Answer:
SA Node
Inter-nodal Pathways
AV Node
AV Bundle
Bundle Branches
Purkinje Fibers
The SA nodes functions first for setting pace for the heart, then the inter-nodal pathway make link b/w SA and AV node. AV node is site of delay when contraction of atria occurs. AV bundle is the mean of electrical link b/w atria and ventricle. The conveying of impulse to the inter-ventricular septum occurs through bundle branches, while conveying of impulse throughout and along the walls of ventricle occurs through Purkinje fibers.
<span>In organisms that breed sexually, the body cells have a diploid number, or 2n, and the gametes have a haploid number, n. The diploid number of chromosomes is double that of the haploid number. So the the diploid number would be 24 and it is produced when the pollen, containing the sperm, fertilizes the egg.</span>
Answer:
The colours like green and yellow are being reflected.
As we know if the colour is green then it is reflecting green light
Explanation:
The heart, blood and blood vessels work together to service the cells of the body. Using the network of arteries, veins and capillaries, blood carries carbon dioxide to the lungs (for exhalation) and picks up oxygen. From the small intestine, the blood gathers food nutrients and delivers them to every cellular.
Bacteria obtain energy and nutrient by performing photosynthesis. First plants absorbs light, electrons transport less to the reduction of NADPH+ to NADPH, then energy is created, finally CO2 is converted into carbohydrates (process also called carbon fixation”.
