Answer:

Platyhelminthes

Explanation:

Platyhelminthes (phylum Platyhelminthes), also known as flatworms, are bilaterian, unsegmented and soft-bodied invertebrates. Platyhelminthes are hermaphroditic organisms with internal fertilization. In addition, this group shows a series of characteristics including 1-a ladder-like nervous system, 2-presence of parenchyma in the body cavity, and 3-flame cells, i.e., specialized excretory cells that function like a kidney. Platyhelminthes can be divided into three groups: Turbellaria (generally found in freshwater), Trematoda (generally parasitic), and Cercomeromorpha (exclusively parasitic).

rewona [7]

Answer:

Electron microscope would be used for if,

C) details of cell structures needed to be distinguished.

Explanation:

  • The general principal of electron microscopy is analogous to light microscopy except that it uses electrons to analyse the specimen instead of light.
  • Electron microscopy focuses a beam of electron on the target sample and records the difference in absorption by different surfaces.
  • Electron microscopy is used to get the detailed structure of cells and surface features of various viruses and bacteria.
  • However, it is not possible to view living biological samples through electron microscope because high velocity electron have immense energy to kill living cells.
  • These samples are thus, fixed and then viewed.

A mutation in a polypeptide with the original amino acid sequence of: Met-Ala-Gln-Arg-Glu-Leu results in a mutant with the seque
Nezavi [6.7K]

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.
