Blood A can receive from A and O
Blood B can receive from B and O
Blood AB can receive from anyone
I’m not sure of blood O however but I’m pretty sure they can receive from A and O
Since, the options have not been given, the question is incomplete. The complete question is as follows.
When Alexander Fleming discovered what was to become penicillin, he noticed that wherever mold was growing on plates of Staphylococus sp., there was a zone of inhibition of bacterial growth around the fungi. What type of symbiotic relationship does this describe?
A) Amensalistic
B) Cooperative
C) Mutualistic
Answer: A) Amensalistic
Explanation:
Amensalism is a symbiotic relationship between organisms that belong to different species, in this one organism is destroyed or inhibited in terms of growth and distribution but the other organism remains unaffected.
The given situation is the result of amensalism this is because of the fact that penicillin contains a fungal formulation which is likely to destroy the bacterial cells of Staphylococus sp. by creating a zone of inhibiting. Here, the fungal species will remain unaffected but the bacterial species will be inhibited.
Answer:
The population suffered a genetic bottleneck, which decreased genetic variation and thereby randomly increasing the frequency of harmful alleles
Explanation:
A population bottleneck, also known as genetic bottleneck, can be defined as a drastic reduction in the size of a population, which may be caused by anthropic activity and/or environmental phenomena (e.g., earthquakes, famines, fires, droughts, etc). A genetic bottleneck leads to a reduction in genetic variability within a population. Moreover, the genetic drifit caused by a genetic bottleneck can also increase the frequency of harmful alleles/mutations (it is due to the random sampling of individuals), thereby increasing the frequency of deleterious alleles/mutations in the population.
