Sensory Receptors
How does your body know how to respond to something happening inside or outside your body?
Through the brain or nervous system.
What are all of the body systems?
Respiratory
Circulatory
Exrectory
Digestive
Nervous
Are all living things made of cells?
Yes
what are the differences in prokaryotic cells and eukaryotic cells
Prokaryotic cells don't have nucleus which eukaryotic cells do
What characteristics do plants and animals have that increase their chances of reproduction?
There color,there smell,there size,there nectar.
How does a sensory receptor work?
Step 1: receive information from the environment
Step 2:Information is carried to the brain
Step 3: Information is processed and a response is selected
Step 4: Response is sent to the correct body system
What are the levels of oragnization(simple to most complex)
1.cells
2.tissue
3.organs
4.organ system
5.organism(human body)
What is the smallest thing that can be considered living?
Cells
what is a Nucleus
Control center of cell
Directs the cell functions
Contains the DNA
Why do organisms have different ways of reproducing?
Because it depends on the organisms features.
How can senses be classified?
They can be classified by the type of input for example,chemical,mechanical,and electromagnetic input
What does the circulatory system do and how does it interacts with other systems?
And what are the organs
Circulatory
Circulates blood through the body carries materials to different locations throughout the body
Heart
Blood vessels
Works with the respiratory system to deliver oxygen to the body
How can we identify things that are living and nonliving?
If they are moving they are living or if they have one or more cells they are living
How is a plant cell different from an animal cell?
A plant cell has a cell wall and chlorplast and an animal cell doesn’t have ethier.
What adaptations do plants or animals have to help them reproduce? and why
Bright colored flowers that attract birds to the pollen which increases the odds or reproduction to find a mate.
What is a stimulus and why is it important for our sensory receptors?
An action or change that creates a response
What are the various functions of the body systems? and what do they do
Excretory filters out waste, circulatory delivers oxygen to the body, breaks down and processes food to be transported, nervous sends and receives signals, muscular herpes move the body and contract muscles, respiratory inhales oxygen and exhales C02
Function of a cell:
reproduction
protection
energy needs
transportation
what is Mithocondria
Site of cellular respiration
Provides energy for the cell to be used by the cell or released elsewhere
Converts the stored chemical energy in glucose into chemical energy in ATP
How do animal behaviors affect the probability of successful reproduction in animals? and List examples of different animal behaviors that contribute to successful reproduction.
Vocalization,dances,actions,showing off something for example a peacocks feathers.
Behavior affects the probability of reproduction by increasing the rate of finding a mate. and some examples are Vocalization,dances,actions,showing off something for example a peacocks feathers.
If someone Knocks at the door what sense do you use and what input do you use.And what are you memory's and immediate reactions to it.
Hearing
Mechanical
Sensory receptors send signal to brain, brain processes signal and determines a response
Memory: Recognize the sound
Immediate Behavior: Go check who is at the door
Why can you not function properly without one of your body systems?
Because all of the body systems rely on each other to function
What are the two types of cells and How do we know if an organism is that kind of cell.
unicellular and multicellular and
Unicellular has one cell and muliticelluar has more than one cell
What is an organelle and what type of cells can they be found in?
An organelle performs a specific function to help meet the basic needs of the cell. They are found in Eukaryotic cells.
What is reproduction and what are the two types of reproduction?
Asexual and sexual. Asexual only uses one parent of reproduction while sexual uses 2 parents,the female containing egg cell and male containing the sprem cell.
