What layer of earth are they in?
Lithosphere
What are they floating on?
The asthenosphere (the weaker upper mantle)
What makes them move?
The intense heat from the earths core that causes molten rock in the mantle layer to move. It moves in a pattern called convection cells that forms when warm material rises, falls, and sinks down.
Curd as it is the thickest substance to stop something from passing
Answer: The concentration of salt is high and lacks hydration.
Explanation: A cell must stay in homeostasis cellularly if the cell has shrunk its salt is too high and needs hydration.
<span>They are both sites of new cell formation. This is the character both have in common.Bone marrow is the site of formation of most cells of blood like RBC, WBC, Lymphocites etc. Epidermis is the outermost layer of skin which consists of dermis beneath. Epidermis on destruction produces new cells</span>
The hatchery bred salmons do have different traits as compared to the wild salmons because of the environmental effects it does have on their maturity.
Option B.
<h3><u>Explanation:</u></h3>
The wild varieties of salmons do live in natural streams and rivers and do have to collect their own food themselves. They face the struggle for their existence as well as they have to compete with each other for getting food. So their adaptation is very high and specialized.
Whereas the hatchery bred salmons get their food from what is supplied to them. They get perfect conditions for living artificially. They also doesn't face wild traits of diseases which do often attack the wild varieties, so lacks the immunities against them. Thus these differences lead to the different traits between them. Thus they cannot survive together and it will lead to a divergent evolution, or the survival of the fittest and natural selection will eliminate the hatchery bred varieties because if their incapabilities.
