Because think about it if you see a person with their mom they're mom may have brown eyes and they may have green eyes and that's because of genetics. They don't always have to have the exact same features they may look completely different that doesn't mean that's not their offspring.

Drag each tile tile to the correct location in the equation,each tile can be used more than once, but not all tile will, be used

grigory [225]

Answer:

2C2H2 + 5O2 -----> 4CO2 + 2H2O

Explanation:

The question is incomplete, but i manage to find one question similar to this, and the remaining part is:

C2H2 + O2 -----> CO2 + H2O

To balance the equation, we need to use the priority order to balance, which is the following:

Metals > non metals > Oxygen > Hydrogen

According to this, we have non metals, oxygen and hydrogen in the above equation, let's balance first the carbon. We have 2 carbons in the products, and 1 in the products, then, we just put a 2 there:

C2H2 + O2 -----> 2CO2 + H2O

Now, the number of carbon is balanced, but the number of oxygen was altered, let's see how much do we need. We have 5 oxygens in the products, and 2 in the reactants, we can put a 2 next to the water, so the sum of the oxygens in the products will be 6, and then, a 3 in the reactants:

C2H2 + 3O2 -----> 2CO2 + 2H2O

Putting that, will alter the number of hydrogens, so we need to balance that putting a 2 in the reactants; however this will alter again the number of carbons, so we must change the number in the products for the carbon, changing the 2 by a 4:

2C2H2 + 3O2 -----> 4CO2 + 2H2O

Finally, we can change the number of oxygens in the reactants, from 3 to 5, to balance the equation:

2C2H2 + 5O2 -----> 4CO2 + 2H2O

And this is the final balanced equation

DNA can be replicated through an in vivo mechanism or a polymerase chain reaction (PCR) mechanism. Match each description to the

umka2103 [35]

Complete question from other source attached

Answer:

Explanation:

Catalyzed by DNA polymerase - both. DNA polymerase catalyzes DNA replication in the cell. However, purified versions of the enzyme are also used to synthesise DNA as part of PCR reactions

involves leading strand synthesis only - PCR. In PCR, lagging strand synthesis is not carried out because the DNA is denatured (rendered single stranded). Therefore, each strand is replicated independently by leading strand synthesis

duplicates a small fragment of the genome - PCR. Usually, to carry out PCR, small sequences called primers are used that specify the region of DNA to be replicated

duplicates the entire genome - in vivo replication - when the DNA is replicated in vivo, the entire genome is replicated. This is carried out prior to cell division so that two daughter cells can each inherit a copy of the entire genome
