Answer:
Cell membrane present, ribosome present, lysosomes present, nuclear membrane present: Animals
Cell wall present, ribosomes present, nuclear membrane absent: Prokaryotic
Cell wall present, ribosome present, nucleus present, large vacuole present: Plants
Reproduces inside a cell, Nucleus absent, RNA present : Virus
Explanation:
Animals are multicellular organisms which do not possess cell wall. Hence option 1 represent animals.
Prokaryotes have cell wall but lack nuclear membrane. Hence, option 2 represents prokaryotes.
Plant cells have a cell wall, a nuclear membrane as well as a large nucleus. Hence option 3 is plants.
The plasma membrane of a cell is selectively permeable, which means it allows some materials to pass.
Answer: C) or the third option.
Answer:
controlled experiments ( third choice)
Answer: Hope this helps
GAS EXCHANGE: the intake of Oxygen and the expulsion of Carbon dioxide. In the capillaries of the alveoli, oxygen travels due to the concentration gradient into those capillaries. Carbon dioxide is then expelled from those capillaries.
RESPIRATORY MEDIUM: is air for animals and water for fish. It is basically the substance through with living animals receive their oxygen.
RESPIRATORY SURFACE: is where the gaseous exchange takes place. The oxygen and carbon dioxide move across the respiratory surface entirely by diffusion.
