What aspects do all chromatography experiments have in common?

1 answer:

7 0

Answer: The aspects that is common in all the chromatography is that all the chromatography has a mobile phase and a stationary phase.

Explanation:

The chromatography can be defined as a separation technique of the mixture. The mixture in the fluid is the mobile phase and the structure holding the material is the stationary phase.

The separation is based on the differential partitioning between the stationary phase and the mobile phase.

This technique is also helpful in removing the impurities from the substances.

" A single gene produces two different proteins, utilizing different exons. Produce the explanation"

bezimeni [28]

Answer:

Explanation:

Exons can be shuffled independently known as exon shuffling. It can be done in various ways, leading to infinite number of combinations to discover new and meaningful coding sequences hence various proteins. Due to exon shuffling, evolution need not occur only by the slow accumulation of point mutations but might also move ahead by “quantum leaps” with new proteins appearing in a single generation.

Describe all muscle tissues, including cell shape, layers, intercellular connections,

zmey [24]

<h2>Description of muscle tissues. </h2>

Explanation:

There are three types of muscle tissue are cardiac, smooth, and skeletal.

1. Cardiac muscle tissue: It is located in the walls of the heart.

They appear striated.

Control is involuntary.

Function: To pump blood through the blood vessels in your body.

2. Smooth muscle tissue: It is located in walls of hollow visceral organs, except the heart.

They appear spindle-shaped.

Control is involuntary.

Function: To move food through the digestive tract.

To regulates air flow in lungs.

3. Skeletal muscle tissue: It occur in muscles which are attached to the skeleton.

They appear striated.

Control is voluntary.

Function: To support the body.

It makes bones and other body parts move.

Cell shape : There are different shapes of cells which are as follows:

1. Squamous 2.Cuboidal 3. Columnar 4. Polygonal 5. Stellate

6. Spheroid 7. Discoid 8. Fusiform 9. Fibrous.

Muscular layer: The muscular layer is present in many organs in the vertebrate body.

It is responsible for peristaltic movement in body.

There are two layers of muscle.

1. Inner 2. Outer layer.

Inner layer: The muscle of the inner layer is arranged in circular rings around the tract.

Outer layer: the muscle of the outer layer is arranged longitudinally.

Intercellular connections or junctions: These are the structures which provide adhesion and communication between cells.

There are mainly three types of junctions:

1. Tight junctions: It help to stop substances from leaking across a tissue.

2. Adhering junctions: It perform the function of cementing so as to keep neighbouring cells together.

3. Gap junctions: It facilitate the cells to communicate with each other by connecting the cytoplasm of adjoining cells, for rapid transfer of ions, small molecules and sometimes big molecules.

What elements and compounds are in the water cycle?

pashok25 [27]

Answer:

All chemical elements that are needed by living things are recycled in ecosystems, including carbon, nitrogen, hydrogen, oxygen, phosphorus, and sulfur. Water is also recycled.

Of the many processes involved in the water cycle, the most important are evaporation, transpiration, condensation, precipitation, and runoff

Earth’s water is constantly in motion. Although the water on Earth is billions of years old, individual water molecules are always moving through the water cycle. The water cycle describes the continuous movement of water molecules on, above, and below Earth’s surface. Like other biogeochemical cycles, there is no beginning or end to the water cycle. It just keeps repeating. During the cycle, water occurs in its three different states: gas (water vapor), liquid (water), and solid (ice). Processes involved in changes of state in the water cycle include evaporation, sublimation, and transpiration.

How does the gene flow affect neighboring populations

Nimfa-mama [501]

The movement of alleles from one population to another is called gene flow. Other alleles will likely increase in frequency and become fixed. These changes in allele frequencies that are due to chance are called genetic drift. Genetic drift causes a loss of genetic diversity in a population.

trapecia [35]

The ecosystem-based fishery management approach views the entire ecosystem as relevant to managing a fishery and allows for the diverse societal uses of fish stocks, including fishing, recreation, tourism, and overall ecosystem health.

The ecosystem-based management of fisheries is an approach, which projects a holistic outlook towards the management of fisheries in such a way that, humans can benefit from in numerous ways like fishing for food or recreation, or for breeding new stocks of fish. All this is done keeping in mind the angle of environment and biodiversity conservation of the area as well. This approach is extremely essential to keep a check on the effects of human intervention in the ecosystem of the fisheries and how to maintain a stable balance between the two without harming the latter.
