Some students at a middle school conducted a laboratory investigation to learn more about the physical properties of different elements. They observed four samples and recorded their observations in the table above. Based on these observations, which sample is most likely a nonmetal?
A.
Sample 1
B.
Sample 2
C.
Sample 3
D.
Sample 4
Answer:
A
Explanation:
1. The colour is non metallic.
2. properties of metal solidness is not there, because of results of hammer experiment.
3. Physical consistency is not solid.
Etc.
From the given observations for the four samples, it can be inferred that sample A is a non-metal. This is because the given properties of sample A do not match the properties of metals. So correct option is option A.
How do metals differ from non-metals?The properties of metals are different from non-metals. The properties of metals include a high melting point, high density, malleability, and ductility. The metals are shiny and are good conductors of heat and electricity. The metallic oxides are basic in nature
The non-metals have a relatively low melting point, and low density. They are not ductile or malleable as they are brittle. Non-metal has a dull appearance. They are bad or poor conductors of heat and electricity. The oxides of non-metal are acidic in nature.

In humans, the allele for Duchenne muscular dystrophy (d) is recessive to the
normal allele (D). This is a sex-linked trait found on the X chromosome. A
woman who does not have Duchenne muscular dystrophy has four children: a
normal son, a son with Duchenne muscular dystrophy, and two normal
daughters. The father does not have Duchenne muscular dystrophy. What is the
genotype of each member of the family? If a person has more than one
genotype possible, you must list each possibility!
Answer:
Father's genotype: Xd,Y
Mother's genotype: XD,Xd (This is the only possible genotypes because if we assume that the genotype is XdXd, then all the children will be sick)
Possible genotypes are: XDXd, XDY,XdXd,XdY
