c. a spiral galaxy
d. an elliptical galaxy
Answer:
c. spiral galaxy
Explanation:
the image
The reason it could not be a galactic supercluster is because a galactic supercluster is made up of small galaxies, and the Milky Way is part of the Virgo Supercluster. It is part of a supercluster but is not a supercluster itself.
Answer:
a galactic supercluster
Explanation:
Answer:
chemical nature of the membrane
Explanation:
The cell membrane is bilayer of amphipathic phospholipids and proteins The hydrophobic tails of phospholipids make the inner core of the membrane while hydrophilic heads are oriented towards the surface of the membrane.
The membrane is selectively permeable as it allows only nonpolar, small and uncharged substances to pass through its hydrophobic inner core. Hence, the chemical nature of the membrane makes it choose the allowed substances to be transported.
The correct answer is - A. A mutation that causes the code for the wrong amino acid.
The missense mutation is a type of mutation that affects the amino acids of the organisms. This mutation results in a codon that codes a different amino acid rather than the one that should be coded. Because of this it causes a synthesis of a protein with altered amino acid sequence during translation. This type of mutation is basically a change in one DNA base pair that results in the substitution of one amino acid for another one.
The right choice is (A) mutation that causes the code for the wrong amino acid.
In cell biology during when a missense mutation occurs in a DNA molecule, it varies in one of the RNA codon sequences which are made during transcription. The difference produced in codon will then cause a different amino acid to be inserted into a protein during translation process so we can say that a missense mutation is a point mutation in which a single nucleotide change results in a codon that codes for a different amino acid
