Air that enters the pleural space during inspiration but is unable to exit during expiration creates a condition called Pneumothorax.

<h3>What is Pneumothorax?</h3>

An abnormal buildup of air in the pleural space between the lung and the chest wall is known as a pneumothorax. Shortness of breath and quick, acute, one-sided chest discomfort are common symptoms . A tension pneumothorax happens when an area of injured tissue forms a one-way valve, increasing the amount of air in the gap between the chest wall and the lungs. As a result, there may be an oxygen deficiency that worsens with time and low blood pressure. Obstructive shock is a type of shock that results from this and can be lethal if left untreated. A pneumothorax can very infrequently affect both lungs. Although the term "collapsed lung" can also refer to atelectasis, it is frequently used to describe it.

Hypothesis:

AleksandrR [38]

Answer:

Objective(s):

In your own words, what was the purpose of this lab?

In this lab report, the purpose is that hamsters carry traits fro parents.

Hypothesis:

In this section, please include the if/then statements you developed during your lab activity. These statements reflect your predicted outcomes for the experiment.

Test One: If I breed a short fur, FF female with a short fur, Ff male, then I will expect to see (all short fur; some short and some long fur; all long fur) offspring.

All short fur

Test Two: If I breed a short fur, Ff female with a short fur, Ff male, then I will expect to see (all short fur; some short and some long fur; all long fur) offspring.

Some short and some long

Test Three: If I breed a long fur, ff female with a long fur, ff male, then I will expect to see (all short fur; some short and some long fur; all long fur) offspring.

All long fur

Procedure:

The procedures are listed in your virtual lab. You do not need to repeat them here. Please be sure to identify the test variable (independent variable) and the outcome variable (dependent variable) for this investigation.

Remember, the test variable is what is changing in this investigation. The outcome variable is what you are measuring in this investigation.

Test variable (independent variable): Outcome variable (dependent variable):

Conclusion:

Your conclusion will include a summary of the lab results and an interpretation of the results. Please write in complete sentences.

1. Which genotype(s) and phenotype for fur length are dominant? FF

2. Which genotype(s) and phenotype for fur length are recessive? ff

3. If you have a hamster with short fur, what possible genotypes could the hamster have? It would probably be Ff or a ff

4. If you have a hamster with long fur, what possible genotypes could the hamster have? It would be Ff or an FF

5. Did your data support your hypotheses? Use evidence to support your answer for each test.

From deep to superficial, the order of the strata of the epidermis is corneum - granulosum - lucidum - spinosum - basale. spinos

kotykmax [81]

Answer:

basale - spinosum - granulosum - lucidum - corneum.

Explanation:

The order of strata in the epidermis:

Basale: it is the deepest stratum. It has one layer of cells called keratinocytes, which are stem cells for the epidermis.
Spinosum: The keratinocytes in this layer have spiny shapes. They synthesize cytokeratin and lipids. In this layer, we can also find macrophages.
Granulosum: The keratinocytes of the previous layer ascend and synthesize keratohyalin, which is in granules. The keratohyalin helps to join keratin filaments. Also, the cells release the lipids synthesized in the previous layer, and they form a barrier that stops dehydration.
Lucidum: it is only on thick skin, like the one in the sole of the feet. The keratinocytes in this layer have expelled the nucleus and now are dead cells. The keratinocytes have a flat shape and form a thin layer.
Corneum: it is the most superficial layer. It is made of dead keratinocytes filled with keratin in their cytoplasm. It is a thick layer that suffers desquamation when new dead cells filled with keratin ascend from the previous layer.
