Explanation:
Which letter marks the zone of inhibition?
Answer:
A. B
Explanation:
"B" as labelled in the above is the zone of inhibition.
The Zone of Inhibition is actually a test which is used to assess antimicrobial activities of a material or solution in relation to an micro-organism as a target. It is also known as Kirby-Bauer Test. It measures the antibiotic resistance and also used to inhibit microbial growth.
At the Point B, microbes can not grow in there; they are inhibited.
In the test, if bacterial strain or any other strain is susceptible to the antimicrobial agent, a zone of inhibition appears. If it shows resistance to that agent, then no zone is evidential.

Explanation:
The interactions between human population dynamics and the environment have often been viewed mechanistically. This review elucidates the complexities and contextual specificities of population-environment relationships in a number of domains. It explores the ways in which demographers and other social scientists have sought to understand the relationships among a full range of population dynamics (e.g., population size, growth, density, age and sex composition, migration, urbanization, vital rates) and environmental changes. The chapter briefly reviews a number of the theories for understanding population and the environment and then proceeds to provide a state-of-the-art review of studies that have examined population dynamics and their relationship to five environmental issue areas. The review concludes by relating population-environment research to emerging work on human-environment systems.

Which evidence from the Hershey-Chase experiment demonstrated that DNA, not protein, is the genetic material
Answer:
The evidence from the Hershey-Chase experiment demonstrated that DNA, not protein, is the genetic material DNA contains phosphorus, but protein does not was as result of some analysis in which it was discovered that Protein contains sulfur and DNA does not.
This was what led to the use of radioactive phosphorus and radioactive sulfur in self-identification.

If a red-eye female fly is crossed with a red-eye male fly, could they produce offspring with white eyes? Briefly explain your answer. Your answer must include a Punnett square that proves your answer.
If the red-eye parents are homozygous, no. But if the red-eye parents are heterozygous, yes.
Monohybrid crossingWe are assuming that the red-eye trait is dominant over the white-eye trait. If two red-eye parents are crossed with one another, whether they could produce white-eye offspring would depend on the zygosity level of the parents.
Assuming that red-eye is R and white-eye is r. If the two parents are homozygous red-eyed, their genotypes would be RR. Crossing the two:
RR x RR
RR RR RR RR
All the offsprings would be RR and there is a zero chance of producing a white-eye offspring.
Now, assuming that the two parents are heterozygous:
Rr x Rr
RR Rr Rr rr
Both RR and Rr are red-eyed while rr is white-eyed. The Punnet's square for the cross can be found in the attached image.
In other words, it will only be possible for the two red-eye parents to produce white-eye offspring if they are both heterozygous. Any other genotype will give a zero chance of white-eye offspring.

i. All organisms are made of cells.
ii. All existing cells are produced by other living cells.
iii. The cell is the most basic unit of life.
7. Cell theory is one of the great unifying theories of biology
Explanation:
Cell theory is one of the central theories of biology and is universally accepted. It states that all organisms are cellular - that is they are made of cells. It also states that all living things come from other living cells (not spontaneously, or from dead cells). The cell is the most basic unit of life, organisms can be unicellular, but no living thing is 'less' than that.

Which answer best explains how most scientists think that planets form? A. Large chunks of matter break off a star that collides with another star; these chunks then become planets orbiting the star. B. Large chunks of matter break off a planet that collides with a smaller body; these chunks gradually clump together to become a new planet. C. A rotating cloud of space dust and gases begins to flatten and condense, forming a new star; the remaining matter forms an accretionary disc around the star, gradually coalescing to form planets. D. A rotating cloud of space dust and gases begins to condense, forming a protoplanet; if the protoplanet is massive enough, its gravity will attract nearby matter until the protoplanet becomes large and round enough to be considered a planet.
Answer: B
Explanation:
Thats what the teacher told me
The scientists believe that planets form when a rotating cloud of space dust and gases flattens and condenses, forming a new star; the remaining matter forms an accretionary disc around the star, gradually coalescing to form planets, as described in Option C, also known as the "nebular hypothesis."
What is the nebular hypothesis?The nebular hypothesis is the most widely accepted scientific theory for the planetary systems, such that the solar system and, as per this theory, a cloud of gas and dust, called a nebula, collapse due to gravitational forces; the nebula contracts, and it rotates faster, flattening into a disk, which eventually cools and condenses, forming a protoplanetary disk.
Hence, the scientists believe that planets form when a rotating cloud of space dust and gases flattens and condenses, forming a new star; the remaining matter forms an accretionary disc around the star, gradually coalescing to form planets, as described in Option C, also known as the "nebular hypothesis."

There are many reasons why all humans do not perceive sounds similarly in our environment, including adaptation, hearing loss and/or deafness.
For 2A-2D, first determine whether the scenario is an example of sensory adaptation, conduction deafness, sensorineural deafness, and/or central deafness.
Second, for the scenarios that are examples of deafness, explain briefly how the scenario leads to deafness (i.e., how does the scenario alter normal auditory processing). If you have selected sensory adaptation as an answer, explain briefly why the scenario does not fall under the categorization of deafness. Use your own words to briefly explain - simply listing definitions is not sufficient. (2.5 points each for matching, 5 points each for correct justification)
2A. Listening to excessive loud noises everyday over years that causes loss of stereocilia
2B. Hearing construction outside when it first begins, but no longer noticing the sound minutes later
2C. Difficulty understanding speech, but no damage to ears or ability to understand nonverbal sounds
2D. A hole in the tympanic membrane caused by an ear infection
Answer: 2A Sensorineural deafness
2B Sensory adaptation
2C Central deafness
2D Conductive deafness
Explanation: The human ear is divided into 3 parts:
Outer Ear: auricle, ear canal and tympanic membrane;Middle Ear: eardrum, tympanic cavity and ossicles (malleus, incus and stapes);Inner Ear: oval window, semicircular ducts (attached to cochlea and nerves), cochlea and auditory tube;The Sensorineural deafness is a type of deafness caused by a damage in the inner ear, either the cochlea or the auditory nerve. It can happen because of medicine toxicity, exposure to noise along the years etc.
So, from the scenarios above, 2A is consistent with sensorineural deafness since stereocilia are hair cells of inner ear.
Sensory adaptation is a phenomenom that happens when an individual's sensory receptors is exposed to a stimuli for a prolonged period of time. For example, the situation described in 2B. It is not considered deafness because it is not caused by a damage in any part of the ear.
Central deafness is a very rare case of deafness. The damage in this type of deafness is in the brain and not in any of the 3 parts of the ear. That's why the scenario in 2C is the example of this.
Conductive deafness is the second most common type of ear problem and it occurs in the outer ear. One of the causes is blockage in the ear canal by the ear wax, external bodies, osteomas (bone growth) or otitis (oute ear infection). An example of this type of deafness is scenario 2D.
