Answer:
Breathing out the carbon dioxide
Explanation:
Blood is the medium through which carbon dioxide is transported to the lungs from where it is exhaled out.
The Carbon dioxide produced in cells after respiration diffuses into the blood in exchange of oxygen delivered to the cells for further respiration. Blood while flowing through the lungs passes carbon dioxide to its alveoli which is then exhaled out and oxygen is inhaled from outside.
Hence, cell keep the carbon dioxide from building up in the cytoplasm and poisoning the cell by exhaling CO2.
Answer:
Neurotransmitter
Explanation:
A neurotransmitter is a signal which transmits information between neurons at the end of the axon. This neurotransmitter can either be excitatory or inhibitory. Whenever an action potential is triggered within a neuron, the neurotransmitter releases this action potential into the synapses at the axon as either an excitatory or inhibitory signal before a new action potential is triggered.
Derived characteristics refers to those traits that have changed from ancestral form or function. The derived character, which cause K. monera to be divided into K. archeabacteria and K. eubacteria is that genetically and biochemically the two are different. The archeabacterial possess unusual lipid, which is not find in eubacteria or any other organism. And this give it the capacity to live in extreme environments.
It is a perfect example of a natural selection.
