Explanation:
Hello!
In this case, since the energy implied in a heating process is computed by using the following equation:
Whereas m is the mass, C the specific heat and T the temperature. In such a way, by plugging in the given mass, specific heat and temperatures, we obtain the following energy:
Considering that the specific heat can by used by unit of °C or K because their difference is equivalent.
Regards!

Explanation:
The fuel is burning completely
Your brain has about 100 billion neurons, all of which are interneurons. Each of these neurons may receive up to 10,000 messages from other neurons and may send messages to about 1,000 more. Every day, billions of nerve impulses travel through your nervous system from neuron to other neurons or body structures. The place where a neuron transfers an impulse to another structure is called a synapse. At the axon tips, electrical signals carried through the neuron change into a chemical form. This change allows the message to cross the gap. The message then continues in electrical from through the next neuron.
Acids tend to have a pH of below 7 (which is neutral).
The only option that makes the pH statement above true is A, 6.
So the answer is with no doubt, A. 6
A
Explanation:
The coiling up of DNA with the help of histone proteins - to what is called heterochromatic regions- is part of gene regulation. This makes genes inaccessible to RNA polymerase that makes mRNA from the genes. When the genes are exposed by DNA unwinding, these genes are transcribed and the resulting mRNAs are translated by ribosomes into proteins.
The DNA never unwinds completely, but rather does so region by region, because if it does so it would become so long that it wouldn't fit in the nucleus or cell.
