Which traits are likely to be different alleles of the same gene? check all that apply.

•thick eyebrows and thin eyebrows
•a large nose an oval face
•curly hair and straight hair
•blond hair and curly hair

The correct answers would be:

A gene is defined as a protein coding sequence of nucleotides which controls the phenotype of a particular character.

Usually, a gene exists in two alternative forms which are termed as alleles. The alleles control different phenotypes of the same character.

For example, tall and short plant, round and oval shape of a pea, green and yellow pea color, et cetera.

Similarly, Thick and thin eyebrows and curly and straight hairs are examples of alleles of a gene.

In contrast, large nose and oval face are two different characters which are controlled by two different genes.

Similarly, blond and curly are two characters of hairs (color and type) and thus, they are controlled by different genes.

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c
