When a Stickleback fish feels threatened, it will flare out its pair of pelvic spines and three dorsal spines, making it difficult for predators to swallow them.
Answer:
Sinkholes can occur when<u> excessive water use lowers a water table and weakens the substrate.</u>
Explanation:
There are various causes for sinkholes, but all are related to water and how this can affect the soil. One of the causes of sinkholes is the excessive use of water. Excessive use lowers the volume of water in aquifers. As a consequence, the substrates that are above the aquifer change. They can not support large amounts of weight, leading to a sinkhole and soil with low permeability.
Out of the following given choices;
<span>A. </span>Salt tablets
<span>B. </span>Bee pollen
<span>C. </span>Carnitine
<span>D. </span>Coenzyme Q10
<span>E. </span>None of the above
The answer is D. (none of the above). These elements are found naturally in nature and in our bodies. Coenzyme Q-10 and carnitine are found naturally in our bodies while bee pollen and salt are found naturally in our environments. Therefore, it is implausible to consider them ergogenic substances
This could be the different times you did the experiment
I think the second option is the best (by making the ramps height and length equal) because the first option will require more pushing, the third option will only make the ramp lighter which could cause it to not stay in place, the last option would make it harder to push the boxes up because the rubber will make it harder to slide the boxes up. I hope this helps:)
