b. cell x because it has chloroplast.
During complex and demanding tasks, teens distribute the workload evenly throughout the brain. In teenagers the prefrontal cortex is still developing and therefore they may rely on a part of the brain called the amygdala to make decisions and solve problems more than adults. The prefrontal cortex communicates with other sections of the brain through connections called the synapses.
Answer:
6, 3, 4, 5, 7, 2, 1
Explanation:
Here, speciation occurs because the original butterfly population gets separated into two populations, each facing a different set of environmental conditions. Initially, there was just a single population of butterflies in the valley and all butterflies were able to mate with each other. A fire destroyed their habitat so they had to migrate to other areas. Some butterflies migrated to eastern side of mountain and some to western side of mountain.
Now there were two butterfly populations and they faced different environment from each other. Over the time, the populations adapted to their local surroundings and started to accumulate changes in their genome. Their gene pools started to separate from each other. Eventually they evolved into two different species. When their old habitat was restored in the valley, they returned once again. However, this time they were not able to interbreed because they were now two different species.
Answer:
The production of peptides linking aminoacids through peptidic bonds
Explanation:
Chemically, peptides are synthesized by condensation where the carboxyl group of one amino acid is linked to the amino group of the other amino acid. The most common way to make a chemical peptide synthesis is linking first the carboxyl end of one amino acid to the amino group, not in the other direction. The opposite reaction, starting from the amino end and linking to the carboxyl end, is made in biosynthesis made by living organisms.
