Answer;

Evolution

Mutations such as polyploidy and crossing over provide the genetic basis for evolution.

Explanation;

Evolution is the change in the characteristics or traits of a species over several generations and relies on the process of natural selection.

It occurs when some individuals or some alleles (alternative form of gene) reproduce themselves more than others,increasing their prevalence in subsequent generation.

Polypoidy and crossover brings about mutations that cause changes in characteristics and traits over time resulting to evolution.

Match each light behavior with its definition.
aalyn [17]

1-refraction

2-transmission

3-reflection

4-diffraction

<u>Explanation:</u>

Refraction is the bending of a wave when it enters a medium where its speed is different.Refraction is responsible for image formation by lenses and the eye.

Transmission of light is the moving of electromagnetic waves through a material. This transmission can be reduced, or stopped, when light is reflected off the surface or absorbed by the molecules in the material.

Reflection is when light bounces off an object.Light is reflected when there is a mismatch between materials through which the light is travelling.

Diffraction is the slight bending of light. The amount of bending depends on the relative size of the wavelength of light to the size of the opening.

All living things contain carbon.which of the following statements is true about carbon atoms?
vfiekz [6]

I. Each carbon atom can form single bonds with up to four other carbon atoms. II. Each carbon atom can form double bonds with up to two other carbon atoms. III. Carbon atoms can join together to form chains or rings. IV. A single molecule of some compounds can contain thousands of carbon atoms.

Answer:

All the given choices

Explanation:

Carbon is a very interesting element which is the backbone of most organic compounds.

Organic compounds are made up of carbon. Carbon forms a wide range of compound due to the following properties;

  • An atom of carbon has 4 valence electrons and can bond with 4 other carbon.
  • Carbon can form single, double and triple covalent bonds.
  • They can join together to form rings or chains.

3. Name the molecule that would be destroyed (denatured) within the membrane at 70°C
egoroff_w [7]

Answer:

The correct answer is - Protein molecule.

Explanation:

The cell membrane is the outer membrane of the cell that differentiates the external environment from the internal components of the cell. The cell membrane is made up of two major components that are lipids and proteins.

Proteins are present as channels and in the form of membrane proteins in between the lipid bilayer. Protein is the molecule that denatured or destroyed at high temperatures such as 70 degrees.
