Answer:
This question lacks options, options are:
A.They maintain the cell’s shape.
B.They regulate cell processes.
C.They protect the body from infectious agents.
D.They signal the immune system to destroy pathogens.
E.They speed up biochemical reactions.
F.They send electrical signals.
The correct answers are C and D.
Explanation:
B cells and T cells use different biological weapons to attack the pathogen. The first secrete proteins called antibodies, which are distributed via the blood or the exposed surfaces to the environment, such as mucous. Antibodies are glycoproteins that circulate in the bloodstream looking for antigens that cause some type of damage to the body. Antibodies recognize and neutralize pathogens in a highly efficient way. Once the antibodies are produced, they remain circulating in the bloodstream for several months, which generates immunity for a long period of time to a certain antigen, in other words, they are capable of recognizing other molecules (antigens) in a very specific way and forming stable complexes with them (immune complexes). Its appearance in plasma is part of the adaptive immune response, in what is known as a specific humoral response, constituting a very effective defense against pathogens.
The balanced equation is
<span>8SO2 + 16H2S ----> 3S8 + 16H2O
</span>so
77g SO2 / 64g/mole = 1.203moles of SO2
<span>77g H2S / 34g/mole = 2.26moles of H2S
</span>now
<span>1.203 moles SO2 yields 3/8x amount that is = 0.456moles of S8
</span>so
<span>2.06moles H2S yields 3/16x amount = 0.386moles of S8
</span>hence
H2S = produce only 0.386moles of S8 = 98.98g S8
hope it helps
Answer:
The correct answer is option 3, that is, blastomeres.
Explanation:
A kind of cell formed by cleavage of the zygote post-fertilization is called a blastomere, it is an important constituent of blastula formation. The formation of blastomere starts instantaneously post-fertilization and is carried through the initial week of the development of embryo. The division of zygote after fertilization is regarded as the first mitotic outcome of the fertilized oocyte. These mitotic divisions take place spontaneously and lead to a grouping of cells known as blastomeres.
Answer:
The correct answer is biopsychosocial model.
Explanation:
An interdisciplinary model that provides an interrelation between the psychological, biological and socio-environmental elements is known as the biopsychosocial model. The model illustrates the facts that how the association between the mentioned factors plays an essential function in the fields of health and development of humans.
The model was postulated by George Engel in 1977 and is the first of its type to illustrate this kind of multidisciplinary thinking. However, the model has been rejected by many, but still, it has an influence in the fields of health, medicine, psychology, and the development of human beings.
