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.

In the complete oxidation of glucose, six CO2 molecules are formed per glucose molecule. The number of CO2 molecules released by
Serga [27]

Answer:

0, 2, 4

Explanation:

The process of cellular respiration takes place in for phases which oxidizes the glucose molecule to the provide energy molecule called ATP.

Along with ATP, the process releases the metabolic water and carbon dioxide gas. In the oxidation of one glucose molecules, about 6 molecules of CO₂ are released. These CO₂ molecules are produced in the following manner:

1. Glycolysis: CO₂ gas is not produced during this reaction but only ATP and NADH are produced.

2. Pyruvate decarboxylation: the process converts the pyruvate produced by glycolysis to Acetyl-CoA. Formation of 1 Acetyl-CoA produces 1 CO₂ and since 2 Acetyl-CoA is produced therefore produces 2 CO₂ molecules.

3. Citric acid cycle: The cycle converts 2 Acetyl-CoA and produces 4 CO₂ in two cycles converting each Acetyl-CoA.

Thus, 0, 2, 4 is correct.
