Answer:
Phenotypic ratio - 3 Freckes : 1 No freckles
Explanation:
This question represents a monohybrid cross i.e. involving a single gene coding for possession or not of freckles. The allele for possession of freckles (F) is dominant over the allele for no freckles (f).
In a cross between two HETEROZYGOUS parents i.e. Ff × Ff, each parent will produce gametes with alleles F and f respectively. Using a punnet square (see attached image), four possible offsprings will be produced with genotypes: FF, Ff, Ff and ff.
Based on this genotypes, the phenotypic ratio of the offsprings will be 3:1 where 3 offsprings will possess freckles and 1 will have no freckles.
If the patient weight is 250 lb and the doses are 0.8mg/kg/hour for 12 hours, then the total amount of theophylline needed would be:
250lb * 0.453592kg/lb* 0.8mg/kg/hr * 12hr= <span>1088.6208mg
If the solution contains 800mg of </span>theophylline for 100ml volume, then the volume needed would be: 1088.62 mg / (800mg/100ml)= 136.07ml
Answer:
Animals in Namibia are organized by their conservation in different zones of this place.
Explanation:
The huge diversity in Namibia’s eco system made it the richest place of South Africa in terms of species that this place have. This ecosystem has endemic species with a number of 14 in it.
To organise these species three biotic sectors in Namibia are utilized, they are- The Southern Savanna, the Southwest Arid and Dessert of Namib.
The wetland ecosystem of Arid is important for many species and the mammals also. The elephant of desert and the black rhinos belongs to the Namibia Dessert ecosystem.
Histamine in Digestion Histamine plays a role in gastric secretion by helping to induce the production of acid in the stomach. Histamine in sleep: the body regulates the amount of histamine in circulation and maintains a careful balance.
