4. Can you curl your tongue up on the sides? Tongue-curling in humans is a dominant genetic trait. Suppose a man who is Tt for tongue-curling marries a woman who is also Tt for this trait. What are the possible
genotypes and phenotypes of their children and the percent chance for each?

ok, so basically if both parents both obtain the same trait *Rolling tounge* it will be way more likely for the offspring/child to obtain that trait, so therefore the child will indeed obtain the trait which means the chance of the offspring getting this trait is percent- 100% Fraction- 4/4 For the genotype and Phenotype part just imput the dominate and recessive letters (Example- Aa)

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
