Nutrient cycle is the biogeochemical cycle that<span> includes exoskeleton and shells of marine organisms as a reservoir. This cycle involves the exchange of organic and inorganic matter back to the living production of matter. The decomposition of exoskeleton and shells of marine organisms will give nutrients which will be used in this cycle.</span>
Summary. Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.
Answer:
<u>Definitions:</u>
endothermos: An ectotherm (reptile/amphibian) relies primarily on its external environment to regulate the temperature of its body.
ectothermos: Endotherms (birds) are able to regulate their body temperatures by producing heat within the body.
<u>Examples:</u>
endothermos: People, polar bears, penguins, and prairie dogs, like most other birds and mammals.
ectothermos: reptiles, amphibians, crabs, and fish.
Attached is the image concerning the HOXD13 gene along with the regulatory and promotor regions of the gene.
The answer will be "yes; when any of the segments of deleted, the expression level dropped to less than 100% of the control."
The experiment comprises of testing the expression of the HOXD13 mRNA from the gene by deleting segments of the regulatory regions. In the event of deletion of one segment (segment C), the mRNA expression dropped to around 60% of the control. When two segments are deleted (segments B and C), the mRNA expression dropped to less then 40% of the control. When all segments are deleted, the mRNA expression was almost to 0%.
They're separated based on how they get their energy. Plant-like protists get their energy from the sun-- they're producers. Animal-like protists feed off of producers-- they're consumers. Fungus-like protists are decomposers because they get their energy from dead organisms.
