How are supernovae involved in new planet formation?

Biology
1 answer:
Lisa [10]3 years ago
3 0
Supernovae refer to the last stages in a star's life, when it explodes and disappears completely. After this explosion, there are several things that can happen - a black hole may appear or there may be star dust hovering in the universe. Well, this dust, and other materials that came from the massive star that exploded are used to create new planets. Every planet we know of emerged from the dust and particles in the universe - so this means that the same dust coming from supernovae can form new planets as well.

That is the opbposite of synthesois reaction
yaroslaw [1]

The two basic reaction types are synthesis and decomposition. ... Decomposition reactions are the opposite of synthesis reactions because they take apart larger molecules and/or compounds. The generic equation for a synthesis reaction is A + B à AB, where A and B are the pieces that make up the compound/molecule AB.

Describe the role of decomposers in the rainforest ecosystem
Harrizon [31]
Just as they do in most ecosystems, decomposers feed off of dead or decaying matter, recycling it back into the ecosystem for plants to receive essential nutrients and to.. basically, de-clutter the world.

Why is the sympathetic division of the ans called the "fight or flight" system?
Assoli18 [71]
The fight or flight system is a reaction that the body undergoes when put in an either stressful or frightening situation. It includes both the nervous and endocrine system. 

The sympathetic division of the peripheral nervous system is used in this response as the sympathetic nervous system works up the body, increases the rate of breathing, heart rate, dilates the pupils, produce more sweat and slow the digestion rate. This reaction happens in the flight or fight system.

The purple spots on colorless background of corn kernels observed by barbara mcclintock were the result of _______.
vitfil [10]

The purple spots on the colorless background of corn kernels observed by Barbara McClintock were the result of the transposition of the Ds elements out of the color gene.

<h3>What are the genetic elements found in corn?</h3>
  • A transposable element is removed from one spot in the DNA and inserted into a different site in the DNA during the process of genetic transposition, which allows genes to shift their location on chromosomes.
  • The first recognized genetic instability was caused by genetic transposition.
  • The size of the tissue patch displaying the reversion phenotype increases as a reversion event happens earlier in the kernel development.
  • Barbara McClintock saw purple dots on maize kernels with an otherwise colorless background.
  • These spots were caused by the Ds components of the color gene being transposed.
  • The wild-type (purple) phenotype manifests itself in cells where Ds from the color gene "C" sequence has been lost.

Hence, Barbara McClintock discovered purple patches on the colorless backdrop of maize kernels due to the transposition of the Ds elements out of the color gene.
