NEED HELP FAST!! Question 8(Multiple Choice Worth 3 points) (01.04 HC) A group of students performed an experiment to prove the

law of conservation of energy. In the experiment, a flask containing water at room temperature was shaken vigorously for a few minutes. The table shows a partial record of the temperature of the water before and after shaking. Experimental Record Temperature Before Shaking 20 °C After Shaking Unknown What best predicts the unknown temperature? Less than 20 °C because the total energy of the system after shaking is lower Greater than 20 °C because the total energy of the system after shaking is higher Less than 20 °C, because the mechanical energy from shaking transforms to thermal energy Greater than 20 °C, because the mechanical energy from shaking transforms to thermal energy

What do we mean when we refer to a cell as differentiated?
Otrada [13]

Answer:

We mean that a cell changes to another type of cell.

Explanation:

<em>Stem cells </em>are a type of cell that has the potential to become a specialized cell, this change or differentiation, is possible thanks to the activation or deactivation of certain genes that promote (or inhibit) the expression of certain proteins that origins different types of cells (fmuscle cells, osteocytes, neurons). This differentiation happens when the cells receive cues internally ( through signals or contact between a group of cells and another or through transcription factors) or externally.

Then, a differentiated cell is a cell that had gone under the previously described process.

I hope this information is useful to you!

The producers had 6,000 kcal of energy , how much would be passed to the primary consumer?
morpeh [17]

Answer:

600 kcal

Explanation:

In an ecosystem, energy is transferred from one organism in a trophic level to another organism in another trophic level. Organisms called PRODUCERS are capable of deriving energy from the sun. However, when fed upon by PRIMARY CONSUMERS, only about 10% of the energy is transferred to them because most of the energy (90%) is lost as heat.

Hence, in this case where the producers had 6,000 kcal of energy, 10% i.e. 10/100 of 6000 = 600 kcal of energy will be transferred to the primary consumers.

why do some scientists theorize that global warming might not be the result of increases in atmospheric carbon dioxide
PtichkaEL [24]

Explanation:

In Earth’s history before the Industrial Revolution, Earth’s climate changed due to natural causes not related to human activity. Most often, global climate has changed because of variations in sunlight. Tiny wobbles in Earth’s orbit altered when and where sunlight falls on Earth’s surface. Variations in the Sun itself have alternately increased and decreased the amount of solar energy reaching Earth. Volcanic eruptions have generated particles that reflect sunlight, brightening the planet and cooling the climate. Volcanic activity has also, in the deep past, increased greenhouse gases over millions of years, contributing to episodes of global warming
