Maurinko [17]4 years ago

One example of how natural selection can change the distribution of a trait is the peppered moths during the industrial revolution. The moths were originally mainly white with a few black spots, however, when all the factories were built, the trees the peppered moths lived on turned a black color, causing ones who were mostly white to be picked off by predators, but the ones that were black with a few white spots survived and blended in better, leaving them to breed and produce more black-colored moths that would survive easily.  This shows the changing of a trait because ones that used to be mostly white were killed, showing a shift in the trait pattern in favor to the black moths that now lived instead of the white moths.

The polypeptide encoded by the glucose carrier gene has a signal sequence. As a result, the ribosome and the polypeptide that is
olganol [36]

Answer:

The correct words for the three blanks are as follows:

1. Endoplasmic reticulum. 2. Golgi apparatus. 3. Facilitated diffusion.

Explanation:

During the translation stage of protein synthesis, signal sequences are either attached or excluded from a synthesized protein in order to indicate the right location it should be sent to. Proteins that possess signal sequences are usually sent to the endoplasmic reticulum, where they will be folded into their right shapes. From the endoplasmic reticulum the proteins are then transported into Golgi apparatus via membrane vesicles. In the Golgi apparatus, proteins undergo their final modifications before they are transported to their final destinations. The final destination of glucose carrier proteins is the plasma membrane, where they help glucose molecules to enter the cell via facilitated diffusion.
