Describe how brine pools function

Biology

Explanation:

Brine pools are sometimes called sea floor "lakes" because the dense brine does not easily mix with overlying seawater. The high salinity raises the density of the brine, which creates a distinct surface and shoreline for the pool. When submarines dive into brine pools, they float on the brine surface due to the high density

Answer:

$P=750 e^{0.00963t}$

The population size would be 753,190 after 30 days

Explanation:

Since, the population growth function is,

$P = P_0 e^{rt}$

According to the question,

if t = 0, P = 750,

$\implies 750 = P_0 e^0\implies P_0 = 750$

Also, if t = 72, P = 1500,

$\implies 1500 = P_0 e^{72r}\implies 1500 = 750 e^{72r}\implies 2 = e^{72r}\implies \ln 2 = 72r\implies r = \frac{\ln 2}{72}\approx 0.00963$

Hence, the required function would be,

$P=750 e^{0.00963t}$

If t = 720 hours ( 30 days = 720 hours ),

Then, the population after 30 days would be,

$P=750 e^{0.00963\times 720}=750 e^{6.912}=753190.30695\approx 753190$

What provides evidence of an increase in animal species at the same time that atmospheric oxygen concentrations increased?(1 poi

hammer [34]

Answer:

stromatolites

Explanation:

"stromatolites is a calcareous mound built up of layers of lime-secreting cyanobacteria and trapped sediment, found in Precambrian rocks as the earliest known fossils, and still being formed in lagoons in Australasia"

Ancient cyanobacteria present in stromatolites are considered as key factor for the increased amount of oxygen in atmosphere. Furthermore, these were considered as first organisms to trap carbon dioxide and release oxygen by the process of photosynthesis.
