The biological molecules that transport other substances are the proteins.
<h3>What are proteins?</h3>
Proteins are biological macromolecules that contains nitrogen in their molecules and are the building block of a living organism.
The proteins perform the following functions:
- they transport other substances,
- provide structural support,
- cause the movement of muscles, and
- catalyze chemical reactions in living organisms.

Answer:
Explanation:
Communicating junctions or gap juctions consider direct substance correspondence between contiguous cell cytoplasm through dispersion without contact with the extracellular liquid.
C = n/V
n = C×V
n = 4,41M × 1,25L
n = 5,5125 mol
mKI: 39+127 = 166 g/mol
1 mol --------- 166g
5,5125 mol --- X
X = 166×5,5125 = 915,075g KI

Answer: option A. Cobalt
Explanation:
1) Data:
Q = 1.24 × 10⁶ J
m = 2 kg
Tf = 1768 K
Ti = 298 K
Cs = ?
2) Formula:
Q = m Cs ΔT
ΔT = Tf - Ti = 1,768K - 298K = 1,470K
3) Calculations:
i) Solve for Cs:
Cs = Q / [ m ΔT]
ii) Substitute the data:
Cs = 1.24 × 10⁵ J / [ 2kg (1768K - 298K) ] = 421 J / (kg K)
4) Compare with the specific heats (Cs) of the vaious metals given and you find that it is Cobalt.
All isotopes have the same number of protons and the same number of electrons. Because the electron structure is the same isotopes have the same chemical properties.
