Well, leukocytes and white blood cells are the same thing, and they have a nucleus so you cant rule those out. Nerve cells also have a nucleus that contains genes.. in that case, the answer is <span>erythrocytes.</span>

Answer: erythrocytes

Erythrocytes also called as red blood cells. These are the cells which does not possess nucleus. They exhibit a pigment named as hemoglobin, the heme  component of the hemoglobin has affinity for oxygen. It carries oxygen to all the parts of the body.

Initially the red blood cells are produced in the bone marrow with a nucleus. These red blood cells undergoes a process called as enucleation, this results in the removal of the nucleus from the cells. This process occurs when the cells attains maturity. It is a kind of adaptation that occurs in the red blood cells.  It allows red blood cells to carry more hemoglobin, thereby carrying more oxygen molecules. It allows the cells to have distinctively bi- concave shape, which facilitates diffusion of carbon dioxide and oxygen. This could not be possible in the presence of nucleus.

To detect immunoglobulin m (igm)antibodies in an acute phase,blood should be collected in _____ days after the onset of infectio
Gnom [1K]

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.

The gene for hairline shape has two alleles: widow's peak (W) and straight hairline (w). What is the percent probability that on
Alexandra [31]

Answer:

Probability of having a child with genotype Ww is 50%.

Explanation:

This question involves a single gene coding for hairline shape in humans. The allele for widow's peak hairline (W) is dominant over the allele for straight hairline (w). This means that allele W will mask the phenotypic expression of allele w in a heterozygous state.

In a cross between a mother with genotype, Ww and father with genotype, ww, the following gametes will be produced by each parent:

Mother (Ww)- W and w

Father (ww)- w and w

Using these gametes in a punnet square (see attached image), four possible offsprings will be produced with genotypes: Ww, Ww, ww and ww.

Ww(2) : ww(2) or Ww(1) : ww(1)

Hence, 1 out of 2 children produced by the parents will have a genotype Ww, i.e. 1/2. Therefore, the percentage probability is 1/2 × 100= 50%.
