docker41 [41]3 years ago
3 0

Answer: Volcanic materials ultimately break down and weather to form some of the most fertile soils on Earth, cultivation of which has produced abundant food and fostered civilizations. The internal heat associated with young volcanic systems has been harnessed to produce geothermal energy

Which phrases describe radioactive elements? Check all that apply.
svp [43]

A radioactive element is an element which is subject to spontaneous degeneration of its nucleus followed by the emission of alpha, beta and gamma particles. All elements with atomic numbers greater than 83 are radioactive.

The given phrases that describe radioactive elements are-

They have a consistent number of particles - the particles are alpha, beta and gamma particles.

They have a half-life that determines their rate of decay.

Explanation for other options:

Not all elements occur in nature. Radioactive decay rates may not be constant as the decay happens when a radioactive substance emits a particle. It is not possible to predict exactly when a given atom of a substance will emit a particular particle. When the radioactive element release energy and particles, it decays.

Some homeostatic imbalances cause a variable that is normally controlled by negative feedback to be abnormally controlled by pos
tigry1 [53]

Answer:

True

Explanation:

Some deviations from normal homeostasis activate the positive feedback loops to control the conditions which are otherwise regulated by negative feedback mechanisms.

For example, the blood levels of respiratory gases and H+ ions are regulated by a negative feedback system via chemoreceptors. The increased partial pressure of carbon dioxide gas and lowered pH or lowered partial pressure of oxygen in the blood are sense by central and peripheral chemoreceptors which in turn activate the neurons of the dorsal respiratory group (DRG).

The activated DRG triggers an increased in the rate and depth of the breathing to facilitate the inhalation of more oxygen and exhalation of CO2 to restore the normal levels.  

However, hypocapnia inactivates the chemoreceptors and does not allow negative feedback to restore the normal CO2 levels in the blood.  

Under such conditions, the positive feedback loop stimulates the DRG neurons more strongly in response to the increased partial pressure of CO2 above the normal levels than when the partial pressure of oxygen falls below the normal level. These dangerously lowered oxygen levels may also cause fainting.

 3. Compare the amount of energy that can be stored in ATP and glucose. How does the cell use each of these molecules to store
bogdanovich [222]
<span>3. Cells use glucose to store large amounts of energy for long period of time. 
In contrast, ATP is used to </span>store smaller amounts of energy that will be used in the next few seconds.<span>
A glucose molecule can store more than 90 times the energy of a ATP molecules.

4. The fact that the potted plant is in air tight jar affect the process of photosynthesis. The plant is airtight jar which means that the plant is not able to breath and run out of CO2 to produce sugars. So t</span><span>he plant wouldn't be able to complete photosynthesis.</span>

50 ml is needed for making a solution and it has 5 g of a product. how many grams of that product is needed?
Evgesh-ka [11]

Answer:

Explanation:

We are being provided with little information about the question in the study.

The 50 ml is required to make an unknown solution which has a mass of 5g,

SO, we are to determine the amount of grams that will be needed to make the product.

We are not given information about the product, as such this will be difficult and impossible to answer.

You can add the additional information required in the comment section below and further explanation and the detailed solution will be provided.

Thanks!!!
