Fill in the blanks correctly: _____________ carbohydrates are more beneficial to the body than ___________ carbohydrates because
Zolol [24]

The complete statement will read, Complex carbohydrates are more beneficial to the body than simple carbohydrates because these types of carbs contain more overall nutrients.

<h3>Complex carbohydrates, and simple carbohydrates</h3>

Generally, Complex carbohydrates, are a type of carbohydrates that are produced from sugar molecules that are held together in long complex chains.

While simple carbohydrates are a type of carbohydrates that are split down fast by the body of the consumer to be utilized as energy.

tructures used in recombinant DNA technology to carry the DNA from the cells of one species to the cells of another species are
Kobotan [32]

The process of fusing two or more DNA molecules to produce a hybrid is known as recombinant DNA. Restrictions endonucleases and ligases are two classes of enzymes that enable the technique.

When a restriction endonuclease detects a particular DNA sequence, it makes cuts inside or near that sequence. The recognition sequence of a restriction enzyme will haphazardly appear on every (1–4)n bases along a random DNA chain. The equation states how many fragments ends (measured in moles) are produced when a restriction enzyme cuts DNA.

Moles of DNA ends =2x(grams of DNA)/(number of bp)(660 g/mol / bp).

The equation describes how many ends are produced when circular DNA is digested by a restriction enzyme.

Mole ends=2x(moles DNA)x number of restriction sites.

The following equation can be used to determine how many ends are produced during the digestion of a linear molecule by a restriction endonuclease.

Mole ends=2x(molesDNA)number of restriction sites +[2x(moles of DNA)].

What stage of respiration immediately follows the process depicted below? Two pyruvate molecules undergo a chemical reaction, co
Nadya [2.5K]

Answer:

Electron transport chain

Explanation:

Cellular respiration is the process whereby glucose is broken down in the cell to yield energy in form of ATP. This process, which is important to the metabolic functioning of every organism, occurs in three major stages namely: glycolysis, kreb's cycle and electron transport chain (ETC).

According to this question, a stage of respiration is described as follows:

- Two pyruvate molecules undergo a chemical reaction, combining with coenzyme A to form two acetyl-CoA molecules.

- Two carbon dioxide molecules and two NADH molecules are formed as a result of this process.

The process depicted above is KREB'S CYCLE of cellular respiration, hence, the stage of respiration that immediately follows the process is called ELECTRON TRANSPORT CHAIN (ETC).

Classify the planets based on their composition.
Darina [25.2K]

Answer:

Terrestrial  - Mercury, Venus, Earth, and Mars

Gas Giants  - Jupiter, Saturn, Uranus, and Neptune

Ice Giants - Uranus and Neptune

Explanation:

Gas plants are the planets that are composed mostly of the gases in them such as helium and hydrogen found in Saturn and Jupiter planets there are four planets known as the gas giants that are Jupiter, Saturn, Uranus, and Neptune. However, Uranus and Neptune planets are known as ice giants as these two planets are cold and remote and made up of completely different gases from the other two gas giants.

Terrestrial planets are the planets that are more rocky and compact in terms of their surface and these planets are inner planets of our solar system that are Mercury, Venus, Earth, and Mars.
