Answer:
The correct option is: E. 70 square meters
Explanation:
Pulmonary alveoli is described as the cup-shaped hollow cavity, found in the alveolar sacs of mammalian lungs.
The alveolar membrane, also called the respiratory membrane, allows the exchange of gases. Across this membrane, carbon dioxide is released from the capillaries into the alveoli and oxygen is diffused from the alveoli into the capillaries.
<u>About 300 million alveoli are present in the lungs of a human, which makes about 70m² of surface area. </u>
Answer:
Anaerobic heterotroph
Explanation:
E. histolytica It is an anaerobic parasite of the protozoan family. It's anaerobic because they can survive within the human being's organism in the absence of oxygen. It is heterotrophic because it feeds on digested food in the intestine of its guests. It also kills and degrades nearby cells to ingest nutrients.
This amoeba causes diarrhea. Amebic colitis is one of the leading causes of diarrhea in the world, especially in developing countries.
I have provided the options below:
a. 150
b. 225
c. 300
d. 450
e. 75
Answer:
150
Explanation:
Hardy-Weinberg law states, the allelic frequencies of a gene that is, q and p follow the relationship p^2+q^2+2pq = 1, if the population is in equilibrium.
Therefore p^2+q^2+2pq = 1, can be used to calculate the percentage of the allelic frequencies i.e. p^2 and q^2
Allelic frequency = 0.75.
Therefore, the percentage of the allele in the population would be given by
0.75^2 = 0.5625 = 56%.
And the total number of individuals with this allele in the population:
number of individuals = 56×300÷100
= 168 or
150 nearest figure.
