What is a difference between Newston’s laws of motion and Elinstein’s theory of relativity ?

DENIUS [597]

Sir Isaac Newton quantified the gravity between two objects when he formulated his three laws of motion. ... Yet Newton's laws assume that gravity is an innate force of an object that can act over a distance

In 1905, Albert Einstein determined that the laws of physics are the same for all non-accelerating observers, and that the speed of light in a vacuum was independent of the motion of all observers. This was the theory of special relativity. It introduced a new framework for all of physics and proposed new concepts of space and time.

Einstein then spent 10 years trying to include acceleration in the theory and published his theory of general relativity in 1915. In it, he determined that massive objects cause a distortion in space-time, which is felt as gravity.

Based on the results of the feeding experiment, what conclusions can you draw? select all that apply. (for help interpreting the

enyata [817]

The question posted above is incomplete, here is the complete version:

To find out which ingredient the cockroaches are refusing, you carry out a controlled experiment. Hydramethylnon is dissolved in oleic acid before being mixed with corn syrup to prepare the poisoned bait, so you should test all three ingredients. Suppose you conducted a feeding trial to test each ingredient. In the trial, a set of four agar dishes, three containing all except one ingredient and one with all three ingredients (the control), were weighed and placed 3 cm apart on the kitchen floor in an infested apartment. After two days, the dishes were weighed again to measure food consumption. You then repeated the trial 4 times and averaged the results. Here are the results from your experiment.

Tested (absent) diet component Average food consumed (mg/day)

Hydramethylnon 16

Oleic acid 12

Corn syrup 71

Control (all three ingredients present) 15

Based on the results of the feeding experiment, what conclusions can you draw? Select all that apply. (For help interpreting the results see the hints.)

1. Roaches ate about the same amount from the dish with no hydramethylnon as they did from the control dish.

2. Roaches ate about the same amount from the dish with no oleic acid as they did from the control dish.

3. Roaches ate about the same amount from the dish with no corn syrup as they did from the control dish.

4. Roaches are refusing hydramethylnon.

5. Roaches are refusing oleic acid.

6. Roaches are refusing corn syrup.

ANSWER:

The conclusions that apply include the following:

1. The roaches ate about the same amount from the dish without hydramethlynon as they did from the control dish.

6. Roaches are refusing corn syrup.

As we can see from the results obtained above, the amount of food consumed by the roaches when hydramethylnon is absent (16 mg/day)in the feed and that consumed from the control dish (15 mg/day)is almost the same quantity. From the results also, it can be seen that the highest quantity of food (71 mg/day) was consumed when corn syrup was absent in the feed, which implies that the roaches are refusing corn syrup.

Lactobacillus in yogurt, some Escherichia coli in the intestines of humans and animals, and Rhizobium that fixes atmosphere nitr

alisha [4.7K]

Answer: a. True.

Explanation:

Lactobacillus is a genus of gram-positive, facultative or microaerophilic bacteria that produce lactic acid. They are normally found in different parts of the body such as the mouth, digestive tract and vagina. Lactobacilli usually do not cause disease, although they can cause dental caries. Some lactobacilli have a homofermentative metabolism, that is, they produce lactic acid from sugars, which makes their environment acidic and inhibits the growth of pathogenic bacteria. Some species of Lactobacillus are used in the industry for the production of yogurt, cheese and other fermented foods.

Escherichia coli is a bacterium that is part of the microbiota of the gastrointestinal tract of various animals. It is a gram-negative bacillus, facultative anaerobe, and the most abundant commensal of the microbiota of the gastrointestinal tract where, together with other microorganisms, it is essential for the correct functioning of the digestive process. It also participates in the production of B and K vitamins.

Rhizobium is a genus of gram-negative soil bacteria that fix atmospheric nitrogen and live in symbiosis with certain plants (such as leguminous plants) in their roots, after a process of infection induced by the plant itself through the secretion of lectin, to which they provide the nitrogen necessary for the plant to live and which in return gives it shelter. Fixation is the combination of molecular nitrogen (N2) with hydrogen or oxygen to give ammonium or oxides that are incorporated into the biosphere. Molecular nitrogen, which is the major component of the atmosphere, is inert and not directly usable by most living things. Therefore, it involves the incorporation of a significant amount of nitrogen into the biosphere.

Therefore, all three are considered beneficial.
