Gabbro and basalt are two igneous rocks having the same chemical composition, and the same minerals (plagioclase feldspar + pyroxene), but are of different origins. Gabbros form at depths and cool slowly, whereas basalts are volcanic rocks that crystallize rapidly at the surface of the earth.
<span>The question above is incomplete, the remaining part of the question is given below:
1. Since more offspring are produced
than an environment can support, organisms within a population must compete for
resources to survive.
2. Due to variations within the population, some competitors will be better
equipped for survival than others.
3. The best-equipped organisms will survive and will produce well-equipped
offspring.
4. Variations that help with survival will be passed on to future generations
and will rapidly change the whole population.
Which point is flawed as written above?
A. point 1
B. point 2
C. point 3
D. point 4</span>
ANSWER
The correct option is D.
All the options written above about Darwin's theory are quite correct with the exception of option D. Charles Darwin was the scientist who proposed the theory of evolution by mean of natural selection. Darwin submitted that, due to the scarcity of needed resources in an environment, it is only the fittest individuals in a particular population that will be able to survive and produce offspring that share their adaptability features. As this continue from generation to generation, it leads to evolution, which is defined as the changes overtime, which give rise to new species that share a common ancestors. Contrary to the point made in option D, evolution by natural selection is not a rapid process at all, it is a process that occur over a long period of time.
Through looking at layers of rock you can tell what kind of things transpired. If you find Fish fossils you can assume that at one point in time, there may have been a body of water of some sort. if you find certain plants, you can deduce that there was a forest or a grassy pasture. Or if there are variations in the layer you may be able to tell what kind of soil was there at one point in time, or maybe if there is volcanic rock, you could rightly assume there was a volcanic eruption at some point.

Explanation:
Nucleotides are A & T and G&C you see in DNA and in RNA T is Replaced by U. The reason they must be balanced between G&C and T&A is because G has to bond with A in DNA and G with C so if there is more G than C that means there is mismatches between the DNA nucleotides same thing for A and T. In RNA you follow the same rule. If we have lets say 27% of our DNA as A we have to have 27% as T leaving 23% as C and 23% as G. If there was lets say 29% T while one 27% A then there was a error in DNA replication and could lead to errors in RNA synthesis if not corrected
