WARM UP QUESTIONS

Biology BMrs. Rhodes Spring 2014These are completed on a blue page, due each week

Week of March 17 March

17Still taking 2nd trimester EXAMS

18 Define energy. List several types and give several examples

Energy is the ability to do work. Movement is required to be work. Types = solar, mechanical, electrical, nuclear, chemical bonds, etc

Examples = eating food, photosynthesis, charging ipad

19 What is an invasive species? How does this have any relationship to energy?

Species that ‘invades’ an area and outcompetes the native species normally found there.

It disrupts the food web by taking away resources like food or sunlight

20 Define energy transfer and give at least 3 examples.

The energy is moving somewhere else but is also changing form.

Coal (chemical) – power plant – wires (electrical) – transformer – socket – iPad (sound, light).

Sun – wheat – carbs – granola bar – ATP – muscle movement

21 Write the equation for photosynthesis. sunlight

6 CO2 + 6 H2O C6H12O6 + 6 O2

chlorophyll

Week of March 24 I will have a sub on Tuesday and Wednesday to write School Improvement Report

March

24

List 5 carbohydrates and explain where in the carb the energy actually is found.

Glucose, sucrose, fructose, cellulose, starch, sugar, pasta, cookies, bagels, etc

Energy is in the C-C and C- H bonds.

25 What is the role of the circulatory (cardiovascular) system?

What do the words cardio, circulate and vascular mean?

To circulate (move) things. Things like sugar, oxygen, etc. , not to move the blood but to transport the things in the blood.

Cardio = heart, circulate = move in a circle or loop, vascular = tubes or vessels (blood vessels)

26 What things are absorbed by the digestive system?

Sugars, amino acids, proteins, fats, fatty acids, etc.

27 Make a carbon cycle diagram and label the following parts; photosynthesis, cellular respiration and digestion and circulation

CO2 – plant - photosynthesis – sugar – digestion to circulation to cellular respiration – CO2

28 What is/are the energy transfers that occur in photosynthesis?

Solar energy (light and heat; only need light) to chemical energy in carbs. (see Monday )

Week of March 31

March

31How is aerobic cellular respiration (CR) related to organismal respiration (gill/lungs/etc)?

CR needs oxygen, in the

mitochondria In order to

work – breathing provides cells

with that oxygen.

April

1Sketch an ATP molecule.

Note the P-P bonds called “high energy bonds”

Chpt 3 –

P-P is highly AVAILABLE energy.

Sun – lots; hard to store, sugar – stored energy hard to spend, ATP easy to spend format in cells

2 What is a ‘carbon sink’? Traps or holds carbon; reservoir; out of the cycle for a while – carbon in trees – may be trapped there for 100s of years.

3 Why does MI have higher CO2 levels in the winter?

No leaves – no photosynthesis consuming CO2/ plants respiring to stay alive actually give off CO2 – reverses in summer

4 No School ~ Spring Break Starts

Remember you have an extra credit opportunity over break.

Week of April 14 ~ Welcome Back !

April

14

Define ecosystem and give 3-4 examples A defined region and all the living things in the area and all the living things they interact with and all the nonliving things they interact with.

15 Define ecological succession Living things give and take from environment. This changes the environment over time – making it better or worse for specific species – some species are replaced by others.. Field, fills with weeds, then shrubs and small trees, eventually becomes a forest.

16 Describe the 10% rule 10 of energy at each trophic level is available to be used by next trophic level

17 “where does the other 90% go? “ Its lost to environment or stored in organism

18 What is a keystone species? Vital to so many food chains within a food web that it supports the whole web.

Week of April 21 - 25April 21 Define population and give

several examplesAll the individuals of the same species in the same place at the same time that could potentially produce viable offspring.

April 22 How does the predator-prey relationship impact predators? How does it impact prey?

Predator – gets food; if lots of prey its easy, if less prey its harder/ more competition. If lots of predators its harder – less predators = easier

Prey gets better because the best/ fastest/ healtiest/smartest survive – less prey = less competition for resources

April 23 Sketch a graph that shows exponential population growth and give an example of a population that would fit this trend.

Bacteria

rabbits

? Humans fit this trend

April 24 ½ day for conferences

Conferences at HS are 1- 4 and 5-8 pm

April 25 Explain three factors that can cause a population to

decresase/ increase in size

POWER OUT(enough food/ lack of food, more/ less predators, more/ less space – increased competition, disease out break, etc)

Week of April 28 – May 2 This week was notebook paper due to broken printer

April

28

Define biome and give at least 3 examples

Large geographic region

Similar climate (same latitude, temp range and precip amounts, seasons, etc)

Similar vegetation supported because of simiilar climate

Ex: desert, tropical rain forest, temperate grassland (prairie), etc

29 Define terrestrial.

What does the root ‘terra’ mean?

What are some other words with terra in them?

Land or Earth

Land or earth

Territory – region of land, Terrain – like terrain park, Terra Firma, ATV; all terrain vehicle – goes on all kinds of land….

Terrace/ terraced ,Terrarium, extra-terrestrial (beyond earth), terra nova (new land), Mediterranean

30 Define aquatic. Describe at least 4 aquatic biomes.

Related to water – think “agua”

Rivers and streams

Lakes

Ocean – lots of regions’; coral reef, tidal zone, open ocean, abyss

estuary

May 1 Compare and contrast a temperate deciduous forest with a tropical rain forest

Both mostly trees

Both enough rain/precip.

Tropical RF – near equator, lots of rain, wet/dry season, hot

Temp. DF – between equator and poles, some rain, 4 seasons, not always hot, leaves fall off trees

May 2 Define niche An organisms ROLE or FUNCTION in its ecosystem. NOT where it lives (that is habitat)

Does it pollinate, disperse seeds, is it a predator, producer, etc.

Week of May 5 – 9 Return to blue forms…note that puzzle is related to Cinco de Mayo

May 5 List 4-5 natural disasters that impact biomes. Describe the impact of 1 in detail.

Fire, hurricane, snow storm, tornado, drought.

Drought means not enough water may change depth or shape of pond, may mean less things like algae and frogs in food web, could mean less water for deer to drink – looking for new water might put them in the road more….

May 6 Write the equation for photosynthesis and tell the importance of light

Light provides the energy for the reaction.

More light – more photo = more food, more plant growth and more O2…. Tropical rain forest.

Less light – less photo = less plant growth , less food and less O2…. tundra

May 7 No warm up question today X

May 8 How did you prepare for today’s test?

Did you try any new methods of studying? What items did you actually use to study?

TEST !!

May 9 Define heredity and genetics.

What is the difference? How are they related?

•Mrs Rhodes will have a sub to attend her daughter’s college orientation/registration day at GVSU *•Heredity means what you inherit – traits like eye color, ancient idea since we started cultivating crops and livestock•Genetics means studying how the genes store and carry the information about those traits… decoding DNA, newer

Week of May 12 – 16 Start of Genetics UnitMay 12 Describe DNA Deoxyribo Nucleic Acid

Chemical used to store and transfer genetic information. What chromosomes are made of.

One of 4 organic macromolecules (proteins, lipids, carbohydrates and NUCLEIC ACIDS)

The other form is RNA

May 13 Why do cells complete the process of mitosis?

The need to copy all the DNA, then sort and organize it so that when the cell divides into 2 cells they each get a full set of the original DNA

May 14 Why would some cells need the process of meiosis (aka reduction division) instead of mitosis?

Cells that will be used for reproduction only need ½ the DNA ; one of each chromosome vs pairs of each chromosome. This is so each parent can contribute ½ the DNA (one of each chromosome) and the new organism will have a full set of DNA with pairs of each chromosome

May 15 Sketch an animal cell and label the structures used during cell division.

Centrosome chromosome * ½ the words in this unit

Centriole chromatids start with C – make sure

Centromere spindle/ spindle fibers you can tell them apart

May 16 Describe the cell wall (cell plate) found in plant cells.

Plants have a cell wall made of cellulose ( starchy/ firm/ crispy/ wood!) so they can not “pinch the membrane in half” to divide – must construct a cell plate across middle ….
