Answer:
a. Biomagnification
Explanation:
Biomagnification is the name given to the progressive accumulation of substances from one trophic level to another along a food chain. Thus, the substance will have its highest concentration in individuals who occupy trophic levels furthest from producers.
For biomagnification to occur, substances must be fat soluble (lipid soluble) and thus adhere to living tissues. Another feature of substances that undergo biomagnification is that they are generally not biodegradable or metabolized by the body.
The phenomenon is quite common with heavy metals (lead; mercury) and certain chlorinated and aromatic organic compounds with higher molecular mass, such as the insecticide DDT.
The answer is A.
Twins form in one of two ways:
Identical twins occur when a single fertilized egg splits into two.
Fraternal twins occur when two, separate eggs are fertilized by two, separate sperm.
Photosynthesis is a process when the plants is absorbing sunlight to use the sunlight to make energy for them.
Photosynthesis equation :
6CO2 + 6H2O -> C6H12O6 + 6O2
Carbon dioxide + Water -> Sugar + oxygen
Answer:
we'll use () to indicate the different boxes
( ) (r) (r)
(R) (Rr) (Rr)
(R) (Rr) (Rr)
You will have a 2 by 2 cell for your answer. One set of your test (rr) will go across the top as is shown and the other will be vertical (RR) as shown. Go down the line and put the letter you see at the top in each box and then do the same going across.
( ) (r) (r)
( ) (r) ( )
( ) (r) ( )
( ) (r) (r)
(R) (Rr) (R)
(R) (r) ( )
I tried to make this a comprehensible as possible but just draw your diagram and put the letters in the exact order as shown and then read this. It may make more sense that way.
