Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth.

Plants are involved with the carbon cycle because they go through a process called photosynthesis. Photosynthesis is when the plant absorbs carbon dioxide(CO2) and releases oxygen, this is for the plant to grow and live. This is very good for our environment and keeping the air clean.

Consider the diagram of the basic structure of a bacterium.
olga_2 [115]

Answer:

There is no diagram but the needed information has been provided. The answer is:

Part C

Explanation:

The bacteria is a prokaryotic living organism in the domain Bacteria. It is pretty because it lacks a membrane-bound nucleus that houses its genetic material (DNA), instead its circular chromosome is found naked in a region of the cytoplasm called NUCLEOID. The nucleoid region contains the genetic material of the bacterium cell.

Since bacteria reproduces asexually, which does not allow diversity among species, bacteria ensures they promote genetic recombination by exchanging their genetic material in three ways: Transduction, Transformation and Conjugation. This genetic recombination causes them to be better pathogens and improve their resistance. However , since the exchange involves the genetic material (DNA), it is only natural that it involves the region where it is found, which is the NUCLEOID.

Describe the process of chromatographic separation. You need to include both the equilibrium model to predict retention times an
Kay [80]

Answer:Chromatography is actually a way of separating out a mixture of chemicals, which are in liquid or gas form, by letting them flow slowly past another substance, which is either a solid or a liquid. It consist of a stationary phase and a mobile phase.

Explanation: All chromatographic systems rely on the fact that a substance placed in contact with two unmixable phases, one movable phase and one stationary phase, will equilibrate between them. A selectivity (or separation) factor (α) is used to 'chemically' distinguish between sample components. It is usually measured as a ratio of the retention (capacity) factors (k) of the two peaks in question and can be visualized as the distance between the apices of the two peaks. reproducible fraction will partition into each phase, depending on the relative affinity of the substance for each phase. A substance which has affinity for the moving or mobile phase will be moved rapidly through the system. A material which has a stronger affinity for the stationary phase, on the other hand, will spend more time immobilized in that phase, and will take a longer time to pass through the system. Therefore, it will be separated from the first substance. By definition, chromatography is a separation technique in which a sample is equilibrated between a mobile and a stationary phase. A theoritical plate or tray is used to produces the best possible difference between the liquid and vapour phases in equilibrium with it

Chromatographic separations are best done with a small amount of analyte (substance to be separated during analysis), which keeps either phase from becoming saturated with analyte, so that the concentrations in the two phases are directly proportional. Overloading the column with sample causes one of the phases to become saturated, leading to a loss of column efficiency, and poorly shaped peak profiles.

The retention volume in chromatographic separation (Vr) is the volume of the mobile phase required to carry the solute through the column to elution, is related to the column flow (Fc) and the retention time (tr). Likewise, the volume of the mobile phase(Vm), is related to the flow and the time the void volume takes to pass through the column.

Band broadening using the kinetic model is a phenomenon that reduces the efficiency of the separation being carried out, leading to poor resolution and chromatographic performance. This is problematical in terms of both the quality of the separation obtained and the accuracy with which sample components can be quantified.The wider band results in a dilution effect that produces a decrease in peak height accompanied by a loss in sensitivity and resolution. The eddy dispersion, accounts for the source of band broadening related to any flow unevenness in the column.

PLEASE HURRY! what is the best decription of chromosomes by the end of metaphase 2 of meiosis?
Oksi-84 [34.3K]

The best description of chromosomes by the end of metaphase 2 of meiosis is that they are lined up in the middle of the cell. You can help remember this by thinking of the "M" in metaphase as middle. this is because in this phase the chromosomes are lined up in the middle of the cell.

Roman55 [17]

Answer:

Basal cells, keratinocyte

Explanation:

The viral DNA replication is inhibited until<u> Basal cells</u>  are differentiated into <u>keratinocyte</u>, which are ready to be shed from the epithelial layer, increasing the likelihood that HPV will be transmitted to a new host.

95% of the cells in the epidermis are keratinocytes

Basal cells are multipotent stem cells that are important in the regeneration of homeostasis of the respiratory epithelial cell population.

in skin growth, most of the cells are keratinocytes and they are formed by the division of stem cells in the basal layer
