The large majority of spiral galaxies are flat, rotating disks. Within the disk, there are stars, dust, and gas. The disk also contains spiral arms and a central concentration of stars known as the bulge of the galaxy.
Answer:
<h2>
1. Protein synthesis on attached ribosomes:</h2><h2>Destination: cell membrane.
</h2><h2>One general function
: to be a surface receptor.</h2><h2>2. On free ribosomes- destination: cytosol
</h2><h2>One general function: microfilaments.</h2>
Explanation:
Proteins are synthesized by the process known as translation. Translation occurs by ribosomes as they can be attached with endoplasmic reticulum or they can be free in the cytosol.
Protein is synthesized according to the sequence of nucleotide on mRNA.
Newly synthesized protein contain signals sequence which targets then for their final destination.
1. ONE ultimate destination of a protein produced on an attached ribosome: These proteins, after synthesis enter into ER and then according to the signal sequence, they reach to their final destination.
Example: cell membrane.
One general function of the protein
- to be a surface receptor
2. One ultimate destination of a protein produced on a free ribosome: cytosol
One general function of the protein: microfilaments
I believe the correct answer from the choices listed above is the last option It is Joseph Proust's law about the ratios of masses of elements in a compound did John Dalton’s work on the atomic structure help to explain. <span>Dalton's law of multiple proportions is part of the basis for modern atomic theory, along with </span>Joseph Proust's<span> law of definite composition. Hope this answers the question.</span>
