Under which conditions are the lac structural genes expressed most efficiently?
madam [21]

Lac genes are most effectively expressed in presence of Lactose and its analogs when glucose is absent.

Explanation:

A unit of prokaryotic gene expression and regulation,which includes structural genes and regulatory sequences recognized by regulatory gene product is called operon.

<em>Lac </em>structural genes are a part of<em> Lac</em> operon. The <em>Lac </em>operon consists of three, structural genes,an operator and a promoter.The product of Lac operon is involved in the conversion of disaccharide lactose into glucose and Galactose.

Lactose and its analogs are inducers of<em> Lac </em>operon. So, the structural genes are best expressed in presence of Lactose. Glucose and galactose are repressors of lac gene so the genes are repressed in presence of glucose.

biologists is studying two species of lizards in a mountainous region. The two species are separated by habitat with one species
ivann1987 [24]

Answer:

Valley lizard = Oviparous

Mountain lizard = Viviparous

Explanation:

In Darwin's theory survival of the fittest, he believed species adapt or change within their environment. So I believe lizards living in a valley would be more safe to lay their eggs but lizards living in the mountains would be viviparous because of the non-predicted and unsafe environment which could harm the better chances of development of the offspring.
