Answer:

airlines - Testable

pollutants- Testable

chocolate- Testable

meat- Nontestable

Explanation:

The situation or questions can be testable only when an experiment can be performed to find the result or answer to the question. One variable is changing one thing to see the effect on another thing. These are known as testable experiments.

The nontestables are questions that cannot be answered by performing experiments. These questions have skeptical answers.

Scientists have genetically engineered potato plants to produce potatoes that contain edible vaccines. Which is a disadvantage o

Valentin [98]

Answer:

They are more expensive than potatoes without the vaccine.

The genetically modified crops are produced by using the scientific procedures of genetic engineering. It involves the manipulation of the genome of these crops so as to make them disease resistant, improving the quality of the edible parts and increasing the yield of the plants. The crops are genetically modified with accuracy, precision and implementation of the technology therefore, the crops produced are expensive then the crops produce by the conventional method.

Hence, they are more expensive than potatoes without the vaccine is a disadvantage of the genetically engineered potato plants to produce potatoes that contain edible vaccines.

vivado [14]

I have attached lac operon model having 4 genes. See attachment for better understanding.

Answer:

The Lac operon is controlled by two signals.

Initiation

Glucose and lactose concentrations control the initiation of transcription of the Lac operon through their effects on the Lac repressor protein and Cap.

Lactose absent (Repression)

When lactose is absent, the Lac repressor binds the Lac operator and shuts off expression of the operon.

Lactose present (Transcription)

Addition of lactose increases the intracellular concentration of a related compound, allolactose. allolactose binds to the Lac repressor, causing it to undergo a conformational change that releases its grip on the operator DNa.

Glucose absent (Repression)

When glucose is absent, cyclic aMp (red triangle) is produced by the cell and Cap binds to DNA.

Glucose present (Transcription)

LacZ, the first gene of the operon, encodes the enzyme b-galactosidase, which breaks down lactose to galactose and glucose.

Lostsunrise [7]

Answer:

11) Weather changes from day to day, while climate changes from region to region.

12) Using the image here, we can trace the interaction of Earth's spheres. Plants (biosphere) draw water (hydrosphere) and nutrients from the soil (geosphere) and release water vapor into the atmosphere.

Hope this helps. :)
