Option B

Primary productivity is not limited by time

<u>Explanation:</u>

To ecosystems, the productivity of the primary producers is essential because certain bodies generate energy for different existence bodies. Besides the era, primary production ends in the extension of dissimilar plant biomass to the practice. Consumers acquire their strength from primary producers, unless directly (herbivores, any detritivores), or diffusely.

It depends superimposed on the availability of the sunlight, availability of the nutrients such as nitrogen, iron, phosphorus from the soil and water. The primary productivity of the plant's distinct autotrophs is not restricted by time.

What is the pH of [H+]=0.0000000035 and is it acidic, basic, or neutral?
natima [27]

Answer:

The pH is 8,45 and it is basic.

Explanation:

The pH is a measure that gives us an idea of the acidity or alkalinity of a solution. It is calculated as:

pH = -log (H +)= -log (0.0000000035)=8, 46

The pH scale ranges from values of 0 to 14 (less than 7.0 is acidic and greater than 7.0 is basic, a pH = 7.0 is neutral).

In this case, the solution is basic (value greater than 7.0 ).

STatiana [176]

The average atomic mass of oxygen is 16 amu.

According to the formula of average atomic mass of oxygen

= \frac{Sum of (Mass of each isotope)(relative abundance)}{100} \\\\= \frac{((16)(99.76)+(17)(0.037)+(18)(0.204)}{100} \\\\=16 amu
