Answer:
True
Explanation:
Point mutations arise when a single amino acid base is changed. This could cause some differences in the organism or it may not. Manufactured point mutations in model systems such as yeast offer a powerful tool to examine the function of different amino acids in a protein.
There are three types of point mutations
- Silent: these mutations have a single residue change but it does not affect the amino acid that is being coded. There is no change to the wild type
- Nonsense: will cause a stop or start or gain of start/stop codon.
- Mis-sense: will cause a change of amino acid residue. There are two types of mis-sense Conservative and non-conservative. The former will cause a change in amino acid base to one that has similar properties while the former will change to an amino acid of different properties often having different traits than the wild type.

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
The right option is; A. Solar
Solar energy is sustainable.
Solar energy is considered as a renewable energy resource. Solar energy is sustainable because it occurs naturally and it is derived from a source that is inexhaustible (sun). It can be depended on for the long term. All renewable energy sources such as geothermal, wind, biomass and hydro are sustainable.
