Answer:
Sprinter hold their breath while marathon runner didn't.
Explanation:
A sprinter can use mainly anaerobic respiration during the race because a sprinters hold their breath during a race so due to lack of oxygen it takes energy from anaerobic respiration, while a marathon runner needs to use aerobic respiration because he use oxygen during their race and by using oxygen aerobic respiration is executed. So we can conclude that sprinters use anaerobic respiration while marathon runner use aerobic respiration during running.
The answer is b the Development of circulatory shock
Answer:
The above mentioned description is true for the members of kingdom Fungi. A eukaryotic organism characterized by the presence of chitin in its cell wall is called fungi. Some of the defining features of this group include the absence of chloroplast, presence of nuclei that are membrane-bound, production of spores and presence of hyphae.
Explanation:
The members of this kingdom are non motile and posses the property of decomposes. Besides it helps in the process of nutrient cycling and its exchange as it is a decomposer. The presence of chitin in their cell wall is the unique feature of the fungi that explains its presence in a separate kingdom. They are heterotrophic in nature and perform symbiotic associations. They have the ability to secrete digestive enzymes that helps in the absorption of dissolved molecules. They also serve the purpose of decomposers in the ecosystem. They have the ability to reside in extreme environments.
I would say it's A because the others don't make sense and if they were curved they wouldn't get as much sun
Nuclear Membrane separates the contents of nucleus from the cytoplasm.
Explanation:
Two nuclear membranes form a nuclear envelope that separates the nuclear contents from the cytoplasmic content of the cell.These run continuous with the endoplasmic reticulum enclose a perinuclear space in between them.The nuclear membrane contain nuclear pore that control exit and entrance of molecules coming in and leaving the nucleus.
