Are the current life forms similar to those of 3.8 billion years ago? How do we know?
Answer:
No, not really. Over time, organisms have grown much more complex. Photosynthesis happened around 3.4 billion years ago and respiration around 2 billion years ago. These all serve as a testimony to the fact that organisms are in fact growing more complex. We have seen photoautotrophs arise, from the simpler chemoautotrophs, and they now in fact dominate the array of producers! Organisms don't only do fermentation now; they can also do anaerobic respiration and aerobic respiration too! Thus, current life forms are a lot more different today than 3.8 billion years ago.

1. Which is the simplified version of Kepler’s third law when one of the planets being compared is Earth?
T=r^2
T^2=r^3
T^2=r
T^3=r^2
2. Which of the following are effects of melting sea ice? Select the two correct answers.
The exposed water can radiate more heat to the atmosphere than it could when insulated by the ice cover.
The exposed water reflects back more sunlight than did the ice.
The exposed water absorbs more thermal energy from the sun than did the ice
The exposed water absorbs heat and then sinks, replaced by cooler water.
3. A group of scientists are studying observable matter in a cluster of galaxies. They conclude that the cluster has only a small percentage of the mass required to keep it from flying apart. Why does the cluster remain intact?
The orbital speed of the galaxies in the cluster is slow enough to keep the cluster intact.
Dark matter provides the mass and gravity needed to keep the cluster together.
The orbital speed of the galaxies in the cluster is fast enough to keep the cluster intact.
Baryonic matter provides the mass and gravity needed to keep the cluster together.
Answer:
1. T^2=r^3 ( or T² = r³)
2. "The exposed water reflects back more sunlight than did the ice"
and
"The exposed water absorbs more thermal energy from the sun than did the ice'
3. Dark matter provides the mass and gravity needed to keep the cluster together.
Explanation:
1. Which is the simplified version of Kepler’s third law when one of the planets being compared is Earth?
Kepler's Third law of planetary motion is the ratio of the square of the orbital period of a planet is to the radius of orbit of a planet or those of other planets.
This means that, Kepler's Third law of planetary motion states that the square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit.
Mathematically, Kepler's Third last is represented as
T² : r³
= T² = r³
Therefore, the second option,T^2=r^3 which is equivalent to T² = r³ is the correct option
2. Which of the following are effects of melting sea ice? Select the two correct answers.
The melting of sea ice causes a lot of changes in the climate of an environment.
The presence of sea ice in oceans, reduces the surface area thereby causing a minimal reflection of sunlight but once sea ice melts, the surface area of the water is increased and this would results in a reflection of sunlight.
The sea ice absorbs less thermal energy or radiation from the sun(solar energy) and keeps the surface cooler but once the sea ice is melts, the resulting water, absorbs a lot of thermal energy or radiation from the sun, causing the surface of the water to be hot.
Therefore, the options "The exposed water reflects back more sunlight than did the ice" and
"The exposed water absorbs more thermal energy from the sun than did the ice" are the correct options.
3. A group of scientists are studying observable matter in a cluster of galaxies. They conclude that the cluster has only a small percentage of the mass required to keep it from flying apart. Why does the cluster remain intact?
It has been observed that galaxies present in the solar system have an attraction for one another such that they are drawn to each by force of gravity that is present in the solar system. And because of these, galaxies form clusters in the solar system.
Dark matter is a large amount of matter that is present in the solar system. Dark matter is the reason by which galaxies can form and maintain the clusters that they form around each other because it provides them with the force of gravity and sufficient mass that the galaxies require to prevent them from separating or flying away(apart) from one another
Therefore, the option "Dark matter provides the mass and gravity needed to keep the cluster together" is correct.
The simplified version of Kepler’s third law in a situation when one of the planets is compared to Earth will be T³ = T².
The effects of melting sea ice include:
The exposed water reflects back more sunlight than did the ice.The exposed water absorbs more thermal energy from the sun than did the ice.A cluster will remain intact because the dark matter provides the mass and gravity needed to keep the cluster together.
It should be noted that Kepler's third law of planetary motion simply represents the ratio of the square of the orbital period of a planet is to the radius of orbit of other planets. This can be expressed mathematically as T³ = T².

to wear away large areas of rock to see what is underneath
to test for the presence of carbonate minerals in a rock
to use as an emergency eyewash in case rock dust gets in the eyes
Answer:
C, to test for the presence of carbonate minerals in a rock
Explanation:
I did this a few weeks ago on Edge. Hydrochloric acid isn't for rock washing, they wouldn't use it to wear away rocks since it'd ruin the sample I think, and you will go blind if you put it in your eyes
Geologist carry dropper bottle filled with hydrochloric acid when doing fieldwork is to test for the presence of carbonate minerals in a rock.
Test for carbonate mineralsHydrochloric acid is used to test for presence of carbon iv oxide in compounds.
When hydrochloric acid reacts with carbonates, it produces effervescent due to the prensence of carbon iv oxides in the compound.
Geologist will use this acid (hydrochloric acid) to check if the rock sample contains carbonate minerals.

What are the effects of soil pollution?
Answer:
Soil pollution produces negative effects for the environment.
Explanation:
Soil pollution can cause many different negative effects for the environment and for organism health. Some effects are:
Nutrient imbalance - plants cannot get enough nutrients in one area since the soil is either devoid of nutrients or high one 1 nutrient and too low on othersAcidification - pollution can cause the soil to become acidified, affecting organisms and the water cycle. This acid will be harmful to plants and harmful to animals drinking it. Since it also affects the water cycle, it can affect humans by burning skin if touched or polluting our drinking sourcesContamination of groundwater - with soil pollution, it can seep deep into the Earth. This can cause natural aquafers and underground lakes/water to become polluted as well, giving us even less freshwaterAll in all, soil pollution is not positive at all and should be reduced at all costs to help nature and our planet Earth.

a. a light year unit is very small and distances in space are very small
b. a light year unit is very small and distances in space are very large
c. a light year unit is very large and distances in space are very small
d. a light year unit is very large and distances in space are very large
Answer:
i am not sure but i think is D
A light year unit is very large and distances in space are very large. So, the correct option is D.
What is Light year?A light year is defined as the larger unit of length which is used to express astronomical distances and is approximately equal to 9.46 trillion kilometers or 5.88 trillion miles.
A light-year is expressed as the distance that light travels in a vacuum in one Julian year, which is 365.25 days because it includes the term "year", the term light-year is sometimes misunderstood as a unit of time.
1 light-year = 9460730472580800 metres
Light year is used as a unit to express distances to celestial objects, for example, if a star is 4 ly away from earth, it means that light from the star will take 4 earth years to reach us.
Therefore, a light year unit is very large and distances in space are very large. So, the correct option is D.
