Answer:
D. toxins
Explanation:
<u>Toxins are not microorganisms</u>, in fact they are non-living substances/chemicals which can cause infection in our body. Toxins may be produced by microorganisms but they are themselves not microorganisms. Some of the examples of toxins produced by microorganisms are botulinum toxin A, tetanus toxin A, muscarine etc.
Other options can refer to potentially infectious type of microorganisms. Option A. talks about microbes, among microbes some are pathogenic. Option B. talks about pathogenic, as the name indicates will be infectious for sure.
Option C. talks about nonpathogenic, it may be non pathogenic at a time but later on it can be pathogenic. For example: some vaccines use inactivated microbes which are non pathogenic for generating antibodies in the body but later on in the human body when they get optimum conditions for growth they can turn pathogenic and start infecting our body.
Answer:
Explanation:
The plate were supposed to streak by D. radiodurans but unfortunately it was streaked by E.coli.
As there is no other petri plate available, this plate was exposed to the UV for the 30 minutes. The plate was not left uncovered and because of that the total E.coli could not die and another streak of D. radiodurans was done on the same plate.
As a result of incubation there will be growth of both of the organism in the petri dish.
If there was a dramatic increase in skeletal muscle cell damage and apoptosis, I would not expect a change in blood myoglobin and CK levels, because these markers are linked to cardiac muscle damage.
<h3>What does high CK-MB mean?</h3>
Elevated CKMB can be a sign of cardiac (heart muscle) damage or chronic kidney failure. At the onset of acute symptoms, after cardiac peaks, CKMB values are elevated after 3-6 peaks after 12-24 hours between 12-24 hours, values at 24-48-48.
With this information, we can conclude that if there was a dramatic increase in skeletal muscle cell damage and apoptosis, we would not expect a change in blood myoglobin and CK levels, because these markers are linked to cardiac muscle damage.

Answer: C). 50%
Explanation:
The possible genotypes of the offsprings are Gg and gg. Gg has a dominant gene G for glossy leaves and so will manifest as glossy leaves because G is dominant over g which is recessive. Fifty percent of the offsprings will have glossy leaves while the remaining fifty percent will have nonglossy leaves.
See the attached punnet square for illustration.
