Answer:
water splash that is carbon dioxide
Explanation: water drip splash
OPTIONS:
a. Water from the late was not tested for other possible pathogens b. Residents of other nearby towns were not tested for the bacteria c. The residents' genetic predisposition for getting ill was not determined d. Other sources of drinking water were not tested for bacteria
Answer:
d. Other sources of drinking water were not tested for bacteria
Explanation:
The source of error in the experimental design of the students stems from the failure to collect samples from other sources of the town's drinking water. The samples collected and tested were simply unrepresentative of the drinking water supply of the town, as the samples collected only represented water from the lake, which is 80% of the town's supplies of drinking water.
To arrive at a good conclusion, samples collected should represent adequately, all sources of drinking water of the town, rather than just representing supply from mainly the lake, which accounts for 80%.
It could be that the source of bacterial infection might emanate from other sources of drinking water that was not represented in the samples collected for testing.
The water molecule has the ability to form hydrogen bonds, between atoms of oxygen and hydrogen of different molecules (they can also be formed between atoms of hydrogen, phosphorus, and nitrogen, but in the case of water we refer only to hydrogen and oxygen). When this phenomenon occurs between molecules of the same species (one molecule of H2O with another molecule of H2O), it is called cohesion, which is the attraction that molecules have for others of the same type. In the case of water, cohesion occurs thanks to hydrogen bonds, and this union is very strong and difficult to break.
Plants utilize carbon dioxide in a method identified as photosynthesis. During photosynthesis, plants yield off oxygen as a decay product. Carbon dioxide passes from the atmosphere into the needles of plants by tiny holes in the plant's leaves.
Both Oxygen cycle and carbon cycle acts independently but are subordinate on each other because the carbon cycle provides off oxygen for the oxygen cycle to use, and in return, the oxygen cycle releases carbon dioxide (CO2) which goes back into the carbon cycle. Plants are the principal vehicle by which the oxygen and carbon cycles are correlated.
Answer:
Microtubules.
Explanation:
The main cytoskeleton of the cell is micro tubules, micro filaments and intermediate filaments. This structure helps to provide the stability and maintains the cell shape.
Microtubules are made of the polymers of tubulin. The microtubules are hollow shape like protein that forms the main part of the cyoskeleton. The microtubules maintains the cell shape and allows the movement of the cellular organelles of the cell.
Thus, the correct answer is microtubules.
