We have that for the Question "since ph can affect the activity of the <u>antibiotics</u> why would the Kirby bauer test require that the agar have a ph of 7.4" it can be said that

  • Why the Kirby <u>bauer </u>test require that the agar have a ph of 7.4 is because while <em>agents </em>may be in excessive activity, given a scenario that the <em>pH </em>is to exceed 7.4 the results might inverse.

From the question we are told

since ph can <em>affect </em>the activity of the antibiotics why would the Kirby <u>bauer </u>test require that the agar have a ph of 7.4

Generally

Agar has a ph value that should exist between 7.2 and 7.4 within a room temperature,given it  solidifies and this should be when initially prepared

Therefore

Why the Kirby <u>bauer </u>test require that the agar have a ph of 7.4 is because

while <em>agents </em>may be in excessive activity, given a scenario that the <em>pH </em>is to exceed 7.4 the results might inverse.

Apply the principles of diffusion to explain what will occur after placing a dyed sugar cube in a beaker of water
snow_lady [41]

The molecules in the sugar move from an area of higher concentration (sugar cube) to an area of lower concentration in the water.

That is exactly what diffusion is: the net movement of molecules or atoms driven by a gradient , which means that it doesn’t requires energy.

If the two traits that Mendel looked at in his dihybrid cross of smooth yellow peas with wrinkled green peas had been controlled
nalin [4]

Answer:

c. Would have deviated from the 9:3:3:1 phenotypic ratio

Explanation:

<em>If two genes are linked together on the same chromosome, the phenotype of the F2 generation would have deviated from 9:3:3:1.</em>

Two genes whose loci are close on the same chromosome are said to be linked. Linked genes have higher frequency of recombination than genes that are not linked.

<u>Hence, while genes that are not linked assort independently to produce 9:3:3:1 phenotypic ratio at F2, linked genes do not assort independently and the higher frequency of recombination ensures that they standard phenotypic ratio is deviated from.</u>

The correct option is c.

lesya [120]

Explanation: Electron microscopes are the most powerful type of microscope, capable of distinguishing even individual atoms. However, these microscopes cannot be used to image living cells because the electrons destroy the samples.

Your brain and neurons are in constant action, sending billions of ___________and________messages each day to keep everything, f
Leviafan [203]

Answer:

Until recently, most neuroscientists thought we were born with all the neurons we were ever going to have. As children we might produce some new neurons to help build the pathways - called neural circuits - that act as information highways between different areas of the brain. But scientists believed that once a neural circuit was in place, adding any new neurons would disrupt the flow of information and disable the brain’s communication system.

In 1962, scientist Joseph Altman challenged this belief when he saw evidence of neurogenesis (the birth of neurons) in a region of the adult rat brain called the hippocampus. He later reported that newborn neurons migrated from their birthplace in the hippocampus to other parts of the brain. In 1979, another scientist, Michael Kaplan, confirmed Altman’s findings in the rat brain, and in 1983 he found neural precursor cells in the forebrain of an adult monkey.

These discoveries about neurogenesis in the adult brain were surprising to other researchers who didn’t think they could be true in humans. But in the early 1980s, a scientist trying to understand how birds learn to sing suggested that neuroscientists look again at neurogenesis in the adult brain and begin to see how it might make sense. In a series of experiments, Fernando Nottebohm and his research team showed that the numbers of neurons in the forebrains of male canaries dramatically increased during the mating season. This was the same time in which the birds had to learn new songs to attract females.

Why did these bird brains add neurons at such a critical time in learning? Nottebohm believed it was because fresh neurons helped store new song patterns within the neural circuits of the forebrain, the area of the brain that controls complex behaviors. These new neurons made learning possible. If birds made new neurons to help them remember and learn, Nottebohm thought the brains of mammals might too.

Other scientists believed these findings could not apply to mammals, but Elizabeth Gould later found evidence of newborn neurons in a distinct area of the brain in monkeys, and Fred Gage and Peter Eriksson showed that the adult human brain produced new neurons in a similar area.

For some neuroscientists, neurogenesis in the adult brain is still an unproven theory. But others think the evidence offers intriguing possibilities about the role of adult-generated neurons in learning and memory.
