Answer:
the answer is b it comes down to b and c for me
When myosin head bind to the actin, it will form a cross bridge and causes a power stroke to occur. It will hydrolyse the ATP to ADP + Pi in the ATPase of the myosin head and the myosin head will detached from actin and tilt back to its original position. Hence the sarcomere will shorten
Answer:
The non-coding regions of DNA are called introns. They are significant in evolution since they offer a great 'recipe' for recombination with genes/exons. Therefore, this offers variations among individuals on which natural selection could act upon to help a population adapt to changes in the environment. Introns also offer an additional step in gene regulation through the splicing of introns in making of mRNA.
Viruses do not have a nucleus, they cannot be recycled because they release their genetic code and that cannot be recovered unless they replicate and the problem with letting them replicate is that they have a likelihood of mutating and becoming something malicious. So by the power of deduction the correct answer is 3
Answer:
Introduction
Carbon is a very important element to living things. As the second most common element in the human body, we know that human life without carbon would not be possible. Protein, carbohydrates, and fats are all part of the body and all contain carbon.
Carbon occurs in many forms on Earth and is found throughout the environment (Figure below). The element moves through organisms and then returns to the environment. When all this happens in balance, the ecosystem remains in balance too. In this section, let’s follow the path of a carbon atom over many years and see what happens.
Explaination:When your body breaks down food to produce energy, you break down protein, carbohydrates, and fat, and you breathe out carbon dioxide.
