Explain how fertilizers can also pose respiratory dangers

Biology

Morgarella [4.7K]4 years ago

Although fertilizers are really helpful in maintaining the health and growth of crops or plants, because of its intrinsic chemical composition it can also be hazardous to a man's health. Respiratory disease associated with agriculture were one of the first recognized occupational hazards. Exposures to such may affect the airways that may result to asthma or asthma-like syndrome, and chronic obstructive pulmonary disease, which is practically dependent on the antigenecity or the ability to react with products of an immune response and host susceptibility. Inhalation of materials such  as fungal spores leads primarily to parenchymal dysfunction such as hypersensitivity pneumonitis.  Moldy hay, grain and similar organic materials has inherent endotoxins that may create a complex symptoms known as the ODTS or organic dust toxic syndrome which could represent a similar spectrum counterpart to hypersensitivity pneumonitis.

Why we used dyes when we prepare onion , human cheek eqithelium smears, and didn’t use it in cork and leaf epidermal cells smear
Ad libitum [116K]

Answer:

Explanation:

Staining is done for onion cells to visualize the cytoplasm of yellow and white onions because they are not pigmented. The staining of human cheek cells with methylene blue is necessary to stain the nucleus to get clear image of it under microscope because methylene blue binds to negative charge nucleic acids  

While for leaf epidermal cells smears, staining is not necessary as they are visible under light microscope without staining and they also have pigmented materials inside them such as chlorophyll chloroplast.  The cork cell is a non-living and have a cell wall whose structure is visible under light microscope.

Chickpeas are the third largest legume crop in the world and one of the eight founder crops of agriculture. Chickpea flower colo
WINSTONCH [101]

Answer and Explanation:

a. The enes are responsible for expressing the characteristics of an individual. However, genes responsible for the same trait have different alleles, which make these traits different from each other, as is the case with chickpea flowers. Alleles can be h0m0zygous dominant (AA), recessive h0m0zygous (aa) or heterozygous (Aa), in short, dominant alleles are expressed in capital letters and are always expressed by the organism, so the alleles with greater proportions within an intersection, since they can be expressed in h0m0zygous and heterozygosis. Recessive alleles, however, can only be expressed in h0m0zygous and therefore have a smaller proportion.

B. Chickpeas have a type of dominance called incomplete dominance. This type of dominance occurs when the dominant alleles (AA) do not suppress the expression of the recessive genotype (aa), but joins the one showing an intermediate phenotype to the phenotype of the two alleles. This recessive phenotype can be seen in the heterozygous allele (Aa). Thus, we can see that the dominant flowers have AA alleles and have a white phenotype, while recessive flowers have aa alleles and have a blue phenotype, as explained in the question above. The crossing between these two plants generates an offspring where all the flowers present the pink phenotype, which is the intermediate phenotype between blue and white, in addition, this crossing generated an offspring that presents the Aa phenotype. You can also see this variety of colors at the crossing of the F2 generation, where most plants have the intermediate phenotype (Aa), followed by the dominant phenotype (AA) and followed by the recessive phenotype (aa). All crossings can be seen in attachments.

c. To test the hypothesis of one or more genes responsible for these characteristics, we would have to do biochemical and molecular tests. For that, it would be necessary to make a DNA extraction from the plant, PCR reactions and the isolation of one or more genes related to the color of the flowers.
