Answer is given below:
Explanation:
Function of vitamin C is healing wounds. Its deficiency causes multiple effects on connective tissue. It decreases the amount of collagen synthesis and angiogenesis and increases the amount of fibroblast and also increases capillary fragility and definitely because of its deficiency wound will not be healed properly or may not be healed.
Answer:
Endothelium provides a slick surface lining all hollow cardiovascular organs.
Explanation:
Endothelium is a layer made of cells that lines the interior surface of the entire circulatory system from heart to the capillaries. It forms the interface between the blood in the lumen and the vessel wall.
It is a single celled thin layer of squamous cells. It is involved in fluid filtration, maintaining the the blood vessel tone, homeostasis, hormone trafficking and neutrophil recruitment. It is of mesodermal origin. It is aligned in the direction of fluid flow.
Epithelia are layers of cells that line body surfaces and organs. Different types of epithelia have specific functions and structures. Simple columnar epithelium, stratified squamous epithelium, pseudostratified columnar epithelium, and endothelium are all examples of epithelial tissues.
Epithelia are layers of cells that line body surfaces and organs.
Simple columnar epithelium is a single layer of rectangular cells, commonly found in areas of absorption and secretion.
Stratified squamous epithelium is several layers of squamous cells, providing protection against abrasion. Pseudostratified columnar epithelium appears layered but is actually a single layer of cells, often found in the respiratory system.
Endothelium is a type of epithelium that lines blood vessels, providing a smooth surface and allowing for the movement of blood cells.

2. appears in a ratio of 2:1
3. appears in a ratio of 3:1
4. appears in a ratio of 2:2
Answer:
The correct answer would be 1. is always masked.
When homozygous or pure bred tall plant (TT) is crossed with homozygous dwarf or pure bred dwarf plant (tt), the offspring produced will always be heterozygus tall (Tt).
Thus, the recessive trait (t) dwarf is always masked by the dominant trait (T) tallness in F₁ generation.
