Polylysine and polyglutamate are two examples of synthetic polypeptides that can assume an α‑helical structure under appropriate conditions. identify which two synthetic polypeptides can form an α‑helix at the indicated ph values. polyglutamate at ph 13ph 13 polyglutamate at ph 2ph 2 polylysine at ph 2ph 2 polyglutamate at ph 7ph 7 polylysine at ph 13ph 13 polylysine at ph 7

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
