Which of the following is the amino acid that appears at the N-terminus of all newly translated prokaryotic and eukaryotic polyp
Elis [28]

Answer:

The correct answer is option second - methionine.

Explanation:

During translation, the initiator tRNA binds with a smaller subunit of the ribosome and this assembly bind to the start codon AUG at mRNA molecule in both prokaryotes and eukaryotes and then large subunit bind to this assembly and start polypeptide chain.

So, the first codon is AUG which is start codon and code for methionine in eukaryotes and fMeth in prokaryotes at newly translated prokaryotic and eukaryotic polypeptides at the N- terminus.

Thus, the correct answer is option second - methionine.

There is consensus among scientists that humans are causing the climate to warm. Why might this warming impact biological produc
MrMuchimi
The answer is: "<span>Warming may slow or halt the formation of cold dense water in polar regions, reducing the delivery of nutrients to depth, and thereby reducing productivity in deeper zones."

Global warming is caused by the accumulation of greenhouse gases in the atmosphere primarily by human activity. These increases the temperature in the polar regions will warm the water (and subsequently halting the formation of cold water). The melting of ice will release nutrients and stimulate the growth of phytoplanktons, and these organisms will compete with the nutrition in the deeper zones (the phytoplanktons and algae will reduce the available nutrients for deep sea creatures) and therefore decreasing the productivity.</span>

Examine the two waves shown below. Which wave has a greater amplitude
alexandr1967 [171]

Answer:

"Wave A" has the most amplitude.

Explanation:

Amplitude is defined as "the maximum extent of a vibration or oscillation, measured from the position of equilibrium."

"Wave A" appears taller, extending outwards from its center more than "Wave B", so your answer would be "Wave A".
