The ages of rocks that contain fossils can be determined using the isotope 87Rb. This isotope of rubidium undergoes beta
AVprozaik [17]

Answer:

Age of rock = 722 million years old

Explanation:

Using the formula; <em>fraction remaining = 0.5ⁿ</em>

where n = number of half lives elapsed.

However, from the given values, fraction remaining = 1.000 - 0.0105

fraction remaining = 0.9895

Substituting in the formula to determine the number of half-lives:

0.9895 = 0.5ⁿ

log 0.9895 = n log 0.5  

-0.0045842 = -0.30103 n

number of half lives elapsed, n = 0.0152

Therefore age of rock = 0.0152 x 4.75 x 10¹⁰ years =  7.22 x10⁸ years

Age of rock = 722 million years old

For a specific enzyme/substrate system, which condition will always result in an increase in Vo (assuming nothing else changes)?
inessss [21]
<span>a decrease in Km and an increase in Vmax
 km is the constant that relates how thick the volume of the substrate in terms of concentration when the speed is a large portion of the most extreme. They increment Km by meddling with the joining process that makes them stick together wit the substrate, however they have any effect with regards to Vmax since since the sticking process to ES did not occur</span>
