Explain the production pathway used by cells to make the PSEN1 protein. Start with DNA and end at the plasma membrane. Mention some or all of the following cell parts in your explanation: rough endoplas- mic reticulum (RER), smooth endoplasmic reticulum (SER), lysosome, cytoskeleton, nucleus, ribosomes, mRNA, DNA, Golgi apparatus (GA), transport vesicles, mitochondrion, chloroplast, cell wall, plasma membrane. Hint: organize your explanation in steps, i. e. Step 1: DNA in the nucleus. . .

List two new traits (structural or behavioral) that each new species of rat might demonstrate as it adapts to the conditions on two of the four islands. choose only two islands that are described in the lesson. record the island latter and the major habitat feature of the island. then list two new traits each rat subspecies might demonstrate in order to survive the habitat on that island. note: new traits should be unique to that island and be in response to that island’s habitat feature. i cannot remember islands that were names in the lesson so only answer if you have done the lesson (5.13 life science 7b) choose 2 of the islands and describe a structural and a behavioral trait for a rat on each island so 4 total answers, 2 different structurals and 2 different behaviorals, one for each rat for each island

There are specialized producers that live in warm water vents deep in the ocean. these producers do not per-form from photosynthesis, but instead perform a similar process with iron and other chemicals. why do you think these producers use this process instead of photosynthesis?
