The correct answer is option D that is, moving bits of rock and soil from one place to another.  

Erosion in earth science refers to the activity of surface procedures, like wind or water flow, which removes the rock, soil, or dissolved substance from one location to another location of the Earth's crust. This natural phenomenon is a result of the dynamic activity of erosive agents, like ice, water, snow, plants, wind, animals, and humans.

kari74 [83]

Answer:

(D) Enzymes can function only within living cells.

Explanation:

<em>Enzymes are biological molecules that are proteinous in nature and speed up the rate of biological reactions.</em>

Option A is true because enzymes are not used up or changed when they are used to catalyze reactions

Option B is true. Enzymes are very specific with regards to the reactions they take part in.

Option C is true. Some enzymes contain non-protein component that assist them in their functioning. These non-protein components are called co-factors.

Option E is true. Because enzymes are proteinous in nature, they can be destroyed/denatured by high temperatures.

<em>The only untrue option is D. Some enzymes can function outside living cells. For example, the enzymes involved in digestion can function not just within living cells but also outside it. The functions of some of the digestive enzymes can be demonstrated in the laboratory.</em>

Which of the following describes how kidneys remove nitrogenous waste from the blood
photoshop1234 [79]
The correct answer is they filter urea from blood and produce urine.  
<span>
Nitrogenous wastes tend to form toxic ammonia which needs to be removed. Terrestrial animals must detoxify ammonia by converting it into a relatively nontoxic molecule-urea (it occurs in the urea cycle). The urea cycle mainly occurs in the liver and the produced urea is then released into the blood. It travels to the kidneys where is filtrated and excreted in urine.</span>
