Criteria for life
The first criterion of life is that all living things contain hereditary information in their DNA that enables life to continue through _______________
Reproduction
DNA is an __________ manual with information to make materials for a living thing.
instruction
In just a few days, a single army ant queen can lay up to 300,000 eggs. With this information, would you expect that ants live a safe life or a dangerous life?
Organisms that have lots of offsprings most often live dangerous lives. This ensures a greater possibility that at least a few of them will survive to adulthood in order to reproduce.
The smallest unit of life in creation
cell
Fill in the missing words in the classification division of living organisms:
______, Phylum, ______, Order, Family, Genus, ______.
Kingdom, Class, Species
King Philip's Class Ordered Frozen Grape Sodas
The 2nd criterion of life is that all living things have a method by which they extract __________ from their surroundings and convert it into energy that sustains them.
energy from the glucose
Human DNA is _ _. _% identical from person to person.
99.9%
Yeast is a __________ because it is a type of fungus, breaking down dead organisms into chemical nutrients.
decomposer
bacterial cell
Which is the broader taxonomic grouping: class or order?
class
Kingdom, Phylum, Class, Order, Family, Genus, Species.
The 4th criterion for life is all living things are made up of _____________.
cells
The double helix of the DNA is formed by 2 long strands of atom, alternating between a _______ group and a phosphate group.
sugar
The process by which green plants and some other organisms use the energy of sunlight and simple chemicals to produce their own food.
photosynthesis
A scientist is looking at a slide of microorganisms and identifies a living cell that has no nucleus or other distinct, membrane-bound (protected) organelles. Is it a prokaryotic or a eukaryotic cell?
In the 3-domain system of classification, it is the only domain that has kingdom to further divide it. Is it: Domain Archaea, Domain Bacteria, Domain Eukarya
Domain Eukarya
Domains Archaea and Bacteria are made up of organisms with prokaryotic cells. Domain Eukarya includes organisms that are made up of eukaryotic cells. There are many organisms with these cells, so Domain Eukarya is divided into 4 kingdoms.
The 3rd criterion of life is that all living things can s_______ their surroundings and ____________ to those change.
sense, respond
The information necessary to build and control the molecules of living organisms is stored in a coded series of these 4 nucleotide bases in DNA.
Thymine, cytosine, adenine, guanine
All humans have a hypothalamus, which is a region in the ___________, that signals your body to sweat to cool down, makes adjustment to your breathing rate and the level of sugar in your body.
brain
The main feature of a prokaryotic cell is the ______ visible throughout the cell.
DNA
Fungi and mushrooms are in this domain. It's the only domain that contains organisms that are NOT bacteria.
Domain Eukarya
The 5th criterion of life is that all living things chemically regulate their internal environment so it is _____________.
stable
A scientist analyzes 1/2 of a portion of DNA. She determines the following nucleotide sequence:
adenine, thymine, cytosine, adenine, guanine. What is the nucleotide bases on the other half of this portion of the DNA?
thymine, adenine, guanine, thymine, cytosine
Once a multicellular organism stops growing in size (such as when a child becomes a full grown adult), the cells of the body continue to grow and multiply to replace ________ older cell.
dying
Suppose a scientist is looking at cells from the following organisms under a microscope: bacteria, lettuce, cat, flower, and duck. Which cells would look very similar to each under the microscope?
The flower and lettuce cells would look similar because they are both plant cells. The cat and duck would look similar because they are both animal cells. Bacteria would not look like any of the others because it doesn't have a nucleus and protected organelles.
Which of these domains contains bacteria that can live at the highest altitudes:
Domain Archaea, Domain Bacteria, Domain Eukarya
Domain Archaea contains organisms with prokaryotic cells (bacteria) that are able to survive the harshest environments.
