1. what is binomial nomenclature?
2. what is the proper protocol for a scientific name?
3. what is the ultimate source of all energy for living things? explain why.

Explanation:

1. Homeostasis is the ability of an organism or system to maintain a stable internal environment. An example is the regulation of body - temperature in humans. When the body is cold, blood vessels constrict to reduce heat loss, and when hot, blood vessels dilate and sweating occurs to cool down.
2. Reproduction is the biological process by which new individual organisms are produced. It can be asexual (involving a single parent and producing genetically identical offspring) or sexual (involving two parents and genetic variation in offspring).

8.
a. Aristotle (384 - 322 BC): Made early contributions to the classification of living organisms and natural history. He grouped animals based on their physical characteristics and behaviors.
b. Linnaeus (1707 - 1778): Developed the binomial nomenclature system for naming organisms, which is still in use today. He also created a hierarchical system of classification (Kingdom, Phylum, Class, Order, Family, Genus, Species).
c. Whittaker (1920 - 1980): Proposed the five - kingdom classification system (Monera, Protista, Fungi, Plantae, Animalia) in 1969, which was a significant advancement in the classification of life.
d. Hooke (1635 - 1703): He is known for his work in microscopy. He coined the term "cell" after observing cork under a microscope.
e. Van Leeuwenhoek (1632 - 1723): He was a pioneer in microscopy. He was the first to observe and describe single - celled organisms (microorganisms) using his hand - made microscopes.

1. Binomial nomenclature is a formal system of naming species. Each species is given a two - part name: the genus name (capitalized) and the species name (lower - case), both in Latin or Latinized form. For example, the scientific name of a human is Homo sapiens.
2. The proper protocol for a scientific name is that the genus name is capitalized, the species name is lower - case, and the entire name is italicized (when typed) or underlined (when hand - written).
3. The ultimate source of all energy for living things is the sun. Through the process of photosynthesis, plants convert solar energy into chemical energy (glucose). Other organisms then obtain energy by consuming plants or other animals that have consumed plants.

Answer:

1. Homeostasis is the maintenance of a stable internal environment. Example: Body - temperature regulation in humans.
2. Reproduction is the production of new individual organisms, either asexually or sexually.

8.
a. Aristotle (384 - 322 BC): Early organism classification.
b. Linnaeus (1707 - 1778): Binomial nomenclature, hierarchical classification.
c. Whittaker (1920 - 1980): Five - kingdom classification.
d. Hooke (1635 - 1703): Coined "cell", microscopy work.
e. Van Leeuwenhoek (1632 - 1723): First to observe microorganisms.

1. A two - part naming system for species (genus + species, in Latin or Latinized form).
2. Genus capitalized, species lower - case, italicized or underlined.
3. The sun, because of photosynthesis converting solar energy to chemical energy for food chains.
