Close examination of an organ reveals a lining of multiple layers of cells. The layers are avascular and regenerate well. One su
nevsk [136]

Answer:

Epithelial Tissue

Explanation:

The epithelial tissue can be classified according to the amount of layers, such as <u>simple epithelium</u> (formed by a single cell layer) or <u>stratified epithelium</u> (formed by more than one cell layer).

In addition, this tissue is avascular, in other words, it has no proper blood supply. Its nutrient transport usually occurs by <u>diffusion</u> through connective tissue.

The epithelium layers are able to regenerate quickly and easily when destroyed. Being a coating tissue, its cells have high healing power.

The epithelial tissue has two opposite sides, the outside of the epithelium(cavity), is known as the <u>apical surface</u>, and the inside is called the <u>basal surface</u> (this surface receives nutrients from the connective tissue by diffusion).

Cells on both surfaces are tightly connected, providing protection to the underlying connective tissue.

Finally, epithelial tissue also participates in the process of absorption of substances through the <u>intestinal epithelium</u>.

Explain why the scientists used the cytoplasm from the donors egg
gavmur [86]

It assures the insemination process because the cytoplasm contains the organelles ( mitochondria, Golgi apparatus, cytoplasmic reticulum etc. ). It is the go-between and transfers information between each organelles. Also, cytoplasmic transfer includes proteins, and mRNA along with the cytoplasm (and its organelles) to be taken from the donor egg.

A hypothetical organ has the following functional requirements: (1) the ability to resist surface abrasion and mechanical stress
alukav5142 [94]

Answer:

The <u>five</u> tissues needed that could make up this hypothetical organ are stratified squamous epithelial tissue, smooth muscle tissue, dense irregular connective tissue, loose connective tissue, and nervous tissue.

Explanation:

<h3 /><h3>Ability to resist surface abrasion and mechanical stresses</h3>

Stratified squamous epithelial tissue

This consists of <em>scale-like cells</em> stacked together in layers that provide a  <u>barrier that is resistant to abrasions and wear-and-tear</u>. This is also the most common type of stratified epithelium in the body. The top layer of this tissue has two types: <u>keratinized</u>, lined with dead cells with keratin, and <u>non-keratinized</u>, also with dead cells but without the keratin. In the human body, the skin is composed of stratified squamous epithelium.

<h3>Ability to contract involuntarily when stimulated by cells of the nervous system</h3>

Smooth muscle tissue

Smooth muscle, known for its <em>non-striated appearance,</em> is a kind of <u>involuntary</u> muscle cells that are <u>stimulated by neural signals by the autonomic nervous system, hormones, and local factors</u> such as a wall stretch of a certain organ, inflammation of visceral/parietal organs, etc. In the human body, this is mostly found in the <u>walls of blood vessels and organ systems.</u>

<u />

<h3>Ability to resist tension in many different planes of force</h3>

Dense irregular connective tissue

This is a kind of connective tissue made up of <u>collagen fibers arranged randomly.</u> This creates <u>greater strength and support in all directions</u>. It can also <u>return to its original shape</u> even after stretching.

<h3>One tissue to "glue" all other tissues together</h3>

Loose connective tissue

Also known as areolar tissue, it is loosely made up of collagen, elastin, and reticular fibers, and lots of ground substance. It is arranged in a web-like fashion and serves as the "cement" which fills in spaces between tissues.

<h3>One tissue to stimulate the contracting cells</h3>

Nerve tissue

It is a specialized kind of tissue responsible for communication within the body. It transmits and receives signal impulses throughout the body. The 2 types of nervous tissues are neurons and neuroglia.

Describe example of poaching that is prevalent in our area
melamori03 [73]
An example of serious poaching problems is the diminishing population of Tigers.
For example in India, this has severely affected the survival-probability of tigers. There were 20000 Tigers in India in the 20th century, and now there are only 3000. This shows the severity of the problem. The government is now taking serious steps against the poachers.
