Answer:
a) only living things are made of cells
<span>For example, a prokaryotic cell is an uncivilized society while the eukaryotic cell is a more systematized society, with coordination and cooperation and a leader.
Eukaryotic cells has a nucleus while prokaryotic cells do not. Eukaryotic cells have more than one chromosomes and is usually multicellular while the prokaryotic cells has only one chromosome and it's not even a genuine one, only plasmids and has unicellular however some cyanobacteria maybe multicellular. Eukaryotic cells have genuine membrane-bound nucleus, lysosomes and peroxisomes while prokaryotic cells display just the opposite of eukaryotic cells. Eukaryotic cells recombines its genes by meiosis and by the fusion of gametes while the prokaryotes does by partial and undirectional transfer of DNA.</span>
Answer:
1) Pacemaker impulse generation.
2)AV node impulse conduction
3) AV bundle impulse conduction.
4) Bundle branches conduction.
5) Purkinjie fibres impulse conduction.
Explanation:
The cardiac conduction has following components.
1)SA node is the heart pacemaker in the right upper quadrant of heart. It generates electrical impulses and these impulses then move through atria and AV node to the Purkinjie fibres.
2) The impulses reach AV node. It controls heart rate. It serves as electrical relay station which slows the electrical current sent by SA node before the signals has passed to ventricles.
3) AV bundle is continuation is AV node and it transmits impulse from AV node to the Purkinjie fibres.
4) Electricle impulses from bundle of his passes through bundle branches (right and left ) to Purkinjie fibres.
5)Purkinjie fibres take the impulses from the bundle branches to the myocardium of ventricles.
Malarial parasites are caused by Plasmodium parasites, these parasites infect humans via the bite of infected Anopheles mosquitoes. Some of these mosquitos are Plasmodium vivax, P. falciparum, <span>P. ovale, and P. malariae</span>
