Answer:
b. they use the same set of nucleotides.
Explanation:
All the organisms use same set of nucleotides to specify an amino acid during translation because genetic code is universal. Genetic code which is a unit of genetic code is made up of various codons which are in turn a sequence of three nucleotides. Some of the examples of codons are AUG, CCG, UCG etc. Same codon specifies a particular amino acid to be incorporated into a peptide chain in all the organisms. For example, AUC specifies isoleucine in all the organisms of this earth including humans, plants, bacteria etc.
Answer:
The primary function of red blood cells is to transport oxygen to body cells and deliver carbon dioxide to the lungs.
Explanation:
All of these models apply to the scenario equally well.
Explanation:
- Firstly, the male crabs battle each other for territory using their greatly enlarged claws. This clearly depicts male-male competition.
- Secondly, Females choose to mate with only those male who are fit to survive in stress full condition. Thus female look for good genes that would enable her offspring to survive in stressful condition. Here Good gene mechanism applies.
- Thirdly, The presence of large claws make it more noticiable to female and stronger to compete with other males. Thus this is a direct benefit.
- Lastly, we see that female crab have a tendency to look up for their prey and this tendency is well exploited by male crabs who raise their claws to a heigh so that they get noticed by the female.
