Answer:
The correct answer is option e. "result in permanent activation of Ras".
Explanation:
Ras function is regulated by the GTP/GDP cycling rate, in a way that Ras is inhibited by the substrate GDP. Once Ras hydrolyzes GTP, GDP is produced and Ras is inhibited by GDP. A mutation that inhibits Ras from hydrolyzing GTP, would lock Ras in a permanently activated state because no GDP would be produced and there will be no substrate to inhibit Ras.
Answer:
<h2>D. Animals </h2>
Explanation:
Animals are a member of kingdom. Animals all living things alive are animals except for plants and microorganisms.
Protists is a free-living or colonial organisms with diverse nutritional and reproductive modes.
Fungi is the taxonomic kingdom of lower plants.
Plants is a factory that produces power or where industrial items are made. A living thing with roots and usually a stem and leaves, growing above and below the ground. Place a plant or the seed of a plant into the ground so that it will grow.
Therefore, the final answer is d. Animals.
Answer: D. increase surface area
Explanation:
- Microvilli are hairs that aid in absorption of nutrients. In the small intestine, these cells contain microvilli, which are tiny hair-like projections that increase nutrient absorption. These projections increase the surface area of the small intestine allowing more area for nutrients to be absorbed.
When the concentration o molecules inside a cell is different form the concentration of molecules outside a cell, we can either call it hypertonic or a hypotonic solution, and the difference between the two concentrations is called a concentration gradient.
Hypertonic - name given to a solution that has a bigger concentration than the concentration in a cell.
Hypotonic - name give nto a solution that has a smaller concentration than the concentration in a cell.

Answer
Only one type of amino acid could be coded for such synthetic mRNA, becacuse it contain only one type of codon.
