Answer:

a. This quote means, if you believe that something you excel, or your ability to do something, in is ingrained in your mind you will eventually get to a point where you won't know what to do or your won't be good at it anymore and you will break, and not know what to do because you think your skill was ingrained into your mind.

aivan3 [116]

Answer:

DNA ligase

Explanation:

DNA replication is an enzyme mediated, 3-step process during which the DNA molecule produces a copy of itself. The 3 steps involved are as follows;

  • initiation
  • elongation
  • termination

<em>Initiation </em>involves the unwinding of the double helix structure of the DNA using DNA helicase enzyme

<em>Elongation</em> involves binding of RNA primer to the DNA strands and addition of bases to the primer<em> </em>to elongate the new chains. Bases are added to the leading strand continuously while the lagging strand is replicated in short segments (okazaki segments).

<em>Termination</em> involves the unbinding of RNA primer and substitution of its bases by DNA bases. The Okazaki fragments are then joined together using the DNA ligase enzyme.

<em>The short, numerous segments of DNA observed in the mixture is the Okazaki fragments of the lagging strand. This is due to the absence of the enzyme involved in the joining of these fragments.</em>

Hence, the answer is DNA ligase.

How is the berries of a mountain ash, the helicopter seeds of maples and linden trees, the parachute seeds of the cottonwood tre
ehidna [41]
Well you see each of the seeds have developed a special technique that allows their individual seeds to travel further and lower the probability of landing close to the tree and not getting the sunlight it needs

For the berries birds and various animals eat them carrying them away so hopefully they can get more sunlight

Helicopter seeds do the same thing except the sides themselves float away from the tree to get  a further distance.

Finally the acorn seeds of the oak tree use the same concept of the berries. Various squirrels do eat these kinds of nuts and bury them in the ground in hopes of finding them later. But due to squirrels not remembering where they buried their acorn seeds the acorns are well away from the tree and start growing. 

So you see all of these tree seeds are specially developed to help it get away from the trees. Especially so that they can grow in a much better environment than the one provided to them initially.
