It's similar in the sense that when an ecosystem is challenged above its initial capacity, so can roads be challenged over their carrying capacity. When this happens, an ecosystem/roads "break down" start worsening the function they were supposed to do and in general become worse and worse.
Answer: C
Explanation:
Pyruvate dehydrogenase complex (PDH) is covalently modified by phosphorylation by PDH kinase and dephosphorylation by PDH phosphatase.
The dephosphorylated form of the enzyme is active. Hence activators of PDH kinase like ATP, NADH and acetyl CoA inhibits the PDH reaction
PDH phosphatase is activated by Ca++, Mg++ and AMP; this will increase the rate of PDH reaction where as PDH kinase is inhibited by Ca++. When there is adequate ATP and acetyl CoA the enzyme is inhibited.
The answer is Hominids became more dependent on vision over time and less so on their other senses. <span>This statement is related to the general decrease in the importance of smell and the increasingly significant use of vision. The stereoscopic (three-dimensional) vision and the appropriate perception of the resulting depth enabled the development of visual acuity over time.</span>
Isokinetic exercise is a type of strength training. ... These machines control the pace of an exercise by fluctuating resistance throughout your range of motion. Your speed remains consistent despite how much force you exert. You can adjust the target exercise speed and range of motion to suit your needs.
