Seafloor spreading is a geological process where through volcanic activity, a new oceanic crust is formed, and the crust is made of rocks that move away from the ridge as new crust develops. The formation of the new crust comes from the increasing molten material from the mantle by convection current.
Once the molten magma comes to the ocean crust, it cools and pushes away the ...

In systems where more external logic currents transmit through multiple U/I interconnects with a single microprocessor, U/I polling is used. The microcomputer frequently calls each external logic circuit and examines whether it has the necessary service. If the external logic circuit does not require servicing, the microcomputer investigates the next external logic circuit.
The U/I ...

The bolus is a mixture of food formed like a ball in the mouth while the chyme is a liquified semi-solid mixture of food formed in the stomach, which is the key difference between bolus and chyme. For digestion, ingested food is formed into these mixtures. The bolus is created in the mouth with the mixing of various fluids, and the chyme is produced in the stomach that is mixed with ...

Melting is a phase change, and there are three primary phases in which matter can exist, including solids, liquids, and gas. When a solid substance becomes liquid, this occurrence is called melting or fusion, and for a substance to melt, energy must be provided. This energy can be delivered as heat or pressure.
The temperature at which a solid becomes liquid is called its melting ...

Centrioles enable the synthesis and organization of spindle fibers, while centrosomes provide attachment to the spindle fibers. The centriole is a small cylindrical organelle present in most eukaryotic cells. Centrioles contain tubulin protein as their primary protein.
The centriole's cylindrical composition is made up of several groups of microtubules that are placed in a 9+3 ...

Yeast and baking powder is mostly used for baking purposes. Baking powder is a chemical ingredient known as a mixture of sodium bicarbonate and acid salts. On the other hand, yeasts are eukaryotic microorganisms grouped with members of the fungus kingdom. This grouping is the significant difference between yeast and baking powder.
Baking powder is also made by blending baking soda ...

Cilia are fine hair-like projections from eukaryotic cells. The respiratory tract has a plethora of cilia that work in harmony to eliminate fluids and other foreign particles. Single-celled organisms have these projections, which assist them with locomotion. The rhythmical movement of cilia allows them to travel freely.
Cilia in human bodies protect individuals from germs in the lungs ...
