VC BSC 1010c Study Guide - Exam 1 Questions With
Complete Solutions
- Describe the 7 characteristics that define life. Give an example
of each.
- What is the most basic unit of life? Correct Answers
1)Cellular organization:(most basic unit of
life):structure/function Ex: Bacteria
2)Order: cells-tissue-organs-organ system
3)Sensitivity: Ex:Venus fly trap
4)Growth, development, and reproduction: Ex:DNA(code for
life)
5)Energy utilization : Ex: cellular metabolism
6)Evolutionary adaptation: survival: peppered moth
7)Homeostasis: regulate themselves: core body temp.
- Differentiate between the 4 diverse kingdoms of Eukarya.
Correct Answers 1) Plantae(cellulose) 2)
Animalia(heterotrophic 3) Fungi (chitin) 4)Protista(autotrophic)
- Discuss the 4 unifying themes to biology Correct Answers
The cell theory- is the theory that all living organisms are made
of cells and that these cells come from other cells(Robert Hooke
developed the first microscope and observed plant tissue.)
DNA- is short for deoxyribonucleic acid, this is built of 4
nucleotide codes =Adenine(A), Thymine(T), Guanine (G),
Cytosine(C), DNA is mostly contained in the nucleus.
, Evolutionary conservation- life first arose 3.5 billion years
ago(unicellular prokaryotic cells), Characteristics of earlier
organisms are preserved and passed on to future generations
Evolutionary change- is that organisms have evolved from the
1st cell into diverse complex multi-cellular organisms.
- Discuss the process of water ionization? Why does this occur?
Correct Answers Individual' water molecules commonly break
apart in a process
This produces hydrogen ions (H+) (simply just a proton) and
hydroxide ions (OH-)
- Explain buffers? Provide an example. Correct Answers the
function of a buffer is to maintain neural PH7
they also act as a reservoir for 'H+' (donating/removing them
from solution as needed)
EX; Regulating blood PH
- How does the structure of fats enable them to hold so much
energy? Correct Answers Because carbon-hydrogen bonds are
considered energy rich, fats store a lot of energy per unit.
- Life is built as a hierarchy
- Detail what makes up the cellular, organismal, and population
levels Correct Answers Cellular level= consist of atoms,
molecules, macromolecules, cell organelles, cells
Organismal= tissues, organs, organ system, organism
