Answer: B. They are a first line of defense that can begin killing pathogens immediately.
Explanation:
B-lymphocytes are not the first line of defense. On the contrary, innate immune cells such as basophils, dendritic cells, eosinophils, Langerhans cells, mast cells are the body's first line of defence.
<u>The equation that shows the decomposition of silver carbonate are;</u>
2Ag2CO3 ---------> 4Ag + 2CO2 + O2
<u>From the periodic table:</u>
Mass of silver = 107.8682 grams
Mass of carbon = 12 grams
Mass of oxygen = 16 grams
Molar mass of Ag2CO3 = 2(107.8682) + 12 + 3(16) = 275.7364 grams
<u>From the balanced equation above:</u>
2(275.7362) = 551.4728 grams<em> of</em> Ag2CO3 <em>produces</em> 4(107.8682) = 431.4728 <em>grams of Ag</em>
<u>Thus, in order to know the mass of Ag produced from 2.76 grams of Ag2CO3, we'll use the cross multiplication method; </u>
Mass of Ag produced = (2.76 × 431.4728) / (551.4728) = <em>2.16 grams</em>
Based on the calculations demonstrated above, the law of conservation of mass is applied.
I would believe that sugars and starches would have the most caloric value.
The correct answer is C. Dilation, strong contractions, and delivery of the baby and the placenta
Explanation:
Labor and delivery is divided into three main stages: the first stage includes the latent phase in which cervical dilation begins (3 to 5 cm) along with mild contractions and the active phase in which strong contractions occur along with complete or almost complete dilation; the second phase is the fetus expulsion or delivery in which the cervix is fully dilated and the baby is born; and the third stage is the delivery or expulsion of the placenta that occurs as the placenta separates from the uterus and is expulsed through mild contractions. Thus, stages of labor and delivery are dilation, strong contractions, and delivery of the baby and the placenta.
