<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.

Limestone formations in caves are considered what kind of weathering
madreJ [45]

Answer:

Chemical weathering

Explanation:

Caves are formed by the dissolution of limestone. Rainwater picks up carbon dioxide from the air and as it percolates through the soil, which turns into a weak acid. This slowly dissolves out the limestone along the joints, bedding planes and fractures, some of which become enlarged enough to form caves.

Chemical weathering involves the decomposition of rocks due to chemical reactions between minerals such as calcite with water and gases in the atmosphere (e.g. carbon dioxide and sulphur dioxide). The solution of soluble minerals is particularly important in limestone landscapes.

Solutional caves or karst caves are the most frequently occurring caves. Such caves form in rock that is soluble; most occur in limestone, but they can also form in other rocks including chalk, dolomite, marble, salt, and gypsum.

Essentially, water reacts with carbon-dioxide to form carbonic acid. It then seeps slowly through the roof of the cave, depositing calcium carbonate, which hardens and builds up over time to form a stalactite.

How do the characteristics of shale change with increased pressure and temperature?
dalvyx [7]

Answer: Shale changes into Slate.

Explanation:

Shale is a sedimentary rock, formed by the deposition and compression of clay and silt.

Shale layers is buried deep into the earth through the process of deposition (i.e the laying down of rock forming material by natural entities like glaciers, wind, and water).

Temperatures and pressures rise greatly because the shale’s layers are buried. When the temperatures and pressures become higher. The shale is changed into a metamorphic rock (with dark brown streak), called Slate.
