Answer:

b) Have a variable region that can activate complement or attach to macrophages.

Explanation:

Antibody:

Antibodies are the part of immune system that is protein in nature and  produced to protect body from pathogens such as bacteria and viruses. These pathogens are recognized through the fragment antigen-binding variable region. Antibodies are also known as immunoglobulin.

Gamma globulins are the class of globulins, Antibodies are the most significant gamma globulins but it should be remember that some antibodies are not gamma globulins.

Correct Answer:

On the basis of above knowledge discussed the correct answer of this question is option b i.e Have a variable region that can activate complement or attach to macrophages.

Regarding cellular phones, the __________ is a code used to reset a forgotten pin.
tekilochka [14]

Regarding cellular phones, the <u>electronic serial number (ESN)</u> is a code used to reset a forgotten pin.

  • An electronic serial number (ESN) is the distinctive identification number that the manufacturer embeds or inscribes on the wireless phone's microchip.
  • The ESN is automatically sent to the base station each time a call is placed so that the mobile switching office of the wireless carrier can verify the legitimacy of the call. In the field, the ESN cannot be easily changed.
  • The mobile identification number (MIN), which is used by wireless carriers to identify phones on their network, is different from the ESN.
  • To aid in preventing fraud, MINs and ESNs can be electronically checked.

In Mendel's "Experiment 1", pea plants with smooth seeds intersect with pea plants with rough seeds. (smooth seeds is the dominant feature). Mendel collected the seeds of this cross, the plants and obtained the F1-generation of plants, let them self-pollinate to form a second generation, and analyzed the seeds of the F2 generation. The results they obtained; And the ones you would predict in this experiment are:

Guide

F1-generation plants

Mendel crossed SS (smooth seeds) with ss (rough seeds.)

All the gametes of parents smooth seeds, have the allele S (dominant) and all the gametes of parents rough seeds have the allele s (recessive). All the plants of the F1 generation will affect the Ss genotype (heterozygous), and all the seeds smooth seeds.

Generation-F2 plants

Mendel let the F1-generation plants self-pollinate to form a second generation and analyzed the seeds of the resulting F2 generation.

F2 generation    

All F1 hybrid plants have the Ss genotype and all are smooth (dominant characteristic). Recessive alleles are secreted during gamete formation. As a result, one in four possible combinations in F2 generation plants will have the recessive homozygous genotype (ss).
