Answer:
D. Many amino acids are encoded by multiple codons. A gene mutation that encodes the same amino acid would have no observable effect on the cell or the organism
Explanation:
If gene mutation does not change code (gene still encodes for the same amino acid), the same protein with its function will be produced. This is called synonymous mutation.
Silent mutations might also occur when codon is altered to produce an amino acid with similar function as previous (e.g. leucine to isoleucine) so that the function of protein is not significantly changed.
I think the answer is <span>epithelial and connective tissue
Muscle cells need much energy to moves its fiber, so it must be on a highly vascularized area. The nervous system also needs a blood supply to works. In fact, the brain cells use the highest amount of energy.
Epithelial and connective tissue doesn't need much energy because its main function is to protect other tissue. It also has densely packed cells to make it sturdy.</span>
The sign of lead poisoning in children would be impaired development.
Lead is very toxic to the brain, so lead poisoning will be especially dangerous in children when the brain is developing at a high rate. Damage to the brain will cause the children to have an impaired development and growth, gastrointestinal pain, or neurological issue like seizure.
The blue visible light waves have a shorter wavelength than the red visible light waves. Since both the waves travel at the speed of light, which is a constant for a particular medium, their frequencies will be inversely related to their wavelength. This is given by the formula: speed = wavelength x frequency. Thus blue visible light will have a higher frequency than the red visible light.
