Answer:
b. trade winds (or tropical easterlies)
the ones located on the north and south poles are the polar easterlies and the one in between is the prevailing easterlies.
Answer:
social facilitation
Explanation:
The concept of social facilitation was first proposed by Norman Triplett. After observing a cycling event, in which he noticed that cyclist performed better when they have others around competing with them, rather than cycling alone just against time. This led him to duct an experiment where he gave some children strings to wound fishing reel. He observed that, children wound the fishing reel faster in the presence of other children performing similar task, when compared to when perform such task alone.
This concept discovered by Norman Triplett, best illustrates the concept of social facilitation, which posits that, individuals tend to perform better in the mere presence of others or when they perform a task with others, than when performing the task alone.
The global distribution of organisms and the unique features of island species reflect the evolution and geological change. Fossils. Fossils document the existence of now-extinct past species that are related to present-day species.
Osmosis is the answer. The molecules move
Answer:
approximately 150 amino acids
Explanation:
Proteins are produced from genes via a process called gene expression. In this process, the gene-containing DNA is first transcribed into mRNA molecule, which is subsequently translated into an amino acid sequence that makes up the protein molecule.
However, during the translation process, the mRNA molecule is read in a group of three nucleotides called CODON i.e. a codon is made up of three nucleotide/nitrogenous bases. Each codon codes for a particular amino acid.
Since one codon of a mRNA that is three (3) nucleotides long codes for one amino acid, hence, strand of mRNA that is 450 nitrogenous bases long will produce a protein containing approximately (450/3) = 150 amino acids.
