Sodium and chloride would be dangerous to the body in the natural state .explain why sodium chloride is a comparatively inert molecule
ever seen sodium dropped into water? I wouldn't want to be anywhere near that! ❌💥 sodium (Na) belongs to a special group of metals called the alkali metals which are all a 🤬pretty reactive bunch🤬 due to their atomic makeup (a single outer valence electron) . These metals react violently with water to produce a metal hydroxide and hydrogen gas. You know what else has a lot of water in..? YOU! 💧 Us humans are about 70%ish water, so let's not get sodium METAL anywhere near us! Sodium chloride (NaCl) , on the other hand, is a stable IONIC compound, a special type of substances that are super stable and dissolve well in water without any crazy reactions! This is because sodium reacts really well with chlorine (Cl) and once they form a molecule together - they don't feel like reacting much more! Chlorine is a perfect match for sodium as it wants an extra electron that sodium has up for grabs. The result? A match made in heaven 💕 Sodium chloride salt. stable, safe (in moderate amounts 🍟) and naturally occuring in the ocean 🌎

Osteoclasts are packed with lysosomes. Describe how both parts the principle of complementarity applies to this structure/function relationship. Describe lysosomes and osteoclasts and their mechanisms of action. Is osteoclastic scribing pathological?
Osteoclast is a type of bone cell that is essential for repair, remodelling and maintenance of the bones. This means these cells need to digest the broken parts of the bones in order to fix them. Lysosome is an organelle in the cells that is very acidic and conta8ns digestive enzymes and its function is to digest the dead cells or parts of the cells which is essential in any cell, especially when the function of that cell is to repair or maintain. Such as in Osteoclasts that need to digest the broken parts of the bone cells in order to repair them. An imbalance in the function of these cells (osteoclastic activity) could cuase diseases.

48% complete math homework regularly.55% have B average or better. 40% do not complete math homework and have less than B average. using this data does it appear that students completing homework regularly moreLikely to have B or better in math
Hi Alexey, The question seems a little confusing. I've done my best to try and summarise. Can you confirm if this is correct: 1. 48% complete math homework regularly. 2. 55% of the 38% have B average or better. 3. 40% do not complete math homework 4. 40% of the above have less than B average. The fourth step is the one that wasn't clear. If it's possible, just enter the question exactly how you see it and I'll have a closer look. Just re-submit the question :)

What are the 3 subatomic particles and what are their charges?
Electrons surrounds the nucleus in the electron shell and has a charge of -1. Proteins are located within the nucleus and have a charge of +1. Neutrons are also located in the nucleus and have a charge of 0.

Osteoclasts are packed with lysosomes. How are both parts the principle of complementarity applies to this structure/function relationship. This requires that you describe lysosomes and osteoclasts and their mechanisms of action. Is osteoclastic bad?
Osteoclasts are responsible for breaking down bone tissue so that the skeleton can be maintained and repaired. Lysosomes are vesicles containing hydrolytic enzymes (they break things down), which are released by the osteoclast to break down certain parts of the tissue (the exact mechanism of action is rather complex). So, osteoclasts wouldn't be able to function without lysosomes, as they provide a mechanism for the controlled release of enzymes. Osteoclasts aren't bad- they're essential for the maintenance of the skeleton- sometimes it is useful to break things down!
