Answer 2

All of the following events occur during prophase in mitosis except crossing over (Option B)

Mitosis can be divided into four phases: prophase, metaphase, anaphase, and telophase.

During prophase, the chromatids condense into chromosomes, thereby making them visible.

The mitotic spindle is a structure composed of microtubule proteins that segregate the chromosomes in mitosis. This structure is formed in prophase.

In Prophase homologous pairs of chromosomes are paired together. In metaphase, these chromosomes are lined up at the equator of the cell and sister chromatids are attached to the spindle fiber.

Crossing over (or recombination) is the exchange of genetic material between non-sister chromatids that occurs during prophase I of meiosis.

In conclusion, condensation of DNA, the pairing of chromosomes and, spindle formation occur during prophase, whereas crossing over occurs in prophase I of meiotic cell division (Option B).

what are catabolic reactions

Answers

Answer:

which complex molecules are broken down to simpler components, are classified as catabolic reactions. Taken as a group of reactions within a cell or even an organism, they can be referred to as the cell's or organism's anabolism or catabolism.

Explanation:

Catabolic reactions are a type of metabolic reaction that take place within a cell. Larger molecules are separated to form smaller molecules, as in the case of respiration where glucose is broken down to form carbon dioxide and water. Often they are hydrolysis reactions in which water molecules are used to break bonds.

Which letter marks the zone of inhibition?

Answers

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:

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

Answers

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.

Answers

Answer:

Hello!!! Princess Sakura here ^^

Explanation:

First things first if we are going to form a hypothesis it doesn't matter if it is correct hypothesis are supposed to get tested.

So anyways....

I believe that the solubility of oxygen will decrease as the temperature increase.

I believed that because as temperature increases molecules start to move faster and move farther away from each other.

Temperature can have a significant impact on the concentration of oxygen in various environments. 1) Solubility of Gases, Oxygen Dissociation, Biological Processes.

Here's a step-by-step explanation of how temperature affects oxygen concentrations:

1. Solubility of Gases: The solubility of gases, including oxygen, in a liquid like water is affected by temperature. Generally, as temperature increases, the solubility of gases decreases. This means that at higher temperatures, less oxygen can dissolve in water or any other liquid.

2. Oxygen Dissociation: In the context of the human body, temperature affects the dissociation of oxygen from hemoglobin in red blood cells. As temperature increases, the affinity between oxygen and hemoglobin decreases. This means that oxygen is more readily released from hemoglobin and made available to tissues and organs. Conversely, as temperature decreases, the affinity between oxygen and hemoglobin increases, making it more difficult for oxygen to be released.

3. Biological Processes: Temperature also affects the metabolic rates of organisms. Generally, as temperature increases, metabolic rates increase, leading to higher oxygen consumption. For example, in aquatic ecosystems, warmer water temperatures can enhance metabolic rates of aquatic organisms, leading to increased oxygen demand. Conversely, lower temperatures can slow down metabolic rates and reduce oxygen demand.

It's important to note that the specific effects of temperature on oxygen concentrations can vary depending on the system or environment being studied. Different factors such as pressure, salinity, and the presence of other substances can also influence the relationship between temperature and oxygen concentrations.

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.

Answers

If the red-eye parents are homozygous, no. But if the red-eye parents are heterozygous, yes.

Monohybrid crossing

We 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.
