Answer: Light is absorbed during the light dependent reactions while sugar is produced during the carbon fixation or carbon dioxide assimilation reactions.

Explanation: Photosynthetic reactions are divided into two phases:

1). The light dependent reactions or light reactions occurs when plants are illuminated. The chlorophyll and other light absorbing pigments in plants absorb sunlight and the sunlight is used to split water molecule in a process known as photolysis of water. In this process, ATP and NADPH are produced.

In carbon fixation or carbon dioxide assimilation reactions, the ATP and NADPH produced in light dependent reactions are used to drive this stage. This is the second phase of photosynthesis. In this phase, carbon dioxide is incorporated into ribulose 1,5-bisphosphate in a cyclic pathway and the product of these reactions is triose phosphate sugar. The triose phosphate sugar serves as a precursor for the synthesis of glucose and starch.

A pigment solution contains compound A with 4 polar groups and compound B with 2 polar groups. You plan to separate these compou

Karolina [17]

The more polar A compound moves ahead of the less polar B compound.

Explanation:

The analytical process that involves the separation of colored substance or chemicals is named as paper chromatography, a replacement of thin-layer chromatography. In this method, there is the use of two solvents and rotation of paper at $90^0$ . It helps in isolating two complex compounds of equal polarity.

A non-polar mixture of solvent is required in the mobile phase of this method. In accordance with the retention factor of this process, the more polar compound A will go further than compound B as the solvent is non-polar.

What drives the flow of water to move from the ocean to the atmosphere?? is it

andreyandreev [35.5K]

Answer:

b. heat energy

Explanation:

Water, which is able to exist in three different states moves from one form to another. Water can move from the ocean to the atmosphere via a process called EVAPORATION. During the process of evaporation, the sun plays a major role by supplying the HEAT ENERGY required to change water from its liquid form in the ocean to its gaseous form in the atmosphere.

Water cycle of the earth helps ensure that water is not lost in any of its forms. Liquid water stored in the ocean gets evaporated as a result of heat energy into the atmosphere as water vapour.

2.) The T-Rex went extinct 65 million years ago when the meteor hit the earth.

3.) We couldn't have done anything about this.

4.) The T-Rex lived mainly in North America and Aisa, in forests with plant-eating dinosaurs.

5.) The T-Rex was tall and stood on 2 legs. the other legs were usually up off the ground for eating its prey. I had really sharp teeth for eating meat.
