<u>Answer:</u>
The first step in allopatric speciation is "geographic isolation".
<u>Explanation:</u>
Allopatric speciation happens when a population is geographically separated therefore also termed as "geographical isolation", it is also the very first step. In the laboratory, for instance, an isthmus that divides an ocean or fruit flies. The cultures on both ends of the barrier can not then balance one another, so each population develops independently.
Different geographical fluctuations may occur, such as continent movement and the creation of mountains, islands, water bodies, or glaciers. Human activity such as farming or growth can also alter the allocation of population groups of species.
Answer:
mutations, gene flow, and reproduction
Answer: The protein is translated on free ribosomes and then passes through the pore complex to enter the nucleus.
Explanation:
The answer is 10 O2, it should de 13 O2.
To know if a reaction is well balanced between the reactants and the products, you have to calculate the number of atoms of each element on both sides of the reaction and to check if they are equal.
*For carbon, on both sides, there are 8 carbon atoms.
*For hydrogen, on both sides there are 20 hydrogen atoms.
*For oxygen, there are 20 oxygen atoms in the reagents and 26 in the products, so it is necessary to increase the number of oxygen in the reactants (without touching the others). For this we put 13 O2 in the reactants instead of 10, to have 26 oxygen atoms on each side.
