Which is the correct order from smallest to LARGEST?
ss7ja [257]
The answer would be B. Atom, star, galaxy, universe.

Explanation: atoms are small cells that make up everything in existence. They're too small to be seen by the naked human eye. Stars are big balls of gas that can be seen at night in the sky. These are second biggest because you can see these with the naked eye, but galaxies you can not. The galaxy holds the earth, all of the other planets, stars, and other things. If the galaxy can hold all of that then clearly it would be bigger than the stars. The universe is what holds our galaxy. There are millions of other galaxies out there in the universe. Ours is just a small one of an infinite number.

Bacteria can reproduce quickly by means of binary fission. Because of this, after binary fission
Dahasolnce [82]

C) all the offspring will be genetically identical.

Explanation:

During binary fission, all the offspring will be genetically identical and little to no variation occurs.

Binary is an asexual form of reproduction which does not involve the combination of gametes from the parents.

  • During binary fission, the parent simply divides to produce young ones.
  • In this process, the offspring replicates the genetic component of the parents making it identical.
  • The offspring is a direct copy of the parents.
  • It is only in sexual reproduction that genetic materials are exchanged between the parents and offspring. This leads to genetic variation.
