Answer:

collapse, condensation and accretion

Explanation:

According to the nebula hypothesis all the bodies in our solar system began as a giant cloud of molecular gas and dust, something happened about 4.57 billion years ago which caused the cloud to collapse (collapse).  

  After the collapse pockets of dust and gas came together to form denser regions (condensation). this denser regions pulled in more matter and conservation of momentum caused it to begin rotating and then heating up due to increasing pressure. Most of the material ended up in a ball around the center which and the rest of the matter flatten out into disk (protoplanetary disc) around it (accretion).

Answer:

TATTCATTCATTA—TGATTT—ATTCG

Explanation:

A mutation is a permanent change in the nucleotide sequence of DNA. A mutation occurs during replication or recombination. It may be due to base substitutions, deletions and insertions. As per the question, DNA segment forms encodes for the enzyme pepsin is CATTGTTA.

Option TATTCATTCATTA—TGATTT—ATTCG is the correct answer. In the DNA segment which encodes pepsin, a purine base (G) guanine is replaced by another purine (A) adenine. This type of mutation is called a transition type point mutation.

Due to base substitution, the mutated segment CATTCATTA will nor encode pepsin.

Which of the following statements describes a battery?
LiRa [457]

Answer:

The negative electrode of a battery has an excess of positive charge

Explanation:

This is because in every battery, there is a negative electrode ( cathode ) and only positive charge is deposited on it.

For other statements:

Batteries donot store electric charge but they store chemical energy

Some batteries donot use metals for the flow of electrons, but some use hydrogen gas at a pressure of 1 atmosphere.
