Antarctic fish species requires an adaptation to cold environment. Living at cold temperature environment would demand certain biological responses such as cutaneous respiration, enlarged blood vessels, and producing greater amounts of fat. Most of these fat are composed of higher phospolipid levels which are primarily due to phosphatidylethanolamine. This phospolipid is responsible for destabilizing cell membranes and make it more fluid thereby allowing unrestricted blood flow. The fatty acid composition of the membrane lipid is important for membrane fluidity, this is mainly attributed to unsaturated fatty acids which are responsible for decreasing the order of membrane lipids thereby decreasing viscosity. At extremely low temperatures, organisms with low concentration of unsaturated fatty acids would freeze cell membranes. That's why antarctic fishes have higher levels of unsaturated fatty acids.
B.Liquid Water
Explanation: lava gushes out ashes go up and gases when it erupts only water does not erupt.
cellular respiration releases the greatest amount of energy or ATP.
Explanation:
In cellular respiration 38 ATPs in the process. 4 molecules of ATP are formed in glycolysis, 32 molecules in Oxidative phosphorylation.
alcoholic fermentation: 2 ATP is formed
lactic acid cycle: 2 ATP is formed
photosynthesis: does not produce ATP instead ATP formed from the glucose formed is used in the process.
The right answer is to measure the amount of released carbon dioxide.
The carbon dioxide exhaled by the lungs can reflect the energy consumed by the body since it comes from the degradation of glucose which is the main energy substrate. And this is a better indicator of energy consumption than measuring heart rate because it can be inflected by several factors.
A is false because glucose is not found in the urine, except in the case of diabetes mellitus.
C is false because the consumption of calories does not mean that we will directly use it.
D is wrong because perspiration is independent of energy consumption, this is a way to cool the body after exercise.
Explanation:
A hypothesis is defined as an educated guess , while a research question is simplify a research wondering about the world .
