Alveolar type ________ (VIII) cells are responsible for producing surfactant
lord [1]

Answer:

Type II cells

Explanation:

Type II alveolar cells are the round-shaped or cuboidal epithelial cells. These cells have a free surface with microvilli. The function of the type II alveolar cells is to secrete the alveolar fluid to keep the surface of the cells moist.

A mixture of phospholipids and lipoproteins is present in the alveolar fluid that serves as surfactant and reduces the surface tension of the alveolar fluid. The overall effect of the presence of surfactant in alveolar fluid is to protect the alveoli against collapsing during exhalation.

A 27 year old G2P1 female presents to the emergency department in labor at 41 weeks estimated gestational age. The amniotic sac
prisoha [69]

Answer:

Option D

Explanation:

When amniotic sac breaks and its internal fluid spilled then there are high chances that the fluid may enter into the throat of the infant and may block his/her air passage way. Therefore, in such situation a standard solution is formulated which requires the doctors to suction the air passageway of infant and restrict it from getting choked and contaminated with meconium. A valve mask is primarily used before suctioning  

Hence, option D is correct

Having freckles (F) is dominant over not having freckles (f). A parent with freckles is crossed with a parent without freckles.
Step2247 [10]

Answer:

This is a trick question, and only because the question is vague

Explanation:

Use a Punnet Square to figure out the percentages.

If the parent with freckles (let's just call them Parent A) is homozygous dominant, their genotype would be FF.  The parent without freckles (Parent B) has a genotype of ff.

In any situation, the probability of these two having a child that is homozygous dominant for freckles is 0%.  (see punnet squares for more info).  

Now here's where it gets a little more confusing because the question is kind of vague on this.

Assuming that Parent A is homozygous dominant (both genes for this are dominant (FF)), then the probability of having a heterozygous (non-identical genotype letters, meaning they carry the recessive trait) genotype is 100%.  However, if Parent A is also heterozygous, then that percentage decreases to 50%

For Situation A (Parent A is homozygous dominant), the probability of a homozygous recessive genotype is 0%

For Situation B (Parent A is heterozygous dominant), the probability of a homozygous recessive child is 50%.

Please see the Punnet square I made for more information.

Key:

- Homozygous Dominant: FF

- Heterozygous Dominant: Ff

- Homozygous Recessive: ff

(heterozygous recessive does not exist, because that would mean one of the genes is dominant, which would overpower the recessive gene)

I really hope this helps, and if you're confused by this, please do not hesitate to let me know!
