C. the making of an RNA molecule from a DNA strand by pairing of bases of RNA nucleotides with the complementary bases in DNA
Answer: 1, 3, 5, 2, 6, 4
Explanation:
The sympathetic nervous system stimulates many parts of the body for action during times of danger.
This signalling starts when the postganglionic neuron depolarizes, and postganglionic neuron releases acetylcholine, then the acetylcholine binds to nicotinic receptor in order to transmit impulse, and further the acetylcholine binds to sweat gland’s muscarinic receptor to disrupt or inactivate the action of acetylcholine. Finally, the neuron releases acetylcholine, and the neuron exits lumbar segment of spinal cord.
The danger has now been fully interpreted.
Answer:
B.
Explanation:
ETS or electron transport chain is the last stage of aerobic cellular respiration that leads to the formation of a huge amount of adenosine triphosphate also known as ATP which is the energy currency of the cell.
It occurs in the inner mitochondrial membrane. Electrons are passed through various protein complexes present in the inner membrane of mitochondria.
As electrons pass through the electron transport chain, electrons move from a higher to a lower energy level and are ultimately passed to oxygen.
During this process, Energy release in the electron transport chain is trapped as a proton gradient. Due to this concentration gradient, ATP synthase is a final protein complex, forms ATP.
British naturalist Charles Darwin is credited for the theory of natural selection. While he is indeed most famous, Alfred Wallace, simultaneously came to a similar conclusion and the two corresponded on the topic. change in heritable traits of a population over time.
Hope this helps!
