Answer: Homologous structures
Explanation: They are structures which have similarities in various organisms but carry out opposite functions. This is the opposite of analogous structures
The right answer is The lac operon would be transcribed constitutively.
An operator is a nucleic acid segment to which a regulatory protein that modulates downstream gene expression is bound. it can either stimulate or inhibit the production of the gene product thus controlled.
If the operator is absent, there will be no more regulation of the operon, so the transcription of the operon will not be regulated, and the synthesis will be continuous and constitutive.
D, increase population of all species, because humans have not helped increase the population of ALL species. In fact, humans are at fault for the decline of some species.
Pea plants have 2 different variations for their genes. Ex: All of the offspring get Y for yellow plant and y for the green plant so they are all Yy. Yy is a yellow plant. yy is a green plant because of gene variations
