Answer:
a. Documenting species
Explanation:
first half of the century, time in which primarly scientists the discovery of the depth and size of the ocean.
The velocity of the object is similar to speed but has one main difference: velocity takes into account the direction of an object. Since speed does not take direction into consideration, it is considered to be a scalar quantity. Thus, the speed of an object can never be negative.
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.
The correct answer is- Beneficial
It is during the phase cytokinesis that the cell membrane separates the cell into two.
