Answer:
Option A, %
Explanation:
Let the allele for non freckled trait be represented by “f”
The allele for freckled trait be represented by “F”
Let us consider that freckled trait is dominant over the non – freckled trait.
The genotype for a non – freckled parent will be “ff”
The genotype for a homozygous freckled parent will be “FF”
When a cross is carried out between a non – freckled parent and a homozygous freckled parent , the following offsprings are produced –
f f
F Ff Ff
F Ff Ff
Thus, all the four offsprings have heterozygous genotype. Since we assumed that freckled trait is dominant over the non – freckled trait, all the offsprings would be freckled.
Thus, the probability of a child having freckles would be
%
Thus, option A is correct.

Answer:
The statement that is true about red currents in the thermohaline circulation is that water in the red currents contain less salt (option A).
Explanation:
Thermohaline circulation is a concept used in oceanography, referring to the oceanic circulation that depends on factors such as surface heat and salinity, as well as the density gradient that they determine.
On a map, the different currents that are part of the thermohaline circulation are usually represented with blue and red lines, where:
- <em>The blue lines represent deep, cold, dense and higher salinity currents.</em>
- <em>The red lines represent surface currents, warm, with less salt content, so they are less dense.</em>
The red currents (see image) represented on the map have less salt content, compared to the currents represented in blue.
