Answer: Alveoli

Explanation: Alveoli of lungs are surrounded by extensive blood capillaries. The partial pressure of oxygen in the alveoli is higher than the blood entering the pulmonary capillaries, hence oxygen moves into the blood. Carbon dioxide in the lungs simultaneously diffuse out of the blood into the alveolar space.

What is the correct order for the hierarchy of biological organization from the least to the most complex? (concept 1.1)?

hjlf

Answer;

Molecule, organelle, cell, tissue, organ, organ system, organism, population, community, ecosystem.

Explanation;

-The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.

-Organisms are highly organized, coordinated structures that consist of one or more cells. Even very simple, single-celled organisms are remarkably complex: inside each cell, atoms make up molecules; these in turn make up cell organelles and other cellular inclusions.

-In multicellular organisms, similar cells form tissues. Tissues, in turn, collaborate to create organs (body structures with a distinct function). Organs work together to form organ systems.

What is true about elements and compounds elements contain two or more compounds conpounds contain two or more elements compound

statuscvo [17]

Answer:

Taking into account the concepts presented in chemistry with respect to elements and compounds, it is possible to affirm that the compounds are formed by two or more elements.

Explanation:

Two or more chemical elements have the ability to bind -by forming bonds- to obtain a compound. This occurs randomly in nature.

The bonds between the elements that form a compound must be stable enough to ensure the stability of the molecule. A chemical compound can only be separated into the elements that form it by chemical processes.

The bonds types that form compounds can be:

Ionic bond.
Covalent bond.
Coordinated covalent bond.
Metallic bond.

It is necessary to mention that chemical elements are called atoms, and the bonds between them are molecules. The physical and chemical properties of a compound will be different from the properties of the elements that form it.
