It would be 2. it emits all wavelengths in the electromagnetic spectrum
I think the correct answer is ions.
An action potential occurs when a neuron sends information down an axon, away from the cell body. A neuron that emits an action potential, or nerve impulse is said to fire. These action potentials are generated by special types of voltage hated ion channels that are embedded in the plasma membrane of the cell.
Im pretty the correct answer is stinging cells
Answer & Explanation:
All archeas are single-celled organisms, and despite having prokaryotic cells, there are both similarities and differences between archaea and bacterial cells and also with eukaryotes.
Archaea have only one cell that has no nucleus or real organelles, and its cells have membranes composed of branched lipids, which greatly alter the structure of the archaeal cell membranes. In addition, the archaea have only one DNA strand (uniqueness).
Animal cells differ from archeas because they are multicellular (organisms with several cells), each one having a nucleus, and they also have specialized organelles.
In addition, animal cells have compounds called phospholipids in their membranes, which are unbranched lipids, and therefore do not cause major changes in the structures of their cells. Finally, animal cells have double-stranded DNA (complementary duplication).
<span>The answer should be 67.5gram
If Mary wants to consume 15% of her kcalories from protein, then the target calorie would be: 15% * </span><span>1800 kcal= 270kcal.
Every gram of protein will give about 4 kcal of energy. So, the protein needed in gram would be: 270kcal / (4kcal/gram)= 67.5 gram</span>
