Having freckles is dominant (F) and not having freckles is recessive (f), A mother has Ff and a father has Ff , if they have a child which genotype will make the child have freckles

For the child to have freckles his genotype must be FF of Ff

Explanation:

Since freckles is dominant (F) and not having freckles is recessive (f), If the child has a genotype with at least one dominant gene (that is FF, Fr) , the child would have freckles but for the child not to have freckles, the genotype gene must both be recessive (that is ff)

Since the other has Ff and a father has Ff, if they have four children, the children genotypes would be FF, Ff, Ff and ff. Since freckles (F) is dominant for the child to have freckles his genotype must be FF of Ff

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .

let that person have a turn to speak : )
