Cell Signaling
If a hormone is inhibited, what happens to the level of hormone?
Decreases or halts (Depending on the situation)
Which portion of the cell cycle takes the longest
Interphase (G1, S and G2)
Which portion of the Cell cycle takes the least amount of time?
Mitosis (Interphase takes up most of the time in which the cell is growing and performing its role)
Mr. Ayala Has 20 Apples. He eats 1 apple. How much percent of apples remain when compared to the initial amount f apples?
95%
If a hormone releases, what happens to the level of hormone?
What phase will a Cell go into when it is deemed unfit for reproduction? and what happens to the cell?
G0, either killed or allowed to live its life without reproducing
Chromosomes begin to condense from chromatin; spindle apparatus assembled.
Prophase
Uncontrolled cell proliferation
Cancer
In reference to osmolarity, what goal does your body have if salt concentration or water concentration gets too high or too low in your bloodstream?
Maintain equilibrium. This can be done as your body communicates with itself to adjust as needed.
Chromosomes are duplicated during this phase, 2 sets of DNA will exist in the cell until the end of M phase (Mitosis)
S Phase
Chromosomes reach maximum condensation and align on metaphase plate/plane.
Metaphase
If a cell mutates and it will affect the cell in a negative way, a signal can be given to the cell to self terminate, what is this called?
Apoptosis
An error in a cell signaling pathway can result in what?
Disruption of the pathway, inhibition or uncontrolled release of a hormone, cancer
List the steps of the Cell Cycle in order
Interphase (G1, S, G2), Prophase, Metaphase, Anaphase, Telophase, Cytokinesis
Two-chromatid chromosomes split into two daughter (one-chromatid) chromosomes; chromosomes move to opposite poles of the spindle apparatus.
Anaphase
A pair of homologous chromosomes has failed to separate or segregate at anaphase so that both chromosomes of the pair pass to the same daughter cell
Nondisjunction (Aneuploidy can also work -a genetic disorder in which the total number of chromosomes does not equal 46)
This portion of the brain controls your autonomic body systems by controlling your bodily hormones.
Hypothalamus
This blocks cell cycle progress unless specific molecular and/or physical conditions are satisfied
Checkpoints
2 answers- 1. Chromosomes disperse back to chromatin form, nuclear envelope reassembles, nucleoli reassemble. 2. Cell pinches and divides
Telophase and Cytokinesis
What is Mr. Ayala's Favorite Pokemon?
