Covalent bonds are formed when two non metal atoms share an electron. The atoms either give up or gain an electron, due to the outer shell being unstable.
Explanation:
they differ because it doesn't hurl multi-cellular organisms if one cell dies but if a single celled organism looses its one cell that organism will die.
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
<span>Lamarck proposed that by selective use or disuse of organs, organisms acquired or lost certain traits during their lifetime. Then passed onto offspring-leading to change in species.</span>
The reason is they are afraid of being picked on by a bigger crowd therefore increasing their chances to be bullied
