Replacing native gel electrophoresis with SDS results in eluates with no enzymatic activity because it confers a negative charge to proteins, thereby neutralizing them.
<h3>What is sodium dodecyl sulfate?</h3>
The sodium dodecyl sulfate (SDS) is a detergent used in molecular biology laboratories.
This detergent (SDS) confers a negative charge to proteins, thereby neutralizing them (loss of their enzymatic activity).
In conclusion, SDS results in eluates with no enzymatic activity because this detergent may neutralize them.

The scientists will use Relative dating. It is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages. Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.
Answer:
The correct answer is - the placenta, the site of exchange of materials between the mother and the fetus.
Explanation:
In the given diagram there is a representation of a human embryo developing in the uterus. Different parts are numbered and the number three represents the site of exchange of materials between the mother and the fetus and this organ is called the placenta. It is the organ that develops between fetus and uterus during pregnancy that allows substances such as nutrients, to diffuse from the mother's blood to the fetus and connected by the umbilical cord.
Answer:B. speeds up the growth of the plant on the shaded side
Explanation: plants have hormones.these hormones controls the activities of the plants by serving as specific chemical signals between cells. They are usually moved from where they are produced to the region of the plant where they act. Eg auxin, cytokinin, gibberellin etc
Auxin has the ability to cause enlongation in shoot cells and root . They cause the cells of plant to stretch. they are produced in the apical meristem,buds and leaves. They also causes the suppression of side buds.
When a plant is placed in a dark shade and a side is exposed to light, auxin gathers on the shaded part of the plant. This causes the cells in that area to enlongate and the plant bends towards the light.
A coronary ligament consists of two layers- an upper and a lower. The upper layer is formed by the reflection of the peritoneum from the upper margin of the bare area of the liver to the under surface of the diaphragm, and is continuous with the right layer of the falciform ligament.
