Answer:
C.
Explanation:
The small population size means that the new colony may have reduced genetic variation from the original population and that variation, in this case, included the dominant allele for Huntington's disease. Genetic drift, along with natural selection, mutation, and migration, is one of the basic mechanisms of evolution. In this case, it was a chance that the settlers all carried the allele for Huntington's disease.
Answer:
The correct answer is 50%.
Explanation:
In the given question, the table says that fruit color is determined by the incomplete dominance of allele R and R'. In the case of RR genotype the fruit color will be red and R'R' the food color will be yellow but in the heterozygous condition the color would be orange, so the cross between RR' and R'R' would be as follow:
Punnett square:
R R'
R' RR' R'R'
R' RR' R'R'
It is found by the given cross that the cross between RR' and R'R' would form two orange fruit plants out of four which is 50%
Answer:
This is a word composed of two roots of Greek origin, the first (deinós), means “terrible” and the second (sauros), means lizard, so dinosaur means literally “giant lizard”. This term was invented in 1841 by Sir Richard Owen and was presented during an annual meeting of the British Association for the Progress of Science. The Dinosauria group originally grouped the three only known dinosaurs: Megalosaurus, Iguanodon and Hylaeosaurus, all from England.
Explanation:
The studies carried out by Richard Owen are so many and so extensive that they are practically unmentionable, however, if we speak of the term dinosaur, the work History of British Fossil Reptiles (History of British reptile fossils), dated 1849 .
In this work Richard Owen talks about the large group of reptiles that exercised total hegemony during the Mesozoic Era and named this group with the term Dinosauria, referring to the biological branching of these prehistoric animals.
The term "dinosaur" and "dinosauria" is mainly because Richard Owen studied three fossils that could not be identified with any other fossil or living animal, such was his astonishment that he decided to name these fossil remains as "terrible lizards."
Hydrolysis is equals to hydro which means water plus lysis which means splitting. Therefore, hydrolysis means splitting/breaking a chemical bond by the addition of water (H2O). More accurately, it is by the introduction of the elements that make up water which are hydrogen and oxygen. Simple example of hydrolysis reaction is an ester is hydrolyzed into an alcohol and a carboxylic acid. Condensation on the other hand is the opposite of hydrolysis. Condensation occurs when two Hydrogen and one Oxygen are LOST from a compound or compounds during the reaction. Most often this occurs when 2 reactants form one product were bond between them being formed by the concerted loss of water (H2O). Condensation example is an alcohol + a carboxylic acid -> ester + H2O.
