Answer:
It’s Carbon -12,potassium, and argon.
Explanation:
The three elements used by geologist to measure the age of organism’s are carbon-12, potassium, and argon. Thus, option D is correct.
Which method is used to determine of age of organism’s remains?The age of organism’s remains is determined by two methods of calculation such as carbon dating and by radioactive calculations as all living things are made up of carbon. It calculates the age by estimating at what time the fossil was alive.
Now a days, instead of the decay of carbon-14 and nitrogen-14, radioactive isotopes are used for determining the age of organism’s remains, known as Radiocarbon dating.
The radioactive isotopes of different elements present in our environment. The older elements are uranium, argon etc are used to measure age of a fossil.
The use of older naturally available radioactive elements is more successful in determination of age of organism’s remains. Hence, option D is correct.

Fill in the blank. An object can be broken up by a planet's gravity once it passes the _______. The Jovian planets are composed primarily of _______ and helium. Hydrogen and helium don't exist in Earth's _______ because the terrestrial planets of Mercury, Venus, Earth, and Mars couldn't exert a strong gravitational pull on hydrogen and helium gas within the nebula. _______ is the planet closest to the sun, has almost no atmosphere, and what little atmosphere exists is constantly getting blown away by solar wind. The atmosphere of _______ is very hot and dense, comprised of approximately 95 percent carbon dioxide, and the surface is composed of molten bedrock. Respond to the following based on your reading. Briefly describe why an object might break up under the force of gravity as it approaches a planet. What happens if the planet is very dense? What if the planet is less dense? Briefly explain why the Jovian planets formed farther away from the sun than the terrestrial planets.
Answer:
1. Roche limit
2. hydrogen
3. atmosphere
4. Mercury
5. Venus
6. When an object passes the Roche limit, the strength of gravity on the object increases. If the density of the planet is higher, then the object can break up farther away from the planet. If the density is lower, then the Roche limit is located closer to the planet.
7. Farther out in the solar system, beyond the frost line, hydrogen was at a low enough temperature that it could condense. This allowed hydrogen to accumulate under gravity, eventually forming the Jovian planets.
Explanation:
The universal pull of attraction that is present on the planet is called gravity. The gravitational pull results in attraction force between planets, stars, galaxies etc.
The blanks are:
Blank 1: Roche limit
Planets have a limit to which they can entertain objects in their atmosphere. The limit at which the gravity of the planet breaks object is called the Roche limit.
Blank 2. Hydrogen
Jovian planets include Jupiter, Uranus, Saturn and Neptune and have rocky surfaces.Primary gases found on the Jovian planet are helium and hydrogen along with traces of ammonia, methane etc.Blank 3. Atmosphere
The atmosphere of the earth does not have helium and hydrogen in them as the gravitational pull by other planets like Mercury, Mars and Venus are not able to exert a pull on helium and hydrogen-containing atmospheres.
Blank 4. Mercury
The planet closest to the sun is mercury and it has no atmosphere and is the smallest planet.
Blank 5. Venus
The second closest planet to the sun and the hottest planet of the solar system is Venus it has a dense atmosphere with 95% carbon dioxide in its atmosphere.
6. The object passing the Roche limit goes through increased gravity which breaks the object.
If the planet is dense then the object breaks further from the planet while when the planet is less dense then the Roche limit will be located close to the planet.
7. The Jovian planets formed far away from the Sun because beyond point Hydrogen accumulated due to low temperature and formed the Jovian planets.

Biodiversity is the variety of life in an area. Think about the
process of succession. How does biodiversity change during
succession?
Biodiversity increases through the process of succession.
Biodiversity decreases through the process of succession.
Biodiversity does not change during the process of
succession.
Answer:
It Increases.
Explanation:
Biodiversity is the the variety of living organisms such as wildlife and plants. The number of organisms and biomass amount further increases in the ecosystem in which the process of succession is occurring.
The numbers will stabilize when a climax stage has occurred in succession, which will not change the biodiversity.
The sort of many lives living together in an ecosystem or habitat is called biodiversity. Biodiversity increases during the process of succession.
What is succession?Succession is the biological and chemical process of change and formation of the habitat and species of a particular place during a period. It can be primary or secondary.
The formation of the new habitat in barren land is primary succession while the formation of the ecosystem in a once habituated place is secondary succession.
Biodiversity always increases in the succession process till the climax community is not achieved till the conditions are well balanced.

D. Compartmentalization within the chloroplast keeps the light-dependent and light-independent reactions in close proximity but separated.
Answer:
A. The separation of functions ensures that photosynthesis can continue running no matter what light conditions are present.
Explanation:
Think of the shape of a wave. It looks like a squiggly line. We know the highest part of that line is the peak. The wavelength is the distance between wave peaks. Waves of the same type can differ in wavelength. For example, the wavelength of light waves determines its color. Amplitude is the measurement of a wave's height. It is measured in two ways. Peak-to-peak amplitude is the distance between the peak (the topmost part of a wave) and the trough (the lowermost part). Semi-amplitude is half the peak-to-peak amplitude. Most of the time when people refer to "amplitude," they are referring to the semi-amplitude: the distance from the middle of the wave to the top, or the middle of the wave to the bottom. The amplitude of a sound wave determines its volume.
Which of the following best explains the relationship between peak-to-peak amplitude and semi-amplitude?
A Semi-amplitude is half the distance of the peak-to-peak amplitude.
B Semi-amplitude is the same distance as the peak-to-peak amplitude.
C Semi-amplitude is double the distance of the peak-to-peak amplitude.
D Semi-amplitude is always greater than the peak-to-peak amplitude.
Answer:
A Semi-amplitude is half the distance of the peak-to-peak amplitude.
Answer:
A Semi-amplitude is half the distance of the peak-to-peak amplitude
Explanation:
Semi-amplitude is from the middle of the wave to the top or bottom
