Answer:
To demonstrate that the inhibition by Janthinobacterium lividum on chytrid found in adult amphibian skin is real, the best experimental design would be take infected amphibians and assign them to two populations. Leave one population alone; inoculate the other with Jl. Measure the rate at which infection proceeds in both populations (option C).
Explanation:
Chytrids -<em>Batrachochytrium dendrobatidis</em>- are a species of pathogenic fungi with affinity for amphibian skin, causing alteration of keratin and damage to the animal body.
The verification that Janthinobacterium lividum is capable of inhibiting amphibian skin chytrids requires the design of an experimental model, the most appropriate being that of an infected amphibian population exposed to the bacteria, while the other (control) is not exposed to J. lividum.
In theory, amphibians in the population exposed to bacteria should decrease chytrid infection, whereas in the normal population the infection would remain the same.
<span>The answer should be B. The results of a previous experiment are presented as an introduction to a new experiment.
Material that used for </span>presentation of background research should have a credible information. A<span>mazing new drug is described in a television commercial mostly false and it is not backed up by scientific study. Rumor from </span><span>second-hand accounts definitely not credible. A newspaper is not a scientific study and could give false information.</span>
Answer: C G A C C T A T G G G C... (and so on)
Explanation:
Think of this as one letter representing one half of a pair. The pairs are A and T, and C and G.
When you see a T, its opposite part of the pair is A, and vice versa. The same goes for C and G. To answer this, just write the opposite of what is there.
A -> T
T -> A
and,
C -> G
G -> C
Hope this helps!
