Answer:
Below
Explanation:
Heterozygous mean a dominant and a recessive gene.
S (dominant) = short needles
s (reccessive) = long needles
Parent 2 S s
Parent 1
S
s
S s
S SS Ss
s Ss ss
For an offspring to have long needles, both alleles have to be s ( recessive allele for long needle) or ss . That's only occurs in 1/4 pairing so the probability is 25%
Answer:
They both alter the pH of a solution.
Explanation:
If a strong acid is added, the pH of a solution will lower. This is because more hydrogens/hydroniums are increasing in the solution. If a strong base is added, the pH will increase. This is because hydrogens/hydroniums are decreasing in the solution.
Potential energy. The energy you gain when it is at rest.
Answer:
Nickel is extracted from nickel oxide by reduction with carbon. Nickel is a metal which react with atmospheric oxygen which is very reactive in order to protect the inner surface of metal. Carbon extract oxygen which is attached to the nickel in the form of nickel oxide because carbon is more reactive so it made a chemical bonds with oxygen and nickel oxide is converted into a pure nickel.
