Answer:
True.
Explanation:
in the early 1900s development of Salvarsan, an arsenic-based drug to treat syphilis.
The process that tend to reduceb the variety within a population is called B. Random fertilization.
Answer:
(b) - False
Explanation:
Prochlorophyte bacteria are photosynthesizers and have the same chlorophyll found in algae and vegetables, studies claim that these bacteria are the most abundant beings on the planet, accounting for half of all photosynthesis performed in the oceans.
Prochlorophyte bacteria can be divided into <em>Prochloron</em>, <em>Prochlotrix</em> and <em>Prochlorococcus</em> genera.
However, <u>prochlorobacteria</u> are not responsible for the production of dairy products, in which the most associated bacterial genera are <em>Lactobacillus</em> and <em>Streptococcus</em>. This last statement implies that alternative b is the correct one.
Answer:
This question lacks options, however, it can be answered based on general understanding of the topic
The answer is SUBSTITUTION MUTATION
Explanation:
A mutation is any change that occurs in the nucleotide sequence of a gene. Mutation can be of different types depending on how it occurs. One type of mutation is SUBSTITUTION MUTATION, which is a mutation in which one or more nucleotide base is replaced by another in the sequence.
Nucleotide bases are read in a group of three called CODON. Each of these codons specify amino acid. Hence, if the nucleotide base sequence is altered during mutation, the amino acid sequence is altered likewise. In this case where the original amino acid sequence is: Met-Ala-Gln-Arg-Glu-Leu, the mutation affected the nucleotide bases coding for Arginine (Arg), hence changing it to Glycine (Gly).
This means that a base substitution mutation occured, replacing the amino acid Arginine with Glycine in the mutated sequence.
