Answer:
Option B, Barr graph
Explanation:
A bar graph is used for comparing several items all together based on any certain parameter.
Here, the lead content is the comparison parameter while the six sample of contaminated water wells acts as different items being compared.
A line graph is good to show a continous varying data set, while a circle graph is good to represent the component constitution of any major substance and a data table is best to represent a data set with multiple attributes.
Hence, option B is correct
Answer: The correct answer for the fill in the blank is Asexually.
Asexually reproducing organisms have rapid rate of reproduction as only a single parent is involved in this. Also, there is no formation and fusion of gametes in this mode of reproduction.
They produce larger number of offsprings through rapid rate of reproduction. By doing so they have larger chances of survival.
For instance, if a part of bacterial species population is wiped out through viral infection, bacteria can compensate this loss by the rapid rate of reproduction. This increases their chances of survival.
Answer: Photosynthesis removes carbon dioxide from the atmosphere and releases oxygen, Respiration takes oxygen in and releases carbon dioxide, decomposition releases carbon dioxide back into the air from dead animals or waste, Burning is the same
Explanation:
Answer:
The correct option is the pKa of acetic acid or acetate.
Explanation:
The blood pH is affected by hyperventilation since it triggers hypercapnia, an increase in metabolic acids and therefore a decrease in blood pH.
Excessive consumption of sodium bicarbonate, since this would alkalize the blood, and finally, prolonged fasting or excessive hunger generates the degradation of fat sources, with the consequent formation of ketone bodies as a product, and therefore entering a metabolic acidosis.
Answer & Explanation:
All archeas are single-celled organisms, and despite having prokaryotic cells, there are both similarities and differences between archaea and bacterial cells and also with eukaryotes.
Archaea have only one cell that has no nucleus or real organelles, and its cells have membranes composed of branched lipids, which greatly alter the structure of the archaeal cell membranes. In addition, the archaea have only one DNA strand (uniqueness).
Animal cells differ from archeas because they are multicellular (organisms with several cells), each one having a nucleus, and they also have specialized organelles.
In addition, animal cells have compounds called phospholipids in their membranes, which are unbranched lipids, and therefore do not cause major changes in the structures of their cells. Finally, animal cells have double-stranded DNA (complementary duplication).
