By definition, a chaparral ecosystem is mostly located in the south of the United States wherein it mainly comprises the mountain ranges of Sierra Nevada. In addition to that, biotic characteristics of these chaparrals include having abiotic factos such as wet winters and dry summers that sometimes cause wildfires.
Answer:
63 MYA
Explanation:
Morris Goodman was a editor-in-chief of the journal Molecular Phylogenetics and Evolution.
In his classification, every organism was traced back to its last common ancestors, and he traced that of primates last common ancestors to be dated as far back as 63 MYA.
Answer:
Mendel's law of segregation
Explanation:
According to MENDEL Law of segregation, it states that allele pairs that belong to given locus segregate during the process of gamete formation and they will unite at the fertilization stage. Alleles sort out independently because the location of gene is on the specific chromosome.

Answer:
13% cytosine
37% thymine
Explanation:
There are two types of nucleotides based on their structures - purines and pyrimidines.
The purines are adenine and guanine. The pyrimidines are thymine and cytosine.
Chargaff's rule states that the ratio of purines to pyrimidines in a molecule of DNA is 1:1
Therefore, the total number of A+G is the same at the total number of C+T.
All 4 bases together must equal 100% of the DNA molecule
If there is 13% guanine, and guanine always pairs with cytosine, there is also 13% cytosine.Together, that is 26% of the total sample.
100-26 = 74% of the total of adenine and thymine.
Since there are equal amounts of A and T, we know that the DNA sample is 74/2 = 37% thymine
