Adenine binds to? - CORRECT ANSWER✅✅Thymine
Which vertebrates are capable of digesting cellulose? - CORRECT ANSWER✅✅None
How is an antinutrient a defense mechanism of plants? - CORRECT ANSWER✅✅A compound produced
by the plant that limits the absorption of certain nutrients by the animal
Cytosine binds to? - CORRECT ANSWER✅✅Guanine
Heritability - CORRECT ANSWER✅✅the proportion of phenotypic variation in a population due to the
genetic variation of a population
Pleiotropy is the phenomenon in which - CORRECT ANSWER✅✅one gene affects two seemingly
unrelated traits
A significant proportion of nutrient absorption occurs in the - CORRECT ANSWER✅✅Small intestine
Essential fatty acids are also known as - CORRECT ANSWER✅✅omega fatty acids
Which industry is greater in production? Beef or Dairy? - CORRECT ANSWER✅✅Dairy
Horses have a simple stomach (like humans) but are capable of digesting plant material (like cows).
Why? - CORRECT ANSWER✅✅Horses have a large, highly developed cecum in which plant matter is
digested before continuing through the large intestine
A female cow that has not yet given birth is called a - CORRECT ANSWER✅✅Heifer
, accurace of selection - CORRECT ANSWER✅✅how well the estimate represents the true breeding value
Was Dolly the sheep the first transgenic animal ever created? - CORRECT ANSWER✅✅Nope
Benefits of understanding animal behavior are: - CORRECT ANSWER✅✅- The ability to anticipate an
animal's reaction to a stimulus
- The ability to differentiate between a normal and abnormal behavior
Chromosomes come in pairs, one from the mother and one from the father. These paired chromosomes
are referred to as - CORRECT ANSWER✅✅homologous
Alleles - CORRECT ANSWER✅✅- are the various forms of a given gene on corresponding homologous
chromosomes
- for a particular gene affect the same the trait
- are generally represented by a letter
selection differential - CORRECT ANSWER✅✅how much superior the selected animals are compared to
the non-selected animals
Alpha-helices and beta pleated sheets are - CORRECT ANSWER✅✅secondary structures of proteins and
are formed due to hydrogen bonding of the peptide backbone
Habituation - CORRECT ANSWER✅✅When an animal learns to ignore a stimulus that occurs often
selected intensity - CORRECT ANSWER✅✅the proportion of superior animals are selected as
replacements
Phenotype formula - CORRECT ANSWER✅✅Phenotype = genotype + environment
