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.
Independent Variable is what you change in an experiment. A Dependent Variable is what you’re trying to find out. Constants are what you keep that same. Control Group is the standards to which comparisons are made.
Answer:
Chromatin is a substance within a chromosome consisting of DNA and protein. The DNA carries the cell's genetic instructions. The major proteins in chromatin are histones, which help package the DNA in a compact form that fits in the cell nucleus. Changes in chromatin structure are associated with DNA replication and gene expression.
Explanation:
The answer should be NEURONES (nerve cells).
Neurons transmit electrical signals called NERVE IMPULSES from the cell body through the axon to the end plate. The junction between the end plate and the adjacent cell is called SYNAPSE. impulses passes through the synapse by diffusion of chemicals.
Answer:
r-selected species (e.g., American bullfrog)
Explanation:
The r-selected species (r-strategists) are those species in which their populations oscillate near the carrying capacity, i.e., the maximum population size sustained by a particular environment. These species are generally located in low-quality (less competitive) ecological niches and produce many offsprings that grow rapidly and have low chances of surviving to adulthood. Some examples of r-strategists include amphibians, fish, small mammals, etc. Conversely, K-selected species have more stable populations and produce a low amount of offspring (e.g., large mammals such as elephants).
