Answer:
Approximately 338
Explanation:
Since each generation of the insect is approximately 1.5 times that of the previous generation. Therefore,
Population of insect in the first generation = 100
Population of insect in the second generation = 1.5 × 100
= 150
Population of insect in the third generation = 1.5 × 150
= 225
Population of insect in the fourth generation = 1.5 × 225
= 337.5
The population of insect in the fourth generation is approximately 338.
I believe photosynthesis produces ATP and oxygen. Answer C.
Answer:
The process that Mildred used is known as Radiocarbon dating
Note: The question is incomplete. The complete question is given below:
Mildred collects a sample of fossilized plant material. She takes it back to her lab to run some tests on it. Mildred is able to measure the amount of carbon-14 in her sample and compare this to the amount of carbon-12 in it. She uses this information to calculate that the fossil is 4,500 year old. The process that Mildred used is known as _______
Radiocarbon dating
Faulting
Indexing
Superposition
Explanation:
Radiocarbon dating is a process of determining the age estimates of various objects and materials using the radioactive properties of an isotope of carbon, carbon-14.
Radiocarbon dating uses the ratio of two isotopes of carbon, carbon-12 and carbon-14 present in materials which contains carbon to determine their age.
There is a fairly constant ratio of carbon-12 and carbon-14 in living organisms. However, at death, due to the decay of carbon-14 to carbon-12, the ratio begins to change. Since the rate of decay of carbon-14 is fairly constant, a property known as half-life, the time it has taken for carbon-14 to decay to carbon-12 can be calculated. This calculated time will givee the age of the fossilised material.
according to criteria such as salinity, depth, and whether the water is flowing or standing
