The organs that are involved in the excretion of water from the body include:
1. Kidneys (Primary organ for water removal)
2. Skin
3. Lungs
The kidneys play a key role in maintaining the water balance of the body. The kidneys control the water levels in the body by conserve water when there is shortage, and they can expel excess water by diluting the urine.
The skin has water in it. This water gets lost to the atmosphere by the process of evaporation. This is independent of the process of sweating wherein the skin actively releases water in the form of sweat to cool the body.
Our breath has a lot of moisture in it. This moisture is present due to the evaporation process taking place within the lungs due to the heat of the body. Thus lungs also become a part of the water loss mechanism.
1. D) Saturated triglyceride since they have the most C-H bonds.
2. B) Nucleic acids contain hydrogen, oxygen, nitrogen, carbon, and phosphorus.
All of them will lead to depolarisation.
<h3><u>Explanation</u>:</h3>
Depolarisation is a phenomenon ebochor occurs in the excitable tissues of our bodies, namely the neurons and the muscle T junctions. Here the membrane is already polarised by means of difference in charges as well as concentration of ions on both sides of the cell membrane. With a single stimuli, this change in concentration is gone, and this is de polarisation.
This phenomenon occurs because of the opening of the ion channels like potassium channels and sodium channels which leads to a diffusion of ions from both sides to the other achieving a more or less equal concentration on both sides of cell membrane.
Now this opening of the ion channels can be triggered by means of different stimuli. In case of neurons, the opening of the post synaptic ion channels are guided by the chemical impulse taking in synapse.
In case of inter neuron transfer, the ion channels open due to change in voltage of the previous part of the axon.
In case of organ of Corti, the sodium channels open due to mechanical events occurring inside cochlea. So ion channels can open in any form will lead to change in potential.
The 2 major components or parts that compose or make up the plasma membrane of a eukaryotic cell would be the phospholipids arranged as a bilayer, having phospholipids arranged side by side in an upright and inverted manner, allowing for the hydrophobic and hydrophilic regions to interact respectively, and also Protein molecules, more specifically Transmembrane Proteins and Integral Proteins.
