Epithelial tissue is composed of the innervated and avascular layer of cells which are tightly packed. It forms the outermost layer of the body and protects the internal layers and organs.
This tissue can be classified into different categories based on the shape of its cell, and the total number of the layers.
The epithelial tissue with only one layers is known as the simple epithelial tissue.
The epithelial cells that are thin, flat, and scaly are known as the squamous cells.
While the cubodial cells are round or square in shape.
Hence, the given blanks can be filled with classified, simple, squamous, and square.
A.Cladograms, because those are diagrams, all the rest contribute to natural selection.
Answer:
A major factor in determining the mode of nitrogen excretion is the availability of water in the environment. Generally, aquatic animals excrete mostly ammonia, whereas terrestrial animals excrete either urea or uric acid.
Explanation:
In the process of the nitrogen cycle. <span>
The nitrogen cycle is a biogeochemical succession process of nitrogen that involves: fixation, ammonification, nitrification, and denitrification. Like any other biogeochemical cycles. This process undergoes and affects the biological, geometrical and chemical aspects in the ecosystem and the abiotic and biotic community. Hence, the nitrogen cycle leads the abiotic component –nitrogen- to contribute to the biotic community, decomposition and primal production. Further, it becomes an essential part of the environment because some life components are contains it, similarly, amino acids, nucleic acids in RNA and DNA. </span><span> </span>
The answer is Iron, this is the important mineral that she
needs to obtain as this will help her in her ways to cardiovascular fitness as
this mineral helps the hemoglobin to build in her body and for her t be able to
