DNA is a long polymer with deoxyriboses and a phosphate backbone. Has four different nitrogenous bases: adenine, guanine, cytosine, and thymine. RNA is a polymer with a ribose and phosphate backbone. Four different nitrogenous bases: adenine, guanine, cytosine, and uracil.
Every species exhibits variations based on various genes being activated at various times. An example with humans can be eye color or hair color. What species means is that all members of a species can procreate with healthy, capable of procreating progeny, but anything else is just a variation.
The plant
cells vacuole is larger compared to the animals cells' because the plants
vacuoles takes up 90% of the cells volumes. Vacuole stores food for the
