This is an example of vestigial structure.
Vestigial structures are structures (cells, tissues and organs) found in an organism that has lost most or all of its primitive function through evolution. The vestigial structure has performed vital functions in the organism in the past but as there are changes in species as a result of natural selection, the structure became less important until it no longer functions. A reduced nonfunctional digit on the paws of dogs known as a dewclaw is an example of vestigial structure.
<span>1.
They are the sites of reactions that convert solar energy -> chemical energy.
2.
They contain the green pigment chlorophyll.
3.
They have membranous sacs called "thylakoids" that are surrounded by a fluid called "stroma".</span>
Answer: Regulation of activity by higher brain centers.
Explanation: The autonomic nervous system is part of the peripheral nervous system and is responsible for involuntary actions that occur without control, such as breathing and heart rate.
The somatic nervous system is also part of the peripheral nervous system but is responsible for the transmission of signals to the skeletal muscles and from receptors of external stimuli.
The peripheral nervous system regulates systems such as the nerves and ganglia that are found outside of the brain and spinal cord. Thus the autonomic and somatic nervous systems differ, but both are not involved in the regulation of activity by higher brain centers.
Answer:
The inheritance pattern of these traits will be independent. However, it will depend on the factor that which trait is dominant or recessive. It might also show incomplete dominance.
The different genotypes that organisms of this population might have are aa, ab, ac, bb, bc , cc. If neither of the alleles are completely dominant over the other, then incomplete dominance might exist for such genes.
MRNA is the RNA that assists in Messaging the DNAs instructions to the ribosomes (sites of protein synthesis). tRNA helps to transfer the necessary amino acids to the ribosomes. In short, mRNA tells the ribosomes what amino acids to use and in what order. tRNA “retrieves” those and bring later them to the ribosomes.
