Answer:
2 (tall) :2 (short) or 1:1.
Explanation:
Mendel is known as the father of genetics. He explains the laws of segregation and the laws of independent assortment by working on the pea plant <em>Pisum sativum.</em>
The height of tall pea plant be T and the short pea plant be t. The cross between heterozygous dominant tall pea plant (Tt ) and short pea plant (tt) is as follows:
Parents Tt × tt
The progeny obtained from the cross are Tt, tt, Tt and tt.
Two tall pea plants and two short pea plants.
Thus, the phenotype ratio is 1:1.
The both have 8 arms, the squid has an extra 2 tentacles though.
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.
Some scientists believe it was due to a sudden meteor impacts and others believe it was a gradual build up of a couple things like volcanic activity, climate change and the meteor impact was the final blow for total destruction.
The answer is B) ATP production begins with glucose.
