A bee buzzes inside a flower to drink some nectar. While there it touches the stamen. Later the bee goes to another flower and comes into contact with the flower's pistil. Which process of reproduction is this helping with?

QUESTION

A bee buzzes inside a flower to drink some nectar. While there it touches the stamen. Later the bee goes to another flower and comes into contact with the flower's pistil. Which process of reproduction is this helping with?

ANSWER

The bee is helping in pollination which is an important event in case of sexual reproduction in flowering plants.

Pollination is a part of pre-fertilisation ( gamete transfer ).

Pollination by insects ( most commonly bees ) is known as Entamophily

answer : third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol

explanation :

let us write down the given equations

equation 1 :

equation 2 :

equation 3 :

let us use hess's law to find out which 2 equations can be added to get the third equation.

let us reverse equation 2 and multiply it by 2. the new equation that we get is,

equation 4 :

let us add equation 1 & 4

the above equation is similar to equation 3 but has different value for dhrxn.

therefore third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol
