Answer:
Ionic bonding is the complete transfer of valence electron
Explanation:
In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.
Answer:
Whent he people went to the moon they told them what it was
Explanation:
all 3 are related to each other through their involvement in protein synthesis and transport.
Ribosomes are the sites of protein synthesis and carry out this work by assembling the amino acids in the appropriate sequence, as dictated by the mRNA (messenger RNA).
These cell organelles are most commonly found embedded in the endoplasmic reticulum. Large scale protein synthesis is possible due to the very large surface area offered by the endoplasmic reticulum to the ribosomes.
The main function of the endoplasmic reticulum is to transport the newly synthesized proteins over to the Golgi apparatus. The primary role of the Golgi apparatus is to modify the proteins and encase them into vesicles. From here they are transported to the various parts of the cell.
this is why it's the answer!
The three evidences that show that the particles of substances are in continuous motion are given below:
1. DIFFUSION: Diffusion is the movement of particles of a substance through a medium, from a region of higher concentration to a region of lower concentration. Particles of substances (solid, liquid or gas) tend to move from an area where more of them are present to an area where only few are present until they are evenly distributed. For example, a can of gasoline left in an open air can easily catch fire because the particles of gasoline can be easily carried by air to the nearest source of ignition.
2. OSMOSIS: Osmosis is the process by which solvent molecules move from a less concentrated solution to a more concentrated solution through a semi permeable membrane; the movement typically continues until the concentrations of solutes on both sides of the membrane are equal. Osmosis is a very crucial process in the biological systems of living organisms, where the plasma membrane, which is semi permeable in nature only allow specific small particles to pass through. Water molecules pass through the plasma membrane by diffusion via the phospholipid bilayers; osmosis thus provide the major mean via which water is moved in and out of living cells
3. BROWNIAN MOVEMENT: When a pollen grain, which is suspended in a drop of water is observed under a microscope, it will be seen that the pollen is moving about in a zig-zag manner. The zig zag movement of the pollen is due to the continuous movement of the particles of water on which the pollen was suspended. This phenomenon was first observed by a botanist, a British scientist called Robert Brown in 1827 and that was why the phenomenon was named after him.
HNO3 and H2SO4 are Arrhenius acids which will increase the concentration of H+ when dissolved in water.
KOH and Ca(OH)2 are Arrhenius bases that increase the concentration of OH- when dissociated in water.
