Which structure is often modified to attract pollinators?

What are the benefits to the host of diplomonads?

7nadin3 [17]

Answer: C) the parasite benefits, and the host is harmed; however, the host is not generally killed.

Killing the host would be bad for the parasite, as it would have no place to live.

Which of the following types of passive transport involves the movement of molecules via special transport proteins? A. facilita

FrozenT [24]

Answer:

A

Explanation:

There are different mechanisms for transport of molecules across the cell membrane. One kind of this transport is facilitated diffusion, this is a form of passive transport, not requiring any ATP (the opposite would be active transport, where it does require ATP.

Simple diffusion does require special transport proteins, and neither does osmosis. Filtration is a technique used for sterilisation of water, where any impurities can be drawn out of the liquid

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.
