Explain the Microsphere theory of sydney fox.

Answer»

NYC Question❣️❣️❣️

╔════════════════╗

...HERE G⓪ES Y0UR ANS...

╚════════════════╝

<U>According to Dr. Sidney W. Fox

  • The origin of the cell is a Microsphere or protocell.
  • Microspheres are made from the addition of water or salt solution to the appropriate proteinoids.
  • One gram of PROTEIN polymer yields up to one billion microspheres with about ten billion molecules of proteinoid in each sphere.
  • Fox says that the assembly of microspheres takes about twenty minutes and is more immediate and produces better microspheres if the water (or salt solution) is heated prior to mixing.
  • Microspheres have multiple properties that are similar to those of cells. The microspheres produced were mostly uniformly spherical and Fox believed that the shape and uniformity mimics that of coccoid bacteria.
  • He also believed that the uniformity MEANT that there was a SOPHISTICATED system that kept the microspheres at equilibrium.
  • The microspheres were able to asexually divide via binary fission, could form junctions with other microspheres, and developed a double membrane corresponding to that of a cell.

How do neural networks interpret words, and human language?

NYC Question❣️❣️❣️

╔════════════════╗

...HERE G⓪ES Y0UR ANS...

╚════════════════╝

The basic idea behind a neural network is to simulate lots of densely interconnected brain CELLS inside a computer so you can get it to LEARN things, recognize patterns, and make decisions in a human like way.

Information flows through a neural network in two WAYS. When it's learning or operating normally patterns of information are fed into the network via the input units, which trigger the layers of hidden units, and these in turn arrive at the output units.

This common design is called a FEED forward network. Each unit RECEIVES inputs from the units to its left, and the inputs are multiplied by the weights of the connections they travel along.

Every unit adds up all the inputs it receives in this way and if the sum is more than a certain threshold value, the unit "fires" and triggers the units it's connected to.

Answer»

Petroleum is a mixture of several hydrocarbons. It also contains WATER salt and Rocky MATERIALS which cannot be used in this crude from either as a fuel or basic material to produce other useful components. Before put to use, it has to purified or refined. The process of separating the various components of petroleum from one another is known as the REFINING of petroleum. This is done by a process called fractional distillation which is BASED on the fact that the different components of petroleum have distinctly different boiling points.

In fractional distillation, crude petroleum is heated to a temperature of 400°C or slightly above in a furnace.

Uses of petroleum

1. Petroleum products are used as fuels.

2. Lubricating oils and Vaseline are used as lubricants.

3.Paraffin wax products of petroleum is used for manufacturing candles polishes waxedpaper waterproofing etc.

WHAT IS CONTRIBUTARY CAUSES.CHAPTER - WHY DO WE FALL ILL.CLASS - 9thSUBJECT - BIOLOGY

Answer»

Hi.
GOOD morning dear,

I'm also same class

Contributory cause is a clinically useful concept of causation. It requires demonstration that (1) the presumed cause precedes the effect and (2) altering the cause alters the effect. It does not require that all those who POSSESS the contributory cause experience the effect. It does not require that all those who are free of the contributory cause be free of the effect. In other words, a CLINICAL cause may be neither necessary or sufficient but it MUST be contributory.
