophllic heads,while non-polar lipid soluble substances pass through the hydrophobic tail,but can not diffuse across the head.
The plasma membrane is amphipathic.It is made up of the hydrophilic heads and hydrophobic tails
Cortisol is made of lipid.Therefore,it will diffuse easily across the bi layer of the plasma membrane though the tail,while LH and Epinephrine,will not diffuse across this hydrophobic barriers,since they are made up of polar molecules.
Explanation:
<span>Although the area Ardi was found it is now desert, but that doesn't mean it was always like that. Scientist discovered fossilized wood and seeds in the same sediment layer as Ardi leading them to believe that Ardi's environment was a woodland habitat.</span>
