If the pesticide killed 78% at first and now kills only 45% dat means the effectiveness if the pesticide has reduced by 33%. This could happen only if the pesticide was left open or in non favourable condition

How many calories are in an average trick-or-treaters halloween stash?
Vera_Pavlovna [14]

The number of calories on a Halloween stash depends on the type of candies and the number of units of each. If the stash contains 5 units of each of these candies: chocolate bars, taffies, lollypops, and candy corn the total number of calories is 1,650.

Calories are the most common unit used to define the energy a specific food gives to your body. For example, an apple has 52 calories, while a banana has 89 calories.

Considering this, in a Halloween stash the calories depend on two factors:

  • The types of candies or products
  • The units of each one

Let's suppose there are 5 units of each of the following candies:

  • Chocolate bars
  • Taffies
  • Lollypops
  • Candy corn

Let's now calculate the calories

  • Chocolate bars = 220 calories x 5 units =  1,100 calories
  • Taffies = 20 calories x 5 units = 100 calories
  • Lollypops = 83 calories x 5 units = 415 calories
  • Candy corn = 7 calories x 5 = 35 calories

Add all the previous results:

1,100 + 100 + 415 + 35 = 1,650 calories in total

The red kernel color in wheat is caused by the presence of at least one dominant allelefrom each of two independently segregatin
BlackZzzverrR [31]

Answer:

100% red kernel color

Explanation:

R_B_ = Red kernel color

R_bb and rrB_ = yellow kernel color

rrbb = white kernel color

True breeding red kernel x true breeding white kernel = RRBB x rrbb

F1 genotype ratio = 100% RrBb

F1 phenotype ratio = 100% red kernel color plant.

<em>The expected phenotype of the F1 plant is 100% red kernel color.</em>
