the skin on your body
Explanation:
because it is a tough cover it protects the body in many ways,thus it's water proof.
Answer:
At 0hr it was 200 bacteria
At 1 hr it doubled and was 400
Means: at every 1 hr the population of the bacteria doubles
400 bacteria = 1hr
2000 bacteria = X
X = 2000 × 1 / 400
X = 5 hrs
The structures of chloroplast and mitochondria are similar. Both organelles consist of a smooth outer membrane, folded inner membrane (in chloroplasts called lamellae, in mitochondria called cristae), and fluid intracellular space (in chloroplast called stroma, in mitochondria called matrix). Only these structures allow those organelles to perform their function. The presence of folded inner membranes enables a formation of compartments inside the organelles. Differences in concentrations of hydrogen ions in those compartments are important for photosynthesis in chloroplasts and cellular respiration in mitochondria.
