Jacob and Monod were intellectually primed to draw the conclusions they did concerning regulation of the lac operon. In part, th

is was due to their fascination with mechanisms of enzyme regulation. They knew that the activity of some enzymes is regulated when their reaction product binds to the enzyme, changing its shape and therefore its activity. This knowledge allowed them to easily make the intellectual leap to propose _____.A) the existence of the CAP binding siteB) allosteric regulation of the repressorC) positive regulation of the lac operonD) the existence of the operatorE) co-transcribed and co-regulated genes of bacterial operons

Answer:

Jacob and Monod were intellectually primed to draw the conclusions they did concerning regulation of the lac operon. In part, this was due to their fascination with mechanisms of enzyme regulation. They knew that the activity of some enzymes is regulated when their reaction product binds to the enzyme, changing its shape and therefore its activity. This knowledge allowed them to easily make the intellectual leap to propose B) allosteric regulation of the repressor

Explanation:

When we talk about the mechanisms of enzyme regulation, we refer to allosteric regulation of the repressor. The Allosteric control of transcriptional regulatory proteins allows organisms to react to changes in environmental and metabolic conditions. Also, it is s a thermodynamic phenomenon. When it binds one molecule, the affinity with which a protein binds to a second molecule is altered.

How is a land breeze similar to a sea breeze? How do the differ?
Pavel [41]
<span>Sea breezes and land breezes are similar in that they are both created by changes in temperature near the ground. With a sea breeze, the air over land warms (during daytime), pressure drops, and air accelerates from sea to land in response. With a land breeze, the air over land cools (during nighttime), pressure rises, and air accelerates from land to sea in response.</span>

How does predation alter a population’s gene pool?
Phoenix [80]

Answer:

Option C

Explanation:

If we consider Darwin's theory we would realize that the species which are not able to survive are unfit or weak. Thus, predators usually attack species that can be easily targeted. Hence, it this way predation leads to selective pressure on any species and hence leads to creation of a fit gene pool. The weak organisms are removed and more fit organism could mate among themselves to produce healthy offspring.  

 Hence, option C is correct

What is represented by<br> region on the sound<br> wave
elena-s [515]

Answer:

Compressions and Rarefactions

<em>A vibrating tuning fork is capable of creating such a longitudinal wave. As the tines of the fork vibrate back and forth, they push on neighboring air particles. The forward motion of a tine pushes air molecules horizontally to the right and the backward retraction of the tine creates a low-pressure area allowing the air particles to move back to the left.</em>

Explanation:

These regions are known as compressions and rarefactions respectively. The compressions are regions of high air presure while the rarefactions are regions of low air pressure.

<em>Sound waves can also be shown in a standard x vs y graph, as shown here. This allows us to visualise and work with waves from a mathematical point of view. The resulting curves are known as the "waveform" (i.e. the form of the wave.) The wave shown here represents a constant tone at a set frequency.</em>
