Answer:

2000000 heat calories.

Explanation:

Explanation:

The heat capacity of water is 1 calorie for 1 gram raised 1 degree C

or 4.186 joules of energy for 1 gram raised 1 degree C ( or

K

o

)

l Kg = 1000 grams so

100

1000

g

1

= 100000 grams of water.

It takes 10 000 calories to raise 10 000 grams of water 1 degree

so 20 degrees x 10 000 grams = 2 000 000 calories.

The same type calculations can be done for heat in joules

10, 000 grams x 4.186 joules x 20 degrees. = 8372000 joules.

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.
