The observed trait of the individual rabbitis referred to as the phenotype.
Organisms receive a set of genes from their parents. This set of genes that an organism receives from its parents is called the genotype of the organism.
However, genes occur in pairs called alleles. In a pair of alleles, one gene is dominant while other is recessive. The dominant gene determines the expressed traits of the individual organism.
This expressed trait of the individual organism as determined by the dominant gene is called the phenotype of the organism.

Answer:
Phenotype
Explanation:
Phenotypes are traits that can be seen or observed by the human eye.
The correct answer is A) They all have similar chemical properties.
Explanation:
In chemistry, the periodic table organizes visually the chemical elements. In this, elements are arranged according to different features. In the case of families of the elements, these refer to elements organized in the same column, for example, elements that are in column 18 form a family called noble gases.
These elements form a family because they have chemical properties; in the case of noble gases, this includes similar reactivity and physical features such as color and odor. Besides this, the elements of one family share a similar electron configuration but not the same number of electrons. This means, from the options given the one that identifies the elements that belong to a family is "They all have similar chemical properties".
Each set of elements has an equal number of electrons in the outer orbital. We refer to these as valence electrons. Each element's chemical characteristics are determined by its valence electrons. The correct option is A.
The elements in the same group or column of the periodic table are those whose chemical characteristics are the most comparable. The vertical groups of elements that have the same number of valence electrons and, consequently, comparable chemical characteristics are formed when the elements are arranged in order of atomic number.
Only when matter changes to become a completely other sort of matter can chemical characteristics be measured or observed. They consist of flammability, reactivity, and rusting potential.
Thus the correct option is A.

Answer:
Br,Ga,Cl?
Explanation:
0.75 mole of H2CO3 = 47 g
3.42 moles CO = 95.8 g
4.1 moles Li2O = 94 g
Answer:
4.1 moles Li2O = 94 g (incorrect)
4.1 mole of Li2O = 122.6g(correct)
Explanation:
1. Molar mass of O2 = 32
0.2 mole of 32 = 0.2×32 = 6.4g (correct)
2. Molar mass of H2CO3 = 62.03
0.75 mole of 62.03 = 0.75×62.03 = 46.5g (47 is correct)
3. Molar mass of CO = 28
3.42 moles of 30 = 3.42×28 = 95.76 (95.8 is correct)
4. Molar mass of Li2O = 29.9
4.1 mole of Li2O = 4.1×29.9 = 122.59g (94g is incorrect)
Answer:
It's 4.1 moles Li2O = 94 g on Odyssey ware
