<span>A stem is one of two main structural axes of a vascular plant, the other being the root. The stem is normally divided into nodes and internodes. The nodes hold buds which grow into one or more leaves, conifer cones, roots, other stems, or flowers (inflorescences); the internodes distance one node from another.</span>
I believe the answer is C.
The important point is that the surface area<span> to the </span>volume ratio<span> gets smaller as the </span>cell<span> gets larger. Thus, if the </span>cell<span> grows beyond a certain </span>limit<span>, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular </span>volume<span>.</span>
Creatine, Caffeine, Branched-chain amino acids and Beetroot juice.
Creatine:
- Athletes frequently utilize creatine to enhance performance in weightlifting or sprinting. It might help with muscle healing and mass-building.
- Caffeine might increase mental clarity and lessen feelings of weariness.
- Leucine, isoleucine, and valine are branched-chain amino acids that may improve endurance performance by acting as a crucial energy source when carbohydrate levels are low.
- By increasing blood flow to working muscles, beetroot juice may improve athletic performance.
- By sustaining production in active muscles, creatine aids in ensuring a steady supply of energy to working muscles. Additionally, your heart, brain, and other tissues contain little amounts.

Answer:
is this it?
Explanation:
Cytotoxic CD8 T cells carry out their killing function by releasing two types of preformed cytotoxic protein: the granzymes, which seem able to induce apoptosis in any type of target cell, and the pore-forming protein perforin, which punches holes in the target-cell membrane through which the granzymes can enter.
