The statement that would best explain why one red blood cell hemolyzes more quickly than another is if the cell that hemolyzes more quickly acquires NaCl at a faster rate.
Water moves by osmosis in and out of cells from the region of high water potential or low solute concentration to the region of low water potential or high solute concentration.
A cell with a higher solute concentration than the surrounding solution will keep acquiring water from its surrounding until the cell becomes turgid and bursts or lyses due to over-turgidity.
If the reverse occurs, such a cell will lose water and become flaccid.
Thus, if a red blood cell acquires NaCl, a solute, at a faster rate, such a cell will also acquire water and become turgid/lyses at a faster rate.

Answer:
Stephen is not his biological father.
Explanation:
DNA fingerprinting is a technique use to determine the DNA sequence of an individual organism. Short tandem repeats are unique among the individuals ans used to identify the individual in population.
The George DNA fingerprinting shows that he has STRs length of 6 and 7. Stephen's STRs does not match with his son George whereas Mary shows some similarities with George STRs. This indicates that Stephen is not the biological father of George because the biological father's STRs must match with the children STRs.
Thus, the correct answer is option (a).
Answer:
b. B antigens
Explanation:
Based on the information provided within the question it can be said that Antibodies against B antigens would be present in Jess' blood. This can be seen in the chart attached below. Blood Type A individuals tend to have Anti-B antibodies in their plasma, while Blood Type B individuals have Anti-A antibodies. Meanwhile individuals with Blood Type AB have none and individuals of Blood Type O have both.
Answer:
The correct answer is - The labyrinthodont.
Explanation:
Fossils of These duck billed dinosaur were found in the Antarctica in sands that were 66 to 67 million years old, however these are also found in north America and north Europe.
About 110 million years ago, labyrinthodonts, the dinosaur that are amphibians. These are the animals that were lived in the river valleys of the Gondwana and the rift valley that was located at that time between Australia and Antarctica.
Thus, the correct answer is - The labyrinthodont.
The first living things on Earth, single-celled micro-organisms or microbes lacking a cell nucleus or cell membrane known as prokaryotes, seem to have first appeared on Earth almost four billion years ago, just a few hundred million years after the formation of the Earth itself.
