Explanation:
Much energy is demanded within a short period in a sprint as opposed to long-distance that mainly demands stamina. During sprints, therefore, the energy demands by the muscles my outpace the supply by energy because oxygen is not reaching fast enough for aerobic cellular respiration. This is why sprinting cannot be sustained for long without accumulation of lactic acid in muscles – due to glycolysis metabolisms being the main source of energy.
IN long substance however, the runner does not sprint the entire marathon but run at sustainable speeds allowing the energy demands by the muscles to be met by the more effective aerobic respiration
It's B
Explanation:
Because the fossil record shows how organisms have evoluate from relatively simple organisms to more complex organisms
Answer:
Point A - Intrusive igneous rock
Point B - Extrusive igneous rock
Explanation:
Intrusive igneous rocks are rocks which is formed by molten magma that cools and solidifies below and within the surface of the earth, thereby forming large crystals beneath the earth surface. Examples of Instrusive igneous rocks gabbro, granite, peridotite etc.
Intrusive Ignoeus rock is formed at point A in the diagram given above.
Extrusive Ignoeus rock, on the other hand, is the opposite of Intrusive igneous rock. Extrusive igneous rock is formed when molten rocks, called magma, erupts from beneath the earth and cools and solidifies on the surface of the earth, thereby forming small crystallized rocks. Examples of extrusive igneous rocks are basalt, pumice, etc.
Extrusive Ignoeus rocks would formed at point B in the diagram above.
<h2>Anatomy of Aorta</h2>
Explanation:
- The protein elastin is found in connective tissues all through the body. It is eminently found in the extracellular lattice of the skin just as the inward organs of the body. The name elastin sounds a lot of like 'flexible.' This is no fortuitous event. The elastin protein is adaptable and gives numerous tissues their versatility.
- Inferable from its exceptional capacity to extend and withdraw, the aorta additionally fills in as a store that changes the profoundly compelled and pulsatile heart yield into a progression of moderate variances.
- The tunica intima comprises of a solitary layer of ECs that lines the lumen of the vein and is moored to the fundamental cellar film, an exceptionally particular ECM organize comprising basically of laminin, collagen type IV, fibronectin, perlecan, and heparan sulfate proteoglycans.
- This storm cellar layer additionally assumes a vital job in flagging occasions that direct EC movement, intrusion, expansion, and survival. The cellar film together with the inward flexible lamina (IEL) fills in as an interface between the tunica intima and tunica media.
