<span>Biological scientists are research scientists who examine how living organisms relate to the environment. They can specialize in any number of plant, animal or environmental studies. Biological scientists most often have earned a master's or doctoral degree in their specialization; such degrees offer the opportunity to develop research while finishing their education. Some low-level positions related to biological science are available to those holding baccalaureate degrees.</span>

What is the likeliest limiting factor restricting phytoplankton to approximately the top ten feet of the ocean, rather than deep
serg [7]

Quality of light is the limiting factor restricting phytoplankton to approximately the top ten feet of the ocean, rather than deeper

Explanation:

When sun rays pass through the water in the oceans, they are quickly diffused and cannot penetrate very deep into the deep water layers. Remember that phytoplanktons are photosynthetic organisms and hence require sunlight to manufacture their own food. They, therefore, cannot grwo in deeper layers of the oceans. They are only found in the photic zone.

The quality of light is especially of most importance and hence the major limiting factor. Red light, of longer wavelength, and which is the major wavelength of light that is used the most by photosynthetic organisms, diffuses very fast than blue light when it passes through water. Therefore the more reason phytoplankton is found in the top ten feet of the ocean, rather than deeper.

proteins need to be denatured using an anionic detergent such as sds before gel electrophoresis because: select all that apply.
grandymaker [24]

The majority of proteins contain a uniform positive charge, and a uniform neutral charge, and most proteins have intricate three-dimensional structures that might affect how well they travel through the gel electrophoresis. For these reasons, proteins need to be denatured. Here, the right answers are A, B, and D.

Protein separation is accomplished using a molecular technique called sodium dodecyl sulfate-polyacrylamide gel electrophoresis, which operates in the proximity of an electric charge. Proteins are separated using SDS-PAGE according to their electrophoretic mobility. Protein charge, shape, and structure all affect electrophoretic mobility.

To proceed in the direction of the positive terminal, the protein molecules need to have a constant negative charge (anode). The overall charge of a protein is determined by the amino acid content of the protein as well as the charge of the individual amino acids.

Thus, depending on the total makeup of amino acids, the charge may change. Depending on the ratio of different amino acids, the total charge of the proteins can be positive, negative, or neutral. The SDS treatment gives the proteins a consistent, negative charge. Then, according to size, the negatively charged amino acids flow toward the positive terminal.

Complete question:

Proteins need to be denatured using an anionic detergent such as SDS before gel electrophoresis because: Select all that apply.

A - most proteins have a uniform positive charge

B - most proteins have complex three-dimensional structures that can impact their movement through the gel

C - the overall charge of a protein depends on the amino acid composition of the protein and can vary greatly

D - most proteins have a uniform neutral charge

Question

The pain you feel from accidentally burning your hand while cooking is an example of

neurons taking information from your senses (touch, in this case) to your brain.

Which of the three types of neurons is this an example of?

Answer:

Motor is the correct Answer-

The central nervous system uses the information to send messages through motor neurons to tell the body how to respond to the information.
