Answer:

(3) 249 grams

Explanation:

"The triple beam balance is used to measure masses very precisely; the reading error is 0.05 gram. With the pan empty, move the three sliders on the three beams to their leftmost positions, so that the balance reads zero. <em>To find the mass of the object on the pan, simply add the numbers from the three beams</em>." (Credit: SMU Physics Website)

This is how a triple beam balance works, so using this we can solve to find the mass of the object on the pan of balance. So we can add the 3 values.

200+40+9=249 grams

Technically the reading error is 0.05 g so I'm assuming you would subtract 0.05 g of some sort, but since there is no such decimal answer in the options given, we can conclude the correct answer would be number 3, 249 grams.

how do scientists use fossil comparative anatomy and branching diagrams to explain the evolution of organism
Mnenie [13.5K]

Hi there!

In order to do fossil comparative anatomy and branching diagrams to explain the evolution of organism, scientists use <u>radiocarbonation </u><u>method</u>.

Explanation:

Carbon-14 can combine with oxygen in the atmosphere to create carbon dioxide, which is then absorbed by plants and makes its way through the food chain. The amount of carbon-14 in living plants and animals matches the amount in the atmosphere, but when plants and animals die, they no longer absorb carbon-14.

Because radiocarbon has a known rate of decay, the scientists can now determine about how long it has been since the plant or animal was alive. <u>The lower the amount of radiocarbon, the older the object.</u>

(Sometimes, C-12 is also used)

What happens to the precipitation that reaches land? Select all that apply
r-ruslan [8.4K]

The correct answers are: All of them.

- Runs off into the ocean;

The parts of the land that are close to the ocean, and are leaned towards it, especially if it is a more rocky landscape, when receiving precipitation, the water runs off directly into the ocean, though this is happening only on a relatively small area.

- Runs off into the streams and rivers;

Most of the precipitation on the land, ends up in the closest streams and rivers which increase their volume and carry the water further downstream.

- Enters the water table of groundwater;

Part of the precipitation managed to get through the soil and the rocks, and enters deeper, eventually reaching the underground reservoirs and filling them, thus contributing to the levels of the groundwater.

- Taken up from shallow soil by plants;

The plants need water for survival, so when there's precipitation, through their roots (some through their leaves), are taking water from the soil, thus spending part of it for their own needs.

When a protein is marked for destruction by having a protein called?
BigorU [14]

Answer;

-Ubiquitin

Explanation;

The major pathway of selective protein degradation in eukaryotic cells uses ubiquitin as a marker that targets cytosolic and nuclear proteins for rapid proteolysis.

Proteins marked for degradation are covalently linked to ubiquitin. Many molecules of ubiquitin may be linked in tandem to a protein destined for degradation. The polyubiquinated protein is targeted to an ATP-dependent protease complex, the proteasome.
