Adam is built in a remote area to provide electricity to nearby towns what is an unlikely effect of the dam
a.) decreased farming downstream from the infertile soil
b.) increased weed growth downstream from clear water
c.) over population of species
d.) decreased aquatic life upstream from warmer temperatures

C.) over population of species

Dams are constructed over a water source that exhibit water currents the energy of which is harnessed in order to generate electricity by the movement of the water turbine. The construction of the dam is generally related to the irradication of living organisms from the terrestrial land and from the aquatic water source for the construction of the dam. Therefore, the over population of species is unlikely the effect of the dam.

the child will have heterozygous dominant chromosomes as characters of his father are dominant over the characters of his mother.

the child is heterozygous

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
