Answer:
Evidence for evolution comes from many different areas of biology:
Anatomy. Species may share similar physical features because the feature was present in a common ancestor (homologous structures).
Molecular biology. DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are.
Biogeography. The global distribution of organisms and the unique features of island species reflect evolution and geological change.
Fossils. Fossils document the existence of now-extinct past species that are related to present-day species.
Direct observation. We can directly observe small-scale evolution in organisms with short lifecycles (e.g., pesticide-resistant insects).
Answer:
4 quaters and 2 quaters make up 50 cents then with the dimes you should have 5 dimes making it also 50 which also equals a dollar leaving you with 2 dollars
Explanation:
;)
Answer:
The most appropriate answer would be "evidence of changing environmental conditions, with references".
As Mr. Potts claimed that great variations in environmental conditions over time were responsible for the adaptability of humans and the success of our species in his paper, he must have mentioned evidence of changing environmental conditions with references.
In addition, he must have shown the effects of changing environmental conditions on the adaptations made by human species due to those changes.
Answer:
9:3:3:1
Explanation:
The ratio that result in dihybrid inheritance can be presented in the form of probability for two heterozygous traits in an organism. For example, during mendel's experiment using heterozygous tall pea plants and heterozygous purple flower,Both parents are heterozygous, and therefore one allele for each trait shows complete dominance. This simply indicates that both parents have recessive alleles, but express the dominant phenotype. The phenotype ratio predicted for dihybrid cross is 9:3:3:1( TT PP: Tt Pp: tt pp)
Nine combinations express offspring with both dominant phenotypes. Three combinations each producing offspring with one dominant and one recessive phenotype therefore the offsprings being heterozygous for the trait. One combination produces a complete recessive offspring.
