Biology 1108 UGA Exam 1 – PUCKO
Questions with Correct Answers 2025
Species CORRECT ANSWER
A group of similar organisms that can breed and produce fertile offspring.
Population CORRECT ANSWER all of the individuals of a single species that interact
Community CORRECT ANSWER
all of the populations of living things that interact in a place
Ecosystem CORRECT ANSWER
a biological community of interacting organisms and their physical environment (living and
non-living variables)
Climate, geology, disturbance CORRECT ANSWER
3 examples of abiotic features of an ecosystem
There is more diversity towards the poles, so as we ascend a mountain, we experience eco
systems that change as a result of levitation CORRECT ANSWER
Why do mountains have increased diverse ecosystems?
Old growth forest CORRECT ANSWER
complex forest that has developed over a long period of time and is relatively untouched b
y human activity
No, mountains have lots of different ecosystems that change with elevation
CORRECT ANSWER Was pre-eruption MSH a homogenous species?
,May 18th, 1980 CORRECT ANSWER Mount Saint Helens erupted on...
Lateral CORRECT ANSWER What kind of explosion was MSH?
Northern slope CORRECT ANSWER
The explosion of MSH heavily affected the of the volcano.
Snow acted as a buffer CORRECT ANSWER
Following MSH's eruption, there were small surviving plants and animals because of which
buffer?
Pyroclastic flow/pumice plain CORRECT ANSWER
Most highly impacted plain of MSH; adjacent to the volcano (north); there were no remnan
ts
Blown down zone / lateral blast CORRECT ANSWER
The majority of the area affected by MSH's explosion is referred to as the
.
Blown down zone / lateral blast CORRECT ANSWER
This is the largest area affected by MSH's explosion, and it consisted of miles of forests; tre
es remained on their sides. Some lifeforms underground possibly survived.
Spirit lake CORRECT ANSWER
a lake clogged with trees and ash on MSH; contains hot springs
Pumice plain CORRECT ANSWER
Following the explosion of MSH, everything in the was covered up to
6 feet of tephra/volcanic ash.
, No, it is devoid of nutrients, so the area impacted by the volcanic ash became dust
CORRECT ANSWER Does tephra/volcanic ash contain a lot of nutrients?
Plant dispersal CORRECT ANSWER
how seeds and spores are spread from the parent plant
Wind dispersal CORRECT ANSWER
The type of dispersal that blows and can carry seeds long distances but the seeds land at r
andom; seeds must also be small and light.
Seed coat, cotyledon, and embryo CORRECT ANSWER What are the 3 parts of a seed?
Protects seed from being eaten by insect, could stay intact if pass through digestive system,
resists being crushed and losing dampness CORRECT ANSWER
3 advantages of a thick seed coat
Faster germination CORRECT ANSWER 1 advantage of a thin seed coat
Cotyledon CORRECT ANSWER
A "seed leaf" which develops as a part of the seed. It provides nutrients to the developing
seedling and eventually becomes the first leaf of the plant.
(*food storage as fats and oils*)
Peanut CORRECT ANSWER example of cotyledon
Too large to be eaten, stores more energy, lasts longer before germination, more likely to s
urvive, can grow quickly CORRECT ANSWER 5 advantages of a large cotyledon
Cannot disperse far CORRECT ANSWER 1 disadvantage of a large cotyledon
