Hormones are chemical molecules produced by glands. vasopressin is a hormone secreted by the cells of the hypothalamus, a part of the brain. the hormone regulates homeostasis through its effect on the kidney cells. which statement is true based on this information? a) all cells in the human body produce the same types of hormones. b) specialized cells allow for different organs to work together to perform a function. c) cells can work together only if they’re located in the same area of the body. d) all cells in the human body have the same structure and function.

B) Specialized cells allow for different organs to work together to perform a function.

Explanation:

Homeostasis is the tendency of the body to restricts a  change in the internal body in order to maintain a stable, constant internal environment with irrespective of the changes occurring in the external environment. Hormones are the chemical substances which are secreted by the endocrine system into the bloodstream. Hormones produce an effect on the specific target organs. Hormones can maintain the homeostasis by affecting the target organs.  

According to above situation, B) Specialized cells allow for different organs to work together to perform a function is the correct option.

B) Specialized cells allow for different organs to work together to perform a function.

Explanation:

According to the information differnet organs (brain and kidney) work together to regulate homeostasis.  the brain produces a hormone (vasopressin) that is necessary in the kidney and both organs working together maintain the homeostasis in the organism

population. population is the number of people or animals in a particular place. an example of population is over eight million people living in new york city.

here is your answer hope i .

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
