During rest and normal activities by the body fats contribute the biggest percentage as a source of energy followed by carbohydrates and the proteins contributing the least amount of energy. However, during strenuous exercises the body mostly uses energy from the stored carbohydrate stored in the muscles in the form of glycogen. Energy may be partially obtained from blood sugar, fatty acids in the blood and also triacylglycerols in the muscles.Therefore its not true that during intense exercise fat stores are used as a source of energy.
Answer:
gills
Explanation:
They need the gills since they are first born underwater and live part of their life down there. They don't grow tails, legs, or lungs until later on
Ex: tadpoles
The answer is lysosome. It is a
membrane-bound organelle found in almost all animal cells.
They are spherical vesicles which have hydrolytic enzymes that
can break down almost all kinds of biomolecules.
Besides degradation of polymers, the lysosome is convoluted in numerous cell
processes, including secretion, plasma
membrane repair, cell
signaling, and energy
metabolism.
Answer:
I'm assuming you are referring to a population such as a forest population. Appropriate answers would be 1) for a diverse food chain. 2) so the mechanics of an ecosystem can work and have multiple sources. IF you are referring to a population such as a given population of a species, it is important to have variety so mutations can occur and genetics can mix. This kicks off the survival of the fittest and Darwin's theory's. This, of course, takes plenty of time to see any change but genetic mutation is essentially survival of the fittest. If a mutation increases survival likelihood, they are now more fit to survive, thus creating a new "weak variation" in comparison to a new "strong variation" within a species. Read below for furhter explanation on previous stated points. I really hope this helps!
Explanation:
1) Populations of consumers would struggle if there is only one producer. If there are multiple variations of any producers, it will allow the consumers to thrive since there is an abundance and variation of producers. The same can apply to consumers since there are herbivore consumers and carnivore consumers. A population of wolves would struggle if their only food source were squirrels. If rabbits and deer were in the mix, wolves would thrive a lot easier.
2) If there was only one species of decomposer within an area, the decomposition process would take much more time due to a lack of efficiency with time. If there are multiple decomposers it wouldn't be much of an issue. Same goes with scavengers. There would be a lot of waste if only on scavenger lived within an area compared to multiple.
