Answer: a. glucose
PET scan results found out that cocaine addicts process glucose less efficiently compared to others like protein, carbohydrates and sucrose. The metabolism of persons addicted to cocaine are found to be slower. This condition may last up to several months.
Answer:
DNA packaging is the method to convert long DNA into condensed chromosomes. Histone protein is responsible for basic level packaging of DNA into the nucleosome. Histone proteins are positive in nature that neutralize the DNA's negative charge.
A nucleosome consists of eight histone proteins which wraps around 147 bp of DNA. Each nucleosome has linker histone which forms chromatosome.
The next level of organization is the compaction of nucleosome into approx 30nm diameter fiber due to the attraction between nucleosomes.
Then protein condensin helps in making the 30 nm chromatin fiber to condense more to become a chromosome which is 1000 fold smaller than its original length.

Oh how I remember Quandale Dingle
Such magestic face, reminds me of pringles
Many goofy stories, he would tell

So in the meanwhile, hey guys Quandale Dingle here.

Answer:
- A signal for apoptosis that comes from outside the cell is when a cell detaches from extracellular matrix. If this happens, a transmembrane signal is triggered.
- Two examples of cellular occurrences that would prompt an apoptosis signal from inside the cell are:
1. Damaged DNA
2. Increase of cytosolic calcium concentration
Explanation:
Apoptosis can be activated from an intrinsic or an extrinsic pathway. The intrinsic pathway is activated when a cell senses stress (for example, damaged DNA or high cytosolic calcium concentration) and triggers death proteins to activate apoptosis mechanism inside of it; the extrinsic pathway refers to the apoptosis triggered by signals that come from other cells. In this scenario, ligands bind to cell-surface death receptors and activates a death-inducing signal.
