According to size, the molecules that enter the gel will separate. Because they do not need to squeeze through the gel's pores as much as the larger ones do, the smaller ones will travel further down the gel.

A laboratory procedure called electrophoresis is used to divide DNA, RNA, or protein molecules according to their size and electrical charge. Colloidal particles migrate during electrophoresis under the influence of an applied electric field. In cataphoresis, negatively charged particles move away from the anode while positively charged particles move closer to it (anaphoresis). Colloid particle charges can be determined via electrophoresis.

The phenomenon that most biomolecules exist as electrically charged particles with ionizable functional groups serves as the foundation for electrophoresis. At a specific pH, biomolecules can exist as either positively or negatively charged ions in a solution. The technology of electrophoresis is crucial for the separation and examination of nucleic acids. At the lab bench, cloned DNA fragments are frequently isolated and worked with using nucleic acid electrophoresis.

The last phase of the Calvin cycle is called the "regeneration phase" or the "reductive phase."

The Calvin cycle, also known as the carbon fixation cycle or the dark reaction of photosynthesis, is the process by which plants use energy from sunlight to convert carbon dioxide (CO2) into glucose and other sugars. The cycle is named after Melvin Calvin, who was awarded the Nobel Prize in Chemistry in 1961 for his work on the cycle.

The last phase is called the "regeneration phase" or the "reductive phase" wherein the Calvin cycle regenerates the CO2 acceptor (RuBP) using the products of the previous stages, CO2 and NADPH, so that the cycle can continue. This phase is also when the CO2 is fixed and the cycle produces G3P, a 3-carbon molecule which can be used to make glucose or other sugars by plants.

Net charge describes the overall negative or positive charge of an atom or compound. Also, note that it is common in chemistry to write the sign of the charge after the number. Nevertheless, the charges +1 and 1+ are completely the same.

Calculating Charge

To find the charge of an atom you should look at the number of protons and electrons. Since neutrons have a neutral charge, aka no charge, they do not factor into net charge. On the other hand, protons have a positive charge and electrons have a negative charge. Each proton has a 1+ charge and each electron has a 1- charge.

To find the net charge find the total charge of the electrons and the total charge of protons, then add them together. Since there are 9 protons, the total proton charge is 9+. There are 11 electrons, so the total electron charge is 11-. For the purposes of doing the math, we can move the sign to the front.

Thus, the net charge is 2-.

Anions and Cations

To work with ions it is important to understand the vocabulary surrounding ions. Firstly, negative ions, like the one described in the question, are called anions. You can remember this as "A Negative ION". Also, positive ions, ions with positive net charges, are called cations. You can remember that the "t" looks like a plus sign.

Natural selection is a process by which organisms that are better adapted to their environment tend to evolve new traits.

In general ,Natural selection is considered as the process through which organisms develop variation in traits, which make them more fit to survive in changing environment survival. Thus , Natural selection primely depends on the environments. Natural selection doesn't depend on the traits that are genetically superior natural trait but they acts on existing heritable variation . These Heritable variation comes from random mutations.

Answer:

Please read below:

Explanation:

Photosynthesis is the process by which plants, algae, and some bacteria capture energy from sunlight and use it to produce food (sugars) from carbon dioxide and water. During photosynthesis, oxygen is also released as a by-product. Examples of photosynthetic organisms include plants, algae, and some bacteria.

Cellular respiration is the process by which cells break down food molecules to produce energy, which is then used to power the cell's activities. It involves the conversion of the chemical energy stored in carbohydrates, fats, and proteins into a form of energy that can be used for cellular activities. Examples of cellular respiration include glycolysis and the Krebs cycle.

Photosynthesis and cellular respiration are connected in that they are part of a cycle of energy exchange between plants and animals. During photosynthesis, plants use energy from the sun to convert carbon dioxide and water into oxygen and glucose.

During cellular respiration, animals use oxygen and glucose to produce energy and carbon dioxide. Plants and animals benefit each other in that plants use the carbon dioxide produced by animals to perform photosynthesis, and animals use the oxygen produced by plants for respiration. In this way, plants and animals form a mutually beneficial cycle of energy exchange.

Answer:

  B. Cool water flows in to take its place

Explanation:

You want to know what happens when warm water rises in the ocean.

In any fluid, currents will arise from differences in fluid density. When fluid moves out of a space, other fluid flows into that space to fill the void.

In general, ocean currents arise from differences in temperature and salinity. Warmer and less saline (fresh) water have less density than colder or more saline water. As a consequence of its reduced density, warmer (or less saline) water will experience pressure moving it upward. It is replaced by water of lower temperature or greater salinity.

When warm water rises, cool water flows in to take its place.

Explanation:

The data suggest that Turtles are less evolutionary related to humans when compared to chimpanzees and closer compared to tunes since amino acid differences account for the term divergence between species.

The term divergence between species in evolution makes reference to the difference between species in a given homolog protein sequence and or any other feature derived from a common ancestor. In this case, we can see that the aminoacid differences are higher between humans and tunas, thereby these species are evolutionary distant when compared to chimpanzees and also compared to humans and turtles (mammals and reptiles are evolutionary closer compared to tunas).

Therefore, with this data, we can see that the term divergence between species is based on the presence of homologies between individuals due to a common ancestor such as occurring between species.
