Answer/Explanation:
Given==> short tail allele (T) is dominant, and long tail allele (t) is recessive.
Genotype of homozygous short-tailed dog = TT, while genotype of heterozygous short-tailed dog = TT
Required==> Punnett Square showing a genetic cross between both parents: i.e. TT X Tt
*See attached image for the Punnett Square
From the Punnett Square, 50% of the offspring of the First generation would be homozygous short-tailed, while 50% would be heterozygous short-tailed.
All the offspring would be all short-tailed as well.
Answer:
Hepatitis A
Explanation
Hepatitis A is caused by is caused by Hepatitis A virus which infects the liver and causes an inflammation.
The virus for Hepatitis A is spread through eating or drinking something contaminated with fecal matter and it is highly contagious.
However, it is preventable by vaccination.
Since it is a food borne disease which is highly contagious, a food handler has to be excluded from operation and a medical practitioner has to determine when the person can resume to avoid further transmission.
Answer:
(Leveling off = it stays the same even though it had a increasing period) When looking at the end of the graph you can see that it came back to what it was, which means the rotifers are not increasing anymore. That's because of the carrying capacity (a species' average population size in a particular habitat), and the carrying capacity in this situation is the flask. Therefore the flask has limited space.
Because it starts with "although", you realize there is a negative point coming in the second part of the sentence, which leads us to C and D. However, D is the one which is correct, because, in fact the genetic variation is diminished by the process of cloning. The new living organism created is a copy of some other. This way, it has the same DNA. If it the were a traditional case of reproduction, the new living organism would have a different DNA code, which leads us to answer D.
