Answer: Mitochondria and Chloroplast have double membrane(inner and outer) but golgi apparatus and endoplasmic recticulum have single membrane.
Explanation:
Mitochondria is referred to the power house of the cell where energy is produced.
Chloroplast is the organelle found in green plants use for photosynthesis to produce energy. Both chloroplast and mitochondria are found in multicellular organisms and their function is to produce energy. The both have double membrane bound organelles.
Golgi apparatus and endoplasmic reticulum are single membrane bound organelles and they are found in eukaryotic cells. The endoplasmic recticulum transport synthesized protein to vesicles of Golgi apparatus.
Emperor penguins need lungs to breathe. In penguin lungs, air never stops. ... Once the air goes farther into the trachea it splits into two different directions into both lungs. To get the oxygen into the blood cells, it must come "within small distance of the penguin blood cells".
Answer:
Melanin is responsible for black colour of hair.
Explanation:
Hair is black in colour because it is determined by the amount of a pigment present in hair is called melanin. If eumelanin which is a type of melanin, present in hair, it gives people black or brown hair. If the receptor is not activated or is blocked in the hair, then melanocytes make pheomelanin instead of eumelanin and then the black or brown hair colour did not occurs so we can conclude that melanin is responsible for black colour of hair.
Answer: population density
Explanation:The number of individuals living within that specific location determines the population density.
It is the fluid that suspends all the organells, and protects them from damage. It's also known (I think) as cytoplasm
