The correct answer is S phase
Answer: B and D
Explanation: We can break down why the correct answers are choices B and D by understanding why A and C are incorrect.
Option A states that active transport utilizes channel proteins, and facilitated diffusion utilizes carrier proteins. This is incorrect. Active transport involves carrier proteins, and facilitated diffusion involves channel proteins. Carrier proteins are different from channel proteins in that, while channel proteins can only facilitate the passive diffusion of ions into or out of the cell along their concentration gradient, carrier proteins can also use ATP to move ions in or out of the cell against their concentration gradient.
This brings us to why option C is also incorrect. Option C states that both processes require the input of energy in the form of ATP. While active transport requires the use of ATP to transport ions with or against their concentration gradient, facilitated diffusion does not. This is easily remembered when we consider that active transport is called *active* transport because the cell is *actively* using energy to transport ions.

We know that fertilizier could promote the growth of the plant
When washed to the river, it will accelerate the growth of the water plant that exist within that area,
This occurrence will be not beneficial to the water animal because their habitat will be unnaturally blocked by these plants

Hi There! :)
<span>What amino acid is carried by tRNA with anticodon, GUA?
</span>The mRNA sequence that you have shown above has been given in triplets of bases. These triplets are called codons. Therefore the amino acid that tRNA will bring must be complementary to this hence called the anticodon. There is a rule. A always pairs with U (or T if it was a DNA strand) and C always pairs with G.
<span>For the first two triplets I will do the anticodon sequence then you can finish off : GUA GCC ..... </span>
<span>Each codon or anticodon triplet codes for an amino acid. To find this out published tables are used. All the possible triplets will be on there. You will simply just have to read off the names of the amino acid stated next to it in that grid table. </span>
