The geologic time scale is referred to as the system of chronological dating which is related to geological strata to time. It is used by palaeontologists, geologists and earth scientists to describe the relationship of events and timing that occurs during Earth’s history. The primary division of time is defined as eons. Eons follow a sequence of the Archean, the Hadean and the Proterozoic which are referred as Precambrian superon.
Eons are divided into an era whereby those eras are subdivided into periods, ages, and epochs. Eon, epoch, period and ages correspond with eonothem, series, systems and stage which are mostly used to refer to layers of rock which then stretches to geologic time in the history of the earth.
Answer:
Photosynthesis
Explanation:
Because photosynthesis need CO2 to work, but for cellular respiration CO2 is a waste, so it is <em>contributing </em>to the higher amounts of CO2 but it does not affect it
Answer:
A. 4 right handed coil:0, left- handed coil
Explanation:
According to MENDELION CROSS:
We will get NN, Nn,Nn,nn
NN, Nn, Nn are the 3 right handed coiling and nn is left handed coiling.
But in case of shell coiling in snails, maternal inheritance is applied in which offspring is decided only by phenotype.
Maternal traits: Here,female parent has right handed shell coiling. so, all the offsprings will have the same.
Hence, the phenotypic ratio will be:
4 Right handed coil: 0 Left handed coil
