According to Chargaff's rule, pyrimidine and purine occur in equal ration (1:1) in the DNA of all cells. Adenine (A) and Thymine (T) occur in equal proportion while Guanine (G) and Cytosine (C) occurs in equal proportion in the DNA of an organism. This pattern is repetitive and found in both DNA strands.

Answer: (A) The isolated chloroplasts will make ATP
Explanation:
The Thylakoid will receive hydrogen from the acid which is pumped across the thylakoid membrane, and the electrochemical proton synthesis of ATP begins in the stroma. Once the chloroplast has been transferred to the dark, high-energy electrons are loaded together with (H+) onto NADP+, converting it to NADPH.
Answer:
Characteristics used to classify stars include color, temperature, size, composition, and brightness.
Answer:
Iceland’s Eyjafjallajökull Volcano
Explanation:
Iceland’s Eyjafjallajökull Volcano eruption happened on March 20, 2010. It consisted of different stages:
- The first eruption happened in an ice-free area (1660 m high), this eruption was little but it produced lava.
- The next phase of the eruption, on 14 April, produced a 2.5 km wide caldera under the ice cap. This led to the melting of such ice, flooding the southern region, 800 people were evacuated. During this phase, the interaction between magma with water created a plume of volcanic ash and gas of over 10 km. This lasted from April 15th to April 21st.
Even though the eruption itself wasn't that big, the melting ice that flooded the surrounded area and the ashes column that blocked the air paths for almost a week, converted this event into one of the most disastrous eruptions.
I hope you find this information useful and interesting! Good luck!
