Homeostasis in Cells

THE CELL (or plasma) MEMBRANE!

• The cellular (or plasma) membrane is responsible for controlling substances entering and leaving its boundaries.

• Hypertonic, Isotonic, and Hypotonic situations/solutions

• Balance & Equilibrium

• Water soluble and insoluble substance control

Homeostasis

Keeping "normal" conditions for survival

​

​Proper functioning of systems

​

​Maintaining Equilibrium

Homeostasis

Negative Feedback Loop

​-Nothing bad about this system

​-Simply moves back to a "normal" state

-Ex. If your body temperature rises to 103 degrees (F), and then returns to 98F hours later, that is movement in a "negative" direction...but totally normal!​

Open Ended

What is another example of a "negative feedback mechanism" in your body?

Homeostasis

Positive Feedback Loop

This mechanism results, usually, in a permanent change

​

It also is a push to a "completion" of something. Ex. pregnancy

​

​It's a change in the SAME direction, unlike NF, whereas the change goes back the other way

Multiple Choice

Which of those examples was a POSITIVE feedback loop?

• The pregnant woman

• Cut on arm

• Blood pressure

• Running a fever

Multiple Choice

How do you "win" at natural selection?

• survive

• go extinct

• survive & reproduce

Multiple Choice

What word describes a trait that helps an organism survive in its environment?

• natural selection

• mutation

• camouflage

• adaptation

Multiple Choice

Which organisms are most likely to survive?

• the best adapted
• the fastest
• the strongest
• the most domesticated (tamed)

Multiple Choice

The trees these moths used to live on were white, but have been covered in soot from coal factories. Which moth will be more successful in this environment?

• Dark moth
• Light moth
• Both will be equally successful
• Neither will be successful

Multiple Choice

Why is the mouse population changing over time?

• The light mice can reproduce more successfully than the dark mice
• The hawks eat more dark mice than light mice because the dark mice taste better
• The hawks eat more light mice than dark mice because they can see the light mice more easily
• The hawks eat more dark mice than light mice because they can see the dark mice more easily

Multiple Choice

These moths are all the same species. The differences between their wings is an example of ________________

• Natural Selection
• Variation
• Homeostasis
• Extinction

Multiple Choice

When an organism of a species has an adaptation, it will compete for resources better, survive longer and pass that adaptation on to it's offspring. This process is called

• evolution by natural selection
• artificial selection
• inbreeding
• outbreeding

Multiple Choice

Which of the following explains adaptation.

• An individual organism changes to meet its needs in the environment. These changes pass down to their offspring.
• The species as a whole changes their characteristics.
• Beneficial traits allow organism to survive and pass on those traits
• New characteristics arise in a species as needed.  If these traits are helpful, they are passed down.

Multiple Choice

When an environment changes faster that an species can adapt, the most likely outcome is...

• ...biological evolution.
• ...voluntary mutation
• ...species extinction
• ...selective breeding

Multiple Choice

Evolution works by 

• individuals changing to suit their environment

• Individuals learned new traits and pass them on

• no change in the environment cause a species change 

• small changes passed down through many generations

Multiple Choice

Mutations are important because they bring about

• death of the organism in which they develop
• genetic variation needed for a population to evolve
• benefits for the individual, not for the population
• Hardey-Weinberg equilibrium within a population

Multiple Choice

What is another name for natural selection?

• survival of the smartest
• survival of the fastest
• survival of the biggest
• survival of the fittest

Multiple Choice

Which of the following is a factor in natural selection?

• Individuals of species compete with one another to survive.
• All species are genetically diverse.
• Individuals better able to adapt to changes leave more offspring.
• All are correct 

Multiple Choice

Charles Darwin observed that finches of different species on the Galápagos Islands have many similar physical characteristics, this supports the hypothesis that these finches

• are twins

• acquired traits through use and disuse.

• all eat the same type of food.

• descended from a common ancestor.

Multiple Choice

Cattle egrets forage (feed) in fields among cattle. The egret gets easy access to flying insects stirred up by the cattle, and the cattle don't care if they are there or not.

• mutualism
• commensalism
• competition
• parasitism

Multiple Choice

-

• Predation, because the ants feed on the fungi

• Mutualism, because both the ants and the fungi benefit from each other

• Competition, because both organisms consume the same resource for energy

• Commensalism, because the ants receive energy from the fungi and the fungi are unaffected

Multiple Choice

The acacia ant nests and feeds in the plant’s hollow thorns. The ant helps protect the bullshorn acacia by attacking insects and grazing animals that come near the plant. The relationship between the acacia ant and the bullshorn acacia is an example of which of the following?

• Commensalism

• Mutualism

• Neutralism

• Parasitism

Multiple Choice

a relationship that occurs when two or more organims of the same species need the same resource at the same time

• competition
• symbiosis
• predation

Multiple Select

What are autotrophs

• organisms that produce their own food

• producers

• organisms that consume what they eat

• consumers

Multiple Choice

Where does the energy flow start in an ecosystem?

• autotrophs

• heterotrophs
