Answer:
Four to six days prior to the event, Maria should consume 550 g of carbohydrate daily and decrease to 220 to 275 g of carbohydrate daily 1 to 3 days prior to the event.
Explanation:
Carbohydrate loading is for constant supply of constant energy as ATPs for the skeletal muscles cells during high intense activity, to reduce fatigue, and increase performance for upmost performance.
The main objective is to sustaining muscle contraction during intense exercise
The practice involved increase in intake of high carbohydrate meals a few weeks before the commencement of the sporting activities. This is stored as muscle glycogen, as well as in the liver glycogen and brain.
The physiology involved the conversion of muscle glycogen to glucose -6-phopahate in the liver, and its entry into Glycolysis, and Krebs’s cycle to generate ATPs.
The use of muscle glycogen during strenuous exercise reduces blood glucose uptake, and ensured that its level is at a relatively constant value for the body homeostatic conditions, without exogenous carbohydrate intake
Answer:
Phenotypic variation is the variation which appears in the phenotype or morphology of the organism. Natural selection is the mechanism of evolution in which the adapated organism to the environment is selected or highly favoured during the course of evolution.
A phenotype is the results of the genetic change which to be established in a population has to be passed on to the generation.
Since variation in phenotypic traits allows the organism to leave indifferent circumstances therefore phenotypic variation proves essential condition to natural selection.

Answer:
Exocytosis
Explanation:
Exocytosis is when a bulk of molecules exit the cell. The arrows indicate that it is leaving the cell.
Answer:
λ = 37 nm
Radiation is in the ultra violet region.
Explanation:
Given data:
Energy of photon = 5.44 × 10 ⁻¹⁸ J
Wavelength of photon = ?
Solution:
E = h.c / λ
λ = h. c/ E
λ = 6.63× 10⁻³⁴m² kg/s × 3×10⁸ m/s / 5.44 × 10 ⁻¹⁸ Kg m²/s²
λ = 19.89 × 10⁻²⁶ kg. m³ /s² / 5.44 × 10 ⁻¹⁸ Kg m²/s²
λ = 3.7 × 10⁻⁸ m
m to nm conversion.
λ = 3.7 × 10⁻⁸m ×10⁹ nm / 1m
λ = 37 nm
Radiation is in the ultra violet region because the rage of UV is 1 nm - 400 nm.
