Answer:

Anaphase

Explanation:

The sister chromatids separate from each other and are pulled toward opposite ends of the cell.  Each is now its own chromosome. The chromosomes of each pair are pulled towards opposite ends of the cell.

Answer:

Anaphase

Explanation:

After metaphase is complete, the cell enters anaphase. During anaphase, the microtubules attached to the kinetochores contract, which pulls the sister chromatids apart and toward opposite poles of the cell . At this point, each chromatid is considered a separate chromosome.

Answer:

The tenet of cell theory that BEST serves as a basis for this type of biotechnology is that all living things are composed of cells.

Cell theory states that all living things are composed of one or more cells and that the cell is the basic unit of life. In biotechnology, genes that code for a specific protein can be inserted into bacterial plasmids, which are small circular pieces of DNA found in bacteria, and then the plasmids are used to transform cells. The transformed cells can then produce the desired protein. This process is based on the understanding that all living things are composed of cells and that the genetic information necessary to produce specific proteins is contained within the cell's DNA. Without this understanding of the basic unit of life being the cell, it would not be possible to create transgenic bacteria to synthesize human proteins for medical use.

1) Prospective cohort study. 2) Table below. 3) Relative risk = 2.466. 4) The risk of developing asthma is greater in people exposed to the pesticide than in people not exposed to it. 5) Not knowing other risk factors that could cause asthma.

Prospective and retrospective studies are carried out depending on the aim of the research.

Individuals from the study groups in these cases have already been affected.

Most individuals from the study groups in these cases have not been affected. However, some of them might have been or might have high risks of being affected.

1)

The exposed study case is an example of a prospective cohort study.

It analyzes the connection (relationship) between being exposed to the pesticide and being affected by asthma.

It is carried out to predict if people exposed to pesticides have more chances of developing asthma or not.

2) Data

Pesticide Expossure          Asthmatic        Not Asmathic     Total

Yes                                            69                       249               318

No                                              87                       903               990

Total                                          156                      1152              1308

3) Measures of association

Exposed people

attack rate = affected people with asthma / exposed people

attack rate =  69/318

attack rate = 0.217

Attack rate for peope exposed to pesticide, ARE = 0.217

Not Exposed people

attack rate = affected people with asthma / not exposed people

attack rate =  87/990

attack rate = 0.088

Attack rate for peope not exposed to pesticide, ARNE = 0.088

Being exposed

Relative risk = ARE / ARNE

Relative risk = 0.217 / 0.088

Relative risk = 2.466

4) Interpretation:

In the exposed example, relative risk is greater than 1 (Rr>1)

This means that the risk of developing asthma is greater in people exposed to the pesticide than in people not exposed to it.

Pesticide exposure might be a significant risk factor for asthma development.

5) Weakness of this study design  

A weakness of the study could be that no other risk factor is considered.

There could be another factor affecting people and causing asthma development. This factor could be affecting both groups.

Explanation:

Glycogenolysis can still occur during exercise even if a person is administered a drug that blocks the Beta receptors for norepinephrine. This is because glycogenolysis is mainly regulated by the hormones epinephrine and glucagon, which are released from the adrenal glands and do not require norepinephrine for activation. Therefore, blocking the Beta receptors for norepinephrine has no effect on glycogenolysis.

Vanessa has a better absolute threshold and more sensitive difference threshold than Carlton, and Carlton has an impaired absolute threshold.

Carlton and Vanessa were lab partners for a biology class and were asked to run a smell test experiment on each other.

Vanessa was excellent at noticing the difference between various intensities of vanilla and evergreen.

Carlton, on the other hand, couldn't distinguish the difference in the intensities of both vanilla and evergreen, though he could tell the smells of both.

Hence, based on the information provided in the scenario, it can be inferred that Vanessa has a more sensitive difference threshold than Carlton, and Carlton has an impaired absolute threshold.

The two significant aspects that are involved in the scenario are absolute threshold and difference threshold.

The absolute threshold is the smallest quantity of a stimulus that an individual can detect, whereas the difference threshold is the minimum difference in stimuli that an individual can detect.

Carlton could recognize the stimuli's smell but not the difference in the intensity of vanilla and evergreen.

This shows that Carlton has an impaired absolute threshold.

He could not detect the smallest quantity of a stimulus to differentiate between the smells.

Vanessa was quite good at noticing the difference in the intensities of vanilla and evergreen.

This means that Vanessa has a more sensitive difference threshold than Carlton. She could detect the minimum difference in stimuli required to differentiate between smells.

Vanessa also has a better absolute threshold than Carlton as she could detect the smallest quantity of stimulus required to detect the smells.

An argument to support the claim that ice cooling is a good way to cool large buildings is that it is a more efficient and cost-effective method than traditional air conditioning. Ice cooling works by storing energy in the form of ice during off-peak hours, and then using the stored energy to cool the building during peak hours. This reduces the amount of energy needed to cool the building, resulting in lower energy costs. Additionally, ice cooling systems are more efficient than traditional air conditioning systems, as they are able to maintain a more consistent temperature throughout the building.

I also know that traditional air conditioning systems are not as efficient as ice cooling systems, as they require more energy to cool the building. Additionally, traditional air conditioning systems are not as effective at maintaining a consistent temperature throughout the building, as they are more prone to fluctuations in temperature. This can lead to uncomfortable temperatures in certain areas of the building.
