Answer: oxygen diffuses from alveolar sacs to blood in capillaries

Cellular respiration is a metabolic process that occurs in all organisms. In humans the process of respiration is highly complex. The respiratory system in humans involves a set of organs that allows an individual to breathe and exchange gases (oxygen and carbon dioxide) throughout the body. In humans the respiratory system includes organs like nasal passage (nose), larynx, trachea, bronchial tubes, alveoli and lungs.

The lungs are the main organs which provides a platform for gas exchange occurring in a body. The oxygenated air when enters the lungs, passes into tube like structures called as alveolar sacs. The blood inside the alveolar sacs passes into the fine blood vessel network called as capillaries. The capillaries provide a surface when the carbon dioxide present in the blood gets replaced with the oxygen. The carbon dioxide exhaled out from the body and the oxygen is transported to the all the body organs and cells.

What does the graph show the importance of clean air?
natulia [17]

Answer:

C. Most people will die from negative health effects associated with stroke as indoor dirty air builds up.

Explanation:

<u>C is correct option</u> because it shows the highest proportion of people's death caused by stroke. On the other options are not correct due to the following reasons:

A is incorrect because it says that people have a lower risk of dying from COPD. On the other hand, the graph shows that this is 3rd most abundant cause of deaths.

B is incorrect because deaths due to lung cancer are the lowest according to the graphical illustration.

D is incorrect because the proportion of developing acute lower respiratory infection and ischemic heart disease are not the same. Deaths due to ischemic heart disease are higher than the acute lower respiratory infection.

Predict what the calf produced in a union between each of these parents might look like. Explain your answers.
Charra [1.4K]
We know that purebred means that the organism contains the same alleles for the trait and hybrid means that it contains two different alleles for the trait. Dominant means that it will be shown in a hybrid and a purebred, but recessive traits will only be shown in purebred recessive organisms.

a) The offspring of a purebred white (recessive) cow and a purebred brown (dominant) bull, would be all hybrid brown (dominant). This is because as I stated above, dominant traits are shown when the offspring has both dominant and recessive alleles for the same trait.

b) The offspring of a purebred brown (dominant) cow and a purebred brown (dominant) bull would all be purebred brown (dominant). This is because if both of the parents have only alleles that code for brown color, the only color that the offspring can be is brown.

c) The offspring of a purebred white (recessive) cow and a purebred white (recessive ) bull would all be purebred white (recessive), for the same reason stated above in part b), the only difference being that the alleles are recessive and code for white color instead of being dominant and coding for brown color.

d) The offspring of a hybrid brown (dominant) cow and a purebred white (recessive) bull would be half hybrid brown (dominant) and half purebred white (recessive). This can be seen best if you set up a Punnett Square, which is a diagram that shows allele frequencies in offspring. This shows you that the chance that the offspring get the dominant allele from the mother cow is 50%, thus 50% would be hybrid brown (dominant), as the father can contribute only a recessive white allele. The other 50% would be purebred white (recessive) because the mother cow would be contributing a white allele and so would the father.

Hope this helps! :)

Why are lipophilic chemicals of greater concern to endocrine disruption?
ad-work [718]
An endocrine disruptor is an exogenous substance or mixture that alters the function of the endocrine system and consequently causes adverse health effects in an organism. Lipophilic chemicals are those that do not dissolve in water and have the ability to dissolve in non -polar substances and they have been linked to cause numerous diseases in humans.
