The driving force for the movement of air into the lungs is the pressure. Our lungs is one of the primary organs of our body in order to perform the process of respiration. The answer to the following question is the pressure.It is the force that is applied for the movement of air into the lungs.
Answer:
C
Explanation:
The correct answer would be <u>a genotype that was different from that of both parents.</u>
Let us assume that the allele for height is A (for tall) and a (for short). Homzygous tall plant would have the genotype AA while homzygous short plant would have the genotype aa. Crossing both genotypes:
AA x aa
Aa Aa Aa Aa
<em>All of the offspring, even though have the same phenotype as one of the parents, have unique genotype from either of the parents. While the parents are AA/aa, the offspring are Aa.</em>
The correct option is, therefore, C.
Answer:
B. When beetroot cells are placed in a solution with cellulase, the solution remains clear.
Explanation:
Cell membrane are not destroyed or damaged as cellulase digests cellulose, rather it damages the structure of the cell wall.
In conclusion, even though the Beetroot cell wall has been damaged, the lack of change in the color of the solution suggests that the betalain is not leaking out thereby refuting the claim that the alternative hypothesis that selective permeability is a consequence of the cell wall.
Answer:
B- homology
Explanation:
If you look at the definition of homology, you can see that it compares the two organisms to see what is similar about them.
Explanation:
Dental caries is the demineralization of hard tissues on teeth by acid produced by organisms that reside in the dental plaque such as <em>Streptococcus mutants </em>and <em>lactobacilli</em>.
The BCG Dextrose Agar, also known as Snyder Test Agar is a colorimetric analysis used for the estimation of Lactobacilli counts in saliva. I<em>n this test, glucose is used as the fermentable carbohydrate and Bromcresol Green as the pH indicator. If Lactobacillus spp. are present the glucose fermentation will cause the pH to drop to 4.4, changing the color from blue-green to yellow,</em> this will confirm the susceptibility of a person to develop dental caries based on acid production.
A differential contains specific ingredients to distinguish a bacteria from another one through observation, in this case,<em> the detection of acidity with the bromocresol green indicator will be the factor that will allow us to differentiate Lactobacilli from another organism.</em>
