Earth was formed over 4.5 billion years ago meaning this world looked completly different from how it looks now. volcanic outgassing most likely created the world (but it's still uncertain). the earth began in the ocean and arose from there. the early atmosphere contained almost no oxygen until later in the years, building up oxygen. The earth contained a diveristy in chemicals.
hope this helps!!
The probability of producing plants with white axial flowers is 1/16.
The given question is based on the law of independent assortment.There are two parents out of which one has red, axial flowers (RY) and the other one has white, terminal flowers (ry).
In F1 generation, all individuals have red, axial flowers which is RrYy which results in the formation of 8 gametes which is 4 from each parent. When these gametes are crossed with each other individually using a punett square, it results in the formation of 16 offspring out of which only one offspring has white terminal flowers.
Thus, the probability of producing plants with white axial flowers is 1/16.

The telephone is one of the most important inventions made by man as it allowed communication to speed up through time.
Answer:
Polymerase chain reaction machine
Primers
Petri dishes
Test tubes
Pipettes
DNA Polymerase
Free nucleotides
The organism to be identified
Explanation:
To identify the genetic makeup of an unknown organism, the nucleotide sequences fond in the Deoxyribonucleotide (DNA) of a known organism is matched to the DNA of some known organisms. If there is a certain degree of sameness in most of the matched parts, then the unknown organism can be said to be related to the known organism. This is a comparative study.
To carry out this identification, items used include; primers, the PCR machine, test tubes, DNA polymerase, free nucleotides, etc.
