Brainliest In order to provide nutritional information about food, scientists must evaluate how many calories a given food has per serving.

Given what you know about chemical and thermal energy, which is the best procedure for a scientist to use to determine how many calories are in a certain food?

Burn the food and determine the change in temperature from the beginning to the end.
Dissolve the food in water and determine how it changes the boiling point of the water.
Burn the food and determine how much it raises the temperature of a known amount of water.
Dissolve the food in water and determine if it changes the standing temperature of the water.

Considering the yellow and green pea color phenotypes studied by gregor mendel: a. what is the biochemical function of the protein that is specified by the gene responsible for the pea color phenotype? (1 point) b. a null allele of a gene is an allele that does not specify (or encode) any of the biochemical function that the gene normally provides (in other words, either no protein at all or only non-functional protein is produced from it). of the two alleles, y and y, which is more likely to be a null allele? (1 point) c. in terms of the underlying biochemistry, why is the y allele dominant to the y allele? (2 points) d. why are peas that are yy homozygotes green? (1 point) e. the amount of protein produced from a gene is roughly proportional to the number of functional copies of the gene carried by a cell or individual. what do the phenotypes of yy homozygotes, yy heterozygotes, and yy homozygotes tell us about the amount of sgr enzyme needed to produce a yellow color? explain your reasoning.
