Answer: While active transport requires energy and work, passive transport does not. There are several different types of this easy movement of molecules.
Explanation:
<span>The angiosperms became more common during the cretaceous period. The Cretaceous period occurred almost 144 million years ago and it followed the Jurassic period. </span>
1. Enterococcus and coliforms can enter the water through feces. Although a water sample is negative for these bacteria, it could still be infected by pathogens from other sources than feces.
2. Culture media are sterilized by filtration because they could contain antibiotics or serum which deteriorate upon heat. Filtration is used in sanitation to remove large particles.
3. In the membrane filter technique, it is assumed that <span>all viable bacteria will form colonies. This means that formed colonies develop from the viable bacteria so that the number of colonies suggests the number of bacteria.
4. E. coli is negative for Citrate and Voges-Proskauer tests, and is positive for Indole and Methyl red tests.
5. The answer is yes because eo</span><span>sin-methylene blue agar is inhibitory to Gram+ bacteria.</span>
Answer:
Any sort of prexisting rock whether sedimentary, igneous, or even metamorphic rock must change under extreme conditions like extreme heat or pressure.
Explanation:
An igneous rock is a rock that has been created via cooling of magma.
A sedimentary rock is formed from sediments, whether they be natural like seashells, or other pieces of older rocks that have worn away. usually formed under pressure.
A metamorphic rock is a rock that's changed, because it was put under extreme pressure or exposed to extreme heat.
Think of the part morphic in the word metamorphic-it literally means that it morphed or that it changed dramatically.
There are two ways for a rock to become metamorphic under <u>extreme pressure</u> or <u>extreme heat</u><u>.</u> and there are two types of metamorphic rocks, <u>contact</u> <u>metamorphism</u> and <u>regional metamorphism</u><u>.</u>
Those mean pretty much exactly what they say.
If you have any more questions, ask, but i think I covered the most important parts of the answer.
best of luck
