C. It requires active transport because the use of energy is necessary, the natural and opposite flow to this, would be from high to low concentration that requires little to no energy (i.e passive diffusion).
Answer:
Bacteriophage
Explanation:
A bacteriophage, also known informally as a phage, is a virus that infects and replicates within bacteria and archaea. The term was derived from "bacteria" and the Greek φαγεῖν, meaning "to devour". Bacteriophages are composed of proteins that encapsulate a DNA or RNA genome, and may have structures that are either simple or elaborate
Answer:
For any experiment we can say that light waves are the electromagnetic waves because they make up what is known as the electromagnetic spectrum.
Explanation:
- Light is the moving energy form that is made up of tiny particles known as photons.
- The light waves comprises of both magnetic and electric aspects hence known as electromagnetic.
- The process of propagation of light wave is : the fields vibrates perpendicularly in the same direction of propagation of the wave, and at 90 degree angle with each other.
- Similar to sound waves, light wave can interfere with each other.
Answer: nucleus
Explanation
The nucleus is not the only source of DNA, besides it, DNA is also found in the mitochondria of all eukaryotic cells, as well as in the chloroplasts of plant cells and such DNA is called extrachromosomal DNA.
The DNA from the mitochondria (mtDNA) and chloroplasts are small and circular, which are similar to the prokaryotic DNA.
mtDNA contains its own genes that encode proteins that are part of the electron transport chain.
