Suppose humans accidentally introduced a non-native species to a can of warriors bird to the region if these birds feeder school
jekas [21]
This would negatively impact the native bird species and the fish population as well as any other underwater species such as smaller fish and algae as they may have overgrowth and could even become an invasive native species over time because the food chain would be disrupted. The native bird species wouldn’t have much food supply and would either die off or migrate to another place, and the feeder schools of fish (large fish) would probably also eventually die off because they would be over dominated with multiple species feeding off of them. The natural food chain already established would be disrupted.

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.

Paul, sean, and mike have each consumed four beers in the last two hours. paul weighs 220 pounds, sean weighs 165 pounds, and mi
Goshia [24]
Sean, who weighs the least of the three, will have the highest blood alcohol concentration (BAC).

The less a person weighs, the more they will be affected by a given amount of alcohol. People of the same weight, even the same gender, individuals with a lower percentage of body fat will have lower blood alcohol concentration than those with a higher percentage of body fat.

Hope this helps! :)
