Protein, starch or natural rubber are polymers synthesized by living things.
The answer would be transitional forms like Archaeopteryx make
available DNA confirmation that demonstrates how organisms are related. Transitional
fossils establish the middle forms that happened over the evolutionary
trail taken by a single genus. A case in point of a transitional fossil is
archaeopteryx, which relates the evolution of dinosaurs (from jaws and claws)
to birds (feathers).
Answer:
cell wall
chloroplasts
central vacuole
Explanation:
The plant cell has a cell wall, chloroplasts, plastids, and a central vacuole—structures not found in animal cells. Plant cells do not have lysosomes or centrosomes.
Explanation:
What happens during daytime is, oxygen that gets trapped between filaments of algae, moves them to the surface and during night as O2 is not produced, they slowly sink to lower depths, and you don't see them
Answer:
The answer to your question is: Active transportation
Explanation:
Cell can move molecules in or out of it by two processes: Active or Passive transport.
Active transport: is the movement of molecules against a concentration gradient. Use proteins or enzymes to happen.
Passive transport: is the movement of molecules or ions from a higher concentration to a lower concentration.
