The dark reaction of photosynthesis is called the Calvin cycle or Calvin - Benson cycle.

It is a series of chemical reactions that occur in chloroplasts during photosynthesis.

It is also known as the light - independent phase because it happens after light energy ahs been absorbed from the sun.

It is named after scientist called Melvin Calvin who was the winner of a Nobel prize in chemistry for finding how this cycle works way back in 1961, at the university of California.

5 goals of psychology?

Svetllana [295]

1. Describe - the first goal is to observe behavior and describe.
2. Explain - While descriptions come from observable data, psychologists must go beyond what is obvious and explain their observations. In other words, why did the subject do what he or she did?
3. Predict - Once we know what happens, and why it happens, we can begin to speculate what will happen in the future.
4. Control - Once we know what happens, why it happens and what is likely to happen in the future, we can excerpt control over it
5. Improve - Not only do psychologists attempt to control behavior, they want to do so in a positive manner, they want to improve a person’s life, not make it worse.

Embryonic tissues develop during the _________ stage.

Hitman42 [59]

Embryonic tissues or germ layers develop during the gastrulation stage. Gastrulation is a process in embryonic development during which the single-layered blastula is reorganized into a three-layered(or two-layered) structure called the gastrula. Two primary germ layers(embryonic tissues) are an inner layer-endoderm and an outer layer-ectoderm. Endoderm and ectoderm interact and produce a third layer-mesoderm. Gastrulation is followed by organogenesis, three germ layers will give rise to specific tissue and organ.For example, ectoderm gives rise to epidermis and nervous system, endoderm to the digestive system and mesoderm to muscles, bones…

Acid rain occurs when sulfur dioxide is he atmosphere is oxidized in the presence of nitrogen dioxide. Acid rain is an example o

Ierofanga [76]

Answer:

A secondary pollutant

Explanation:

Pollutants can broadly be classified into two main categories based on their formation or synthesis. 1: Primary pollutants, 2: Secondary pollutants.

1: Primary pollutants

Primary pollutant can be considered as any environmental pollutant that is being directly emitted from a certain source like when we burn coal carbon di oxide is directly emitted into the atmosphere so CO2 is a primary pollutant.

Similarly sulfur di oxide or SO2 is also a primary pollutant that is emitted by the gas emissions of motor vehicles.

2: Secondary pollutants:

On the other hand, secondary pollutant is something that is not directly emitted on earth as an environmental pollutant but some how it is formed due to a reaction of primary pollutant.

Such as mentioned in the question that SO2 when oxidized in air in the presence of enzymes and water, it form H2SO4 or acid rain which directly falls on earth and incurs great amount of damage to not only living organisms but also non-living organisms such as marble buildings.

Therefore, acid rain is secondary pollutant. Please see picture for better understanding.
