Which feature of the nucleus is not clearly shown by the visual analogy? please do number four4

or more

Explanation:

4.the chromatin is not shown

5. What is another possible analogy that could be compared with the structure and function  of a cell?

The structure and function of an airport control tower could be compared to the structure and function of a cell

6.Vacuoles are membrane-enclosed saclike structures that store materials such as water, salts, proteins, and carbohydrates.

7.Storage of materials and support of the cell

8.Contractile vacuoles pump excess water out of the cell, while other types of vacuoles hold materials inside of cells

10.Lysosomes breakdown large molecules and waste without them clutter could accumulate in the cell, which has been linked to serious human diseases

11.centrioles

12.cilia

13.Ribosomes are small particles of RNA and protein found throughout the cytoplasm. They are involved in synthesis of proteins.

14. Endoplasmic reticulum

15.Ribosomes are found on the surface of rough ER. Smooth ER has no ribosomes on its surface.

16.The Golgi apparatus is like a customization shop in a factory. It puts the finishing touches on proteins before they leave the factory.

17.If the cell manufactures proteins that are normally released to travel to other cells. Those cells would not receive the proteins. The loss of these proteins might cause the "receiver" cells to function poorly.

19.True

20.Like

21.True

22.Contain

23.walls

24.wood

25.regulates

27.Vesicles transport newly synthesized proteins to the Golgi apparatus. After the Golgi apparatus modifies the proteins, vesicles transport the modified proteins to the cell membrane, where they are released.

b is the correct answer

the african cheetah.

this species has a relatively low level of genetic

variation because the population was reduced to a small size approxi-

mately 10,000 to 12,000 years ago.

until   now,   we   have   primarily   focused   our   attention   on   genes  

within   individuals   and   their   related   family   members.   in   this  

chapter   and   chapters   25   and   26   ,   we   turn   to   the   study   of   genes   in  

a   population   or   species.   the   field   of

population   genetics

  is   con-

cerned   with   changes   in   genetic   variation   within   a   group   of   indi-

viduals   over   time.   population   geneticists   want   to   know   the   extent  

of   genetic   variation   within   populations,   why   it   exists,   and   how   it  

changes   over   the   course   of   many   generations.   the   field   of   popu-

lation   genetics   emerged   as   a   branch   of   genetics   in   the   1920s   and  

1930s.   its   mathematical   foundations   were   developed   by   theoreti-

cians   who   extended   the   principles   of   gregor   mendel   and   charles  

darwin   by   deriving   formulas   to   explain   the   occurrence   of   geno-

types   within   populations.   these   foundations   can   be   largely   attrib-

uted to three scientists: sir ronald fisher, sewall wright, and j. b. s.

haldane.   as   we   will   see,   support   for   their   mathematical   theories  

was provided by several researchers who analyzed the genetic com-

position   of   natural   and   experimental   populations.   more   recently,  

population   geneticists   have   used   techniques   to   probe   genetic  

variation   at   the   molecular   level.   in   addition,   staggering   advances  

in   computer   technology   have   aided   population   geneticists   in   the  

analysis   of   their   genetic   theories   and   data.   in   this   chapter,   we   will  

explore   the   genetic   variation   that   occurs   in   populations   and   con-

sider   the   reasons   why   the   genetic   composition   of   populations   may  

change over the course of several generations
