Answer:
A Remora fish would attach itself to a shark and use the shark for transportation and eat all the food that is left over from the shark. The symbiosis relationship between them is a commensalism relationship because the remora is getting its food and the shark gets no benefit.
<span>Water has a pH of 7. If it was 0, it would be a strong acidic acid
Water can dissolve most substances due to its polarity and hydrogen bonds
Water can dissolve minerals due to it polarity and hydrogen bonds
Water expands when it freezes because it it able to create my tetrahedron structures in solid form and this structures are broken and it melts
When water infiltrates something it seeps into the ground and becomes part of the water table.

Answer:
<u>frictional</u>
Explanation:
This scenario follows Newton's third law of motion which alludes to the fact that for every force or action exerted by a person on a body there is an equal and opposite reaction exerted back.
Because there is a limited frictional force (a force exerted by an object when an object moves across it) between
- the canoe and
- water surface (the opposite force/reaction)
Here, the paddle helps the boatman apply a force on the water, resulting in the opposite amount of force been sent back; pushing the boat forward.
Answer:
Habituation.
Explanation:
Learning may be defined as the process of change in the behavior of the organism by the result of its experience. Two main types of learning are innate learning and acquired learning.
Habituation may be defined as a type of the non associative learning in which the innate stimulus may get decrease after its repetition. The response of the new born can against the visual memory can be created by taking some picture as stimulus and repeat this stimulus again and again.
Thus, the answer is habituation.
Answer: Respiratory gases(Oxygen)
Explanation:
The essential role of cadio vascular system is to supply blood; containig metabolites (glucose,amino acid, fatty acid and glycerol) and gases expecially Oxygen,needed for combustion of these nutrients(metabolites) in mitochondrial of cells (cellular Respiration) to generate ATPs for biochemical activities of the body.
