There you goooo! Good luck
Answer:
A.
Explanation:
Passive transport is defined as the movement of ion and other molecules through cell membrane without any energy input while active transport is the movement of ions and other molecular substances across cell membranes with an energy input which allows, molecules to move from a region of lower concentration to a region of higher concentration.
Uptake of iodide ions by thyroid cell is an active transport which is mediated by sodium/iodide symporter (NIS) protein, found in basolateral membrane of thyroid follicular cells. As the concentration of iodide ions is higher in thyroid cells, active transport make movement of iodide ions form extracellular fluid (lower concentration) to thyroids cells (higher concentration).
Hence, the correct option is A.
The answer is "it begins releasing the enzymes to break down large molecules
Some mutations don't have any noticeable effect on the phenotype of an organism.This can happen in many situations: perhaps the mutation occurs in a stretch of DNA with no function, or perhaps the mutation occurs in a protein-coding region,but ends up not affecting the amino acid sequence of the protein.
1. is C. because the furthest humans have traveled in space is to the moon.
2. is true, as long as the spacecraft has some repairs, because the heat will cause some damage to the exterior.
3. is C. because unmanned spacecraft have successfully landed on mars, while manned spacecraft have only made it to the moon, so far.
