The matrix (inside mito) has a negative charge compared to the intermembrane space (outside of mito but still inside) because positively charged protons are constantly pumped from the matrix to the intermembrane space. A cell oxidizes an organic molecule producing 3 NADH molecules and 3 FADH2 molecules..
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.

Answer:
1. Many vertebrates have teeth, and chewing (mastication) breaks up food into small particles, expanding its surface and mixes it with fluid secretions, which makes it possible to digest. Teeth are located in the mouth of animals, where the digestive process initiates.
2. The stomach, which resembles a bag-like shape, can either fold up when empty and expand like a balloon when it fills up with food. By doing this, the area of activity of the gastric juice is expanded, increasing the efficiency of the digestion. Food enters the stomach from the esophagus.
3. The villi and microvilli present in the epithelial wall of the small intestine, are fingerlike projections that greatly enhance the surface area of the small intestine. In humans, this surface area is 300 square meters and it is over this large surface that the products of digestion are absorbed.
