Two species of tree frogs that live sympatrically in the northeastern United States differ in ploidy: Hyla chrysoscelis is diplo

id, and Hyla versicolor is tetraploid. The frogs are identical in appearance, but their mating calls, which females use to find mates, differ. Which difference most likely evolved first? (A) polyploidy (B) difference in mating calls (C) habitat differentiation (D) Polyploidy and different mating calls must have evolved at the same time.

The correct answer is B (difference in mating calls).

Species

A species is the basic unit of classification and taxonomic rank of an organism, as well as a unit of biodiversity, in biology. A species is typically defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, most commonly through sexual reproduction. Species can also be defined by their karyotype, DNA sequence, appearance, behavior, or ecological niche. In addition, because fossil reproduction cannot be investigated, palaeontologists use the concept of chronospecies.

Describe the relationships among amino acids, chromosomes, proteins, and genes in the cells of a jackalberry plant. Make sure to
nasty-shy [4]

Answer:

The jackalberry plant is a multicellular organism whose cells contain chromosomes. The chromosomes contain genes that are transcribed to produce messenger RNAs, which are then translated into proteins  

Explanation:

The Jackalberry tree is a plant, i.e., a multicellular organism. Multicellular organisms have chromosomes in the nucleus of each cell. A chromosome is a long DNA molecule that contains part (or even all) of the genetic information of a particular organism. Genes are specific segments of the chromosomes, which are expressed in a process called 'transcription' where a gene is used as template to synthesize an RNA molecule, usually a messenger RNA (mRNA). Subsequently, these mRNAs are used to synthesize proteins by a process called 'translation'. In an mRNA molecule, each specific triplet of nucleotides is known as a codon and corresponds with a specific amino acid during protein synthesis. Thus, the mRNA sequence dictates the correct order of amino acids (i.e., the building blocks of proteins) in the polypeptide chain.
