Answer:
A dolphin's flipper, a bird's wing, a cat's leg, and a human arm are considered homologous structures. ... Bats, whales, and many other animals have very similar homologous structures, demonstrating that these creatures all had a common ancestor
Just don't worry about the human part
hope this helps
Answer:
A. Aerobic respiration
Explanation:
The cell body of neurons have mitochondria which in turn serve as the site for ATP production. Nerve cells derive their energy by complete oxidation of glucose by the process of aerobic respiration. The enzymes required for aerobic respiration of glucose are present in mitochondria. The ATP molecules produced in cell bodies are delivered to the other parts of neurons to serve as source of energy during conduction of nerve impulse.
If you give me the rest of the question maybe I can help?
Answer:
1. It could result in a loss of function of the protein product
2. It could result in a protein product with excessive activity
3. It could result in altered structure of the protein
Explanation:
Any changes that occur in the nucleotide sequence in the DNA of an organism is known as a mutation. Various forms of mutation can occur in the DNA sequence of an organism which could be as a result of insertion or deletion of a nucleotide in the DNA sequence.
Insertion of an extra nucleotide into a DNA strand within a gene could have any of the following effects on the protein protein;
1. It could result in a loss of function of the protein product of the gene whereby the protein can no longer carry out its normal functions
2. It could result in a protein product with excessive activity other the normal range at which it functions.
3. It could result in altered structure of the protein either in the primary, secondary, tertiary, or quaternary structure
