Echinoderms are organisms that live on the ocean floor. Echinoderms include sea stars and brittle stars, sea urchins, and sea cu

cumbers. Sea cucumbers move by swimming or squirting water. Sea stars and brittle stars walk on the sea floor using tube feet. Describe the environment in which these organisms live. Predict the adaptations that would be beneficial to echinoderms for living in this environment.

Imagine these two elements, element A and element B are solids. The two elements are poured into a beaker and mixed. Illustrate
Kryger [21]

Chromatography is a simple technique in principle, it remains the most important method for the separation of mixtures into its components. It is quite versatile for it can be used to separate mixtures of solids.

Explanation:

  • The two elements of chromatography are the stationary phase and the mobile phase. There are many choices of stationary phases, some being alumina, silica, and even paper.  The mobile phase, in liquid chromatography, can also vary.  It is often either a solvent or a mixture of solvents and is often referred to as the eluant.
  • A careful choice of eluting solvent helps to make the separation more successful.  The mixture is placed on the stationary phase.  The eluant passes over the mixture and continues to pass through the stationary phase carrying along the components of the mixture.
  • Chromatography is used in industrial processes to purify chemicals, test for trace amounts of substances, separate chiral compounds and test products for quality control. Chromatography is the physical process by which complex mixtures are separated or analyzed.
  • Chromatography is based on the principle where molecules in mixture applied onto the surface or into the solid, and fluid stationary phase (stable phase) is separating from each other while moving with the aid of a mobile phase

Why is the microscope important to the study of microlife?
Sophie [7]
Wait this is highschool biology?! 
Woah... thought it would be harder....


Anyways, see "micro" means really small, so small that your bare eyesight can't take it (or see it, I don't care). A microscope was meant to see things that our eyes can't. Since humans cant see microlife we use a microscope. 

Mind Blown...

It seems plausible that planets and moons with liquid water could support microbial life, even though CO2 is the only available
Rudiy27

Answer:

The metabolic capacities should be:

Bacteria that fulfill replicative cycles, have a metabolization that requires a substrate or a metabolite, coexist in extreme environments where their method of survival is sporulation.

Ability to admit genetic mutations between different bacterial colonies for their possible evolution, an ideal environment with pH, gases, and substrates according to the life of the bacterial colony, which is often called as a culture medium.

Explanation:

Temperature is essential in bacterial growth, as is the pressure and environment that surrounds the bacteria.

Something that must be taken into account is that other microorganisms coexist with the bacteria in the medium, since they can be limited to their colonization, an example of this is the gram negative and positive bacteria, coccoid and bacilloid, which generally are not compatible with the penicillium fungus, as this, as a product of its metabolization, releases a substance called penicillin that prevents the colonizing growth of other species of microorganisms such as this type of bacteria.
