Can organisms create their own energy? Explain your answer

1 answer:

7 0

<span>NO
In many functions of a living organism, it cannot make its own energy. It uses energy from its environment, retrieves and converts into a usable and edible matter. Organisms that can do this process is the autotrophs, they can facilitate photosynthesis which they gather energy from the sun, water and carbon dioxide in order to create energy by then, the transfer of this energy to other organism is played by the food chain –food web. </span>

G separation of sister chromatids occurs _______. View available hint(s) separation of sister chromatids occurs _______. In mito

mafiozo [28]

The separation of the sister chromatids during the cell division occurs in the anaphase in mitosis and anaphase II in meiosis.

During the anaphase in mitosis, and the anaphase II of the meiosis, the chromosomes aligned at the center of the nucleus separates and the sister chromatids of the chromosomes starts moving towards the opposite poles as the spindle fibers starts contracting.

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

marysya [2.9K]

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).

Why is it important that we understand and are able to use the metric system?

Artyom0805 [142]

The metric system is a system of weights and measures that was first applied in 1795 in France. Experts everywhere the world use it as the international standard to evidently communicate data. The significance are the following:

• SIMPLICITY which is the metric system is much simple than the english system because it uses a standard conversion influence for all units.

• FAMILIARITY which is almost every nation excluding the united states has accepted the metric system as its official system of weight and measures.

• UNIFORMITY which is scientists use the metric system so all experiments are conducted using the same weights and measures.

• HISTORY which is the general session on weights and measures formally chosen six metric units to be used as international standards in 1954 and in 1960 and the meter was formally distinct established on the wavelength of light from krypton atoms.

• TYPES which is the metric system use meters for space, grams for mass, liters for volume and candelas for light.
