Good luck on your assignment
______________________________
Rabbits can be best described as primary consumers. The correct option is b.
What are primary consumers?The 2nd trophic level is comprised of primary consumers. They are also known as herbivores. They just feed primary producers, including such plants or algae. A grasshopper, for example, is a primary consumer in the Everglades.
Primary consumers are rabbits because they are the first step up from autotrophs. Autotrophs, such as grass, are eaten by primary consumers such as rabbits.
The animals that eat the primary consumers are known as secondary consumers.
Herbivores are the primary consumers of plants. Primary consumers include caterpillars, insects, grasshoppers, termites, and hummingbirds, which only eat autotrophs (plants).
Rabbits are herbivores because they only eat plants - and herbivores are consumers because they eat plants to survive. Consumers include deer, grasshoppers, and rabbits.
Thus, the correct option is b.

Answer:
Dopamine, Acetylcholine, Serotonin
Explanation:
Answer:
One common neurotransmitter is dopamine. It is an excitatory neurotransmitter that is involved in movement, learning, attention, and emotion. GABA is another common neurotransmitter, and it is a major inhibitory neurotransmitter. It is involved in anxiety, arousal, and sleep. Glutamate is a major excitatory neurotransmitter, and it is involved in learning and memory.
Acetylcholine: Serves as a messenger between each motor neuron and skeletal muscles, which accounts for its role in helping to control skeletal muscles.
Serotonin: Affects sleep, hunger, mood, and arousal; connected to aggression and abnormal behavior
Norepinephrine: Helps control arousal and alertness; helps in regulating mood

Answers
Answer:
Well, background radiation is used to determine how the universe was made, in this case, The Big Bang, if microwaves were visible, astronomers would be able to determine the age. Microwaves would be between orange-red, it might get brighter.
Explanation:
Hope this helps.
The bright and astonishingly uniform color of microwave radiation would : make background radiation visible to astronomers studying the age of the universe ( using the Big bang theory )
The Big bang theory is a cosmological model that proposes that the new universe was formed from the expansion of a Larger body having a high level of density and temperature.
The background radiation is a microwave radiation that is studied by astronomers to determine the age of the universe, therefore if microwave radiation has a bright color it will help the astronomers determine the age of the universe easily and also proving that the formation of the universe was from the Big bang.
Hence we can conclude that The bright and astonishingly uniform color of microwave radiation would : make background radiation visible to astronomers studying the age of the universe ( Big bang theory )

Some students used information they gathered from lab investigations to prepare a table. They entered the table in their lab notebooks. Which of these correctly identifies the two cells described in the table? Your answer: Cell 1 is eukaryotic, and Cell 2 is prokaryotic. Both Cell 1 and Cell 2 are prokaryotic. Cell 1 is prokaryotic, and Cell 2 is eukaryotic.
Answers
Answer:
Cell 1 is prokaryotic, and Cell 2 is eukaryotic.
Explanation:
All living cells have been classified into two major domains; Eukarya and Prokarya. This classification was done based on the possession or not of an enclosed structure that houses the genetic material of the organisms called NUCLEUS. Eukaryotic cells possess a membrane-bound nucleus that houses their DNA while prokaryotic cells do not have a membrane-bound nucleus, hence their DNA is found naked in a region of the cytoplasm called NUCLEOID.
In addition to this primary basis (nucleus possession), eukaryotic cells have a linear DNA and other membrane-bound organnelles like mitochondria, Chloroplast, Endoplasmic Reticulum etc while prokaryotic cells have a circular single DNA and have no membrane-bound organnelles.
Based on this comparison, cell 1 is a prokaryotic cell while cell 2 is an eukaryotic cell.
