Aerobic respiration happens in the mitochondrion of eukaryotic cells.
Anaerobic respiration does not use oxygen gas and happens in one process after glycolysis called Fermentation.
The process used to make beer would be a kind of fermentation, Alcohol fermentation, I believe.
The genetic code defines how codons, sequences of nucleotide triplets, specify which amino acid will be added next during process of translation (protein synthesis).
The genetic code is universal among organisms. That means that the same codons code for the same amino acids in different organisms.
It is known which amino acids are coded by which codons. If we know sequences of amino acids, we then also know sequences of nucleotides in DNA/RNA. If we know DNA/RNA sequences we can then reveal relationships among different organism by compering similarities in those sequences.
An open fracture is most accurately defined as a fracture in which the overlying skin is no longer intact. A fracture is normally the break in the continuity of the bone. It is also called a compound fracture, in which the fracture is an open wound or break in the skin near the site of the broken bone. Immediate treatment for an open fracture focuses on preventing infection at the site of the injury.
Answer:
1. Potassium
2. increasing towards zero
3. hyperpolarization
4. voltage-regulated Potassium
Explanation:
Membrane potential can be defined as the difference in electric charges inside and outside of a cell. The resting membrane potential (RMP) occurs when there is no net current across the membrane and therefore the cell is in a non-excited state. At the RMP, sodium ions (Na+) are more concentrated inside the extracellular fluid (ECF) than inside the intracellular fluid (ICF), while potassium ions (K+) are more concentrated inside the ICF. The diffusion of K+ outside the cell triggers its hyperpolarization, by becoming the membrane potential more negative compared to the resting potential. As the potential nears +35 mV, the voltage-regulated potassium channels are open, thereby K+ ions leave the cell down its concentration gradient, while voltage-gated Na+ channels become saturated and inactivate.
Sex chromosomes determine one's gender. Of the 23 chromosomes humans have, one of the pairs are sex chromosomes. Autosomes make up 22 pairs of the chromosomes. They determine other traits of the body like hair color, eyes, or skin.
