The purpose of a vortex instrument is to mix "small vials of liquids" in a laboratory.

Explanation:

A vortex instrument or a mixer is an laboratory instrument which is used to mix liquids in small vials.

The term vortex means swirling of a mass of air and this instrument also mixes liquid through swirling movement inside a tube.

A vortex unit is run by an electric motor which moves a rubber cup attached to the drive shaft.

The rubber cup swirls or oscillates in a circular motion and when a test tube with the liquid is pressed in the cup, the liquid contents get mixed through the transmission of the circular motion from the cup to the liquid. The speed of the rotation can be controlled.

Answer:

The answer is the flexibility of DNA.

Explanation:

The flexibility os DNA is what allows transcription factors at distant binding sites to do their job. The DNA loops like cooked spaghetti to bring far-off binding sites and transcription factors close to general transcription factor or mediator proteins.

When recombinant DNA is inserted into the genome of a host organism, what's created? A. A genetic marker B. A restriction enzyme
PIT_PIT [208]

The answer is C.

Transgenic means that one or more DNA sequences from another species has been introduced by artificial means. For example, animals usually are made transgenic by having a small sequence of DNA injected into a fertilized egg or developing  embryo. Transgenic plants can be made by introducing foreign DNA into a variety of different tissues.

Most transgenic organisms are generated in the laboratory for research purposes. Others have been developed for commercial purposes  such as golden rice that has been modified to produce beta-carotene, the precursor to vitamin A.

In the combined processes of glycolysis and cellular respiration, what is consumed and what is produced?.
IrinaVladis [17]

Glucose is consumed and carbon dioxide is produced during the combined processes of glycolysis and cellular respiration.

Glucose is a simple sugar. Glucose is the most common monosaccharide, a type of carbohydrate. Glucose is primarily produced by plants and most algae during photosynthesis from water and carbon dioxide with the help of sunlight, where it is used to produce cellulose in cell walls, the world's most abundant carbohydrate.

A glucose molecule is gradually broken down into carbon dioxide and water during cellular respiration. Some ATP is produced directly along the way in the reactions that transform glucose. However, much more ATP is produced later in the process known as oxidative phosphorylation. The movement of electrons through the electron transport chain, a series of proteins embedded in the inner membrane of the mitochondrion, drives oxidative phosphorylation.

During glycolysis, a six-carbon sugar, glucose, undergoes a series of chemical transformations. It eventually degrades into two molecules of pyruvate, a three-carbon organic molecule. ATP is produced in these reactions.

How do proteins and fats provide energy for the human body?
pickupchik [31]
Fats are used for energy after they are broken into fatty acids. Protein can also be used for energy, but the first job is to help with making hormones, muscle, and other proteins. Broken down into glucose, used to supply energy to cells. Extra is stored in the liver.
