I believe it is the Nitrogen cycle although all of the cycles use bacteria. Only nitrogen requires nitrogen fixing bacteria to keep the cycle going.

Why are AT pairs are easier to pull apart than GC pairs during the unwinding process
Mice21 [21]
Initiator proteins break hydrogen bonds separating short length of DNA, AT base pairs are held together by fewer hydrogen bonds than GC pair. Thus AT pairs are easier to pull apart, At rich regions are typically found in the replication origins. Replication origins are site at which DNA is first opened.

Identify the phenotypes for the offspring of a parent with the genotype IBi and a parent with the genotype IAIA. type O type A,
agasfer [191]
 <span>I is dominant, i is recessive. The A's and B's are just show which allele I is. When there is just one dominant allele, it masks the recessive in blood typing. Remember IA and IB are codominant. 

O is always ii 
A is IAi (heterozygous) or IAIA (homozygous) 
B is IBi (heterozygous) or IBIB (homozygous) 
AB is always IAIB 

Remember: You get one allele from each parent! 

1. Father must be ii, mother must be ii, so all children must be ii. 

2. Father is IAIA (the homozygous one), the mother is IBIB, so the only possibility for the children is IAIB, because you get one allele from the father and one from the mother. 

3. Father is IAi, mother is IBi, so the children can be any of the blood types, because they can have all the combinations of genotypes. 

4. Father is ii, mother is IAIB. Children can only be IAi or IBi. 

5. Father is IAIB, mother is IAIB. Children can be IAIA, IBIB, or IAIB. 

Example of Punnett square: 
3. Father is type A, heterozygous, mother is type B, heterozygous 
Father must be IAi (heterozygous) 
Mother must be IBi (heterozygous) 

_______IA ____ i 

IB____ IBIA____IBi 

i _____ IAi______ii 

Sorry, that was difficult on here, hope it's understandable. 
The father's alleles run across the top, the mother's are on the side, you follow to where they meet to find the possibilities for the children. IBIA (AB blood type), IBi (B), IAi (A), and ii (O) are the possibilities in this case. 

Hope that helps!</span>

What generally happens to the number of leaves as the leaf surface area decreases?
likoan [24]

As the leaf surface area decreases ; Number of leaves increase inmost plants.

As the leaf surface area increases, the rate of transpiration increases as well because leaves with large surface areas have bigger stomata. also the smaller the leave surface area of a plant/tree the denser the leaves the plants/tree will have.

Trees with tiny leaves tend to have a lot of leaves because of the decrease transpiration rate occurring in the leaves of the plants .

Hence we can conclude that what generally happens to the number of leaves as leaf surface area decrease is number of leaves increases in most plants.

Explain how tillage has negative effects on the environment.
Sergeeva-Olga [200]

Answer:

Soil Erosion

Explanation:

Basically, tillage breaks soil up, destroying its overall structure. It encourages surface runoff and therefore soil erodes more easily. In some cases soil erosion is beneficial, but in most cases, it is not. Tillage has also been found to cause the emissions of more toxic gases such as N20.
