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.

Which of the following is one goal for creating transgenic organisms?
To treat and/or cure diseases
What are transgenic animals?
Transgenic animals are animals (most commonly mice) that have had a foreign gene deliberately inserted into their genome. Such animals are most commonly created by the microinjection of DNA into the pronuclei of a fertilized egg which is subsequently implanted into the oviduct of a pseudo regnant surrogate mother.
What are the uses of transgenic animals?
Applications of animal transgenesis is to obtain information on gene function and regulation as well as on human diseases and to obtain high value products to be used for human therapy.

What is blood type an example of
Answer:
blood is a type of connective tissue
Explanation:
For a certain breed of cat, short tails are dominant (1) and long tails are
recessive (1). The Punnett square below shows a cross between two parents,
What is the phenotype ratio for this cross?
T
t
Tt to
TE
A 4 long. O short
B. 2 long, 2 short
C. 3 long, 1 short
D. I long, 3 short
The phenotype ratio for the cross would be 1 long:3 short.
PhenotypesThis refers to the physical expression of genes.
Let us assume that the allele for short tail is T while that of long tail is t.
Since short tails are dominant over long tails, any genotype with T will always be expressed as short tail.
Thus, TT and 2Tt will have short tails while only tt will have a long tail, making a ratio of 3:1.

3. Blood types: House elves have the same basic blood
types that human have; A,B, AB and O.
a. If a male house elf with blood type o has children with a female house elf
who is blood type
AB, what will the phenotypic ratios of their offspring be? (show your work).
b. A male house elf with blood type A (but whose mother was blood type O) has
children with a female elf who is type B (whose mother was type A and whose father
was type AB). What percentage of their offspring should be blood type B?
c. Dobby is blood type A and Harry Potter is blood type AB. Is it possible for Dobby to give
blood to his master? Can Harry give blood to Dobby? Explain.
Answer:
a. 1:1
b. 25%
c. Dobby can give blood to Harry, but Harry cannot give blood to Dobby.
Explanation:
a. Type O blood is recessive to type A blood and type B blood.
A B
O AO BO
O AO BO
According to the Punnett square, 50% of the offspring will have the AO genotype and 50% will have the BO genotype (1/2=50%). This means 50% will have type A blood and 50% will have type B blood, as the alleles for type A and type B blood are dominant over the allele for type O blood.
b. The male house elf's genotype is AO. If his mother was type O, then she only had the type O alleles to pass down to him, so he had to inherit one. The female house elf's genotype is BO. Her mother had to have the genotype AO. This is the only way the female would have inherited type B blood. If her mother had the AA genotype, then she would've had type AA or AB blood.
B O
A AB AO
O BO OO
According to the Punnett square, their offspring have a 25% chance of displaying any of the four blood types (1/4=25%).
c. Dobby has type A blood and Harry has type AB blood. This means that Dobby can give blood to Harry, as Harry has A antigens. However, Harry cannot give to Dobby because Dobby doesn't have B antigens, so he would experience an incompatibility reaction.

Metals and minerals accumulate in specific regions on Earth due to _______ activity and as part of the rock cycle. When sustainable yield is achieved, the rate of replenishment is equal to the rate at which the resource is harvested. This means that the resource can be harvested _______. Plate motion can create the proper temperature and _______ underground for hydrocarbons to release from kerogen.
Answer: volcanic
indefinitely
pressure
Explanation:
It should be noted that metals and minerals are regarded as non renewable resources which implies that they cannot be replenished.
They accumulate as a result of volcanic activities which takes place in the Earth. The resources can be harvested indefinitely when there is achievement of the sustainable yield. Plate motion can then create the proper temperature and pressure underground that is required for the hydrocarbons to release from kerogen.
Answer:
1. Non-renewable
2. Volcanic
3. Indefinitely
4. Pressure
5. Metals are found in rocks and can be moved by erosion and rainfall. these processes carry metal away from weathered rock, causing metals to accumulate in sediments, rivers, and streams.
