How do amoebas obtain energy?Eukaryotes and Prokaryotes:Amoebas are single-celled organisms with a eukaryotic cell. This means they have membrane-bound organelles including a nucleus. If a cell does not have membrane-bound organelles, it is prokaryotic. This is common among bacteria.Answer and ...
How do animals obtain oxygen? Do plants perform cellular respiration? Explain why or why not. What is one way in which energy flow differs from chemical cycling? How do chloroplasts get energy from sunlight? What structures allow plant cells to access food energy?
roundworms do not use lungs to move the oxygen around their bodies. Roundworms absorb oxygen and release carbon dioxide directly through their cuticle, which is permeable to both gases. Once oxygen has crossed into their bodies, it diffuses through...
Therefore, the limit of adaptability to heat without deteriorating intellectual productivity was determined by measuring the cerebral blood flow during heat performance of the subject with a tissue oxygen monitor using near-infrared spectroscopy. We further investigated whether semantic differences in ...

Sponges do not have nervous, digestive or circulatory systems. Instead, most rely onmaintaining a constant water flow through their bodies to obtain food and oxygenand to remove wastes. Are sponges aerobic? An anaerobic world in sponges. Until recently, sponge metabolism was viewed as being based...
Science instructors need questions for use in exams, homework assignments, class discussions, reviews, and other instructional activities. Textbooks never have enough questions, so instructors must find them from other sources or generate their own quest
How do bivalves obtain food?Bivalves:There are over 15,000 different species of bivalves, which are invertebrates classified in the phylum Mollusca. All bivalves have a two-part shell that is connected with a hinge. Examples of bivalves include scallops, clams, and oysters. There are both ...
How do humans obtain food energy? Describe how the cardiovascular system compensates when an individual goes from a supine position to a standing position. How does the skin respond to external stimuli? How is heart rate modified according to the needs of our body?
"All cells produce these molecules, but sperm tend to produce more, probably because they have such fast metabolisms. What's more, reactive oxygen molecules are thought to accelerate aging in all cells. So it follows that getting rid of free radicals might extend the lifespan of sperm," say...
