What Is Agar?

Agar is a type of sugar in a gelatinous form made from algae and typically used to grow bacteria in a lab. Bacteria eat the agar and help scientists perform culture tests. Agar is one of those materials that can be found in science laboratories. It is, in fact, one of the most distinctive of

Mesocrystal Formation Of Calcite Crystals In Solution

Crystals ─ which are a ubiquitous form of matter in the environment, within living organisms, and throughout technology ─ are created along many pathways. Some crystals grow from a solution by a so-called “classical” mechanism in which individual atoms, ions or molecules (the crystals’ building blocks) are added to the crystal surface one at a

Scientists Question Old Paradigms On Tannin Interactions With Organic Nitrogen Compounds And Enzymes

Among plant secondary metabolites, tannins represent one of the main groups. Historically, they were used to treat animal skin in order to produce leather, because tannins stabilize proteins in animal skin, thereby making it more durable. The precipitation of proteins by tannins is a key characteristic of tannins. Over time, more surprising abilities of these

What Sugar Is Found In RNA And DNA?

The sugar found in RNA is ribose, whereas the sugar found in DNA is deoxyribose, both of which are 5-carbon sugars. Both types of sugars are important components of nucleotides. The sugars which can be found in nucleic acid are pentose sugars, part of what makes up DNA. Deoxyribonucleic acid, or DNA, is often referred

Difference Between Mitosis And Meiosis

The difference between mitosis and meiosis is in the process by which each form daughter cells from a parent cell. Mitosis has one round of cellular division and genetic separation whereas meiosis has two rounds. The two processes are also different because in mitosis the daughter cells are exactly identical to the parent cells compared

The Bioelectrochemically Assisted Electrodialysis

The microbial electrolysis cells are innovative technologies that utilize “electroactive microorganisms” as biocatalysts into an electrochemical device; these electroactive microorganisms can exchange electrons with a conductive material through the external electron transfer mechanism, using the conductive material as electron donor or acceptor. The current generation from a microorganism’s metabolism was firstly reported in 1911 by

Costs And Benefits Of Bioenergy Alternatives For Birds

A predicament the United States faces is the simultaneous threat of climate change and the rising energy demands of its growing population. This, in combination with the economics and politics surrounding crude oil production, has created a national interest in diversifying and growing the domestic energy portfolio. In 2007, the U.S. Congress enacted Renewable Fuel

Hydropower Pros And Cons

Hydropower has several pros and cons that make it an interesting choice depending on each situation. Some hydropower pros are nearly continuous energy supply, low maintenance cost, and a renewable energy source. Some hydropower cons are high upfront cost, impact to ecosystems, and need to store the energy created. As the weather gets colder and

Nuclear Energy Pros And Cons

Nuclear energy pros and cons can be separated into the non-greenhouse gas emitter, consistent supply of energy, and low operating cost for nuclear energy pros compared to potentially highly environmentally damaging, high startup cost, and radioactive waste disposal for nuclear energy cons. Few energy sources are as controversial as nuclear power. In fact, many people

Wind Energy Pros And Cons

Wind energy pros and cons can be separated into renewable, low operating cost, and energy independence for wind energy pros compared to intermittent energy, large geographic footprint, and limited geographic implementation for wind energy cons. Combating global warming has been on the many people’s mind for decades. Although this remains a controversial topic for some,
