Answer:
The process of making a copy of gene is called DNA replication.
Explanation:
This is a four step process. In first step, the DNA molecule which is double helical structure is unzip. This is carried out by enzyme called helicase which is also called biological scissors. Then after that DNA form Y like structure having complementary base pairs. Two strands are formed ; leading strand and lagging strands. They complementary base pairs allow the formation of new strands with help of primer. So new strand is then a copy of gene or called replicated strand.
Carbon (C) is an element
Carbon Dioxide (CO2) is a compound
Hydrogen (H) is an element
Sodium Chloride (NaCl) is a compound
A good way to tell whether something is a compound or an element, is that in a compound there is a mixture of different elements. Like in Carbon Dioxide, the symbol is CO2. This shows the carbon (C) and oxygen (O) together. I hope i worded that well enough and this helps :)

Answer:
a) the selection intensity is 21bushels/acre
b) the response to selection is 12bushels/acre
c) The heritability is 0.57 (two decimal places)
Explanation:
Given:
mean grain yield population=72bushels/acre
mean grain yield selected individuals=93bushels/acre
mean grain yield new population=84busgels/acre
a) The selection intensity is given by:
SI=mean grain yield selected individuals-mean grain yield population=93-72=21bushels/acre
b) The response to selection is:
RS=mean grain yield new population-mean grain yield population=84-72=12bushles/acre
c) The heritability of grain yield is:
H=RS/SI=12/21=0.57
