Answer:
9
Explanation:
Any pH value above 7.0 is that of a base. Below that value is the pH of an acid.
The environmental change that is caused by the increasing levels of solar energy will cause the melting of the ice at the poles and hence increase the sea level, whereas, the movement of tectonic plates under the surface of Earth causes the drifting of the continents. We have surely come across the formation of new islands, mountains and vanishing of existing land masses due to the movement of tectonic plates in the past.
Hence the continent drifting is caused by the movement of tectonic plates. This is definitely a long-term change since the time period taken for such geological changes is large.
Hence the option B applies to our answer
About 2/3 of all body fluid is within cells and intracellular compartments. <span>Body fluids (or biofluids) are This is divided between intracellular fluid (ICF) and extracellular fluid (ECF) in a 2 : 1 ratio. Intracellular fluid is within cells and intracellular compartments, while extracellular includes the interstitial fluid (between cells) and the vascular fluid (blood).</span>
False because temperature is what measures the average kinetic energy in an object.
The answer is -Prokaryotic cells have single strands of DNA, and eukaryotic cells have multiple chromosomes.
The main difference between prokaryotic and eukaryotic cells is that eukaryotic cells have long tangled strands of DNA packed in the nucleus, and prokaryotic do not have nucleus and their DNA is short stranded. Since DNA strand are very long in eukaryotic cells, they are organised in chromosomes. The number of chromosomes is different for each species, and 23 chromosomes are characteristic for humans.
