Why can the geologic time scale change?
Absolute time measurements can be used to calibrate the relative time scale, producing an integrated geologic or "geochronologic" time scale. The overall duration and relative length of these large geologic intervals is unlikely to change much, but the precise numbers may "wiggle" a bit as a result of new data.

An interglacial is a period of time that occurs between Ice Ages. During previous interglacials, the CO2 levels in the atmosphere were about 300 parts per million (ppm). In 2013, they were approximately 420 ppm. Rounding to the nearest percent, what is the percent increase in CO2 between these two time periods?
Answer:
40% increase
Explanation:
Percentage Increase Formula:
Percentage Increase=[(Final Value−Starting Value)/|Starting Value|] ×100%
To Calculate Percentage Increase:
1) Subtract final value (later value) minus starting value (initial value)
2) Divide that amount by the absolute value of the starting value (initial value)
3) Multiply by 100 to get percent increase
Keep in mind: If the percentage is negative, it means there was a decrease and not an increase.
So for your problem,
[(420-300)/300]*100% = 40% increase

Polycythemia is a disease which causes an excessive number of red blood cells to be produced. The disease is the result of a faulty gene. How would the flow of blood be affected by this condition?
Answer:
The blood flow would be delayed, since the amount of red blood cells increases the total density of blood volume, which is why the greater the quantity of blood, the thicker the blood will be.
This, as a consequence, could cause thickening of the blood, thus becoming denser, affecting the continuous laminar flow inside the blood vessels, this means that the flow is not unidirectional, but when it is delayed, it produces a kind of micro whirlpools that hinder healing, circulation, oxygenation and stimulate the appearance of deep and superficial clots or thrombosis.
Explanation:
It is important to clarify that the polycythemia which we are talking about is very excessive, very noticeable, unlike the physiological polycythemia that the body does when faced with an increase in height and a decrease in partial pressure of oxygen.
This is important for you to know, because the body when we climb a mountain or climb, or the partial pressures of oxygen decrease in the atmosphere, takes as a compensation mechanism the increase of red blood cells to maintain the oxygenation of the body, but this being PHYSIOLOGICAL is not excessive.
Polycythemia due to genetic failure such as the one we are writing now is a pathology because we are facing an excessive EXCESS of red blood cells, where phenomena of jaundice and hemolysis can also occur due to the great imbalance that is generated in the entire body
why is it important for your body to return to its balanced and steady state
Answer:

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.

30. Lithification occurs when sediments are squeezed together by the weight of overlying sediments on top of them.
The correct blanks are Intrusive, Slow, deposited, cementation, Regional, Contact, Foliation, volcanic, igneous, lithified, and Compaction.
Igneous rocks are a type of rock that forms from the solidification and crystallization of molten material, known as magma or lava.
Intrusive igneous rocks, also known as plutonic rocks, form when molten magma cools and solidifies beneath the Earth's surface.When molten magma or lava cools slowly, it provides sufficient time for the atoms and molecules within the molten material to arrange themselves in an orderly manner. The process of deposition refers to the settling or accumulation of sediments, which are fragments of rocks, minerals, organic matter, or other particles, onto a surface.Cementation is a process in which minerals in fluid form, often dissolved in groundwater, precipitate and crystallize within the pore spaces of sedimentary materials. During regional metamorphism, large volumes of rock are subjected to significant heat and pressure, typically deep within the Earth's crust. Contact metamorphism, also known as thermal metamorphism, occurs when a rock comes into direct contact with magma or an igneous intrusion.Foliation refers to the parallel alignment of minerals or the development of compositional layering within a metamorphic rock. Volcanic igneous rocks are classified as extrusive igneous rocks because they are formed from lava that has extruded onto the surface.The process of lithification involves the transformation of loose sediments into solid sedimentary rocks.Compaction is a key process in the lithification of sedimentary rocks. It takes place as layers of sediment accumulate over time, and the weight of the overlying sediments exerts pressure on the underlying layers.Thus, the correct blanks are Intrusive, Slow, deposited, cementation, Regional, Contact, Foliation, volcanic igneous, lithified, and Compaction.

What plants use to make food?The plants use sunlight, water, and carbon dioxide to make sugars as well as food. Organisms can be divided into autotrophs and heterotrophs according to their pathway of producing food and energy. Heterotrophs are that organism which depend on another organism for their food and energy. They get their energy from carbohydrate, protein, and fat.
Those organisms that are able to make and produce energy from energy-containing organic molecules such as glucose from inorganic raw material such as water and by using light energy such as sunlight are autotrophs. Plants are the prime autotrophs, they produce their food and energy which is sugar from water, sunlight and carbon dioxide using photosynthesis.
