Which kind of bond would occur between sodium (Na, Group IA) and chlorine (CI, Group VIIA)?
A. ionic
B. no bond
C. metallic
D. covalent
Answers
The type of bond that occur between sodium (Na, Group IA) and chlorine (CI, Group VIIA) is ionic. That is option A.
Ionic bond occurs when there is complete transfer of electrons from one atom to another in order to attain a noble gas electron configuration.
A typical example of an ionic compound is sodium chloride which is formed from sodium (Na, Group IA) and chlorine (CI,Group VIIA).
The halogens (which are Group VIIA) all have seven electrons in their outer shell. They gain an extra electron to form an ion with a single negative charge
While the alkali metals (Group IA) all have one electron in their outer shell. They lose this electron to form an ion with a single positive charge.
When complete transfer of electrons occurs, the sodium atom losses one atom to attain Neon atom configuration while the chlorine atom gains one atom from sodium to attain Argon atom configuration.
Therefore, the type of bond that occur between sodium (Na, Group IA) and chlorine (CI, Group VIIA) is ionic.

Iron deficiency is one of the most common nutritional deficiencies in premenopausal women. Iron is a vital part of hemoglobin, which carries oxygen to red blood cells. Why do you think premenopausal women need more iron than men of the same age?
Answers
So, a woman needs more iron than a man of the same age, because she is more prone to iron deficiency due to her loss of blood.
Answer:Premenopausal women shed blood as part of menstruation every month, which lowers the level of iron in the body. So, they need more iron than men and are also at a greater risk for this nutritional deficiency.

There is a large amount of variety in the eye color of human beings. Eye color variation depends on the dominant or recessive alleles. Such a broad spectrum of colors can be attributed to... A. malnutrition. B. multiple alleles. C. a lack of alleles.
Answers
Answer:
Eye color is determined by variations in a person's genes. Most of the genes associated with eye color are involved in the production, transport, or storage of a pigment called melanin. Eye color is directly related to the amount and quality of melanin in the front layers of the iris.
The broad spectrum of colors can be attributed to multiple alleles. The correct option is B.
What is variation in human traits?Variation is a word used for different traits present within the species, variation occurs due to recessive and dominant genes present in the organisms and due to mutation.
Mendel gave this theory that the alleles are given independently by the parents and one become recessive and one becomes dominant.
The difference in eye color is due to these alleles. Suppose the mother has black eyes and the father has blue eyes, the child can have both alleles, but only one will show. Mutation can also cause variation, maybe the child has totally different eyes than his parents.
Thus, the correct option is B. multiple alleles.
