2. Why they effect humans - Melting glaciers add to rising sea levels, which in turn increases coastal erosion and elevates storm surge as warming air and ocean temperatures create more frequent and intense coastal storms like hurricanes and typhoons.

2. Why they effect the ecosystems - Continual melt from glaciers contributes water to the ecosystem throughout dry months, creating perennial stream habitat and a water source for plants and animals. The cold runoff from glaciers also affects downstream water temperatures.

Answers

Answer:

This question is incomplete as it does not contain any provided information. The information is as follows:

Number of cells: Unicellular

Cell type: Prokaryotic

Location found: Underwater volcano

The answer is Archaea

Explanation:

Living organisms has been classified into a large group of three called DOMAIN consisting of Bacteria, Eukarya and Archaea. The major basis of this classification is the possession or not of a membrane-bound nucleus.

Domains Bacteria and Archaea do not possess a membrane-bound nucleus and hence, are PROKARYOTIC. However, in addition to being prokaryotic, Domain Archaea members are unicellular (single-celled) and are found in locations with harsh environmental conditions e.g volcano.

Therefore, an organism with a PROKARYOTIC cell type, UNICELLULAR number of cells and found in an UNDERWATER VOLCANO will belong to the domain ARCHAEA.

And please put an answer that makes sense
Thank you
Btw it’s science

Answers

Answer:

Binomial nomenclature is basically the scientific classification of organisms, or taxonomy, using a latin name. It uses the genus and the species. For instance, the bacteria Staphylococcus aureus uses binomial nomenclature because Staphylococcus is the genus, while aureus is the species.

Biology Dictionary states, "The genus name is also called the generic name and always begins with a capital letter. For example, binomial name for cats is Felis catus. The genus name must be unique within each kingdom (see image below) but the same genus can be used in more than one kingdom. [. . .] The species within the genus is known by other names depending on the discipline. For general usage, the species is also called the specific descriptor. In botany, it is called the specific epithet and specific name in used in zoology. A species name can be used more than once within a kingdom.The species name always begins with a lower case letter. It can be a noun or an adjective and it must agree with the Latin gender of the genus name; masculine, feminine or neuter. For example, if the gender of the genus is masculine, the species name should end in -us, -a or -um. An example of this is Passer domesticus, the house sparrow, in which Passer has a masculine gender. Endings for feminine species names include -is and -e and -or is used for neuter genders."

how does carbon from the carbon cycle leave the ecosystem?

Answers


Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned.

18. The structural diagram demonstrates two joined amino acids.


Which arrow points to the peptide bond?
A.3
B.1
C.4
D.2

Answers

Answer:D

Explanation:

The structural diagram demonstrates two joined amino acids, and the arrow points 2 to the peptide bond, which is in option D, as a peptide bond is a type of covalent chemical bond that is formed between two amino acids when the carboxyl group of one amino acid reacts with the amino group of the other amino acid.

What is a peptide bond?

The resulting bond that is formed between the two amino acids is called a peptide bond, and the resulting molecule is called a dipeptide. As more amino acids are added to the chain, a polypeptide is formed. The peptide bond is a strong covalent bond that holds the amino acids together in the polypeptide chain. It is important for determining the structure and function of proteins.

Hence, the structural diagram demonstrates two joined amino acids, and the arrow points 2 to the peptide bond, which is in option D, as a peptide bond is a type of covalent chemical bond that is formed between two amino acids when the carboxyl group of one amino acid reacts with the amino group of the other amino acid.

Which phrase best defines a prototype?
the final product, which has undergone extensive testing and redesign
a model that has been redesigned and retested several times
the criteria established to help solve a problem
O a model from which later versions are developed

Answers

Answer:

A model from which later versions are developed.

Explanation:

A prototype is the rough draft of something in a sense, it is not yet complete and is often only the most basic idea to be expanded on in later versions.

The best definition for a prototype is a model from which later versions are developed. Therefore option D is correct.

A prototype is an early or preliminary version of a product, system, or design that is created to test and evaluate its functionality, features, and feasibility. It serves as a proof of concept and helps in identifying any flaws or areas that require improvement before the final product is developed.

The final product, which has undergone extensive testing and redesign, does not accurately define a prototype because a prototype is not the final product but rather an initial version created for testing and refinement.

Therefore, the most accurate definition, emphasizes that a prototype is a model or early version of a product or system that serves as a foundation for the development of subsequent versions based on testing and feedback.
