Answer:
Firstly, the partial pressure of nitrogen (78%) is crucial to breathing purposes. Without this pressure, the lungs will burst and animals cannot survive.
Secondly, nitrogen is required for the formation of amino acids (building blocks of proteins) and other organic compounds that are necessary for the survival of living organisms. Principally, in the atmosphere, nitrogen is present in the form of molecular nitrogen (N2). N2 is fixed by nitrogen-fixing bacteria that form nitrates and nitrites. These molecules are then used in biochemical processes to produce proteins (amino acids) and other organic compounds. In the absence of nitrogen, these processes could become seize of limited significantly thus affecting life overall.
Thirdly, nitrogen and its derivatives act as greenhouse gases that maintain the Earth's temperature within a range that supports life. Yes, the increased abundance of nitrous oxides is not good because of acid rain and other issues, however, still, the presence of nitrogen is important for life on this planet.
Answer:
The correct answer is 3' UCA 5'
Explanation:
The rule of pairing of base-pair says that A and T base pairs with each other with two hydrogen bonds and G and C base pairs with each other with three hydrogen bonds in DNA. In the case of RNA Uracil comes at the place of thymine that means uracil replaces thymine.
Therefore according to this base-pairing rule the corresponding codon of mRNA transcribes from DNA codon 5' AGT 3' will be 3' UCA 5' as U came in place of A nucleotide, C comes in place of G nucleotide, and A comes in place of T nucleotide.
Therefore the correct answer is 3' UCA 5'.
Answer: The correct option is C (Dendrites, Cell body, Axon, Axon terminals)
Explanation:
The transfer of information from neuron to neuron takes place through the release of chemical substances into the space between the axon and the dendrites. These chemicals are called neurotransmitters, and the process is called NEUROTRANSMISSION.
The order of neurotransmitter/receptor interaction that results in an electrical signal impulse and the release of another neurotransmitter for interaction in the synaptic cleft (signal conduction through a neuron) is from Dendrites--> Cell body--> Axon-->Axon terminals>
DENDRITES extends from the cell body of a neurone to receive messages at neuromuscular junction from other neurons. The CELL BODY directs all activities to the axon. The AXON is a long single fibre that transmits messages from the cell body and ends in terminals forming a synapse. Nerve impulses arrives at the axon terminal causing the release of neurotransmitters. The neurotransmitters binds to receptors at the dendrites of another neurons. The electrical signal impulses generated causes the release of neurotransmitters in another neuron.
