The empirical formula is the simplest whole number ration that defines constituent atoms in a species. The molecular formula is always a multiple of the empirical formula.

Molecule Formula = 78.0 • g • mol ^ -1 = n(12.011 + 1.00794) • g • mol ^ -1

78
N = ——————————- = 6
12.011 + 1.00794

Molecular Formula = C6H6

Capillaries surrounding the brain have no pores and are surrounded by membranes of astrocyte cells because

Capillaries are tiny blood vessels in the circulatory system that connect aterioles to venules. They are the most abundant or they are much blood vessels. They can penetrate the tissues of the body which allow passage of food nutrients, oxygen in the body thereby allowing exchange of nutrients and oxygen between the body tissues and the blood.

A daughter cell that matures to the inside of the vascular cambium becomes ______, and a daughter cell that matures to the outsi
melomori [17]

A daughter cell that matures to the inside of the vascular cambium becomes<u> secondary xylem</u> and a daughter cell that matures to the outside of the vascular cambium becomes <u>secondary phloem.</u>

<u />

  • The cambium divides its cells to create secondary xylem and phloem. As secondary phloem and xylem tissue builds up, the stem becomes thicker and develops wood and bark.
  • The kind of xylem produced by secondary growth is known as secondary xylem. In contrast, during primary growth, the primary xylem develops.
  • As a result, lateral growth, as opposed to vertical growth, is connected with the secondary xylem, as opposed to the primary xylem.
  • The procambium, which is found between the xylem axis and the phloem pole, develops into the cambium in the root.
  • A pattern resembling the arrangement of secondary stem is produced when xylem forms in the core and phloem on the perimeter of secondary development.
