Answer:
Plasmin
Explanation:
Plasmin is a serine protease also referred to as fibrin digesting enzyme, it is responsible for the dissolving or degradation of blood clot. The process by which plasmin degrades blood clot is called fibrinolysis. Note that plasmin (active) is formed from an inactive enzyme called plasminogen.
Answer: summation
Explanation:
The process which determine if an action potential will be generated or not depends on the combined effects of the signal inputs from multiple sources of synapse or from the repeated signals from the same synapse.
If the input signals reach the threshold voltage, action potential will be generated. (all –or –none principle).Therefore, this process is a determinant of the likelihood of action potential generation and it is called summation.
Summation is the ability to integrate multiple PSPs at multiple synapses.it is the process that determine if an action potential will be generated by combined effects of inhibitory or excitatory signals.
Based on the pathways and voulme of applied stimuli in the presynaptic neuron;
The signals can be temporal summation ( consecutive signals produced from the same synapse)where action potential of high frequency in the PSN generated action potential in the post synaptic neuron, which summate with one another. Or Spatial where signals inputs are from multiple presynaptic cells.
Answer:
B. Meiosis I
Explanation:
In meiosis I, it starts with a diploid cell with a homologous chromosome pair. The crossing of genetic material between chromosome pairs also occurs in this stage. The alleles containing the same trait would get separated so a new combination of alleles can be produced.
Answer:
Petiole
Explanation:
The petiole is the part of the leaf that attaches the leaf to the main stem of the plant. Depending on the leaf structure of the plant, some leaves may be devoid of a petiole, and be regarded as apetiolate.
