How Does Fish Breath
Fish seems to have nostrils like the ones human beings have. but they are not used for breathing at all.They are only used for smelling things and is not part of the fish respiration system. Instead, fish breath through the

Photosynthesis not just happens on plants, but also on algea and lots of bacteria. Here we only talk about the photosynthesis on plants. Plants use photosynthesis to make the useless carbondioxide into useful organic compounds (such as sugar) for their
In biology, we keep hearing abot cell wall and cell membrane, so what are the differences? Well, the first difference is, not every cell has cell wall, but every cell does have cell membrane. Cell membranes are on both plant
Gene mutation is a change in DNA sequence that can make a gene different from the original one permanently. Gene mutation can happen in two ways. The first way is that the mutation occurs during lifetime (after being born). This
DNA and RNA are totally different. DNA, stands for Deoxyribo Nucleic Acid, is a long polymer with a deoxyribose and phosphate backbone and four different bases: adenine, guanine, cytosine and thymine (A,G,C,T), while RNA,stands for Ribo Nucleic Acid, is a polymer with a
Metabolism is a term related to energy most of the time. Indeed, metabolism is made up of a series chemical reactions that ultimately produce energy from food. Metabolism has two processes. The first one is catabolism, which means foods are
Aerobic and anaerobic are antonyms to each other. Aerobic means “with oxygen”, so aerobic exercise is a metabolic process that requires oxygen to run through. Anaerobic means “without oxygen”. When muscle does not have enough oxygen during operation, the exercise
Wavelength, period and frequency are closely related to each other. By definition, wavelength is just the distance between two identical points in the adjacent cycles of a wave, and period is the time it takes to complete one cycle
Current, voltage and resistance are basically the three things we need when analyzing a circuit. An electrical circuit is basically a path that can conduct electricity, in other words, it is a path that allows free electrons to flow, just
In electrical science, Ohm’s Law is so useful that it helps engineers to calculate either current, voltage, or resistance, if any two of these factors are given. Actually Ohm’s Law is the relationship between current, coltage and resistance. Ohm’s
