The picture below shows xylem and phloem vessels, which are tube-like structures in a plant's roots and stems. Phloem is adapted for
transporting the glucose made during photosynthesis to the roots and
stems.

c. tetragonal
d. orthorhombic
Answers
Answer:
B- Tetraclinic
Explanation:
According to the similarity of their symmetry elements, thirty-two classes are grouped into seven crystal systems: isometric (cubic) system, tetragonal system, hexagonal system, trigonal system (subdivision of the hexagonal system, second North American school of crystallography). , called rhombohedral hexagonal system), orthorhombic system, monoclinic system and triclinic system. Applying the symmetry operations on all possible reticular planes (potential crystal faces) in the seven crystalline systems, according to the 32 symmetry classes, only 48 geometric shapes are possible to be obtained.
Tetraclinic is not one of the seven types of crystal.
Seven types of crystals
The seven types of crystal are triclinic, monoclinic, orthorhombic, tetragonal, trigonal, hexagonal, and cubic while on the other hand, triclinic system is one of the structural categories in which crystalline solids can be assigned.
So we can conclude that Tetraclinic is not one of the seven types of crystal.

The elements that accept the electron of Lithium are Fluorine, Chlorine, Bromine, and Iodine.
Metals and nonmetals are the elements in the periodic table that gains and lose electrons to form chemical bonds.
The metals are a compound that loses electrons and nonmetals gains electrons to form a chemical bond.
Elements bonding with Lithium
Lithium has been a group 1 element with 1 valence electron. It has been bonding with the nonmetals that accept the electrons and form the bond. The elements complete their octet and become stable.
The nonmetals that require an electron to complete their octet are halogens. Thus, the elements that accept the electron of Lithium are Fluorine, Chlorine, Bromine, and Iodine.

# moles = mass / molar mass
Molar mass calculation
Barium hydroxide = Ba (OH)2
Atomic masses
Ba = 137.4 g/mol
O=16 g/mol
H=1 g/mol
Molar mass of Ba (OH)2 = 137.4 g/mol + 2*16g/mol + 2*1 g/mol = 171.4 g/mol
# mol = 25.0g/171.4 g/mol = 0.146 mol
For the volume of water use the fact that the density is 1g/ml., so 120 g = 120 ml = 0,120 liters.
M = 0.146mol / 0.120 liters = 1.22 mol/liter

pOH = -log(8.6 x 10 ^-5)
pOH = 4.07
To calculate the pH we use the relation of pOH and pH, expressed as:
14 = pOH + pH
pH = 14 - 4.07 = 9.93
pH = -log [H+]
[H+] = 10^-9.93 = 1.16 x 10^-3 M
