<span>Birds and dinosaurs show homology because they are closely related, such as pigeon and tendon. They have different types of wings, but birds have evolved from dinosaurs. Unlike other species such as insects, which can be a homoplasy or a homology. This is due to its world and complexity.</span>
Drinking water shortages? Water across the world isn't purified which without purification doesn't quench thirst.
Answer: No
Explanation:
the freezing point of salt water is lower than that of pure water, due to the presence of the salt dissolved in the water
Answer:
Could be multiple. C or A
Explanation:
Enzymes are required for respiration and respiration is exo thermic
A mutation which occurs when a base is introduced into the DNA sequence before transcription begins will lead to frame-shift of a single base on the DNA sequence resulting in nonfunctional protein from the transcribed mRNA.
Explanation:
This change either through addition or deletion of a single base in the codon sequences of the DNA will modify the amino acid codes and will result in nonfunctional proteins after transcription.
This mutation will just result in change of a single base, i.e., it would be added either to the enhancer region or the silencer region of the sequence before the promoter which initiates transcription.
The mRNA produced due to mutated DNA sequence after the deletion or insertion point will be read as out of frame thus resulting in nonsense protein.
