Answer:
You need homeostasis to survive. Homeostasis is what warms up your body when your body's core temperature lessens. It also cools you down when you are very hot. For example, when you are very hot your body will release sweat particles to cool you down. Without homeostasis you would suffer from hypothermia or heat stroke at a higher probability.
Explanation:
Answer:
Because of different abiotic factors (Temp, humidity, ect.)
No there is no selective pressure that confers an advantage to those who do taste it.
<h3>What is PTC?</h3>
Despite the fact that PTC isn't found in nature, tasting other bitter substances—many of which are toxins—that do occur naturally has a high correlation with taste sensitivity.
In order to defend themselves from being eaten, plants develop a range of harmful substances. Early humans developed the capacity to distinguish bitter tastes as a safeguard against ingesting dangerous plants. There are roughly 30 genes in humans that produce bitter taste receptors. People may taste a large variety of bitter substances because each receptor can interact with a number of different molecules.

Answer:
Ribosomes,cytoplasm ,cell wall and circular DNA could be used to justify that the cell is a prokaryote.
Explanation:
Ribosome Ribosome is present in both prokaryotic cell and eukaryotic cell.The prokaryotic cell 70S ribosome which contain 2 subunits the larger subunit is 50S and the smaller subunit is 30s
Cell wall Prokaryotes such as bacterial cell contain cell wall.Cell wall of bacteria contain various carbohydrates which are crosslinked with peptides resulting in the formation of peptidoglycan.
Cytoplasm The cytoplasm of prokaryotic cell such as bacteria contain ribosomes,chromosome and extracellular genetic material called plasmid.
Circular DNA Almost all prokayotic chromosome contain circular DNA molecule that does not contain any free ends.
Bottleneck is the term used to define chance changes in the frequency of alleles which have a significant effect on small populations. The effect is that the population is greatly reduced because of the change in the allele frequency. A genetic drift will follow which will expedite evolution.
