Answer: Option B) have mitochondria and chloroplasts.
Plant cells have mitochondria and chloroplasts.
Explanation:
Unlike animal cells, plants cells possess mitochondria and chloroplasts. Mitochondria serves as site for respiration giving off oxygen as by-product while chloroplasts are site of photosynthesis, where sugar molecules are formed from simple inorganic molecules like atmospheric carbon dioxide, water and sunlight trapped by chlorophyll.
Answer: osmosis
Explanation: osmosis is the movement of the water molecules from a region of high concentration of solute to a region of low concentration of solute, through a semi-permeable membrane.
This movement occurs until the concentration on both sides is on equilibrium.
Semi permeable membrane allows the movement of water only but not the solute.
In this case,water moves from region A to region B.
Answer: yes they are renewable.
Explanation:
Trees are a natural resource that can be renewed by (the planting of trees) replacing the trees that are harvested for use by people. We depend on forest products for things like the wood we burn for heat and the wood we use to make houses and furniture. We use trees for the paper to make books and letters we write. Actually, there are more than 5,000 things made from trees. Trees give us baseball bats, shoe polish, and even tooth paste that comes from tree extracts.
