Complete Question:
Which Kingdom of living things consists entirely of multi-celled, heterotrophic organisms?
A) Animal
B) Fungi
C) Plant
D) Protist
<u>Correct Option:</u>
<u>Animal</u> Kingdom of living things consists entirely of multi-celled, heterotrophic organisms.
Option: A
<u>Explanation:</u>
The system of scientific classification in biological science is categorized into seven main groups: kingdom > phylum > class > order > family > genus > species. Here the kingdom is the largest group while smallest is the species. The term phylum is being used in the Kingdom of Animals, and is the second largest group.
The Kingdom of Animals is made up of multi-cellular, heterotrophic species which feed on other entities to survive. Some of the animal properties in this kingdom are able to establish, function independently, and reproduce during their existence.
Explanation:
They would react the same as with the vinegar and hydrogen peroxide at room temperature. They would react the same as with just the hydrogen peroxide.
Step One - Obtain a clean microscope slide.
Step Two - Place a drop of liquid on the slide. This is the “wet” part of the wet mount. The liquid used depends on the type of cell being viewed:
If examining a plant cell, tap water can be used.
If examining an animal cell, physiological saline (or contact lens solution) must be used, because if plain water is used, the cell will explode from osmotic pressure. Unlike plant cells and bacteria, animal cells have no cell wall to structurally support them.
Step Three - Obtain the specimen to be used. Some introductory biology classics for viewing include:
Skin of an onion bulb: In order to view the cells, a very thin layer of skin must be obtained. Take a single layer of onion and bend it towards the shiny side. After it snaps, pull gently, and a transparent layer of skin, similar to Scotch tape, will appear.
Elodea leaf: Elodea leaves are two cell layers thick. The cells in one layer are smaller than the cells in the other, so elodea leaves can be used to better understand a microscope's depth of field.
Cheek cells: Human epithelial cells can be obtained by gently rubbing a toothpick on the inside of the mouth, and then swirling the toothpick in the physiological saline on the slide.
Pond water: Obtaining some water from a pond makes wet mount preparation a breeze, since the water and the specimens are both included.

Environmental scientists are using GPS ( It is effective but expensive) aerial monitoring (Quick but not the easiest), RFID tags, (mostly for long-term monitoring) and hidden cameras are used to study polar bear behavior without interruption to their environment.
