A gene mutation may result in an oncogene. So during that cell's replication the gate keeper genes will no longer be able to suppress it. This results in a mutated daughter cell. If there is a subsequent mutation an a daughter cell, a tumor will be produced.
Gene mutation can also cause mosaicism and result in different phenotypes
Answer:
0.062 moles of hydrogen gas
Explanation:
We must first out down the reaction equation before we can attempt to solve the problem.
Mg(s) + 2HCl(aq) ----> MgCl2(aq) + H2(g)
Next we obtain the number of moles in 1.5 g of magnesium metal from;
Molar mass of magnesium = 24.3 gmol-1
Number of moles of magnesium= mass/molar mass = 1.5g/24.3gmol-1 = 0.062 moles
From the reaction equation;
1 mole of magnesium metal yields 1 mole of hydrogen gas
0.062 moles of magnesium metal will yield 0.062 moles of hydrogen gas
Therefore, reaction of 1.5g of magnesium metal with excess hydrochloric acid will yield 0.062 moles of hydrogen gas.
Answer:
The correct answer will be option-A
Explanation:
Chromosomal abnormalities are caused when the chromosome pair fails to disintegrate through a process called non-disjunction. The non-disjunction of chromosomes usually takes place at the anaphase I or II of meiosis I which involves the X and Y chromosomes.
The abnormality observed with 45 chromosomes or reduction in one sex chromosome or 45, XO is caused when one X copy of a chromosome is completely absent in the cell.
The cause for the loss of one chromosome is the non-disjunction during meiosis I.
Thus, option-A is the correct answer.
Answer:
c
Explanation:
the light does nothing lol and you didn't respond to a loud noise responding to it is like "running away" so that's why c is a response
<span>it will survive for long periods of time if not met with extreme conditions.actually it can crystallize itself
ur welcome
</span>
