Simple epithelia have more layers for protection, whereas stratified epithelia allow materials to move across them and are less
xeze [42]

Answer: False.

Explanation:

Epithelial tissue is found in the linings of many structures throughout the body. There are two kinds of epithelial tissue: simple and stratified. And they  perform different functions and are structured differently.

The simple epithelium consists of one single layer of cells. In this way, all cells are in direct contact with the basement membrane and are separated from the connective tissue. The main function of this epithelium is <u>absorption and filtration.</u>

The stratified epithelium is composed of many layers of cells that are stacked together. In this way, this epithelium has the function of <u>protecting against physical and chemical damage.</u>

Ivenika [448]
I would tell the room mate  that what i just heard was the resemblance between the Fayum catarrhines and the Miocene proconsulids in skull form and dentition which suggests an evolutionary relationship, even if the direct fossils evidence is not present. Primates are divided into two groups; the prosimians and anthropoids. Monkeys evolved from Prosimians during the Oligocene Epoch while Apes evolved from the Catarrhines in Africa during the Miocene Epoch. Apes are then divided into the lesser apes and the greater apes.

9) Identify the FALSE statement regarding sensory receptor cells. A) A graded potential is referred to as a receptor potential.
rjkz [21]

Answer:

<u> C) Each type of sensory receptor responds only to the stimulus that defines the receptor</u>

<u></u>

Explanation:

Neurons,  specialized cells within the nervous system. These help with coordinated movement ad communication within the body through the transmission of electrical signals.

Sensory receptors are highly specialized neurons. These are able to detect various chemical and physical stimuli, and are classified by their ability to detect certain stimuli such as:

  • photoreceptors
  • mechanoreceptors
  • chemoreceptors
  • thermoreceptors

Sensory receptors respond to certain intensities of stimuli, instead of one specific stimulus. e.g. Mechanoreceptors within the skin can respond to pressure changes due to touch, but may also detect sound due to specific vibrations.

Rocks and Minerals as Resources Lab Activity
exis [7]

Mining is the birth of minerals and other geological accouterments of profitable value from deposits on the Earth.

  • Mining negatively affects the terrain by converting loss of biodiversity, soil corrosion, and impurity of face water, groundwater, and soil. Mining can also spark the conformation of holes. The leakage of chemicals from mining spots can also have mischievous goods on the health of the population living at or around the mining point.
  • In some countries, hidden-trapping companies are anticipated to cleave to recuperation and environmental canons to ensure that the area hidden-trapped is ultimately converted back into its original state. still, violations of similar rules are relatively common.

Loss Of Biodiversity

  • frequently, the worst goods of mining conditioning are observed after the mining process has desisted. The destruction or drastic revision of the pre-mined geography can have a disastrous impact on the biodiversity of that area. Mining leads to a massive niche loss for a diversity of foliage and fauna ranging from soil microorganisms to large mammals. Aboriginal species are most oppressively affected since indeed the fewest dislocations in their niche can affect extermination or put them at high threat of being wiped out. poisons released through mining can wipe out entire populations of sensitive species.

legislation related to mining-

  • There are different kinds of legislation. The legislation that needs land to be restored after mining tends to make mining to be veritably precious as it does so through the duty of some rules and regulations for the hidden-trapping companies.

  • Through this, it handles the responsibility of their land declination and takes back the land to its original form. This process is known to contribute to the fiscal counteraccusations of a company.

Why is it important to take land after mining?

Mining is known to be an act that disturbs the land. A lot of mines now are been known to reclaim the face in the course and after mining is completed, and therefore they return the land for useful purposes.

Reclaimed mine lands are known to be veritably beautiful and useful to wildlife and mortal uses.
