Answer:

Gel electrophoresis

Explanation:

Gel electrophoresis is used in the separation of large sized particles such as macromolecules through the use of the differences in size and charges.

This technique makes use of a gel which is subjected to electric current and the particles move to sides with the same type of charge or size.

It is also used to separate sections of DNA by size in order to isolate specific genes.

Water, H2O, and methane, CH4, are both covalent substances. Why is water a liquid at room temperature while methane is a gas? A
tino4ka555 [31]

The right answer is D.

Intermolecular forces lead to the assembly of microscopic systems. They are responsible for the cohesion of matter in most macroscopic phases. These are weak forces compared to covalent bond strengths. They do not modify the nature of the molecular species and only influence their mode of assembly. The most well-known intermolecular bonds are the Van der Waals bond and the hydrogen bond.

The greater the intermolecular forces, the more the aspect of the element will tend to be more condensed (gas <liquid <solid).

In addition to transporting oxygen from the lungs to the tissues, hemoglobin is also involved in transporting carbon dioxide fro
neonofarm [45]

The correct option is (C) Carbon dioxide reacts with an amino group to stabilize the deoxyhemoglobin state.

In addition to transporting oxygen from the lungs to the tissues, hemoglobin is also involved in transporting carbon dioxide from the tissues to the lungs where, Carbon dioxide reacts with an amino group to stabilize the deoxyhemoglobin state.

<h3>How does hemoglobin contribute to the movement of carbon dioxide from the tissues to the lungs?</h3>
  • The transport of carbon dioxide in the blood is influenced by a number of factors. First, blood contains more carbon dioxide soluble molecules than oxygen. The plasma contains 5–7% of the total dissolved carbon dioxide.
  • Second, carbon dioxide can enter red blood cells and bind to hemoglobin or it can bind to plasma proteins. In this form, 10% of the carbon dioxide gets transported.
  • A substance known as carbaminohemoglobin is created when carbon dioxide binds to hemoglobin. Hemoglobin and carbon dioxide can bind to one other again.
  • As a result, when it gets to the lungs, the carbon dioxide can separate from the hemoglobin without restriction and leave the body.
  • Third, the bicarbonate buffer system is responsible for transporting 85% of the carbon dioxide molecules.

What two types of geologic processes formed the major features of the California landscape
MrRissso [65]

Answer:

Geological processes are those process that occurs on the surface and subsurface regions of the earth crust. They facilitate in shaping the Earth, and helps in concentration of resources over a region. These processes occurred millions of years ago, the chances are their that they will occur in future as well. Some of the major features of the California landscape develop as a result of plate tectonics and other features develop due to the process of erosion under the influence of wind, water, ice and other features.
