All of the above because time management is about how to balance time like when to study, study schedules etc
The answer is bare rock. -Apex
The initial size of the cultured bacteria was around 2000 after an hour the bacteria count turned to 16000 with the value of n = 8000.
Given:
n = 1000 e^ (kt)
note when t = 0,
e^kt = e^0 = 1
1000*1 ar t = 0
Stepwise solution,
4000/1000 = 4 = e^(k*1)
or
e^k = 4
k = In 4 = 1.386
when n = 1000,
n = 1000 e^(!.386 t)
t = 1.5
n = 1000 e^(2.079)
n = 8000
Hence, the correct answer is (n=4000)

Answer:
The answers are B and D.
Explanation:
The co-evolution of plants and insects led to an increase in both populations due to the mutualist benefit of this relationship. As plants started to develop rewards for the insects (such as pollen and nectar) the insects started to be able to travel further and therefore colonize, then as diversification of flowers began, also the insects started to diversify in order to afford the vast amount of food for them. Insects helped plants to pollinate and plants helped insects to spread. But as insects were evolving, some mammals and birds were also doing so, therefore, plants developed fruits with seeds in order to increase their dispersal. As answer D exposes, animals not only enhanced pollination but they also provided seed dispersal.
Answer:
The difference between a stable isotope and an unstable isotope
A "stable isotope" is any of two or more forms of an element whos nuclei contains the same number of protons and electrons, but a different number of neutrons. Stable isotopes remain unchanged indefinitely, but "unstable" (radioactive) isotopes undergo spontaneous disintegration.
