Answer:
d. Genes that play a role in the same metabolic pathway are organized into an operon.
Explanation:
In prokaryotic organisms like bacteria, polycistronic mRNAs exist which means that each gene does not have a separate promoter of its own. In fact many genes are under the control of a single promoter. These genes being a part of same metabolic pathway are organized into an operon. For example, lac operon and tryptophan operon. In lac operon, three genes named as β-galactosidase, permease and transacetylase are expressed under a single promoter which is known as lac promoter.
In contrast to this, in eukaryotes the mRNAs are monocistronic i.e. only a single gene is controlled under a single promoter.
Answer:The ear is divided into three main parts – the outer ear, the middle ear, and the inner ear. The inner ear is filled with fluid. The inner ear also contains the receptors for sound which convert fluid motion into electrical signals known as action potentials that are sent to the brain to enable sound perception
Explanation:
The left cerebellum shows decreased activity, and the right cerebellum shows increased activity when an individual is learning a mirror-reading task.
Body parts are moved by several regions of the cerebrum. While the right side of the brain directs movement on the left side of the body, the left side of the body is directed by the right side of the brain. The right hemisphere manages the left side of the body, while the left hemisphere manages the right.
The left hemisphere, for instance, has been found to be better at creating associations in memory, selective attention, and positive emotions. Contrarily, research has found that the right hemisphere performs better in terms of pitch perception, arousal, and negative emotions.
