Adenine to thymine and cytosine to guanine are the base pairings during DNA replication.
Answer:
a
Explanation:
Connective tissue often consists of relatively few cells embedded in an extracellular matrix.
Answer:
We will produce lactate/lactic acid through fermentation.
Explanation:
During strenuous activities, muscle cells do not sufficient supply of oxygen to meet the energy requirements. As a result, anaerobic respiration occurs to temporarily supply energy and lactic acid is produced instead of carbondioxide and water.
Lactic acid accumulates in muscles and eventually preventing further contraction. The muscle cells are said to have incurred an 'oxygen dept' since they have used up more energy than was possible from the oxygen supplied to them. The largest amount of lactic acid a body of a trained athlete can tolerate is about 127grams, and the largest tolerable oxygen is about 16 litres.
It’s stored energy yk you could of just looked it up
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.
