Answer:
The answer is Spanish flu
Answer:
H1N1 virus with genes of avian origin
Explanation:
The outbreak was caused by an influenza type, where the subtype of it is know as H1N1 virus.(. Characterization of five of the eight RNA segments of the 1918 influenza virus indicates that it was the common ancestor of both subsequent human and swine H1N1 lineages, and experiments testing models of virulence using reverse genetics approaches with 1918 influenza genes have begun in hopes of identifying genetic features that confer virulence in humans.....

Answer:
When an animal breathes, it takes in oxygen gas and releases carbon dioxide gas into the atmosphere. This carbon dioxide is a waste product produced by the animal's cells during cellular respiration. Cellular respiration occurs in the individual cells. Digested foods have chemical energy stored in them.

Organisms of either extreme characteristic dying out while organisms with the medium characteristic have a higher fitness is identified as?
Answer: Stabilization selection
Explanation:
Natural selection involves the differential survival and growth of organisms which have suitable traits to survive in unfavorable or adverse environment. Such traits are passed on to the next generation. Stabilization selection is a type of natural selection in which the nature selects the non-extreme phenotypic traits. Middle traits are selected and such organisms grow and reproduce. Example can be given that of human babies in which babies with low weight lose more heat and babies with high weight are difficult to be delivered from the pelvis. Therefore, babies with middle weight are expected to survive more than that of low or middle weight.
what is the meaning of
•molecule
•compound
•atom
•element
•organic compound
•inorganic compound
Molecule: a molecule is the smallest particle in a chemical element or compound that has the chemical properties of that element or compound. Molecules are made up of two or more atoms that are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons among said atoms. Although oxygen is an element, it naturally has 2 atoms (O2), because it is a halogen and in order to reach 8 valence electrons and become stable and unreactive, it bonds with another oxygen atom. This means that oxygen atoms and oxygen molecules are different; one is an element, the other is a molecule.
Pure Substance: can be divided into two sub-categories: compounds and elements.
Compound: A chemical compound is a chemical substance composed of many identical molecules composed of atoms from more than one element held together by chemical bonds. A molecule consisting of atoms of only one element is therefore not a compound, meaning that oxygen molecules (O2) are NOT compounds. NaCl, or table salt, is.
Atom: An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms.
Element: An element is a pure substance consisting only of atoms that all have the same numbers of protons in their atomic nuclei. Elements are the base, more "pure" of the pure substances. Each element is assigned a symbol. Perhaps the most recognizable of them is H, for hydrogen.
Organic Compounds: organic compounds are generally any chemical compounds that contain carbon-hydrogen bonds. The study of these is called organic chemistry. I mean, carbon is the basis of ALL known life.
Inorganic Compounds: They are any substance in which two or more chemical elements (usually other than carbon) are combined, nearly always in definite proportions. Compounds of carbon are classified as organic when carbon is bound to hydrogen. THE OPPOSITE OF ORGANIC COMPOUNDS.

in your own words, write the definition for Chitin. (include what organisms have chitin and what purpose it serves)
Answer:
Chitin is a structural polysaccharide made up of modified glucose chains. Insect exoskeletons, fungus cell walls, and some hard structures in invertebrates and fish all include chitin. Chitin is an important biopolymer found in nature. Fungi, arthropods, and nematodes are the principal producers. In insects, it acts as a scaffold, supporting the epidermis and trachea cuticles, as well as the peritrophic matrices that line the gut epithelium.

The series of diagrams below represents a process carried out by a unicellular organism. This process is know as
Phagocytosis is a crucial mechanism by which cells engulf and absorb foreign substances. This method is how small, unicellular organisms like free-living amoebas obtain food. Thus, option B is correct.
What phagocytosis process carries by unicellular organism?Phagocytes, a type of living cell, devour or engulf other cells or particles through a process known as phagocytosis. An amoeba or other free-living single cell could make up the phagocyte, or it could be one of the body's cells, like a white blood cell.
In unicellular creatures, phagocytosis is a critical mechanism for nourishment; in multicellular organisms, it is a function of specialized cells called phagocytes.
Therefore, Phagocytosis is a process used by some single-celled protists, such as amoebae, to absorb food particles.
