I think the independent variable has to do with either the size of fish they eat or where they get their source of food, and the dependent is the amount of DDT in the egg.
Hope this is helpful!
That'd be a state of quiescence called the G0 (g-zero) phase!
Answer:
<h2>B. that have complementary sticky ends</h2>
Explanation:
The sealing of nicks between two adjacent residues of a single-strand(ss) break on a double-strand DNA and the joining of double-strand breaks.
This is enzymatically catalyzed by the enzyme DNA ligase.
DNA ligation is the joining ends of 2 DNA molecules by the enzyme, DNA ligase. DNA ligase catalyzes the formation of two covalent phosphodiester bonds between the 3' hydroxyl group of one nucleotides and the 5' phosphate group of another and it is an ATP dependent reaction.
DNA Ligation occur most efficiently between those DNA fragments that have complementary sticky ends.
The answer would be "C. Interbreeding between two populations would be impossible" Species become a species when it can reproduce with another animal of the same species and produce fertile offspring, while it can't do this with other animals.
<span> Just follow the rock cycle.
(1) Rock is broken down
(2) Regolith is eroded/transported
(3) Regolith is dumped
(4) Layers begin to compact
(5) Sedimentary rock is buried and turned into metamorphic rock
(6) Metamorphic rock melts to magma
(7) Magma resurfaces as igneous rock </span>
