To see how many atoms are in the chemical formula or element symbol, look at the subscript.
KengaRu [80]

Explanation:

To find the number of atoms in each specie, we consider the coefficient and the subscript of each of the given atoms.

1. NaCl:

Na  = 1 atom

Cl = 1 atom

2. CO₂

C = 1 atom

O = 2 atom

3. O₂

O = 2 atoms

4. C₆H₁₂O₆

C = 6 atoms

H = 12 atoms

O = 6 atoms  

For the second part;

1. 2NaCl

Na = 2 atoms

Cl = 2 atoms

2. 3CO₂

C = 3 atoms

O = 6 atoms

3. 4O₂

O = 8 atoms

4. 2C₆H₁₂O₆

C = 12 atoms

H = 24 atoms

O = 12 atoms

What is osmosis? Please help me
KIM [24]
First off, we need to understand that osmosis is typically used with the example of water---
To understand that, osmosis is taking water from a high concentration to a low concentration to make the membrane equal to one another .
Imagine you have a pea, and the pea is about to explode of water. And you have another pea that's shriveled up. You would take some of the exploding water's pea into the shriveled one, therefore making it equal. (Thats my example I like to use!)
I hope this helped!

If one is constructing a phylogeny of reptiles using DNA sequence data, which taxon (birds, mammals, amphibians or fish) might b
neonofarm [45]

Answer: If one is constructing a phylogeny of reptiles using DNA sequence data of birds, mammals, amphibians or fish, the suitable outgroup to be used are mammals due to the time of divergence from other group of organisms.

Explanation: Phylogeny is used to determine evolutionary relationship between items or organisms. A phylogenetic tree is a graphical illustration of phylogenetic relationship. In phylogeny, an outgroup represent an organism that is more distantly related to other group of organisms.

In a phylogenetic tree, outgroup stands alone. It shows that the time of divergence of that particular organism is far from other group of organisms. Outgroup is used to root a tree and sometimes represent a group that is more ancestral on a tree.

It should be noted that differences in the DNA sequences of the organisms under consideration will determine which organism will serve as the outgroup.
