Generally describe what forces ultimately shaped the earth into its modern form

1 answer:

8 0

The force of gravity is a major force that created the earth. As rocks and ice clumped together as they spun around the newly formed star (sun), the force of gravitational pull increased and attracted more debris (rocks and ice). The clumps of rocks, debris, and ice, therefore, grew into a planet.

Another is electromagnetic force. The spinning currents in the outer core of the earth create a dynamo effect that forms a magnetic field around the earth. This shields the earth from the solar storms of the sun hence protects life and the atmosphere.

Weak nuclear force is responsible for maintaining the heat of the earth’s interior which is critical for maintaining the dynamo effect of the outer core so the earth is protected by its magnetic field.

yulyashka [42]

Answer:

B. The mutation results in a new, dominant allele

C. The mutation occurs in a gene that controls development and alters differentiation of a cell type during development.

D. The mutation occurs in a codon and alters the function of the final protein

Explanation:

All the above things will change the ultimate expression or phenotype by altering the proteins. Choices B, C, and D will all change the outer functioning.

Choice A only affects the rate of transcription, so it may go faster or slower, but the end product will be the same.

This part that doesn't look like it's one of the choices ("The mutation occurs in a portion of an intron not responsible for exon splicing.") would not affect phenotype, because introns are removed before the RNA is sent out.

Choice E says that the amino acid sequence is unchanged, meaning the protein final product will be the same and the expression will not change.

Which molecule could he make that consists of long chains of red and black colored balls

Phoenix [80]

Answer:

He could make a macromolecule which is made up of carbon and hydrogen only.

Explanation:

An atom a fundamental piece of matter that constitutes a chemical element.

A molecule is a group of atoms bonded together. It represents the smallest fundamental unit of a chemical compound that can participate in a chemical reaction.

The red balls denote the hydrogen and black balls denote the carbon. He could make a macromolecule which is made up of carbon and hydrogen only.
