In a DNA molecule, three nucleotides make up a codon. A codon is creates a specific amino acid. Therefore, in order to work this out, we must calculate the number of codons that will not be affected by the mutation. This is done by finding the highest number that is divisible by 3 but less than 85. This can be done by:
85 / 3 = 28.333
So 28 codons will not be affected.
Answer: So whats your question?
D, light can travel in the air or a vacuum and the speed is constant whether the light source is stationary or moving.
Answer:
I’m concerned about how the dam will affect the water flow in the river, which can affect the behaviors of fish. I’m also concerned that some fish and aquatic animals might get sucked into the dam. Finally, I worry that the dam could malfunction and cause flooding, which could damage the ecosystem.

Answer:
The cell interior would experience higher than normal Na+ concentrations and lower than normal K+ concentrations.
Explanation:
The Na/⁺K⁺ pump is an ATPase pump which is responsible for maintaining low Na⁺ and high K⁺ concentrations within the cytoplasm while maintaining high Na⁺ and low K⁺ concentrations in the extracellular fluid.
Since these two ions are moved against their concentration gradient, ATP hydrolysis is required to provide the energy for this process. This is done by moving in two K⁺ ions inside while moving three Na⁺ ions outside the cell for every molecule of ATP hydrolysed to ADP and Pi.
If a competitive non-hydrolyzable analog of ATP is applied on the cytoplasmic side of a plasma membrane that contained a large concentration of the Na/⁺K⁺ pump, it will act by inhibiting the action of the Na/⁺K⁺ pump. This will result in an accumulation of Na⁺ ions inside the cell and lower than normal K⁺ ions concentration.
