<u>Answer:</u>
Mitochondria, the organelles involved in cellular respiration, can also generate chemicals called reactive oxygen species (ROSs). ROSs can damage mitochondria. Damaged mitochondria generate more ROSs than healthy mitochondria. This is an example of a positive feedback mechanism
The reactive oxygen species that are given out by the mitochondria during cellular respiration are the major cause of aging. Though this has a lot of negative effects but this also has a small amount of positive effects such as the start of angiogenesis or cell proliferation.
What amino acid sequence does the following DNA nucleotide sequence specify?
3′−TACAGAACGGTA−5′
Express the sequence of amino acids using the three-letter abbreviations, separated by hyphens (e.g., Met-Ser-His-Lys-Gly).
A dichotomous key is very easy to use because it provides only two choices.
If you need a further explanation let me know!
Hope this helps!
Answer:
Saturated fatty acids have all of their carbon atoms bonded to hydrogen atoms.The lipids containing saturated fatty acid are solid at room temperature
Unsaturated fatty acids have some of their carbon atoms double bonded in place of hydrogen atoms.The lipids containing unsaturated fatty acids are liquid at room temprature.

Answer:
D. 1/64
Explanation:
The desired genotype for the progeny = aabbcc (homozygous recessive for all the three loci). The probability of getting a progeny with a homozygous recessive genotype can be calculated during the product rule.
The parent genotypes= AaBbCc x AaBbCc
Aa x Aa = 1/4 AA: 1/2 Aa: 1/4 aa
Bb x Bb = 1/4 BB: 1/2 Bb: 1/4 bb
Cc x Cc = 1/4 CC: 1/2 Cc: 1/4 cc
Therefore, the probability of getting a progeny which is homozygous recessive for all the three traits (aabbcc)= 1/4 aa x 1/4 bb x 1/4 cc = 1/64
