Answer:
Pollen from a yellow daisy travels across a stream and pollinates an orange daisy.
Explanation:
Gene flow refers to the movement of genes from one population to another population of the same kind.
From the alternatives given, Pollen movement from a yellow daisy across a stream to pollinate an orange daisy is an example of gene flow
Answer: Pollen from a yellow daisy travels across a stream and pollinates an orange daisy.
Explanation:
The gene flow can be define as the transfer of the genetic variation typically from one population to the other. If the rate of flow of gene is high enough, the two population in which the gene flow has occurred will become equivalent in allele frequencies and therefore will become the single population.
Pollen from a yellow daisy travels across a stream and pollinates an orange daisy. is the correct option, this is because of the fact that through pollen which is the male gamete the genetic variations are passing from one population to another population of the same species of daisy. Thus the allelic frequencies will become the equivalent in the two populations of the same species. Thus this will result in the formation of the single population.

No, fish cannot see water like we cannot see air. Did this help?
great question ! i guess they don't, since we don't see air. And air is kinda like water for them, so I'd say no they don't see water.
In 1983 a hospital-acquired intestinal infection caused by the bacterium Enterococcus faecium joined the list of bacteria that could not be killed by penicillin.
Which of these BEST describes why certain bacteria have become resistant to penicillin?
A) The penicillin in the 1970's was much weaker that the penicillin used today, thus it was not as effective.
B) Penicillin was not effective in treating any bacterial diseases, so the doctors had to find new treatments.
C) These new bacterial strains came out of the jungles and forests already equipped to be penicillin-resistant.
D) Penicillin was so heavily prescribed by doctors that it led to certain, more fit, strains of bacteria to be able to survive.
2)
I think B but i’m not for sure
Answer:
D. Penicillin was so heavily prescribed by doctors that it led to certain, more fit, strains of bacteria to be able to survive.
Explanation:
Researchers thought penicillin was the cure for all, and thus it became overused. Through natural selection, new, stronger strains of bacteria developed.
Answer: 10%
Explanation:
It is determine by the combination of efficiencies associated with organismic resource Acquisition and assimilation in an ecosystem.so the amount of energy at each tropic level decreases when it goes to the next level via ecosystem. As little as 10% of the energy at any tropic level is transferred to the next level, remaining energy is lost due to the metabolic process in the form of heat.
