<span>B is the correct answer. Multicellular organisms, as with almost all organisms, begin life as a single cell. The increase in the number of cells can be as a result of cell division or cells combining together. </span>
784109 People per sq. mi land would its people need if the population density is 3,826 people/km2.
<h3>
What is population density?</h3>
The density of individuals within a species in a given geographic location is referred to as population density. Data on population density can be used to calculate demographics and examine interactions with ecosystems, human health, and infrastructure.
The population density equation below can be used to calculate the population density of a piece of land:
Population Density = Population/ Area
The residential density is important in determining the people's thinking and culture. Engineers find it vital to forecast population growth in order to develop infrastructure that can support a large population. It is practically impossible to develop a perfect 3D model of any structure that allows the largest number of people to live without this understanding.

Answer:
Water provides hydrogen and electrons used in producing glucose.
Explanation:
Photosynthesis is process peculiar to green plants and other organisms like algae and some bacteria. Plants synthesize their own food in form of an organic molecule (glucose) by combining carbondioxide (CO2) and H2O in the presence of sunlight. They absorb light energy from the sun to power the first process called LIGHT stage, where NADPH and ATP are produced to be used in the next stage. The electrons used to reduce NADP to NADPH comes from the "PHOTOLYSIS OF WATER"
CO2 is absorbed via the stomata in the leaves of plants. The CO2 is then fixed in the stroma of the CHLOROPLAST when it undergoes series of reactions in the Calvin cycle to produce glucose. However, the glucose molecule (C6H12O6) contains hydrogen which CO2 does not possess, this Hydrogen is provided by water during the light stage where it donated it to NADP+
