Answer:
Mitosis, Meiosis, and both are written below
Explanation:
Mitosis: produces more somatic (body) cells, purpose is for healing and growing, the daughter cells are exact replicas
- This is because mitosis occurs in body cells and is used for growth, so all the daughter cells are the same.
Meiosis: results in sex cells (gametes), results in eggs and sperm, purpose is for creating new individuals (eventually), each daughter cell is different, has 2 separate division stages
- This is because meiosis occurs in gametes and is used in reproduction.
Both: Chromosomes need to replicate before the whole process begins, a form of reproduction
- This is because both are reproducing (they are dividing) and DNA must be replicated so each daughter cell has it.
Answer:
The correct answer will be option-
1. UV light strikes the skin and converts a steroid molecule into an inactive form of vitamin D.
2. Inactive vitamin D is transported to the liver where it is modified.
3. Vitamin D is activated under the influence of PTH.
4. Inactive, chemically altered vitamin D is transported to the kidneys.
Explanation:
Vitamin D is a fat-soluble metabolite which helps maintain the health of the bone by maintaining the calcium homeostasis.
The vitamin D is synthesized mainly in the liver and kidney from the biologically inactive precursor of vitamin D called ergocalciferol and Cholecalciferol.
The inactive vitamin is synthesized in the skin when the skin is exposed to UV rays. The UV rays convert the 7-dehydrocholesterol, a steroid molecule to Vitamin D3, This inactive vitamin is then transported to the liver where it is converted to 25-hydroxyvitamin D.
This vitamin D form is further metabolized in the kidney controlled and regulated by the Parathyroid glands.

Answer:
The correct answer is: a basement membrane.
Explanation:
The basement membrane is a thin and fibrous membrane that is found under the epithelium and<u> attaches it to the connective tissue</u>. The basement membrane is <u>composed of two membranes</u>: the basal lamina (with laminin and collagen IV, among other proteins), and the lamina reticularis (that has collagen III making up reticular fibers). The basement membrane also has the function of a <u>mechanical barrier that prevents the invasion of deeper tissues by malignant cells</u>.
Epithelial tissue and connective tissue are two of the four basic tissues found in the body (the other two are nervous tissue and muscle tissue). Epithelial tissue makes up the skin and the <u>inner lining of hollow organs</u> (like the stomach or the trachea), and has multiple functions that are responsible for the function of the organ where it's located. Connective tissue is basically any type of tissue that connects the epithelium to muscle tissue or nervous tissue: <u>from blood, to bone, and to fat</u>.
