Answer the following statement(s) true (T) or false (F)

Question

1.Onebasic characteristic of living matter is that it is in chemical equilibrium; that is, it is in a stable, balancedcondition with reciprocal reactions going on.
2.One of the central tenets of Charles Darwin’s theory was that some variants prove to be better adapted to, or fitter for, their particular environment; hence, they get more resources and have more offspring.
3.The idea of spontaneous generation posited that new life could emerge suddenly from the decayed remnants of old life
4. The simplest living cell, without a nucleus, is called a eukaryote.
5.Nearly half of all fossils found in the world are those of dinosaurs.

Answer 1

1.False
Explanation: Onebasic characteristic of living matter is that chemically it isnot in equilibrium; that is, it is not in a stable, balancedcondition with reciprocal reactions going on.Instead, in living cells energy flows take place as membranes let somechemicals in and keep others out.
2.True
Explanation: One of the central tenets of Charles Darwin’s theory was that some variants prove to be better adapted to, or fitter for, their particular environment; hence, they get more resources and have more offspring.
3.True
Explanation: Even up to the mid-nineteenth century, naturalists clung to an old idea called spontaneous generation. It posited that new life could emerge suddenly and spontaneously from the decayed remnants of old life.
4.False
Explanation: The simplest living cell is called a prokaryote (pro-CARRY-oat), which means a cell without a nucleus.
5.False
Explanation: Nearly half of all fossils found in the world are those oftrilobites, an early group of invertebrates widespread some500 million years ago. They appear suddenly in the fossilrecord with no trace of earlier forms and disappear ina mass extinction of 75 to 95 percent of species that occurred about 242 million years ago. Modern lobsters and horseshoe crabs areamong their descendants.
