Science multiple choice questions?

1) Scientists wanted to study the effect of water temperature on the swimming speed of carp. They set up an experiment in which they raised populations of carp in two different aquariums. Population 1 was raised at 8 degrees C. Population 2 was raised at 27 degrees C. All other variables were constant in both aquariums.

If the temperature of the water increases from 8 degrees C to 15 degreesC, the carp in Population 1 would most likely

Choose one answer.

a. eat less food.
b. excrete more salt.
c. use more oxygen.
d. produce less carbon dioxide

2) The breathing rate of a goldfish can be measured by the number of times the goldfish opens its mouth. In an experiment, students placed a goldfish in a container of water at 26 degrees C and counted the number of times the fish opened its mouth. They gradually lowered the water temperature and counted the number of times the fish opened its mouth at 20 degrees C, 14 degrees C, 8 degrees C, and 2 degrees C.

Which of these descriptions best explains the decrease in the breathing rate of the goldfish?

Choose one answer.

a. The rate of metabolic activity decreased.
b. The fish’s activity levels increased.
c. The demand for carbon dioxide decreased.
d. The demand for oxygen increased.

3) Overfishing of large predatory fish has left a stream free of many predators. This will result in the stream ecosystem having a…

(remember the boom and bust cycle from ecology?)

Choose one answer.

a. other plants will produce enough food for herbivores
b. an animal species will fill the unoccupied niche

5) The biome with the greatest number of species would also have the greatest variation in

Choose one answer.

a. habitats
b. animal life
c. consumers
d. plant life

6) A certain type of animal has long shaggy dark-colored fur, short legs, and a compact, chunky body. This animal has powerful hind legs and hooves with a hard outer trim and a rubbery inner surface.

Which of these biomes is most likely to be the habitat of this animal?

Choose one answer.

a. Hot, little precipitation, gravelly soil, scarce canopy
b. Cold conditions (below 0ºC at night), low biotic diversity, well-drained soil, ground-hugging vegetation
c. Varied temperatures (-30º to 30º C), even precipitation throughout year, moderately dense canopy, rich soil
d. Moist and humid, plants grow in standing water, thick canopy and groundcover, highest ecosystem diversity

7) An environment has cold winters with temperatures often below freezing and hot summers with temperatures often above 75 degrees F. It receives a moderate amount of rain and snow each year. Which of these organisms would most likely live in this environment?

Choose one answer.

a. maple tree – temperate deciduous forest biome
b. palm tree – tropical forest biome
c. olive tree – chaparral biome
d. cactus – desert biome

New Niche Finder answers:

1. C. Goldfish are ectotherms, whose internal body temperature, metabolic rate (and, presumably, level of activity) varies with the environmental temperature. When the water at 8o C is increased to 15o C, the temperature of the fish, and thus its metabolic rate would increase. With increased metabolic rate, more oxygen is consumed, and more carbon dioxide is produced. It might eat more food over a longer time scale, but its excretion of salt would not change. Actually, it probably doesn’t excrete salt at all, in either temperature – it lives in fresh water and would be much more likely to retain the salt.

2. A. As the water temperature decreased, the internal body temperature and the metabolic rate of the fish would decrease. The activity level and demand for oxygen would also decrease. There is no demand for carbon dioxide; it is a waste product.

3. D. Increase in prey fish. If there are fewer predators, fewer prey would be caught. There would be no direct effect on pollutants either way, and aquatic plants (assuming the prey fish ate them) might actually decrease.

4. Most likely d. A food “web” implies that there are several species in each trophic level. If a dependent herbivore cannot find a substitute, it will die, but if it can eat other plants, there would probably be enough (answer a) to feed it as well. An animal species cannot replace a photosynthetic plant, but a carnivore might be affected by the change, if its prey ate the missing plant and thus decrease in numbers.

5. Again, most likely answer is a. Habitats. B and c (animal life and consumers) are the same; plant life is too limited. More species mean more niches for those organisms (both plants and animals) to inhabit.

6. Probably b. The compact chunky body, shaggy fur and short limbs imply an animal that lives in a cold environment because it it better at retaining heat, which eliminates answer a. The hooves make the swampy conditions in answer d unlikely. Both b and c are possible, but b is more likely because of the adaptations to a cold environment.

7. A. Maple tree – temperate deciduous forest. It’s not b because of the cold winters, and is not b, and is unlikely to be c because of the moderate rain and snow.

Richard asks…

Question about global warming & ‘An Inconvenient Truth’?

Please help me answer these questions. These questions had to be answered after watching the movie ‘An Inconvenient Truth’. I have done a lot of research but I could not find the answers to these questions. Please do try to answer all the questions (even if you’re not sure) but if even if you can answer a few, it would be greatly appreciated.

1. Who was the first person to propose measuring CO2 levels in the atmosphere?

2. Why do CO2 levels in the atmosphere have such drastic fluctuations within a year?

3. What trends can be seen in CO2 levels from 1958 – 2005?

4. How are scientist able to determine temperature and CO2 levels from specific years so long ago?

5. How recently did the 10 hottest years ever recorded occur?

6. Why did Katrina change from a category 1 hurricane before reaching New Orleans?

7. The ocean currents are interconnected via a conveyor type system. What would happen to this system if Greenland had to melt and why?

8.Describe 3 ecological niches that are affected by global warming?

Thank you so much :)

New Niche Finder answers:

1. John Tyndall discovered the greenhouse effect in 1861 and Svante Arrhenius did some more tests to improve our understanding of CO2’s role in it in 1896.

Tyndall – http://onramp.nsdl.org/eserv/onramp:16571/n3.Tyndall_1861corrected.pdf
Arrhenius – http://new.globalwarmingart.com/images/1/18/Arrhenius.pdf

2. I believe this is based on the seasons and oceanic and plant based uptake of CO2

3. Trends have been positive

Scripps CO2 Program – http://scrippsco2.ucsd.edu/

4. Atmospheric CO2 has been measured since 1958 and there are various techniques for CO2 measurements of the past including air bubbles in ice cores.

Scripps Mauna Loa Data – http://scrippsco2.ucsd.edu/data/in_situ_co2/monthly_mlo.csv
Ice cores – http://cdiac.ornl.gov/trends/co2/lawdome.html

5. The 10 warmest years recorded since measurements began have all occurred within the past 12 or 13 years.

GISTemp Data – http://data.giss.nasa.gov/gistemp/graphs/Fig.A2.gif
HadCRUT Data – http://www.cru.uea.ac.uk/cru/data/temperature/nhshgl.gif

6. Hurricanes or Cyclones gain strength from sea surface temperatures. The warmer SSTs are the more powerful a hurricane will be. However there are other variables that can affect hurricanes frequency as well.

Http://www.geo.utexas.edu/courses/387h/PAPERS/Webster,P.J.-Science2005.pdf

7. The system would shut down due to decreased salinity

“Given the role that salinity plays in maintaining the oceanic conveyor belt, a decrease in salinity due to the addition of fresh water (which is less dense) threatens to slow or shut down the Oceanic Conveyor Belt. If the conveyor shuts down, it will no longer bring warm ocean waters from the south to areas of Northern Europe. Since the ocean plays an important role in the local climate balance, this could lead to a dramatic drop in local temperatures for Northern Europe.”

Lisa asks…

Is it too late for me to start riding English!?

I have been riding western forever but I have always always admired and wanted to try English. Oddly enough, I do have an English saddle because that’s what I used to ride one of my horses in because he could do either. But I had to put him down last Monday and it tore me up. I finally feel like I need to start riding again and I need to stop sitting on my ass and make something of myself. I’m 16 but I am motivated and loyal and I have dedication uncommon in someone my age. I have never brushed off any advice given to me when it comes to horses and I take constructive criticism well. But, to me it almost doesn’t feel acceptable for someone my age to start this late in the game. Is that ridiculous? Is it ok for someone my age to begin a new discipline?I’m not lacking in western experience. I can handle problem horses well, a few of which I’ve molded into wonderful children’s horses. I guess what I’m trying to day is that I dont want to be looked down upon. Also, I have a 5 year old quarter horse mare named Freckles and Fudge by Hot Fudge Chip who is bred out the ass!! She has near perfect conformation and she is soo smart! She has been trained in western pleasure until I got her about 5 months ago. She isn’t finished but she works entirely off leg pressure, half passes, turns on haunches, and lopes. But she’s a little too fast for WP. I think she would be excellent in reining. She is honestly exploding in talent! So, should I cater towards Freckle’s natural talent or do I go outside my comfort zone and pursue English? I’m looking for opinions so please please help me out! I’m ready to be serious about my riding. I’m taking freckles to college and we need to find our niche! Thanks!!

**I’m not inexperienced, I know what I’m doing around horses, I’ve been around them for a long long time. I have 5 of my own and I get sent troubled horses often. I just have a lot of unused talent. So please don’t talk to me like I’m a novice. Thank you.

New Niche Finder answers:

It’s never too late to try something new. There are plenty of teenage and adult beginners, which you aren’t. You’re already an experienced rider, so learning to ride a different discipline won’t take you long at all. You won’t have any issues riding or controlling a horse just because you’re in a different saddle (if you do, you weren’t that experienced to begin with). Your position will vary slightly, but that’s a matter of finesse that comes with time and practice and teaching your body a different way of riding. The differences between western and English are very easy to adapt to and learn if you already know how to balance and control the horse.

If your mare is too forward for WP, she might do great in English. I have a gelding who was bred and trained for WP, but the first year or two I had him, he had trouble staying super slow for WP, so I did mostly HUS and he did great. Now he’s developed enough body strength to hold the slow pace, so we do a lot of WP, too, but he’s learned how to change back and forth and we do both (successfully). There’s no reason you can’t or shouldn’t try your mare in English. If she likes it and does well, great. If she’s not the best, that’s okay–you can either keep doing it for fun (and keep working with her to improve) or you can switch to something else. And if your mare is still green and young, don’t give up on the WP if that’s what you like. It took my horse a good 2-3 years to really figure out the WP, long after he was showing successfully in everything else. If I had kept him in full training, it might have been faster, but I did most of it on my own. It’s very possible your mare will figure it out. Speed (or the lack thereof) is generally the last thing they figure out…it’s better for your mare to move correctly and be a little faster now, and then slow down later, than to force her to be slow and lose everything else.

I actually know a couple of reining horses who were ridden English fairly well. Both were owned by the same woman. One was a great kid’s horse, so a local kid borrowed him for some shows one year and wanted to do everything, not just reining. She showed him in the English and he did a great job and was a really cute mover, and he still did well in the reining. The other horse was a reining/cow horse, but she would occasionally stick English tack on him and use him to fill the HUS/Eq classes if necessary (more people equaled more points). He wasn’t the prettiest English mover, but he was perfectly capable of walk/trot/canter around a ring.
