They were adapted to an environment and once it is taken away the plants will slowly start to die. I'm not 100% :)
Answer:
The vision remains unaffected.
Explanation:
Rods and cones are two types of photo receptor cells present in the organism. Cone cell helps in the visualization of color whereas rod cells are involved in the light intensity.
The cat was stuck in the neighbor's cellar with enough food and water. The cat was stuck in the basement with pitch-black but this does not affect the vision of cat. Cats are nocturnal animals and has large amount of rod cells that enable them to see at night. Thus, her vision remains unaffected.
Answer:
A point mutation can be described as a mutation in which changes occur in a single nucleotide. A nucleotide may get changed, deleted or inserted from the sequence of DNA. Point mutations can be harmless or harmful depending on the nucleotide in which the changes occur.
A change in just one nucleotide can result in the formation of wrong amino acid and hence changed or wrong proteins can be formed. If the original protein was involved in cellular reproduction, then the entire process of reproduction can be affected by a point mutation.
Sickle- cell anaemia is a disease in which the body fails to produce enough healthy red blood cells. This disease occurs due to point mutation. Point mutation occurs where glutamine (GAG) of the β-globin gets changed into valine (GUG). This change causes the haemoglobin to get a deformed structure due to which it is not able to carry out oxygen.
