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.

10) This is an organism that has two different alleles for the same genetic trait.
KATRIN_1 [288]

Answer:

Heterozygous

Explanation:

An organism in which the two copies of the gene are identical — that is, have the same allele — is called homozygous for that gene. An organism which has two different alleles of the gene is called heterozygous. Pea plants can have red flowers and either be homozygous dominant (red-red), or heterozygous (red-white). If they have white flowers, then they are homozygous recessive (white-white). Carriers are always heterozygous.

A gene cannot react chemically and form a trait without the proper _____. molecule enzyme substrate chromosome
Monica [59]
<span>The word from the pick list that fits here is "enzyme". Enzymes are normally spcialised protein molecules and they act as catalyst ie agents to speed up a reaction in causing traits to develop in the genes of organisms in reaction to chemical stimulants.</span>
