PCR multiplies the DNA in 25 to 75 cycles
Neko [114]3 years ago
6 0
This is the chain reaction in the name polymerase chain reaction. PCR is so efficient because it multiplies the DNA exponentially for each of the 25 to 75 cycles. A cycle takes only a minute or so and each new segment of DNA that is made can serve as a template for new ones.

at over 5 million degrees celsius the temperature of the sun core is high enough for nuclear to occur
Paraphin [41]

Answer:

Yes (but not how you think)

Explanation:

I'm assuming that you mean if nuclear fusion, where two atoms (in this case mostly hydrogen) fuse into one heavier atom, and release a lot of energy.

However, fusion happens when there is a tremendous amount of pressure or heat. This is found in the core

The 5 million degrees is found on the surface of the sun, but at the core, it is at 15 million degrees.

In addition, the pressure is so extreme that if forces atoms to become one, despite the fact they don't like being together (try finding 2 strong magnets and hold them so that they try to repel each other and try and make them touch, it's hard! Now imagine having to put a million of times the amount of strength!)

So, the sun is capable of nuclear fusion, but at the core, where it is 15 million degrees!

(fun fact: scientists are trying to build "mini-suns" called Fusion reactors to try and harvest the power of the sun!)

_____ are sessile animals that have specialized cells called amoebocytes and choanocytes.
Artemon [7]

Sponges are sessile animals that have specialized cells called amoebocytes and choanocytes.

Sponges (phylum Porifera) are one of the simpllest multicellular organisms (first to branch off the evolutionary tree from the common ancestor of all animals) that have bodies full of pores and channels allowing water to circulate through them. Sponges’ s structure consists of two thin layers of cells and mesohyl layer between them. They don’ t have real tissues or organ systems such as nervous, digestive or circulatory systems. Constant water flow through their openings and pores obtain food and oxygen and remove wastes.
