Answer:
0.36g
Explanation:
Given parameters and conversion to standard unit
To solve this problem we must assume ideality
Volume of N₂H₄ = 350mL = 0.35dm³
Temperature of container = 50°C = 50 + 273 = 323K
Pressure = 885torr;
760torr = 1atm
885torr = 
= 0.86atm
Unknown:
Mass of the compound = ?
Solution:
The mass of the compound can be derived using the expression below;
Mass = number of moles x molar mass
molar mass of N₂H₄ = 2(14) + 4(1) = 32g/mol
To find the number of moles;
PV = nRT
n = 
P is the pressure
V is the volume
R is the gas constant = 0.082atmdm³mol⁻¹K⁻¹
T is the temperature
n = 
= 0.01mole
So,
Mass = 0.01 x 32 = 0.36g
Because viruses have the ability to infect cells. E.G a dendritic cell. So the only thing that can kill then are natural killer cells but then viruses reproduct in these cells
Answer:
B. Puerperium, or fourth trimester of pregnancy
Explanation:
- Puerperium or the fourth trimester of pregnancy is also known as the postpartum period.
- This period starts immediately after the mother gives birth to a child.
- During this period the size of the uterus and other reproductive organs along with the hormone levels return to their normal state.
- It is the phase where regression of all the anatomical and physiological changes that took place i in the reproductive organs of the females takes place.
- This phase is divided int three periods -
1. Immediate puerperium, or the first 24 hours after parturition
2. Early puerperium, which extends until the first week postpartum;
3. Remote puerperium, which includes the period required for involution of the genital organs and return of menses, usually approximately 6 weeks.
- This phase is highly critical for the mother as this requires rest and proper care as there are risks of bleeding. Therefore, the midwife or the nurse must take proper care of the mother.
Answer:
Promoter.
Explanation:
It is promoter because Promoter is a DNA sequence where's the gene transcription begins. It is the
DNA sequence which RNA polymerase binds or join to
so as to begin transcriptionn of a gene . It is a region where the regulatory elements i.e protein will bind to and the Promoter sequences are found directly upstream or at the end of 5' of the transcription initiation site. This can also encode RNA such as mRNA, trans and so on.
