Vinil7 [7]3 years ago
3 0

Answer:

They accurately compare the current atmosphere with the previous one, by assessing the amount of atmospheric gases present today, with the amount of atmospheric gases trapped in ice cores that they believe are millennial, that is, they have existed for thousands of years ago.

Explanation:

As we know, it is difficult to compare current characteristics of the planet earth with characteristics that the planet had in the past, thousands of years ago. This is because the ancient characteristics on earth are not fully available to be analyzed, since most of them have been modified over time.

To do this, scientists need to find factors that may have existed thousands of years ago and assess whether these factors have any account of the characteristics of the earth. In the case of atmospheric characteristics, it is common for scientists to compare the current atmosphere with the atmosphere of thousands of years ago, with the assessment of the amount of atmospheric gases trapped in ancient ice cores, with the amount of atmospheric gases present in the atmosphere today.

Kaylis [27]

Answer:

No.

Explanation:

No, Surtsey island and Iceland newest volcanic island will not become an atoll because these islands have no underground volcanoes. The atolls are only occur when the volcanoes are present underwater and we know that these volcanoes are present on the lands not in the water so there is no possibility of having atolls in these Surtsey and Iceland volcanic islands

suppose you balanced a sample against three 10-gram masses. Suppose the sample weighed a little more than three masses, but coul
alexdok [17]

Answer: 241.5

Explanation:

Move the slider on the 100 gram beam to the first mark on the right, which is the 100 gram mark. If the pointer still is above the central mark, continue to move the slider to the right. Once the pointer drops below the central mark, move the slider back to the previous mark to the left. If the pointer drops below the central mark at 100 grams, move the slider back to zero.

Move the slider on the 10 gram beam to the 10 gram mark. Perform the same adjustments you did in the previous step until you find the appropriate slot for the 10 gram slider.

Repeat the same process with the 1 gram slider.

Add the values from each slider. For instance, if the 100 gram slider is on 200, the 10 gram slider is on 40 and the 1 gram slider is on 1.5, you would add 200 plus 40 plus 1.5 to get a total of 241.5 grams as the mass of your object in the tray.

Vikentia [17]

The one who developed the culturing technique to enrich for a certain population of microbial cells from a complex community based on a particular metabolic phenotype of interest is Martinus Beijerinck. The correct option is C.

<h3>What is culturing technique?</h3>

Culture methods involve collecting samples from the field and culturing them to detect the presence of microbes.

The number of microbial species and their influence on corrosion are estimated. Culture media for various microbes have been established.

Culturing is simply the process of growing microorganisms in special media in the laboratory. It entails the preparation of sterile medium, as well as the inoculation, incubation, and examination of microorganisms.

Martinus Beijerinck invented the technique for enriching a specific population of microbial cells from a complex community based on a specific metabolic phenotype of interest.

Thus, the correct option is C.
