Hello There!

Oxygen compromises about 47 percent by weight of earth's continental crust.
Another important element is silicon.
Continental crusts are older and less dense when compared to the oceanic crust.

Hope This Helps You!

What causes over growth in humans
prohojiy [21]

Does your child seem much shorter - or much taller - than other kids his or her age? It could be normal. Some children may be small for their age but still be developing normally. Some children are short or tall because their parents are.

But some children have growth disorders. Growth disorders are problems that prevent children from developing normal height, weight, sexual maturity or other features.

Very slow or very fast growth can sometimes signal a gland problem or disease.

The pituitary gland makes growth hormone, which stimulates the growth of bone and other tissues. Children who have too little of it may be very short. Treatment with growth hormone can stimulate growth.

People can also have too much growth hormone. Usually the cause is a pituitary gland tumor, which is not cancer. Too much growth hormone can cause gigantism in children, where their bones and their body grow too much. In adults, it can cause acromegaly, which makes the hands, feet and face larger than normal. Possible treatments include surgery to remove the tumor, medicines, and radiation therapy.

Difference between osmosis, diffusion and plasmolysis
pickupchik [31]
Osmosis is the movement of water particles from an area of high concentration of water particles to an area of low concentration of water particles across a semi permeable membrane

Diffusion is the movement of particles from an area of high concentration of particles to an area of low concentration of particles across a partially permeable membrane

Plasmolysis is the shrinking of the cytoplasm if a plant cell in response to diffusion of water out of the cell and into a high salt concentration solution as the cell membrane would pull away from the cell wall

Why are dominant alleles not necessarily more common than recessive alleles?
marta [7]
It all depends on the trait. If the dominant is more common that the recessive trait then it is more likely to a dominant trait in the gene pool. But if the recessive trait is more common in the gene pool then you will have a recessive trait. Does this make sense? Let me know if I'm right!
