Nitrates are used by plants to make amino acids and proteins. Most of the phosphorus cycle takes place at ground level. Phosphate is released by the slow breakdown of rocks. What two main biological processes are responsible for the cycling of oxygen?
The sickle cell pattern based on the family history of Ashleigh isan:
- Autosomal recessive pattern
Based on the given question, we cam see that in the medical history of Ashleigh's family, most of them have had the sickle cell disease which includes her grandmother, one of her uncle's six children has it too, but her father and grandfather did not have the disease.
With this in mind, the inheritance of the sickle cell disease in the family of Ashleigh is one which is autosomal recessive as it affects some people and doesn't affect others because of the pairing of the chromosome which <em>contains the sickle cell trait.</em>

Answer: "Decreasing the salt concentration of the solution lowers DNA's melting point (Tm)" is not a true statement
Explanation:
Increasing salt concentration would lower the DNA's melting point (Tm), not otherwise.
For instance:
- In 8M urea (8M means 8 Moles per dm3), Tm is decreased by nearly 20°C.
- 95% formamide at room temperature would completely denature the double stranded DNA.
Thus, higher concentration of salts like urea or formamide lowers Tm, not otherwise
Mendelian genetics one of the fundamental laws is The Law of Independent Assortment. The law states that parental traits are passed independently from parent to child. The recessive trait, vestigial Wings, occurs in an approximate phenotypic ratio of 1.3. In monohybrid Cross of heterozygous (Rr) parents the expected phenotypic ratio correlates with the given 1:3 result therefore l can conclude that the parents are both heterogeneous (Rr) for vestigial wings. Normal Wings-R, Vestigial Wings (Parent 1) Rr* Rr (Parent 2) R*R- RR- Normal Wings (Child 1) R*r Rr- Normal WIngs (Child 2) r * R - Rr- Normal Wings (Child 3) r*r- rr Vestigial Wings (Child 4) 1 Vestigial Wings: 3 Normal Wings
