Answer:
produces offspring genetically identical to the parent
Explanation:
Incorrect statement is: Type II membrane proteins have a signal sequence targeting them to the ER as well as a signal anchor sequence.
Signal peptide or signal sequence is a sequence of amino acids that gets recognized by signal recognition particle (SRP). This sequence is involved in cotranslational translocation into ER, where the protein should be folded. A stop-transfer sequence signals that translation of the protein should continue in the cytosol (not in ER). A signal anchor sequence signals the insertion of protein into the ER membrane.
Antarctic fish species requires an adaptation to cold environment. Living at cold temperature environment would demand certain biological responses such as cutaneous respiration, enlarged blood vessels, and producing greater amounts of fat. Most of these fat are composed of higher phospolipid levels which are primarily due to phosphatidylethanolamine. This phospolipid is responsible for destabilizing cell membranes and make it more fluid thereby allowing unrestricted blood flow. The fatty acid composition of the membrane lipid is important for membrane fluidity, this is mainly attributed to unsaturated fatty acids which are responsible for decreasing the order of membrane lipids thereby decreasing viscosity. At extremely low temperatures, organisms with low concentration of unsaturated fatty acids would freeze cell membranes. That's why antarctic fishes have higher levels of unsaturated fatty acids.

Two questions have been asked, and responded to
Answer:
For question 1: The statement is true
For question 2: Yes, the two wild roses are of the same population
Explanation:
Population is simply the total number of organisms of the same species LIVING and BREEDING together in a given area.
I) To be considered part of the same population, two of more organisms MUST BE able to mate i.e produce gametes that are viable enough to fuse together and create new offsprings.
2) Yes! Two wild roses separated by a wide road belong to the SAME POPULATION because
- it is still a given area or habitat
- transfer of pollen grains by agents such as wind or insects is possible, thus breeding still occurs.
