Answer:
c. 2
Explanation:
Given that
Parent to daughter ratio = 1:3
Based on the above information, after considering the 1 half-life of radioactive isotope there is one-half of the real radioactive atoms of the parent left also the equivalent number of daughter atoms produced
Therefore after one half, the ratio between parent and daughter atom is 1:1
Now after the second half, half of the left parent atom would be transformed into the daughter cells
This remains a quarter of parent atom and 3 quarter of daughter atoms
So, the ratio of 1:3 would be shown after 2 half-lives

Bioplastics made from corn grown using industrialized agricultural methods would have a smaller ecological footprint that bioplastics made from native prairie switchgrass.
A. True
B. False
Answer:
A this is true
Explanation:
i had to answer this question and i got it right
Bioplastics made from corn grown using industrialized agricultural methods would have a smaller ecological footprint that bioplastics made from native prairie switchgrass.
Thus, the correct option A.
What are Bioplastics?Plastics made from renewable biomass sources, such as plant fats and oils, maize starch, straw, woodchips, sawdust, and recovered food waste, are known as bioplastics.
Some bioplastics are made by processing polysaccharides (such as starch, cellulose, chitosan, and alginate) and proteins (such as soy protein, gluten, and gelatin) directly from natural biopolymers.
Other bioplastics are made chemically from sugar derivatives (such as lactic acid) and lipids (such as oils and fats) from either plants or animals, or biologically by fermentation of sugars or lipids.
Contrarily, conventional plastics like fossil-fuel plastics, often known as petro-based polymers, are made from natural gas or petroleum.
Bioplastics have the advantage of not requiring fossil fuel as a raw material, which is a limited and unevenly distributed resource with political and environmental implications.

Based on the population density maps above, what can be inferred about Britain’s migration patterns? A. The population of Britain was greater in 1701 than in 1911. B. Britain was more densely populated in 1911 than in 1701. C. Fewer people lived in urban areas in 1911 than in 1701. D. The northern part of the island was more densely populated than the southern part in 1701.
Answer: B. Britain was more densely populated in 1911 than in 1701.
Explanation:
In the map below, the darker colors are used to denote a heavier population density. Looking the map you will notice that there are more darker colors in 1911 then in 1701 which would mean that Britain as a whole was more densely populated in 1911 than in 1701.
This was down to Britain becoming a World Military and Economic power. These two factors meant that more prosperity was due to Britain which enabled it to reduce the mortality rate of its people in the so called Mortality Revolution.

What type of rock is most likely to form in an earthquake zone?
A. Extrusive igneous rock
B. Sedimentary rock
C. Metamorphic rock
D. Intrusive igneous rock
Answer:
C. metamorphic rock
Explanation:
Although metamorphic rocks typically form deep in the planet's crust, they are often exposed on the surface of the Earth. This happens due to geologic uplift and the erosion of the rock and soil above them. At the surface, metamorphic rocks will be exposed to weathering processes and may break down into sediment. hope this helps you :)

A climate classification based on the geographic determinants of climate, such as latitude or elevation, is an example of a(n)'
Answer:
Genetic classification.
Explanation:
The genetic classification of climate is based on determinants of climate such as, location with respect to wind and pressure belts, latitudinal control of temperature, effects of mountains.
Genetic classification also relies on information about climatic elements like solar radiation, air masses, and pressure systems.
This classification is qualitative and climate is designated in a subjective manner with no rigorous scientific research done.

5. How were Earth's core and mantle formed?
Answer:
God created the earth Genesis chapters 1 - 2
The discontinuity separating the crust from the mantle is named as: A.Mohorovicic B.Conrad C.Reppetty D.Gutemberg
Answer:
A.mohorovic
Explanation:
The Mohorovičić discontinuity (/moʊhəˈroʊvɪtʃɪtʃ/ MOH-hə-ROH-vitch-itch, Croatian: [moxorôʋiːtʃitɕ]),[1] usually referred to as the Moho discontinuity or the Moho, is the boundary between the Earth's crust and the mantle. It is defined by the distinct change in velocity of seismological waves as they pass through changing densities of rock.[2]
The Moho lies almost entirely within the lithosphere.[3] Only beneath mid-ocean ridges does it define the lithosphere–asthenosphere boundary. The Mohorovičić discontinuity is 5 to 10 kilometres (3–6 mi) below the ocean floor, and 20 to 90 kilometres (10–60 mi) beneath typical continental crusts, with an average of 35 kilometres (22 mi).
Named after the pioneering Croatian seismologist Andrija Mohorovičić, the Moho separates both the oceanic crust and continental crust from underlying mantle. The Mohorovičić discontinuity was first identified in 1909 by Mohorovičić, when he observed that seismograms from shallow-focus earthquakes had two sets of P-waves and S-waves, one that followed a direct path near the Earth's surface and the other refracted by a high-velocity medium.[4]

Which situations describe increasing atmospheric stability (choose all that apply): Group of answer choices daytime solar heating of the surface increases surface temperatures cold air from land moves over a warm lake rising surface temperatures on a calm, sunny summer day environmental lapse rate increasing with time a North wind brings in cold air from Canada, lowering surface temperatures Surface air cools while air aloft warms
Answer:
daytime solar heating of the surface increases surface temperatures.
Explanation:
Atmospheric stability is the condition where the air is generally considered to be stable than earlier due to the certain changes that take place over the period of time which are associated with the weather and climatic variability. As the colder air mass is denser than the warmer and lighter air mass thus reverse in the condition leads to instability.units use to measure temperature
Explanation:
Hey, there!!
Temperature is defined average kinetic enegry of the molecules contained in the body or substance. The SI unit of temperature is kelvin. We generally measure temperature in:
Fahrenheit (ranges from 32°f to 212° f)Kelvin (ranges from 273° k to 373° k)centrigrade ( ranges from 0°c to 100° c)Hope it helps...
