Answer:
increasing[1], higher[2], space[3], food[4], climate change[5].
Explanation:
Because global temperatures are <u>increasing[1]</u>, some species are seeking out <u>higher[2]</u> elevations in the Himalayas to colonize. Scientists were worried that these organisms would not have enough <u>space[3]</u> to live, but they have found that there is adequate <u>food[4]</u> at higher elevations. This movement may help these organisms survive the effects of <u>climate change[5].</u>
(Although am positive about 1, 2 and 5, you will need to double check 3 and 4. What I can tell you is that I don't think lifespan has to do with 3 or 4. I chose space and food simply due to the thought that more species moving to higher elevations allows for less space to live, but more prey to be hunted easier.)
Answer:
A. Yes, because the %A approximately equals the %T and the %G approximately equals the %C in both species.
Explanation:
According to Chargaff's rule, in all cellular DNAs, the number of adenosine residues (A) is equal to the number of thymidine residues (T). And the number of guanosine residues (G) is equal to the number of cytidine residues (C). Therefore, the sum of the purine residues equals the sum of the pyrimidine residues (A+ G= C+ T). It is based on the fact that a purine base always pairs with a pyrimidine base in a double helix DNA.
Chargaff’s rule is followed in all the double-helical DNA molecules irrespective of the species. In DNAs of sea urchin and salmon, the percentage of adenine is equal to that of the thymine and the percentage of guanine is equal to that of the cytosine. Therefore, Chargaff's rule is followed.
Answer:
Delivered small RNAs can inhibit protein A production through the RNA interference (RNAi) mechanism, and thus impairs angiogenesis
Explanation:
The pregnancy-associated plasma protein-A is a protease enzyme involved in the formation of new blood vessels by increasing insulin-like growth factor I (IGF-I) bioavailability. Moreover, small RNAs (<200 nucleotides in length, generally 18 to 30 nucleotides) are non-coding RNA molecules that function in RNA silencing through the RNA interference (RNAi) pathway. Small RNAs are widely used in molecular biology laboratories because they can be delivered into specific cells in order to silence target mRNAs such as, in this case, the mRNA encoding protein A, by complementary base pairing and thereby inducing translational repression. In consequence, mRNAs complementary to delivered small RNAs are silenced through RNAi pathways, i.e., by cleavage of the target mRNA and/or mRNA destabilization.
Answer:
Adding moisture to the waste in a suitably designed and operated landfill should increase its degradation, leading to less risk and a move towards sustainability. ... Proper aeration, moisture addition and gas extraction are needed to control the environment required for aerobic processes to thrive with optimum efficiency.

<u>TRUE</u></h2>
Explanation:
The eggs of a frog hatch into tadpoles, which look like little fish. After a few days, tadpoles develop legs and arms and grow into young frogs with tails. In the next few days, they grow into an adult frog with no tail. The process of growing from a tadpole to an adult frog is called metamorphosis
