a) lymph. 
b) interstitial fluid. 
c) extracellular fluid (ECF). 
d) plasma.

All the following are correct terms for this fluid except lymph.

Mark is on a strict diet. He has cut down on fats in order to lose weight. Because Mark is severely restricting his fat intake,
timofeeve [1]
<span>Mark may be getting lower amounts of nutrients and vitamins, namely omega-3s and omega-6s. This would directly affect the brain and normal body functions because the body needs vitamins/nutrients to thrive. This could affect the chemical balance in his brain, resulting in depression/schizophrenia/other issues, including eating disorders. Cutting down on fats might also result in overeating carbs and protein, which leads to an overbalance of nutrients -- and a host of other health issues.Not getting enough fat could also affect bone growth.</span>

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.

Which of the following are true of epigenetic changes?
Iteru [2.4K]

Answer:

all of the above

Explanation:

Epigenetic alterations are modifications of the genome transmitted during cell division, which do not involve changes in the DNA sequence, are hereditary and are capable of modifying gene expression. In addition, they are temporary modifications that allow DNA to be transcribed and have the ability to move histones to open or close a chromosomal region. There are three main mechanisms of epigenetic alterations: DNA methylation, histone modifications and genomic imprinting.
