A. Cellulose
Explanation:
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.
What happens to blood once oxygen hits and why?
Answer:it changes colour
Explanation:
When blood passes through the lungs, the hemoglobin absorbs oxygen from the air we breathe and turns bright red. Our heart then pumps this blood all over the body. When it reaches its destination, the oxygen is released from the hemoglobin, and the hemoglobin turns a darker red-brown.

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.

Ancient Greek philosophers spent lots of time thinking about science and imaging explanations for the natural world. What part of the scientific process did they need to do
Answer:
Experiments
Explanation:
The ancient Greek philosophers spent more time philosophising and thinking about scientific explanations to phenomena in the natural world.
How ever, they relied solely on reasoning while attempting to explain scientific observations. Contemporarily, science is highly empirical. The scientific process can only be complete when scientific observations are subjects to rigorous experiments in order go determine the actual relationship between variables and provide better explanation for scientific observations.
Hence the ancient Greek philosophers should have used experiments rather than sole reason in proffering scientific explanations to natural phenomena.
Answer:
Experiments
Explanation:
The ancient Greek philosophers spent more time philosophising and thinking about scientific explanations to phenomena in the natural world.

What is a disadvantage of a 2D model of the digestive system?
Answer:
The disadvantage of 2D model of the digestive system is that it decreases cell to cell interaction and it is not a very important biological model.
Explanation:
The 2D model does not show quality similarity and resemblance to the main digestive system and also fail to reveal the interaction of cell surfaces of each other, it does not provide the quality detail of biological systems in digestive systems and this model is not very important or relevant biological model because It does not provide quality detail.
Which list below correctly shows the levels of organization in an organism from left to right? organs, tissues, systems, cells, organisms tissues, cells, systems, organs, organisms organisms, cells, tissues, organs, systems cells, tissues, organs, systems, organism
Answer:
Cell-tissue-organ-organ system and finally an organism
Explanation:
The list that correctly shows the levels of organization in an organism is from left to right is :
Cell --> Tissue ---> Organ ----> System -- > Organism
The cell is the basic unit of life, a group of similar cells performing similar functions make up a Tissue. While tissues perform more specialized functions when compared to cells.
Tissues make up an organ while a system like Digestive system , respiratory system, reproductive system are made up of a group of organs performing similar functions. The collection of all systems make up an organism.
Hence we can conclude that the list that correctly shows the levels of organization in an organism is from left to right is Cell --> Tissue ---> Organ ----> System -- > Organism

A. small intestine
B. esophagus
C. large intestine
D. stomach
Will mark brainlest
The stomach is similar to the function of the bladder in the excretory system. The answer is D. stomach.
The urinary bladder is has inner distensible walls which enables it to serve as a temporal storage of urine up to 500 ml. Its functions also including expulsion of urine form the body.
Based on these functions, the stomach, which is an organ in the digestive system, also act in a similar capacity. The stomach also stores food temporally that are passed down from the esophagus.
See the attachment below for the diagram of the human stomach.

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
