Answer:

Below!

Explanation:

Currently the best theory is <u>the Nebular Theory. </u>This states that the solar system developed out of an interstellar cloud of dust and gas, called a <u>nebula. </u>This theory best accounts for the objects we currently find in the Solar System and the distribution of these objects. <u>The Nebular Theory </u>would have started with a cloud of gas and dust, most likely left over from a previous supernova. The <u>nebula</u> started to collapse and condense; this collapsing process continued for some time. The Sun-to-be collected most of the mass in the nebula’s center, forming a <u>Protostar.</u>

A <u>protostar</u> is an object in which no nuclear fusion has occurred, unlike a star that is undergoing nuclear fusion. A <u>protostar</u> becomes a star when nuclear fusion begins. Most likely the next step was that the nebula flattened into a disk called the Protoplanetary Disk; planets eventually formed from and in this disk.

Three processes occurred with the nebular collapse:

  • Temperatures continued to increase
  • The solar nebula spun faster and faster
  • The solar nebula disk flattened

The orderly motions of the solar system today are a direct result of the solar system’s beginnings in a spinning, flattened cloud of gas and dust.

Hoped this helped.

Students hypothesized that adding lactose to a sixth test tube would produce the greatest amount of carbon dioxide.

This is because lactose is a sugar molecule that is the food source for the yeast.

Fermentation is a metabolic pathway that occurs anaerobically, meaning in the absence of oxygen (O2). It includes the process of glycolysis with some extra reactions which make alcohol.

The blockage of cerebrospinal fluid (csf) outflow in the brain can cause accumulation of fluid, resulting in cranial enlargement
alisha [4.7K]

The correct answer is hydrocephalus.

Hydrocephalus refers to the condition in which the accumulation of fluid takes place in the ventricles (cavities) deep inside the brain. The excess fluid enhances the size of the ventricles and applies pressure on the brain. The cerebrospinal fluid usually flows via the ventricles and bathes the spinal column and the brain.
