B-Kidneys
The kidneys act as filters that strain urea and excess salts from the bloodstream to release them in the urine.
The cell membrane is composed of a phospholipid bilayer.
The cell membrane is primarily composed of a mix of proteins and phospholipids
Phospholipids are a major component of cell membranes. They a head and a tail. The head is hydrophilic (attracted to water) and the tail is hydrophobic (repelled by water).
They form a bilayer in which their hydrophilic heads face the aqueous cytosol and extracellular fluid while their hydrophobic tails face away from the cytosol and extracellular fluid.
The lipid bilayer is semi - permeable
Answer:
Predatory kills their prey on the spot. Parastic keeps the host alive and feeds off of thier body over a long period of time, until they are too weak to stay alive.
Explanation:
African fruit bats are likely involved in the spread of Ebola virus and may even be the source animal (reservoir host). Scientists continue to search for conclusive evidence of the bat's role in transmission of Ebola.
Answer:
1.6896 grams
Explanation:
Given that:
Total pressure = The pressure of 
+ partial pressure of 
∴
The pressure of = Total pressure - partial pressure of
= (754.8 - 17.55) mmHg
= 737.25 mmHg
At standard conditions:
1 mmHg = 0.00131579 atm
∴
737.25 mmHg will be: (737.25*0.00131579) atm = 0.970065928 atm
P ≅ 0.97 atm
The temperature (T) = 293 K
Volume (V) = 1.31 L
Using ideal gas equation
PV = nRT
0.97 × 1.31 = n × 0.0821 × 293
n = 0.0528
mass of oxygen = no. of moles * molar mass
= 0.0528 * 32
= 1.6896 grams
