Answer is Carbon and Oxygen cycles
The oxygen cycle and carbon cycle are two biogeochemical cycles which depends on photosynthesis process.
Photosynthesis is a process in which green plants capture and use sunlight as source of energy for the synthesis of carbohydrate (food) from carbon dioxide and water. During photosynthesis oxygen is released as a by-product.
The oxygen released during photosynthesis is used in cellular respiration. During cellular respiration, carbon dioxide is released which is used in photosynthesis. Thus, oxygen cycle and carbon cycle depends on photosynthesis process.
Answer:
The waves erode seashells and rocks on the shore into small granuels called sand.
Explanation:
The answer is permissiveness.
Thyroid hormone exerts a significant effect on the ability of the smooth muscle cells in bronchioles to respond to other hormones, especially catecholamines (including epinephrine). Thyroid hormone binds to the receptors on the surface of the cells and allow more receptors to accept epinephrine, which in turn, allows <span>bronchodilation</span>.
Answer: Option B.
Polar covalent bonding.
Explanation:
Hydrogen bonding or polar covalent bonding exist between water molecules. Water have one oxygen molecules that is electronegative and two hydrogen molecules that is slightly electropositive. Two hydrogen atoms are covalently bonded to one oxygen atom. In covalent bonding, there is sharing of electrons between atoms. In water, there is unequal sharing of electron between oxygen atom and hydrogen atoms. Oxygen atom tend to attract more electrons that hydrogen atoms, which make water a polar molecule.
