1. Introduction to Zoology Flashcards
•It states thar organisms change their behavior as the environment change
•If organisms’ organs are used more frequently, it will develop in their life time
who’s theory of evolution is this?
John Baptise Lamarck
This theory is based on George Cuvier it States that
•He argued that the significant events such as great floods, and the rapid formation of mountain chains have led to killing plant and animals that lived during these periods
• As the fossil records showed some of the inconformities in the strata analysis, there is no
evidence that these events had killed all animals and plants
• There is also no evidence that these events helped in the evolution of animals
Catastrophic Events on the Earth
What Theory is this?
He argued that the giraffe, for example, had a short neck.
It made the nerve fluid to flow into
Theory of Use and Disuse
This property would inherit in its offspring.
This theory is not accurate for two reasons
Firstly, there is no evidence in the fossil records that there were different species
of a giraffe that has a short neck.
Secondly, if we considered this theory, so the offsprings of swimmers will have
long legs or stretched body
Theory of Transition of Acquired Characteristics
True or False
The Theory of natural selection and it is more accurate and reasonable rather than Lamarck’s and Cuvier’s theory?
True
State the four stages that a butterfly go through
Egg Stage
Larva or Caterpillar
Pupa or Chrysalis
Adult Butterfly
_______ is a process in the cell division processes, by splitting the cell nucleus into two nuclei; it divided into several phases
Mitosis
State the five stages of mitosis
Interphase
Prophase
Metaphase
Anaphase
Telophase
_______ is the phase that occurs before the mitosis processes
Interphase
________ starts at the beginning of the mitosis process
Prophase
In the _____ phase the sister pairs of chromatids gather in the center of the cell align along with the metaphase plan.
Metaphase
What phase is the polar microtubules separate the chromatids and push the chromosomes to each pole
Anaphase
And finally in this phase the two cell daughters are formed, and the cell separate to produce two distinct nuclei
Telophase
State the two types of cell
Prokaryotes and Eukaryotes
this is a type of cells that have nucleus and membrane-bound organelles; which help to organize and compartmentalize the functions in the cell
Eukaryotes
