Answer:
Both statements are true.
Explanation:
The simple columnar epithelium is characterized by presenting a single layer of cylindrical cells, with the basal and oval nucleus. This type of epithelium is found throughout the entire digestive epithelium, mainly on surfaces with high absorption power such as the walls of the small intestine, but they are also found on secretory surfaces such as the stomach walls, in the gallbladder, in some sections of the collecting tubes of the kidney, in the uterine tube (where it is ciliated) and in the uterus itself.
Squamous Stratified Epithelium is made up of basal cells that are cuboidal or columnar and metabolically active and superficial cells are flattened (squamous). Its function is to protect the underlying tissues in areas subject to nuclei abrasion, this epithelium (not keratinized) forms the wet surfaces of the basal esophagus, oral cavity and vagina. The oropharynx and the pharynx itself are lined by a stratified squamous epithelium as well.
ATPA molecule is a molecule that transfers energy from the breakdown of food molecules to cell processes

Ummmm…. can you elaborate on what it is ?
Answer:
The correct answer would be (D) Blue jays and finches nest in the same oak trees.
Competition is a type of ecological relationship between the organisms of the same or different species in which they compete for the same resources.
Limitation of any one resource used by both the organisms would become the limiting factor.
For example, blue jays and finches depend on the same oak tree for their nesting. Thus, limitation or decrease in the number of oak trees can become the limiting factor.
The air that we breathe is mostly made up of nitrogen (78%). 21% is oxygen which is needed for animals and humans in respiration and 0.03% is carbon dioxide which is needed for plants to make energy in a process called photosynthesis. The bit that is left is made up of rare gases like helium and argon and methane.
