Answer:
Hypertonic blood draws water out of the interstitial fluid, which makes the interstitial fluid hypertonic. This, in turn, draws water out of the cells.
Basically an hype tonic blood has high solute potential,( low water potential) compare with the surrounding plasma and the interstitial fluid. Thus the interstitial fluid is hypotonic to the blood.
Consequently,water with higher potential moves from the interstitial fluid medium into the blood by osmosis through the capillary endothelial. This raises the water potential of the blood, lowering the solute potential, thus making it hypotonic to the interstitial fluid; which is now hypertonic(lower water potential ,due to loss to the blood by osmosis).
Since the interstitial fluids is now hyper tonic to the surrounding cells, water moves from the hypo tonic surrounding cells through osmosis into the interstitial fluids. The sequence continues until a stable internal environment is achieved,
Answer:
4, 3 5, 1, 2.
Explanation:
The events of muscle contraction begins from the presynaptic neuron, which cause the influx of Ca+, and the release of acetycholine neurotransmitter into the synaptic cleft.
The Ach, binds with the receptors in the sarcolemma, leading to opening of Ligand gated Na+ channels. Therefore Na+diffuses in, causing depolarization, and propagation of action potential along the sarcolemma spreading to the T-tubules.
This is followed by opening of Calcium channels leading exist of Ca+ from the sarcoplasmic reticulum.
The Calcium binds with the troponin, and Tropomysoin exposed the myosin binding sites on the actin filament.Thus cross-bridge is formed by the myosin head with thin filaments which shortened the sarcomere, leading to contraction of muscle fibres.

Answer:
TRUE
Explanation:
The green plants have green pigments present on their leaves, which are commonly known as chlorophyll. This chlorophyll pigments have the ability to absorb the necessary amount of sunlight, that is required to carry out the process of photosynthesis. Photosynthesis usually refers to the process where the green plants can synthesize their own food in the presence of sunlight, water (H₂O), and carbon dioxide (CO₂), and in return, it liberates food (glucose) and oxygen (O₂) that is essential for the survival of all living organisms.
The reaction that takes place during the time of photosynthesis is given below-
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
This process converts light energy into chemical energy, that is stored in the molecules of glucose.
Hence, the above statement is TRUE.
