Complete question:
Members of the tropical tree genus Ceiba currently grow in the rainforests of the Amazon. A paleontologist discovers several fossils that she attributes to this genus in the Pampas region of Argentina. This region is not currently covered with tropical rainforests. She concludes based on these fossils that this region of Argentina was covered with tropical rainforests in the past. This form of reasoning is known as:
A.
Deduction.
B.
Induction.
C.
Abduction.
D.
A random guess.
Answer:
This form of reasoning is known as Deduction (Option A)
Explanation:
Induction: Might be defined as a process of initiation in something, such as a religion, a new job, a new activity, a new curse, etc.
Abduction: Refers to the illegal act of taking someone somewhere by obligation or by force, against the person´s will. Also refers to the body´s extremities movement.
A random guess: Refers to a random conjecture about something, with no basis or fundaments.
Deduction: The fact of answering a question or reaching a conclusion based on evidence or fundaments. Usually after a process of investigation or study, and knowing the facts.
The exposed situation is an example of a deduction made by the researcher. She bases her conclusion on the fact that Pampa´s fossils might be of the same genus as Amazonia´s trees, which means that in Argentina the environmental and climatic conditions were comparable to those in current Amazonia. Also, as a paleontologist, she must know about the biogeographic processes that modeled the earth and living beings. Her conclusions are not random. She has bases and fundaments to conclude that Argentina was once covered with tropical rainforests in the past.
C. In radiometric dating, scientists place samples of a fossil in certain liquids until the samples dissolve. The rate at which they dissolve indicates the age of the fossil.
Answer:
bright blue trait = recessive
yellow trait = dominant
Explanation:
let the letter B represent the gene for skin colour.
This means that the dominant gene is 'B' while the recessive gene is 'b'
A dominant gene is one that is exhibited phenotypically in the presence of both gene variants (heter0zygous state - Bb) while a recessive gene is only expressed phenotypically when it is in a h0m0zygous state (bb)
In order to find out the genotype of the parents, let us consider each cross one after the other.
1. A bright blue female and a bright blue male produce all blue progeny.
2. A yellow female and a yellow male produce a mix of both bright blue and yellow progeny
From statement 2, it can be deduced that the trait for yellow colour is dominant because a cross of the parents exhibiting this trait produces bright blue offsprings too, meaning that the genetic composition of the parents contains the gene that codes for yellow colour. Since these parents show a yellow colour in a heterozygous state, then the trait for yellow colour is dominant.
Therefore, the genotypes of the parents in each case include:
1. A bright blue female and a bright blue male produce all blue progeny. (bb × bb)
2. A yellow female and a yellow male produce a mix of both bright blue and yellow progeny (Bb × Bb)
