Answer:
Explanation: Scientists attempt to order the natural world by grouping and classifying all living organisms. As technologies improve, so have our systems of classification. ... This is the process of “natural selection” and causes the many species of organisms on Earth to change over time
Nicked circle is the reason.
Explanation:
During recombinant DNA technology the gene of interest is ligated to plasmid DNA by excision with molecular scissors or endonuclease enzyme and ligated with enzyme ligase.
Enzyme ligase catalysed by ATP seals the nicks by making phosphodiester bonds in the ds or ss DNA and release of ADP.
The ligation in the plasmid did not occur properly hence the replication is interrupted hence no new plasmids with gene of interest replicated in the ligation carried out.
This answer to this question is Paramecia, cilia
Answer:
For involuntary actions (reflexes) the information is first detected in the sensor and travels along sensory neurons to the spinal cord. Once the action potential reaches the spinal cord, the information is transmitted across the synapse to the motor neuron. for voluntary actions,
movements are commanded by the motor cortex, the zone of the cerebrum located behind the frontal lobe. The motor cortex sends a neural message that moves through the brain stem along the spinal cord and into the neural network to the muscle being commanded.
