The oceanic crust is denser than the continental crust.

Also, the oceanic crust consists mostly of basalt.

What is the oceanic crust made of?

The topmost layer of the tectonic plates' oceanic part is called the oceanic crust. It is made up of two oceanic crusts: the upper crust, which contains pillow lavas, and the bottom crust, which is made up of troctolite, and ultramafic cumulates. The crust sits on top of the hard mantle's topmost layer.

Dark-colored rocks named basalt and gabbro make up the majority of the marine crust. It is lighter-colored rocks called andesite and granite that make up the continental crust, which is thinner and denser. Because of its low density, continental crust "floats" high above the viscous mantle, generating dry land. It develops as magma rises to fill the space between divergent tectonic plates and is consumed in subduction zones.

How can a mutation led to variation

Vikki [24]

Mutations produce random changes in an organism's genetic code. Mutations can occur in non-reproductive cells and then they will not be passed to the next generation, therefore will not contribute to variation. Only mutations that occur in reproductive cells are passed on to the next generations and contribute to genetic variation in a population.

The cell membrane is comprised of a phospholipid bilayer that remains interspersed with protein molecules.
Each phospholipid molecule is comprised of:

A glycerol molecule linked with the help of ester bonds to,
one phosphate group,
two fatty acid (saturated or unsaturated) molecules.

Being hydrophilic in nature, the phosphate group faces outside the lipid bilayer forming hydrogen bonds with the water molecules.

Being hydrophobic in nature, the fatty acid molecules faces to the interior of the bilayer avoiding contact with water and forming hydrophobic interactions with each other.
The saturated fatty acid molecules have a straight hydrocarbon chain as they lack any double bonds. However, the unsaturated fatty acid molecules possess multiple double bonds that generate a kink or bent in their structure. The kink causes the molecules to occupy more space in the bilayer and also help these molecules to move laterally about their position, thereby generating fluidity in the membrane.
The lateral movement of the lipid molecules also causes the lateral movement in the interspersed protein molecules.
The interspersed protein molecules has various functions like, they act as channel proteins, carrier proteins, receptor proteins, etc.

Please hurry!

Reptile [31]

Answer:

the grass is the producer, the snake is the secondary consumer, and the eagle (i think thats what the bird is) is the tertiary consumer

Explanation:

the grass is being produced so that one is obvious

the snake is the secondary consumer because it eats the bunny and the bunny consumes the grass. So the secondary has to be the snake

the eagle is the tertiary consumer because it eats the snake and like i stated before the bunny consumes the grass, then the bunny gets consumed by the snake, but the the snake gets consumed by the eagle.

hopefully this was helpful
