A pure substance is any substance on its own. For example, sand is impure for containing lots of different substances. However, diamonds are mostly pure for only containing one type of substance.
Whether a substance is pure or not doesn't relate to a substance's molecular structure, but different molecules in a substance. Water by itself is only H2O, therefore it still pure.
Water is not an element but a compound for containing different elements, however it still pure.
Reproductive success will increase, because there will be more females to lay eggs.
Reproductive success will decrease, because there will be skewed numbers of males and females.
Reproductive success will decrease, because there will be longer migration routes due to sea level rises.
Answer:
The correct answer would be Reproductive success will decrease, because there will be skewed numbers of males and females.
Explanation:
Sea turtles incubate their eggs in the sand at nesting beaches. In cooler temperatures produce more males, and warmer temperatures produce more females.
If the temperature rise will be in the climate then there will be fewer males in comparison to the females which can lead to a decrease in reproductive success. If there will be a fall in temperature than there will be fewer females in comparison to males which also led to a decrease in reproduction success.
Thus, the correct answer is the third statement.
The prairie grass in this ecosystem is the primary producer, which stores most of the energy in this ecosystem to provide this energy to all other organisms, hence option B is correct.
In this ecosystem, there is a continuous flow of energy due to the interaction of the biotic and abiotic factors, this ecosystem includes prairie dogs, coyotes, vultures, and prairie grass.
The primary producer of this ecosystem prairie grass is an autotroph by using the process of photosynthesis, they used make their own food having more amount of energy other than any tropic level.
All the organism in the ecosystem depends on the primary producer for their energy need, so indirectly on the sun.
Therefore, prairie grass in this ecosystem provides energy to all other organisms in this ecosystem.

b. pulmonary artery.
c. aorta.
d. vena cava.
Answer:
Antigen
Explanation:
b. It was successful.
c. It explained his theory of evolution.
d. It was based on his findings in South Africa.
It was based on his findings in South Africa; is not true Darwin’s book On the Origin of Species
The theory on " Charles Darwin's book "On the Origin of Species" stated that:
" individuals with traits that enable them to adapt to their environments will help them survive and have more offspring, which will inherit those traits"
Evolution simply means the way or process by which different kinds of living things were believed to have originated or developed from earlier forms

Answer:
The correct answer is option D.
Explanation:
Darwin's book on the origin of species explains his theory of evolution and he was working on this book's manuscript over three years time period. The origin of species is well known and was very successful. So, all three statement are correct.
The book was based on findings on Galapagos island and South America not in south africa. This book explained natural selection on the survival of the fittest theory.
Thus, the correct answer is option D.
