One of the common arguments why the process of transplanting non-human organs which came from animals may be considered as an ethical act is that antigens on the surface of the non-human organs are not significantly rejected in the process. Although its research is still substantial, it is still considered as a matter of ethical issue.
Answer:
The S naked flasks allowed the air to pass into the flask, but the curve design retained any airborne microorganism that contaminate the broth
Explanation:
- The theory of spontaneous generation supported the idea that new living organisms arise spontaneously from non living matter.
- This theory was disapproved by the experiments conducted by Louis Pasteur.
- In his set of experiments, Pasteur took two flasks in which he added nutrient broths.
- He bent the neck of the flasks containing the broth into an S-shape and then boiled the broth in order to kill any microbe that was present in the broth.
- After this, Pasteur broke off the S shape neck of one flask but not the other. This led the first flask to come into contact with air and also allowed microbes and dust particles to contaminate the broth.
- After a few days, it was observed that the broth in the broken neck flask became cloudy indicating microbial growth while the broth in the other S-shaped neck flask showed no growth.
- This was possible because the <em>S shaped neck flask did not allow any microbe to contaminate the broth. </em>

Answer:
Woman's genotype is AO
Man's genotype is BO
Explanation:
For a woman with blood group A and a man with blood group B to give birth to a child with blood group O. Their genotypes will be:
Woman's genotype is AO
Man's genotype is BO
The can have a child with blood group A, B, AB and O
1/4 will have type AB blood group;
1/4 will have AO, which is type A blood group;
1/4 will have BO, which is type B blood group;
1/4 will have OO, which is type O blood group
<u>T cells lymphocytes </u>are a type of white blood cell that actively target and destroy infected cells via the production of antibodies.
A <u>pneumotachometer</u> actually measures <u>Air</u><u> </u><u>flow</u><u> </u>by sensing the <u>pressure</u> on ethier side of a fine mesh screen.
so, correct option is :
=》O Air Flow: Pressure
