1. double-ringed bases are purines exempt from chargaff's rules complementary with each other pyrimidines 2. which of the following is not a characteristic of chargaff’s rule #1? is also termed chargaff's ratio states that t = a and g = c states that dna composition varies among species states that the ratio of adenine to thymine is equal, as is the ratio of guanine to cytosine 3. what type of bonds are formed between complementary bases? triple carbon to carbon bonds hydrogen bonds ionic bonds polar covalent bonds 4. are single-ringed bases. guanines adenines purines pyrimidines

1. Purines

2. States that DNA composition varies among species

3. Hydrogen Bond

4. Purines

Answer to #2 is a little iffy -- sorry

Explanation:

Pyrmidines have two rings

Purines have one ring

Complementary bases are connected by hydrogen bonds.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
