Classification of Living Things Notes
1. An organism is a living thing.
2. Characteristics of all living things:
1) Organisms obtain and use resources. All organisms must obtain resources, such as food and water, which provide required energy to perform the basic processes of life, like growing, developing, and repairing injured parts.
2) Organisms respond to stimuli: A stimulus is any change in an organism’s surroundings that will cause the organism to react. Examples of environmental stimuli include changes in the amount of light present, changes in temperature, sound, amount of water, space, amounts of food present. The reaction to the stimulus is called a response. It can be an action or behavior performed by the organism.
3) Organisms reproduce-produce offspring that have similar characteristics as the parents. Reproduction can occur in one of two ways:
a) Asexual reproduction involves one parent that makes an exact copy of itself. The offspring are identical to the parent.
b) Sexual reproduction involves two parents. Sperm cell from the male and egg cell from the female combine to produce offspring that have characteristics from each parent.
4) Organisms grow and develop. Growth is the process of an organism becoming larger. Development is the process that occurs during the life of an organism that results in the organism becoming more complex. Organisms require energy to grow and develop.
3. Classification is the process that scientist use to arrange organisms into groups based on the shared observable characteristics.
4. Taxonomy is the science of identifying and classifying organisms into groups.
5. A taxonomist is a scientist who identifies and names organisms based on their similarities and differences.
6. Taxonomist use physical characteristics as well as DNA, genetic information, to classify organisms.
7. Scientist all over the world study organisms, in order to avoid confusion scientists need a universal way of naming organisms.
8. A dichotomous key is a tool used to identify organisms. It uses a series of questions, each with only 2 answers.
9. Linnaeus developed a system for classifying organisms called binomial nomenclature. It uses two Latin words to name an organism. The name is made up of the genus and species of the organism. The name is written in italics, the genus is capitalized, and the species is lower case; for example, the scientific name for a human is Homo sapiens.
10. The Linnaeus system is made up of seven levels, Kingdom, Phylum, Class, Order, Family, Genus, and Species.
1) King Philip Could Only Find Green Socks is one mnemonic way to remember the order of the levels. Another is King Philip Came Over For Good Spaghetti.
2) The levels are arranged from the most broad, Kingdom, to the most specific, Species.
11. Kingdom- organisms are placed into kingdoms based on their ability to make food and the number of cells in their body.
12. Phylum (phyla is plural)- In the Plant Kingdom, phyla are sometimes called divisions. In the Animal Kingdom, there are 35 different phyla.
13. Class, Order, Family-these levels become even more specific. Each level has fewer organisms that have more in common with each other as you move down the levels.
14. Genus- contains closely related organisms. The genus is the first word in an organism’s scientific name.
15. Species- consists of all the organisms of the same type which are able to breed and produce young of the same kind. The species is the second word in an organism’s scientific name.
16. Most scientists classify organisms into 5 kingdoms: Plants, Animals, Protists, Fungi, and Monera.
1) Plants (Plantae)- the plant kingdom is made up of plants. Plants are autotrophs, they make their own food. Plants are eukaryotes; they are made up of many cells. Plants are divided into 2 groups: vascular and nonvascular.
2) Animals (Animalia)- the animal kingdom is made up of animals. Animals are heterotrophs- they must obtain food by eating it. Animals are eukaryotes. The 35 phyla are divided into two groups: vertebrates and invertebrates.
3) Fungi- the fungi kingdom is made up of molds, yeasts, and mushrooms. Fungi are heterotrophs because they must absorb their food. Yeasts are one celled, while molds and yeasts are eukaryotes. Their cells have a nucleus, a cell wall, and no chlorophyll. Most fungi are decomposers, they break down dead organisms.
4) Protists (Protista)- the protists are made up of organisms that cannot easily fit into the plant, animal, or fungi kingdoms. They are one celled organisms with a nucleus or simple multicelled organisms. Some protists are autotrophs, some are heterotrophs.
5) Monera- the Monera kingdom is made up of bacteria. Their cells do not contain a nucleus. Some bacteria are autotrophs, some are heterotrophs.
Alice wants to find out whether her pet gecko finds its prey based on vision. She thinks that her gecko will more easily see the colored crickets. She follows these steps:
get 10 similar crickets from the pet store
tag 5 of the crickets by putting a tiny dab of bright coloring on their backs
release all 10 crickets into the terrarium with the gecko at the same time
after several hours, record the number of tagged and non-tagged crickets still alive in the terrarium
After several hours, Alice notes that only 4 non-tagged crickets were still alive in the terrarium. No tagged crickets were observed. She concludes that her gecko uses mostly its vision to capture and eat its prey.
What is another possible explanation for these results?
She relays more on her vision than her other senses so you could assume she has good eye sight or something.

Explain how seeds travel. Be sure to give examles to support your explantion psb quic
Answer:
Wind, Water, Animals, and Fire.
Explanation:
Wind moves seeds from one place to another. When the seed gets into the air, it gets pushed by wind to another place. Water moves seeds when seeds fall into water and the water moves the seed downstream, or the water evaporates. Seeds get moved by Animals when, for example, a bird eats seeds then flies to another location, and poops out the seeds. Seeds also get moved by Fire when a forest fire erupts and the seeds fall to the ground after the fire dissipates.

Explanation:
Can a purine pair with a purine?
Answer:
A always pairs with T and C always pairs with G. A and G are purines, meaning that they have two rings, while T and C are pyrimidines, meaning they have one ring. Due to the Watson and Crick model, the width of DNA is constant, meaning that there must be a consistant width in each base pairing. As a result, only a purine can pair with a pyrimidine, giving each base pairing a total of 3 rings.

What are nucleic acids responsible for?
Answer:
The functions of nucleic acids have to do with the storage and expression of genetic information. Deoxyribonucleic acid (DNA) encodes the information the cell needs to make proteins. A related type of nucleic acid, called ribonucleic acid (RNA), comes in different molecular forms that participate in protein synthesis.
Explanation:
Nucleotides are important as they form the building blocks of nucleic acids, such as DNA and RNA. Nucleotides are made up of 3 parts. The first is a distinct nitrogenous base, which is adenine, cytosine, guanine or thymine.

Four of the six kingdoms are compromised of organisms that contain
eukaryotic cells. Which structure in a cell would give you the BEST
evidence that the cell is eukaryotic? *
O Ribosome
O Genetic material
O
Nucleus
O Cell membrane
Answer:
The best evidence that a cell is eukaryotic is the presence of the cell structure called the nucleus.
Explanation:
The most significant difference between eukaryotic and prokaryotic cells is that the former have a nucleus, where they store genetic information in the form of DNA.
The nucleus of eukaryotic cells occupies approximately the center of the cell and is a structure associated with the endomembrane system. Its function is to control cell activity, and its genetic material is duplicated before cell division.
In prokaryotic cells, in the absence of a nucleus, the genetic material is dispersed in the cellular cytoplasm.
Regarding the other options:
Both cell types, eukaryotes and prokaryotes, have ribosomes, genetic material and cell membrane.

Answer:
You have no options for me to choose from, but I'm going to make a wordy response anyway. The answer is stated below:
Explanation:
Cellular respiration uses carbon dioxide and releases oxygen, while photosynthesis uses oxygen and releases carbon dioxide.
Cellular respiration uses carbon dioxide and releases oxygen, while photosynthesis uses oxygen and releases carbon dioxide.
What is photosynthesis?Photosynthesis uses carbon dioxide and releases oxygen and cellular respiration uses oxygen and release carbon dioxide.
Photosynthesis is the process in which green plants prepare their own food in the presence of sunlight and light energy is converted into chemical energy by the process of cellular respiration.
The process of photosynthesis takes place in green plants only due to presence of chlorophyll and materials such as sunlight, water, carbon dioxide is required for the process of photosynthesis.
The equation of photosynthesis is represented below:
6CO2+ 6H2O - C6H12O6 + 6O2
The process of food manufacturing in plant is done through photosynthesis and the plants are known as autotrophs as they are the producers.
In the process of photosynthesis the reactant have 6 carbon dioxide molecules and six water molecules, and light energy converted into chemical energy due to presence of chlorophyll.
Therefore, Cellular respiration uses carbon dioxide and releases oxygen, while photosynthesis uses oxygen and releases carbon dioxide.
