1) A class collected water samples from a nearby pond and wants to observe the samples for
microorganisms. Which microscope would be the most appropriate for the students to use?
A. Dissecting microscope
B. Compound light microscope
I
C. Transmission electron microscope
D. Scanning electron microscope
Answer:
Compound light microscope
Explanation:
This is the ideal microscope because it requires the passage of harmless beam of light through the specimen.Since the pond contain living creatures this is best to use.
C and D both require the transmission of beam of electrons through a sample. D depends on the reflection of the electron after scanning the specimen surfaces and sent this to the lenses of the observer.(C)involved the passing of the beam of electrons through the specimen the interaction of the electrons with the atoms in the specimen(,therefore in both cases these specimens can not be wet and living.
The specimen should be dry in both cases and therefore non -living ,because the chamber for the specimen must be a vacuum,and living organism can not survive in the vacuum. Thus pond water can not be used as specimen because the specimen in the water but me be living.
The European Starling is an invasive species of songbird found here in the United States. The growing population of starlings has caused displacement of Eastern Bluebird from their normal nesting sites. This is an example of
interspecific competition.
intraspecific competition.
resource partitioning.
commensalism.
Answer:
Explanation:
European starlings are agricultural pests. They damage crops and berries. European starlings also aggressively compete with native birds for the insects they eat. ... Large numbers of European starlings can cause dangerous and expensive damage to jet engines when they get sucked in.
The growing population of starlings has caused displacement of Eastern Bluebird from their normal nesting sites. This is an example of interspecific competition.
what is interspecific competition?Two models Lotka-Volterra model of competition and the Tillman’s model of competition are used to describe the influence of exploitative competition among species.
Interspecific competition is defined as in an ecosystem when different types of species compete among themselves for the fixed and same resources like food, shelter, light, water, and the other essential necessities.
In such one organism may lower its population size because of not able to avail the limited resources where as other organism increase in the population and they also tend to limit the growth of that particular species.
Thus, competition occurs in two ways either at an individual organism level, namely exploitative competition and interference competition.

I am a multicellular organism. I am heterotrophic and rely on oxygen to metabolize my food. I belong to Kingdom
Answer:
Kingdom Animalia
Explanation:
Kingdom Animalia is one of the seven kingdoms living organisms are classified into. The Kingdom contains organisms called ANIMALS. They are eukaryotic i.e. possess a membrane-bound nucleus. Animals are heterotrophic i.e. they rely on other organisms for their source of energy (food).
In order to break down this food via metabolism, animals need oxygen to do so. This process is called respiration, and it yields energy in form of ATP, which is used by their cells to carry out cellular functions. Therefore, a heterotrophic multicellular organism that relies on oxygen to metabolize its food belongs to KINGDOM ANIMALIA
