Answer: B. They reproduce slower than unicellular organisms
Explanation:
In unicellular organisms there is a single cell which performs all the functions like digestion, respiration, and reproduction. The cell reproduce by cell division. The single parent cell divides into two identical daughter cells. But multicellular organisms exhibit multiple cells and their reproduction is complex. They reproduce by sexual mode of reproduction in which separate sex cells are produced when they fuse form zygote which is the precursor of new organism. This process is slower than that of the cell division and production of progeny by the unicellular organisms. Thus reproduction is slower in multicellular organism this is the disadvantage in multicellular organisms.

From the Ideal gas law (Combined gas law)
PV/T = P'V'/T' .....eq 1
Where:
P - initial pressure
V - initial volume
T - initial temperature
P' - final pressure
V' - final volume
T' - final temperature.
To proceed we have to make T the subject from eq.1
Which is, T = P'V'T/PV.......eq.2
We have been provided with;
Standard temperature and pressure (STP)
P = 760 mm Hg (SP - Standard Pressure)
T = 273.15 K (ST - Standard Temperature)
V = 62.65 L
P' = 612.0 mm Hg
V' = 78.31 L
T' = ? (what we require)
Therefore, we substitute the values into eq.2
T' =
.
T' = 275.60 K
T = (275.60 - 273.15) ......To °C
T = 2.45 °C

Have a nice studies.
Answer:
The answer to your question is: letter A
Explanation:
a. Ribonucleotides have a hydroxyl group on the 2 carbons of their sugar sub-unit. This is the main difference between Ribonucleotides and deoxyribonucleotides, the first have hydroxyl group in carbon number two, while the second have a hydrogen.
b. Ribonucleotides contain a phosphate group.
c. Ribonucleotides have a hydrogen atom on the 1 carbon of their sugar sub-unit.
d. Ribonucleotides contain a sugar with five carbon atoms.
A. Heat is released, so the reaction is <u>exothermic</u>.
B. Heat is absorbed, so the reaction is <u>endothermic</u>.
C. Heat is released, so the reaction is <u>exothermic</u>.
The answer is a. Cluster. Because they contain ten to thousands of individual galaxies.
