Mitosis creates 'normal' body cells, while meiosis creates sex cells, like sperm and eggs. After mitosis, there are two daughter cells. After meiosis there are 4. The daughter cells from mitosis have a th...

1. thin diffusion distance- 1 cell thick 2. large surface area- alveoli 3. large concentration gradient- lots of blood vessels 4. moist

Vol = 1/3 pi r^2 h

r = 2n

h = 3n

Therefore

Vol = 1/3.pi.(2n)^2.3n

Vol = 1/3.pi.12n^3

Vol = 4.pi.n^3

The enhanced greenhouse effect is the stronger impact caused by human emissions of greenhouse gases. Greenhouse gases include carbon dioxide, methane and water vapour and are often produced by burning fos...

When confronted with an historical source, there are a few easy steps you can take to immediately assess how reliable it is. First of all, you need to decide whether the source is primary or ...
