location Y

Explanation:

The KE of a pendulum bob is maximum where it moves fastest, at the lowest point; PE is maximum at the uppermost points. When the pendulum bob swings by the point that marks half its maximum height, it has half its maximum KE, and its PE is halfway between its minimum and maximum values.

explain how repressible and inducible operons differ and how those differences reflect differences in the pathways they control
Sonja [21]

Answer

Operons are cluster of coordinated genes, including structural genes, an operator gene, and a regulatory gene.

Explanation:

In the The repressible operons, The transcription is usually on and repressor is in inactive form, So the specific genes are transcribed. While a regulatory molecule act as corepressor and binds to repressor protein to activate it. The repressor protein cause the inactivation of repressible operon (as the name indicate). E.g., Tryptophan Repress the trp operon.

A high level of product act as regulatory molecule (Corepressor) and turn off the operon, So anabolic pathways or synthesis of essential components are controlled by repressible operon.

In the Inducible operons, the transcription is usually off and repressor is in active form. So there is no transcription of genes. Specific Metabolite cause the activation of operon  e.g lactose cause the induction of lac operon.

As a metabolite induces the operon, So they control the Metabolic pathways or breakdown of a neutrient.

The question tells you that the rock forms when it is cooled by the water, so you know it is formed outside of the Earth's interior, therefore making it extrusive igneous rock. </span>

What is the term for the breakdown of organic sediment into inorganic phosphorous?
Alchen [17]

This might refer to the phosphorus cycle.

Phosphorus cycle is a biogeochemical cycle that observes how phosphorus move through minerals, soil, water, and organisms. Typically, plants absorb phosphorus from the soil. And animals get phosphorus from the eaten plants. When these organisms dies, they decay and the phosphorus returns to the soil and inorganic matter.
