Answer:

October 17, 2019

The Moon, otherwise known as Luna, is the only natural satellite of Earth. It was created 4.6 billion years ago, and it is widely accepted that it was created when Earth collided with a planet-sized object called Theia. It’s the fifth-largest moon in our solar system and is the second brightest object in the sky (after the Sun).

Explanation:

History of The Moon

Called Luna by the Romans, Selene and Artemis by the Greeks, and many other names in other mythologies.

The Moon, of course, has been known since prehistoric times. It is the second brightest object in the sky after the Sun. As the Moon orbits around the Earth once per month, the angle between the Earth, the Moon and the Sun changes; we see this as the cycle of the Moon’s phases. The time between successive new moons is 29.5 days (709 hours), slightly different from the Moon’s orbital period (measured against the stars) since the Earth moves a significant distance in its orbit around the Sun in that time.

answer 1:

Environmental Pollution occurs in different forms; air, water, soil, radioactive, noise, heat/ thermal, and light

Air Pollution

Water Pollution

Soil pollution

Noise pollution

Radioactive pollution

Light pollution

Humans are the main cause of water pollution, which is triggered in many ways: by the dumping of industrial waste; due to temperature rise, that cause the alteration of water by reducing the oxygen in its composition; Or due to deforestation, which causes sediments and bacteria to appear under the soil

Most of this air pollution we cause results from the burning of fossil fuels, such as coal, oil, natural gas, and gasoline to produce electricity and power our vehicles. Carbon dioxide (CO2) is a good indicator of how much fossil fuel is burned and how much of other pollutants are emitted as a result.

Effects:

Nutrient pollution can cause toxic algal blooms in drinking water sources that create toxins that kill fish and other aquatic animals. Direct exposure to this toxic alga causes serious health problems in humans including neurological effects, respiratory problems, stomach and liver illness, and rashes.

answer 2:

The Industrial Revolution brought rapid urbanization or the movement of people to cities. Changes in farming, soaring population growth, and an ever-increasing demand for workers led masses of people to migrate from farms to cities. Almost overnight, small towns around coal or iron mines mushroomed into cities.

anwer 3:

advantages are

1_A Fuel Supply That Never Runs Out

2_Zero Carbon Emissions

3_Cleaner Air and Water

4_A Cheaper Form of Electricity

5_Renewable Energy Creates New Jobs

disadvantages are

1_Higher Capital Costs

2_Electricity Production Can Be Unreliable

3_Energy Storage Is a Challenge

4_It’s Impacted by Environmental Conditions

5_Renewables Still Have a Carbon Footprint

anwer 4:

Hazardous waste can be treated by chemical, thermal, biological, and physical methods. Chemical methods include ion exchange, precipitation, oxidation and reduction, and neutralization. Among thermal methods is high-temperature incineration, which not only can detoxify certain organic wastes but also can destroy them.

answer 5:

You could do this by:

1_Try to stay away from disposable goods. In particular, paper plates, cups, bottles, and plastic utensils.

2_Buy durable and reusable goods. ...

3_Pack your lunch in a reusable box rather than foil or cling film.

4_Buying products with less packaging. ...

5_Buying products in bulk.

I WISH THIS WILL BE HELPFUL, GOOD LUCK :)

What virus structure is similar in function to a cell membrane?
Korolek [52]

Answer:

viral envelope

The phospholipids in the viral envelope are similar to those in the plasma membrane of an infected host cell. The viral envelope is, in fact, derived by budding from that membrane, but contains mainly viral glycoproteins.

A postsynaptic neuron has three presynaptic inputs - from neurons X, Y, and Z. Stimulation of neuron X causes the postsynaptic n
xenn [34]

Answer:

Y is probably excitatory and Z is probably inhibitory

Explanation:

  • Two neurons communicate with each other generally by releasing neurotransmitters.
  • The neuron which releases the neurotransmitter is termed as presynaptic neuron and the neuron to which the neurotransmitter binds to exert its effects is called as postsynaptic neuron.
  • Based on the nature of the neurotransmitter released, the presynaptic neurons can either be inhibitory or excitatory in nature.
  • The change in the membrane potential of the postsynaptic neurons depends on the total sum of inputs coming from different pre synaptic neurons at a given time.
  • From the given situation, the stimulation by X alone is causing deploarization of 0.5 mV which shows that it is causing excitation, and since depolarization is increasing when X and Y are stimulaneously stimulated Y is also excitatory in nature. However the depolarisation is not occurring when X and Z are stimualted together and hence, Z is probably inhibitory in nature.
