Why did some people think that there was evidence of intelligent life on Mars?

Answers

Answer 1

Answer:

Recent missions to Mars haven't turned up definite proof of life, but some tantalizing possibilities have been uncovered.

Explanation: Water and ice caps if there's water there's life. but its not entirely true... because there isn't any life on mars... or so NASA says National Aeronautics and Space Administration more like Never a straight answer.

Answer 2

Many people believed that there was evidence of intelligent life on Mars, because of the similarities of this planet to planet Earth and because there are indications that there was water on Mars.

Although it is currently known that there is no intelligent life on Mars, many researchers believe that this planet has been inhabited in the past.

There is some evidence that allows this speculation to be established. Among this evidence, scientists claim that:

Mars has some characteristics similar to planet Earth.Many rocks on Mars have organic molecules.There is evidence that the surface of Mars once had water about two thousand years ago.There is water at the poles of Mars.There are water flows on the planet's hot slopes that are resistant to freezing.

With this, we can see that, according to the evidence, it is not possible to affirm that there was already intelligent life on Mars, but that the planet has the possibility of having been populated by microorganisms.

Hydrogen bonds can be found between no other molecules except water.

Answers

Answer:

Without hydrogen bonds, water molecules would move faster more rapidly, with less input of heat energy, causing the temperature to increase more for each calorie of heat added.

Explanation: This would also greatly reduce the amount of heat energy needed for phase changes from ice to liquid, and from liquid to vapor.

Answer: Not really a question but....Two molecules of water can form a hydrogen bond between them that is to say oxygen-hydrogen bonding; the simplest case, when only two molecules are present, is called the water dimer and is often used as a model system.

Answer:

An aerobic pathway consisting of glycolysis, the Krebs cycle, and the electron transport chain

Explanation:

It's aerobic because there is oxygen available while if it were anaerobic, no oxygen would be present.

Hope it helps :)

Natasha is making a model of cellular respiration. Her model shows the pathway followed when there is enough oxygen available, so her model shows it is an aerobic pathway consisting of glycolysis, the Krebs cycle, and the electron transport chain, which is option C.

What is the significance of respiration in living beings?

Cellular respiration is either carried out when there is an abundance of oxygen, called "aerobic respiration," when there is enough oxygen present to lead to the running of the glycolysis, Krebs cycle, and electron transport chain to form energy, which is in a normal condition of a cell. while fermentation takes place when oxygen is not enough.

Hence, Natasha is making a model of cellular respiration. Her model shows the pathway followed when there is enough oxygen available, so her model shows it is an aerobic pathway consisting of glycolysis, the Krebs cycle, and the electron transport chain, which is option C.

A marshy area dries up, and most of the organisms in a population of flowers die. However, some of the flowers have adaptations that allow them to survive the change. If the land stays dry, what will the population of flowers be like several generations from now?

A. The population will have greater genetic diversity because the additional stress caused by lower water levels will result in increased immigration.

B. The population will have the same genetic diversity as when the area was marshy.

C. The genetic diversity will be less than in the original population, as more flowers will have the adaptations to live in the drier conditions.

D. The flowers will all die off because they could not survive in the drier conditions.

Answers

Answer:

Explanation:

All that is left are the plants capable of surviving in dry conditions; whereas before there were plants that thrived in more marshy conditions. Therefore decreased genetic diversity. The adaptations of the plants will be much less diverse.

A manufacturing factory is accused of emitting high levels of CO2 into the ecosystem. The factory burns coal to heat steel
drums. The factory uses lake water to cool the drums. The water is poured over the drums and then emptied back into the
lake
Scientist A claims the factory is responsible. The burning of coal releases excess CO2 into the atmosphere. This excess CO2 is
transferred to all areas. The CO2 is not lost throughout the system.
Scientist B clams the factory is not responsible. The CO2 is released directly into the atmosphere, not into the lake. The CO2 is
lost into the upper layers of the atmosphere and not cycled back into the ecosystem
The model represents the cycle of carbon in the atmosphere. Which key issue illustrated in the model would best support Scientist
A's claim?
A)
The model shows a factory creating excess levels of CO2
B)
The model depicts a continuous cycle. An increased level in one area will
increase levels throughout.
The model depicts multiple cycles. The atmospheric cycle would show an
increased level of CO2
The model shows high levels of carbon in the lake. Any change to this level
will have a greater impact on the atmosphere.
D)

Answers

The key issue that must be illustrated in the model and best support Scientist A claim is as follows:

The model depicts multiple cycles. The atmospheric cycle would show an increased level of CO2.

Thus, the correct option is C.

What is an Ecosystem?

An ecosystem may be defined as a place or an area in which individuals of different species live together and interacts with one another for the purpose of food, shelter, and space.

According to Scientist A, the factory is responsible for the excess level of carbon dioxide in the atmosphere. This is absolutely true because the factory burns coal that liberated a high amount of CO2 into the environment.

Apart from this, the factory uses lake water to cool the drums. The water is poured over the drums and then emptied back into the lake. This increases the concentration of CO2 in the lake as well.

Therefore, the correct option for this question is C.

Compared to the use of many gasoline vehicles with only one person per vehicle, this method of transportation conserves more fossil fuels.

Explanation:

A form of transportation —such as the subway or streetcar— has capacity for many passengers and uses electricity as an energy source. This means fewer people using gasoline-vehicles, which leads to savings in fossil fuels, such as gasoline or diesel.

The decrease in the use of fossil fuels in vehicles has been proposed as an alternative to reduce environmental pollution and its consequences. One alternative is to consider mass transport vehicles that use alternative energy, a sustainable form of transport.

None of the other options are correct, as they involve more or the same use of fossil fuels per person.

You never have to worry about wastewater becoming contaminated because it can run through local treatment plants, true or false?

Answers

A person still have to be worried about wastewater becoming contaminated even though it passes through local treatment plants.

Wastewater refers to the water they has been used. It consists of the substances like human waste, oils, chemicals , food scraps etc.

Even though used water runs through local treatment plants, it should be noted that not all the solid waste are removed as some of the waste will still end up getting into nearby rivers or streams and this can result in contamination when one eventually uses such water.

In conclusion, one still has to be worried even though the wastewater runs through local treatment plants. Therefore, the correct option is False.

Group of answer choices increases, increases remains the same, remains the same decreases, decreases increases, decreases

Answers

energy increases frequency decreases :)

When two boys move the string, the energy increases, and the frequency increases. Thus, the correct option for this question is A.

How are energy and frequency of waves related to one another?

The energy and frequency of waves are always directly related to one another. It means that when energy increases, frequency increases. When energy decreases, the frequency decreases.

Now, according to the context of this question, when two boys begin to move the string faster and faster, the energy gradually increases with an increase in frequency as they both are directly related to one another.

Therefore, when two boys move the string, the energy increases, and the frequency increases. Thus, the correct option for this question is A.
