False, always wash it out.

Explanation:

Answer:

There is no such unique standard method—scientific progress requires many methods—but students in introductory science courses are taught that `The Scientific Method' is a straightforward procedure, involving testing hypotheses derived from theories in order to test those theories.

Explanation:

There is not a specific method. There are either 20 or 30 different ways you can do it.. I believe.

Make an observation, ask a question, form a hypothesis, make a prediction based on the hypothesis, test the prediction, make a new hypothesis based on the results.

The following occurs in meiosis but not in mitosis: pairs of homologous chromosomes are separated. This is present in the third option, and in the process, the homologous pair of chromosomes is separated in meiosis I.

Meiosis and mitosis share many similarities, such as replicated DNA separation, spindle fiber formation, and nuclear membrane fusion, but the difference between the two is that meiosis has homologous chromosome separation, whereas mitosis does not. The meiosis in this process makes four haploid cells, and the mitosis makes two diploid cells from a single daughter cell.

Hence, the following occurs in meiosis but not in mitosis: pairs of homologous chromosomes are separated. This is present in the third option, and in the process, the homologous pair of chromosomes is separated in meiosis I.

Answer:

chromotography: It is a process of quick and effective separation and purification of components of a combination. It bases its migration through a stationary phase, under the influence of a moving period, of the various components of the mixture.

Explanation:

How does chromatography work?

The same basic idea applies to all types of chromatography. The mobile phase, as its names suggest, is "mobile" and passes through a stationary phase. The different components of the mixture are divided between stationary and mobile phases, while the moving mobile phase passes through the stationary. This procedure allows components to be separated into a blend because the various components of the blend have various interactions with the mobile and stationary phases.

In reality, this means that in combination components that 'stick tighter' to the fixed phase remains in the fixed phase for a longer period. This means that the components in the mixture are separated, which are not 'strongly held' in the stationary phase. This is the basis of a separating technique for chromatography.

For instance, cotton wool or a glass fried sinter are placed at the base of a glass column in a simple liquid column chromatography system. The column then has a silica package. The column is packed in many ways, e.g. dry packaging or slurry. The crucial factor is that silica is well-packed without air bubbles or crashes, which prevents the movement of mobile phases. The mobile phase, often referred to as the eluent, is then added to reach the top of the silica, once the sílice is well packed. Following this, the mixture that is going to be separated is gently added to the top of the saturated silica. A layer of sand is then placed onto the mixture to ensure it is not disturbed by the addition of more eluent. The eluent (the mobile phase), which can be a solvent or mixture of solvents, is then continually introduced to the system until the mixture has been separated. It is crucial to make sure the eluent level never drops below the top of the silica to prevent air bubbles from entering the stationary phase and inhibiting mobile phase flow.

The components of the blend that "stands tight" in the steady phase (in this example silica) will stay longer in the column as the eluent is flushed down the column. Instead, components which do not 'close' to the stationary phase are faster to elute from the column and gather as fractions. It goes on until all the components have eluted individually from the column. The consequence is a separate mix.

Chromatography can work as a separation technique, as the stationary and mobile phasing attractions of distinct components in a mixture. Due to the varied qualities of the components in the combination, the different attractions are.

Silica, a stand-alone common phase, has Si-O-H connections on the surface. Si-o bonds and hydroxyl groups represent an extremely polar silica gel surface (stationary phase) able to form hydrogen bonds, and can also take part in the interactions of van der Waals, dipole–dipole and dipole–induced dipole.

As the complex mixture travels through the column, how quickly the various components of the elute from the column depend on two characteristics: 1) the degree of stabilisation of each chemical. The interactions between the various components and the silica gel depend on that. 2) How soluble in the mobile phase are the constituent components (the eluent). This relies on how the components interact with the solvent system.

While numerous components in a combination may be extremely similar and even possible to bind hydrogen to silica during the steady-stage stage, hydrogen binding on a silica is highly rare and will interact exactly the same way with the mobile phase. Co-elution (with multiple elements elucidating from the column concurrently) may occur in complex chromatographic separations. Different solvent systems and pH altering tests can even separate some of the most complicated blends into distinct components with the simple chromatography of the liquid column, by means of extensive and meticulous modification in the mobile phase.

glycolysis, kreb's cycle and electron transport chain

Explanation:

Answer:

Glycolysis, Krebs Cycle, Electron Transport Chain

Explanation:

Answer:

Moving the objects to one meter apart.

Explanation:

The gravitational force between tow objects is given by -

[tex]F=G\dfrac{m_1m_2}{r^2}[/tex]

Where

G is universal gravitational constant

r is distance between masses

It can be seen that the force will increase if we increase the masses or if we decrease the distance between masses.

Here, two objects are two meters apart. If the distance is decreased, the force will increase.

Here, out of 4 options, when the objects moves to 1 meter, the gravitational force will increase. Hence, the correct option is (c).

Cladistics refines classic taxonomy by linking organisms, based on the presence or absence of unique characteristics, into “grades.” For example, if three species share a suite of characteristics but only two of them have a particular trait that is not present in more distantly related species, those two are more closely related and would be depicted as a separate grade.
