Answer:
The tendency of the bird or the inclination to sing is innate in birds, however, the song, which is sung is learned. There exists an innate tendency to sing a song whether the bird is in seclusion or not. The birds possess sensitive/critical periods when they can produce memories of the songs they learn. The anterior forebrain pathway or the anterior vocal pathway is the template for learning a song by the bird.
Answer: Symbiosis and Parasitism
Explanation: Two organisms can be in a mutual relationship (symbiotic) and benefit from each other or one lives in the body of another and benefits from it, while the host organism suffers.
Answer:
No
Explanation:
Lactose intolerance only affects your ability to break down lactose.
Answer;
-are mirror images of one another.
Thalidomide and l-dopa, shown below, are examples of pharmaceutical drugs that occur as enantiomers, or molecules that are mirror images of one another
Explanation;
-Enantiomers are chiral molecules that are mirror images of one another. Furthermore, the molecules are non-superimposable on one another. This means that the molecules cannot be placed on top of one another and give the same molecule. Chiral molecules with one or more stereocenters can be enantiomers.
Enantiomers have identical chemical and physical properties in an achiral environment. They rotate the direction of plane polarized light to equal, but opposite angles and interact with other chiral molecules differently.
Answer:
<u>the bottleneck effect</u>
<u />
Explanation:
Genetic drift has an important impact on the small populations. mutations, which are spontaneous heritable changes in the genetic code, made up of DNA. Here, mutations accumulate over time in a group, modifying the distribution of alleles or various forms of a gene. Natural selection may result in a loss of diversity in a population called genetic drift; one trait's allelic frequency rises while others become less prevalent. Typically such differences exist because of occurrences of mutation and recombination.
Some mutations or alleles may become extinct from the population.
<u />
Variants of a gene accumulate and are transmitted across generations; the frequencies of these occurrences are altered and become more stable in genetic drift- they become genetically distinct and may eventually form a new species after isolation. This may be further compounded through other phenomena such as the founder effect where a group separates and genetic diversity decreases; and the bottleneck effect where barriers to reproduction or the die-off a population increases genetic drift.
