Are you looking for the term for a chemical pollutant?
Answer:
50000
Explanation:
number of paramecium in 1 gallon of water = 50
number of paramecium in 1000 gallons of water =
1000× 50 = 50000
The right answer is 20 aminoacids per second.
Transcription is a mechanism for synthesizing RNA from DNA.
Translation is a mechanism for synthesizing a polypeptide sequence from mRNA by converting the nucleotide triplet (codons) to amino acids.
So if one amino acid corresponds to three nucleotides. The polypeptide synthesis rate should be 20 amino acids per second for 60 nucleotides per second.
3 nucleotides ==> 1 amino acid
60 nucleotides ==> 60/3 = 20 amino acids.
The answers are shown below:
In part A:
coefficient = 20
variable = c
constant = 35 & 23.50
In part B:
savings = 20 (3) +23.5+ 35+35+35 +35 +35 +35+35+35+35+35+35+35
savings = $ 503.5
In part C:
the new expression will be: 25c + 35 + 23.5
Answer:b) The air at high altitudes are less dense, so its harder to breathe.
Explanation:
AS altitude increases, the air pressure drops. This reduces the amount of gas molecules in the air so the air becomes less dense compared to air closer to sea level.
