<u>Answer:</u>
The scientists have used the common historical and functional basis of living organisms to create the geological time period.
<u>Explanation:</u>
All the living things present on earth have gone through the evolutionary process. According to the researches, the oldest fossil found on the earth can be traced 3.5 to 3.7 billion years back, and life today on earth has been evolved from a common ancestor through natural selection or adaptions.
The geological time period shows all the changes in living organisms in different eras eons, eras, periods, epochs.
Answer:
0,58
Explanation:
Mice are diploid (2n) organisms, which means that their cells contain two complete sets of homo-logous chromosomes (i.e., they have two copies of any given <em>locus</em>/gene). An allele can be defined as a variant of a gene, whereas diploid (2n) organisms have two alleles at each genetic <em>locus</em>, which are located on homo-logous chromosomes. In this case, we know that there are 580 dominant alleles in a population of 500 individuals, thereby the total number of alleles in this population is 1000 (2n >> 500 x 2 = 1000 alleles), and the frequency of the dominant allele is 0,58 (580/1000 = 0,58).
Answer:
C. under 1 and 2. because Earth's entire outer layer is made of hard, solid rock
Explanation:
Just because 2 is under water does not mean it will not work it will just be very difficult. But at the bottom of the sea there is always solid rock.
So, the population went up with every spring season and fell slightly in the winter; it increased within the course of 10 years
The color of a star is primarily determined by its surface temperature.
For example, the really hot stars, called White Dwarf stars, have a white surface temperature, while a cooler star would have a more red color.
