Yuliya22 [10]

Answer:

Hydrogen bonding

Explanation:

A hydrogen bond is a form of the electrostatic force of attraction which takes place between the hydrogen atom and a more electronegative atom such as nitrogen, fluorine, and oxygen.
Hydrogen bond falls in the category of weak forces.
In size-exclusion chromatography, the type of interaction that takes place between the proteins and dextran is hydrogen bonding.
The hydrogen bonding is possible because dextran, being a polysaccharide of glucose has several hydroxyl groups and thus, they get involved in the hydrogen bonding.

What happens to the atmosphere and hydrosphere during a hurricane?

STatiana [176]

The hot ocean waters warm the air above them and evaporate very large amounts of water vapor. This water vapor is the fuel for a hurricane as it strengthens through the hidden heat released by condensation of the vast amounts of water vapor.

Quién propuso el primer mecanismo de herencia a partir de la observación y la experimentación con plantas?

marusya05 [52]

Answer:

Gregor Mendel

Explanation:

Gregor Mendel fue un naturalista, biogista y matemático que demostró por primera vez los principios de la herencia utilizando su trabajo sobre las plantas de guisantes.

Publicó su trabajo en "Experiments in Plant Hybridization" en el año 1866. Al controlar la polinización, Mendel pudo cruzar plantas de guisantes con diferentes formas de rasgos. En el primer conjunto de experimentos de Mendel, experimentó con solo una característica a la vez. Los resultados de este conjunto de experimentos llevaron a la primera ley de herencia de Mendel llamada ley de segregación (Bio Libretexts).
