Why are conifers so common in American forests?
tiny-mole [99]

Answer:

Answer is C

Explanation:

Coniferous forests grow in a wide range of climates, from the coldest polar regions to the warmest tropical regions and everything in between. The reason they're so prevalent worldwide is because they take advantage of certain environmental conditions that other trees aren't able to live in as well. Conifer trees are adapted for cold and harsh climates. ... The needle-like leaves are an important adaptation to Conifer trees because they do not accumulate much snow, keeping the weight load mild. Even though Tamarack trees lose their leaves in the winter, they are still subject to some snowfall.

How would a mistake in transcribing the DNA message affect your ability to catch the killer?
mel-nik [20]

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.
