<span>The scientific view's order of Earth's first living things to the most recent is described by choice C. cyanobacteria, hagfish, crocodilians, giant ground sloths. Cyanobacteria have lived on the Earth since the Precambrian supereon. Actually, they first appeared in the Archean eon (4-2.5 billion years ago). Hagfish, as other jawless fish, appeared in the Paleozoic era (541-252 million years ago). Crocodilians appeared in the Cretaceous period (145-66 million years ago). Giant ground sloths, also known as megatherium, appeared in the Pliocene epoch (5.33-2.58 million years ago).</span>
If the uppercase letters represent the dominant alleles, purple flowers and tall are the phenotype of a plant with the genotype Pptt.
A gene can exist in different forms across organisms. These different forms are known as alleles.
The subsequent combination of alleles that an individual possesses for a specific gene is their genotype.
Examples of genotype include:
- Hair colour
- Height
- Shoe size
- Eye colour
The sum of an organism’s observable characteristics is their phenotype. A key difference between phenotype and genotype is that, whilst genotype is inherited from an organism’s parents, the phenotype is not.
Whilst a phenotype is influenced the genotype, genotype does not equal phenotype. The phenotype is influenced by the genotype and factors including:
- Epigenetic modifications
- Environmental and lifestyle factors
Observing the phenotype is simple – we take a look at an organism’s outward features and characteristics, and form conclusions about them. Observing the genotype, however, is a little more complex.
Genotyping is the process by which differences in the genotype of an individual are analyzed using biological assays. The data obtained can then be compared against either a second individual’s sequence, or a database of sequences.

Answer:
Cockroach is you answer.
Explanation:
They do this by using a very efficient breathing system that uses air filled tubes, called trachea, to deliver oxygen directly to cells. Oxygen flows in as required into the tracheal system through valves on the insect, called spiracles. But, sometimes, they shut their spiracles and stop breathing.
The average is 3.4 minutes
