An object of the same mass has three different weights at different times. Which statement is possible? The object gains matter and then loses it. The object started on Earth, was transported to space, and was deposited on the moon. The object started at the bottom of a hill, then moved to the top of the hill, and then moved back down to the bottom of the hill. The object changes shape, which changes its weight.

Answers

Explanation:

Hey, there!!

The possible reason is option no. b.

Because

for the first option its absolutely wrong. For the second option there is variation of gravity in different places so, the weight differes. (as w= m.g)For the third option, the weight changes when the object is kept at top at once and low at once but for the third time again the object is replaced at same place. so, it only gives two different weights.4th option is incorrect.

so, i think the answer is option B.

the answer has to be b

A terrarium is a small, enclosed ecosystem. If you change certain aspects of the terrarium, the climate that exists inside it will also change. Examine the image of a terrarium. Then identify one attribute of the terrarium that you could change to alter the climate inside. How would this change mimic the climate changes that we see on Earth?

Answers

Answer: Putting a lid on the terrarium will increase the humidity.

Explanation:

Putting a lid on the terrarium will increase the humidity.

What is Humidity?

Humidity is a measurement of the air's water vapor content. If there is a lot of water vapor in the air, the humidity will be high. As the humidity increases, it feels more humid outside.

In weather reports, humidity is frequently described using the word "relative humidity." The percentage of the maximum quantity of water vapor that the air can hold at a given temperature that is actually present in the air is referred to as relative humidity.

A chilling -10 degrees Celsius in the air (14 degrees Fahrenheit). At this temperature, the air can only hold 2.2 grams of water per cubic meter.

Therefore, Putting a lid on the terrarium will increase the humidity.

If the gasoline floats on the surface of the puddle, what does that tell you about how its density compares to that of water? Explain your answer.

Answers

It tells that gasoline is less dense than water, because according to Archimedes Law states that any body completely or partially submerged in a fluid is acted upon by an upward, or buoyant, force, the magnitude of which is equal to the weight of the fluid, displaced by the object. So, when gasoline is put in water, it floats, it means that the buoyancy force is greater than gasoline's weight. It means that the weight of the same volume of water is more than the weight of the same volume of gasoline. It means that water has more density.

It tells that the gasoline has a lower density because it is floating in water else it will sink.

Which of the following is an example of aerobic respiration? A.Lactic acid fermentation in human muscles B.Physical exchange of gases in human lungs C.Respiration during vigorous physical exercise D.Breaking down of glucose with oxygen inside an animal cell

Answers

Since Aerobic respiration is the aerobic catabolism of nutrients to carbon dioxide, water, and energy, and involves an electron transport system in which molecular oxygen is the final electron acceptor . therefore Only D !

D. Breaking down of glucose with oxygen inside an animal cell is an example of aerobic respiration.

Lactic acid fermentation occurs in human muscles and it is not a type of aerobic respiration as it occurs in the absence of oxygen gas. In this process, lactate or lactic acid is produced by the glucose. Physical exchange of gases in human lungs is called breathing. Respiration during vigorous physical exercise is an example of anaerobic respiration because vigorous physical exercise creates deficiency of oxygen. Aerobic respiration is a type of cellular respiration in which the glucose is broken down to release energy in the form of ATP or adenosine triphosphate in the presence of oxygen. This type of respiration occurs in both animal and plant cells. Hence, breaking down of glucose with oxygen inside an animal cell is an example of aerobic respiration.

You wish to study the impact of synthetic estrogen like hormones on the health of whales (and people). Select the organism from the table below that would be best to use in your research. Why did you select this organism?

Yeast------------------Single celled, eukaryotic (contains a nucleus)
Fruit fly---------------Multicellular, eukaryotic, invertebrate, arthropod
Zebrafish-------------Multicellular, eukaryotic, vertebrate, fish
Mouse-----------------Multicellular, eukaryotic, vertebrate, mammal


Fruit flies, because they are multicellular like whales
Mouse, because they are mammals like whales
Yeast, because they are eukaryotic like whales
Zebrafish, because they live in the water like whales

Answers

Answer:

Because humans are multicellular, eukaryotic (contains a nucleus), vertebrates, and mammals, the best organism to test the synthetic hormones on would be a mouse.

Explanation:

Humans and whales are multicellular (they have many cells) and their cells are eukaryotic (contain a nucleus). They also have a backbone (spinal column), which makes them a vertebrate. Finally, all humans and whales are mammals. Therefore, to get the best results, the testing should be performed on a mouse.

Performing the experiment on yeast would give good results for singular-celled organisms, like protozoa.Performing the experiment on a fruit fly would give good results for multicellular invertebrates, like spiders.Performing the experiment on zebrafish would give good results for all fish in general.

The answer is a mouse

Explanation:

Jupiter is the fifth planet from our Sun and is, by far, the largest planet in the solar system – more than twice as massive as all the other planets combined. Jupiter's stripes and swirls are actually cold, windy clouds of ammonia and water, floating in an atmosphere of hydrogen and helium. Jupiter’s iconic Great Red Spot is a giant storm bigger than Earth that has raged for hundreds of years.

With a radius of 43,440.7 miles (69,911 kilometers), Jupiter is 11 times wider than Earth. If Earth were the size of a nickel, Jupiter would be about as big as a basketball.

From an average distance of 484 million miles (778 million kilometers), Jupiter is 5.2 astronomical units away from the Sun. One astronomical unit (abbreviated as AU), is the distance from the Sun to Earth. From this distance, it takes Sunlight 43 minutes to travel from the Sun to Jupiter.

There are many 3D methods where the efficiency, lifespan, repeatability, along with the comfort of work are poorer than in the case of 2D systems, which again is a disadvantage.

3D methods have become a lot more prevalent and are used in the area of cancer research, they can also be applied in tissue engineering. Cell culture is a commonly utilized in vitro tool for expanding our understanding of cell biology, tissue shape, disease mechanisms, medication action, protein production, and tissue engineering development.

The Tennessee court decided in the Scopes trial that scopes broke the law by teaching evolution. Therefore, option (A) is correct.

The Tennessee court found that John T. Scopes violated the Butler Act by teaching evolution in a state-funded school. The Butler Act banned human evolution in Tennessee schools. High school teacher Scopes purposefully taught evolution to dispute the law's constitutionality and promote academic freedom.

Scopes was convicted and fined in 1925. The trial symbolised the US conflict between contemporary science and old religion.

The Butler Act was upheld and Scopes found guilty, but the case ignited debate on evolution in education and church-state separation. It led to landmark judgements on academic freedom and constitutional rights in education and legal disputes over teaching evolution in public schools. Therefore, option (A) is correct.
