To detect immunoglobulin m (IgM)antibodies in an acute phase, blood should be collected 7 days after the onset of infection.
- IgM and IgG antibodies to SARS-CoV-2 may both be found shortly after infection. IgG is typically detectable for extended periods of time, but IgM is most effective for diagnosing recent infection and typically becomes undetectable weeks to months after infection.
- IgM antibody detection is frequently viewed as a sign of an acute infection. Due to cross-reactivity with IgM antibodies to other, closely related bacteria or other interfering chemicals, false-positive IgM findings are, nonetheless, frequently observed.
- A positive IgM result may not always indicate an "acute" infection, and additional testing (such as IgG testing) may be required to interpret results because IgM antibodies may be detectable for 2-4 months (or longer) after disease resolution.
- For many infections, the onset of a measurable antibody response is 5-7 days after the infection. If samples are taken before infection, the initial IgM test results may be negative. Antibody production Immunosuppressed patients may also continue to be seronegative.

Answer:
mediante la absorción, por la raíz
Explanation:
Answer:
<em>Water will move out of a cell.</em>
Explanation:
A hypertonic solution will have higher solute concentration and lesser solvent concentration. If a cell is placed in such a solution, then the concentration of the solvent will be more inside of the cell as compared to outside of the cell. As a result, the solvent will move out of the cell. If an excess of solvent is lost, the cell might shrink to dangerous levels.
Hence, from the above description we can justify that water will move out of a cell which is placed in a hypertonic solution.
co-dominance is the answer because
Inheritance of Dwarfing in Maize. Demonstrating the heights of plants from the two parent variations and their F1 heterozygous hybrid (centre).
Dominance in genetics is a relationship between alleles of one gene, in which the effect on phenotype of one allele masks the contribution of a second allele at the same locus.[1][2] The first allele is dominant and the second allele is recessive. For genes on an autosome (any chromosome other than a sex chromosome), the alleles and their associated traits are autosomal dominant or autosomal recessive. Dominance is a key concept in Mendelian inheritance and classical genetics. Often the dominant allele codes for a functional protein whereas the recessive allele does not.
