Totally. Earth's climate systems are driven by the electromagnetic radiation that comes from the Sun. The incoming radiation that comes from the Sun is reflected by the clouds, passes through Earth's surface, or is even absorbed by the planet's atmosphere. The atmosphere warms thanks to the chemical reactions of larger aerosol particles in the atmosphere absorbing this radiation.
The correct answer is - Its electrons are used to form NADPH.
On receiving light energy, electrons are expelled from the reaction center of photosystem II. The expelled electrons finally reduces oxidized NADH⁺ to NADH. The oxidized reaction center of photosystem II split water into protons, electrons and oxygen. The electrons released from water reduces oxidized reaction center of photosystem II. Thus, oxidized reaction center of photosystem II gets back its expelled electrons. Therefore, electrons from water forms NADH.
Answer:
I think you're referring to the Metaphase...
Explanation:
During Cell Division (or, rather before!) the DNA needs to be replicated. This normally is done by DNA Polymerase, and results in two identical double strands (the "Sister Chromatids".
These chromatids are held together at the Centromere, which will be the heart of the "X"-shape. After that the DNA is packed into Chromosomes by winding it around proteins called Histones. If I remember correctly there are 5 different Histones.
This "Zipping Up" makes the chromosomes more visible.
As the two sister chromatids are still connected, the result is the X-shaped Metaphase Chromosome....

Answer:
<u>C. Broca's Area</u>
Explanation:
Broca’s area is located in the front part of the left hemisphere of your brain. It has an important role in turning your ideas and thoughts into actual spoken words. Broca’s area is the most active Source right before you speak.
Broca’s area also helps to pass the information to another part of your brain called the motor cortex, which controls the movements of your mouth. It’s named after a French doctor, Pierre Paul Broca, who discovered the region of the brain in 1861.
<u>Hope this helps!</u>
