Phat1 = 9/142
Phat 2 = 5/268
Phat 3 14/410
Test statistics = (Phat 1 - Phat 2) / (Square root of (phat × (1- phat))
times the square root of (1/n1 + 1/n2))
Test statistics = 2.373
P- value = 2× (1- normal cdf (2.373, 0, 1))
= 0.0176
At the level of significance, there is difference between the proportion of drug-resistant wihtin the two states.
Out of the options I would have to say Penetrating Keratoplasty, I am not sure
Answer: When the DNA collected on the crime scene is being analysed in the forensic lab, the results will be inconclusive, because error in DNA transcription, particularly in mRNA encoding leads to inheritable phenotype change by reprogramming the transcriptional network, without changing the DNA. Transcription errors are brief with no long-term consequences. Due to mRNA being short-lived and the erroneous proteins are degraded. A decrease in transcription accuracy triggers cellular identity change.
Explanation: This is called epimutation, a heritable modification that results in the change of gene expression, but not the DNA sequence. Epimutation is not associated with DNA mutation, but is associated with the loss or gain of DNA methylation or other heritable changes of the chromatin.
The answer is <span>The flagellated sperm would not be able to swim to the eggs for fertilization.
</span><span>Their life cycle of mosses has alternation of generation -
a haploid gametophyte and a diploid sporophyte. Gametophyte produces haploid
gametes which fuse to form a diploid zygote. The zygote grows into diploid
sporophyte which produces haploid spores. The spores grow into gametophyte and
the cycle begins again.
</span>Mosses require water for reproduction. Before fertilization, the sperm swims to an egg through the water. Therefore, mosses require water for successful fertilization. In drought periods, without water, the sperm cell could not swim to the egg cell.
