Answer:

b. photosynthesis in which water photolysis produces H , e , and O2 is the correct answer.

Explanation:

  • Cyanobacteria is the oxygenic microbes that produce oxygen by a process called photosynthesis.
  • Photolysis is the process  by which water molecules split into oxygen and hydrogen during the light reaction of the photosynthesis process.
  • Cyanobacteria produce their food by photosynthesis.
  • Cyanobacteria has chlorophyll that converts carbon dioxide to sugar by carbon fixation.
  • Cyanobacteria perform photosynthesis by using carbon dioxide, sunlight, and water to produce oxygen and carbohydrates.
  • Thus cyanobacteria utilize the energy from light to split the water molecule and produces H, e , and O2.

What are two quantities In a proportional relationship AND what is a proportional relationship?
ankoles [38]

Answer:

Do you have a friend that can affect your mood? Whenever she's up, you're up. When she's down, you're down. A proportional relationship between quantities is a lot like that. For example, imagine a beehive that has a lot of bees in it. Each of those bees has six legs. If I take away half the bees, there will only be half as many legs left in the hive as well. There is a proportional relationship between the number of bees and the number of bee legs in that hive.

A proportional relationship exists between two values x and y when they can be expressed in the general form y = kx, where k is the constant of proportionality.

Our beehive example could be represented by y = 6x, where x is the number of bees, y is the number of legs, and k is 6 (since each bee has 6 legs). If I double x, then y will also double, and if I divide y by x, then y/x should always be 6.

Another way to say that is if two values are proportional, then dividing them by each other will always produce the same ratio. This ratio will be the constant k, which can be expressed as a fraction or a decimal.

How is the cultural diversity of the Eastern Mediterranean reflected in the Old City?
xeze [42]

Answer:

archaeological

Explanation:

The 4th to 6th centuries CE were a time of natural disasters including plague, earthquakes, and climatic instability, as well as warfare and invasions. Yet archaeological evidence demonstrates that in this period rural village communities in the eastern Mediterranean flourished, with new building, settlement of marginal land, high levels of agricultural production, and wide export of their products. In seeking to explain the vitality of the Eastern Mediterranean countryside in spite of manifold shocks, this article applies Community Resilience Theory, a body of research on the internal socio-economic capacities that have enabled communities in the contemporary world to successfully bounce back from crisis. By examining the archaeological remains of late antique eastern Mediterranean rural communities, we can see beyond the constraints of elite textual accounts to the lives of ordinary people in these flourishing villages. Material remains which attest a high volume and diversity of economic activities, a degree of equitable distribution of income, effective routes of communication, the existence of social capital, and capacity for cooperation and technological innovation reveal how the people of these communities might have acted as historical agents in determining their own fate.
