Cohesive. This means that the water is attracted to other particles of itself, so they stick and bead up.
<span>F- allele for freckles
f- </span><span>allele without freckles
1) The man is heterozygote and has freckles, its indicating that the allele for freckles is dominant.
A cross between him and a woman who is also </span><span>heterozygote: Ff x Ff
it would result in the following probabilities:
- 1/4 - homozygote with freckles: FF
- 2/4 - </span><span>heterozygote with freckles: Ff
- 1/4- </span><span>homozygote without freckles:ff
Their son would have a probability of 75% of being born with freckles.
2) The cross resulted in this probabilities:
</span><span><span>- 1/4 - homozygote with freckles: FF
- 2/4 - </span><span>heterozygote with freckles: Ff
- 1/4- </span><span>homozygote without freckles:ff
So, the chance of being born heterozygote for this gene is 2/4, which is the same as half (50%).

It has11 protons and neutrons atomic number=11 mass=22
NaCl: natriumchloride. 1 atom of each, so the 2 is too much and I (capital i here) is another element
So for the second excercise the number behind the symbol is the amount of atoms in the compound. So easily 2 atoms of Li, 1 atom of S and 4 of O
