Answer:
Plant cells have cell walls, constructed outside the cell membrane and composed of cellulose, hemicelluloses, and pectin, a cell membrane similar to that of the animal cell, a large central vacuole, a water-filled volume enclosed by a membrane known as the tonoplast, they contain plastids, the most notable being chloroplasts, which contain the green-colored pigment chlorophyll that converts the energy of sunlight into chemical energy, and then all the other organelles of the animal cell (mitochondria, endoplasmic reticulum, nucleus and nucleolus, golgi apparatus, etc.)
Limestone contains calcium carbonate which comes from animals that have shells, it already has carbon. Other sources are ocean animals which create shells that combine both carbon and calcium. Their dead bodies also release carbon to the ocean. Limestone is also known as a sedimentary rock that has carbon. Outside the ocean, limestone emits the carbon and becomes part of the carbon cycle. In addition to this, limestones are widely used by people becomes a part of the carbon cycle. Its component is present on asphalt, animal feed.
Answer:

Exocytosis is the reverse of endocytosis. <em><u>Quatities of material are expelled from the cell without ever passing through the membrane as individual molecules.</u></em> By using the processes of endocytosis and exocytosis, some specialized types of cells move large amounts of bulk material into and out of themselves.
Answer:
A) results in evolutionary adaptation
Explanation:
Natural selection is the process in which organism with specific traits are able to survive than others. Natural selection allows the fittest to survive while eliminating the others. It prepares the species for environmental changes by resulting in evolutionary adaptation.
Evolutionary adaptation occurs when species goes through certain processes (hereditary, habits, Physical structures) to become fit in environment. These changes help the organism to evolve to adopt the changing environmental conditions.
Example; Sweating in human.
