Once infected cells have sensed an invading pathogen, they secrete molecules called cytokines and chemokines. Cytokines such as interferons are molecules that signal neighbouring cells and induce an antiviral state in them. These cells are then primed to resist an infection with the invading virus.
Answer:
0.2558 g
Explanation:
1.- In titration, since you have the concentration and the volume of the titrant and the aliquot that you take, you can use the formula C1 V1 = C2 V2.
2.- To obtain C2 = C1 V1 /V2
Substitution C2 = (0.0149 M ) (9.75 ml) /25 ml = 0.0058 11 M
3.- This concentration is the number of moles that you would have in 1 L but you dissolve your tablet in 250 ml, so a rule of three.
4.- 0.005811 moles - 1 L
x - 0.250 L
X= 0.250 L x 0.005811 moles / 1L = 0.00145275 moles
5.- using your molecular weight, you can obtain the grams with another rule of three.
0.00145275 moles - x
1 mole - 176.12 g
x= 176.12 g x 0.00145275 moles / 1 mole = 0.2558 g

Answer:
Hypothermia is being really cold and hyperthermia is being really hot
Explanation:
Answer:
The correct option is: c. human chorionic gonadotropin (hCG)
Explanation:
Human chorionic gonadotropin is a glycoprotein, secreted by the syncytiotrophoblast cells of the placenta during early pregnancy. The human chorionic gonadotropin hormone is produced after the implantation to maintain the viability of the corpus luteum during the first trimester of the pregnancy. The presence of this hormone can be detected by some pregnancy tests.
Depending on there condition, if it’s extremely bad you should start cpr and chest compressions but if you have time hook up the aed and get help on the way.
