What if plants no longer existed on Earth? How would your life be different? Can you please answer in 125 words

If plants no longer exsisted on earth, we would be dead. We need plants to survive, they are our main source of oxygen and withought oxygen, humans die. But lets say that we didn't need oxygen to survive, just food. If we dont have plants we wouldnt have nutrients and our animals wouldnt have food. No plants, no food for cows or chickens to eat. Withought animals like that predators would also be starved because they have no food. So we have no food. So in conclusion, WE NEED PLANTS!!

1.) Librarians organize books according to a classification system. Describe another type of classification system you have seen

Answer and explanation:

<h3>1. Librarians organize books according to a classification system. Describe another type of classification system you have seen or used.</h3>

<u>Similar to the way librarians organize their books, taxonomists and biologists can classify living organisms</u>.

In terms of biology, the taxonomic categories of species is a system used to group different species according to their physical and functional characteristics and their phylogenetic relationship.

Taxonomy can classify living organisms into domains - according to their cellular characteristics, as well as placing them in Kingdom, Phylum, Class, Order, Family, Genus and Species.

For example, man (Homo sapiens) is classified, according to his taxonomy in:

<em>Domain: Eukarya. </em>
<em>Phylum: Chordata. </em>
<em>Class: Mammal. </em>
<em>Order: Primates. </em>
<em>Family: Hominids </em>
<em>Gender: Homo </em>
<em>Species: Homo sapiens. </em>

The taxonomic classification system is a way of establishing differences and similarities among living beings, as well as offering an approximation to their morphology and specific functions within nature.

<h3>2. Describe three examples of how are plants and animals different</h3>

Plants belong to the Plantae kingdom, while animals belong to the Animalia kingdom, and there are clear differences between them:

<em>Plants have no movement, while animals do. </em>
<em>Plant organisms are capable of processing their own nutrients (autotrophs), through sunlight, carbon dioxide, oxygen, water and inorganic nutrients from the soil. Animals (heterotrophic) require to obtain their nutrients by consuming plants or other animals. </em>
<em>In plants, plant cells have cloproplasts and chlorophyll, which are necessary for photosynthesis and to obtain energy substrate. The animal cell has mitochondria, which are in charge of cellular respiration, a process that provides them with energy. </em>

<h3>3. Describe three examples of how are plants and animals are similar</h3>

The similarities between plants and animals are based on the general characteristics of some living organisms:

<em>They are eukaryotic multicellular organisms, formed by biomolecules such as carbohydrates, lipids and proteins. </em>
<em>They have the capacity to reproduce and respond to stimuli. </em>
<em>The metabolic pathways to carry out their organic processes - such as obtaining energy - are similar.</em>

<h3>4. What are some differences between plants and fungi? What specific characteristics that you observed from this activity might help you classify this organism?</h3>

Some differences between plants and mushrooms are:

<em>Plants are photosynthetic organisms, capable of processing their own nutrients. Fungi require feeding on organic matter (heterotrophic). </em>
<em>The nutrition of plants is by absorption of inorganic nutrients from the soil, while fungi perform an external digestion process and then make the absorption. </em>
<em>From the cellular point of view, the wall of the plant cells is predominantly cellulose, while in the fungi the main component of the cell wall is chitin. </em>

An observable characteristic that allows us to establish the difference between plants and fungi is that plants are generally green, due to the presence of chlorophyll, necessary to carry out photosynthesis, while fungi are of variable colors, such as white, yellow, reddish or brown (they lack chlorophyll).

Describe the factors that affect saturation of water and the relative humidity in air

joja [24]

Answer: is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at a given temperature. Relative humidity depends on temperature and the pressure of the system of interest. The same amount of water vapor results in higher relative humidity in cool air than warm air. A related parameter is the dew point.

Name two features found in birds and their role in ensuring the ability to fly

mafiozo [28]

<h2>Answer:</h2>

There two features which facilitates bird <u>to fly are presence of light and smooth feathers and light bones</u>.

<h2>Explanation:</h2>

Birds are the only living creatures which has the ability to migrate from one place to another through flying. There are many physical features present in their body which facilitates them in flying.

<u>Among the two features and their role in flying are as follows: </u>

Light and smooth feathers: Wings are the organ which is involved in flying. It is composed of feathers which are very colorful and are light in weight and smooth in its appearance. This apart from reducing the body weight helps the bird to reduce the force and drag during flying.
Light bones: The skeletal system of the birds is composed of light bone which are primarily hollow with air sacs. This accounts for less body weight while flying.
