<u>Answer</u>:

Eye colour is one example of a trait caused by the concentration of melanin in genes.

<u>Explanation</u>:

Eye colour is decided based on two distinct factors- pigmentation of the eye’s iris and scattering of the light by the 'stroma of the iris'. It is a 'polygenic phenotypic' character in a human being.

The pigmentation of the iris varies between brown and black, that all depends on melanin concentration in the iris stroma, iris pigment epithelium and the cellular density of trauma. Further, the eye colour genetics are complicated and multiple genes are responsible for same.

Si 100 monedas tienen una masa total de 226.13g. Cual es la masa de una moneda

galben [10]

The mass of a coin : 2.2613 g

<h3>Further explanation </h3>

Algebraic expressions in mathematics are a combination of coefficients, numbers, variables, constants and arithmetic operations such as addition, subtraction, multiplication, and division.

The main composition of algebraic expressions are:

1. phrases

algebraic forms separated by arithmetic operations

consists of one phrase (monomial) to many phrases (polynomial)

2. variables

is a value that can be changed, can be in the form of letters, for example, x, y, a, b, etc.

3. constants

is a fixed value, can be a number

4. arithmetic operations ⇒ +, - , : , x

<em>If 100 coins have a total mass of 226.13g. What is the mass of a coin</em>

We can make this statement in the form of an algebraic equation :

100 coins=226.13 g

then the mass of a coin :

$\tt \dfrac{1}{100}\times 226.13~g=2.2613~g$

The freezing point of a substance is -20°C. Its boiling point is 120°C.

Tasya [4]

Answer:

a. liquid

b. solid

c. gas, (should be at it's boiling point)

Explanation: If the normal melting point of a substance is below room temperature, the substance is a liquid at room temperature. Benzene melts at 6°C and boils at 80°C; it is a liquid at room temperature. If both the normal melting point and the normal boiling point are above room temperature, the substance is a solid.
