Which of the following choices would be the most logical third step in Connell's experimental procedure, permitting him to eithe
r accept or reject his hypothesis of competitive exclusion? The experimental group:________
a. The half of each rock that contained both Balanus and Chthamalus was the experimental group.
b. The experimental group tests to see if the presence of Balanus in some manner prevents Chthamalus from growing.
Answer: B) The experimental group tests to see if the presence of Balanus in some manner prevents Chthamalus from growing.
Explanation:
The most logical third step in Connell's experimental procedure, permitting him to either accept or reject his hypothesis of competitive exclusion is the experimental group tests to see if the presence of Balanus in some manner prevents Chthamalus from growing.
Balanus is a species of crustacean, as know as sea acorns, whereas Chthamalus is a species of barnacles that can easily be found in the northern hemisphere's coasts.
The theory of evolution that states that groups of organisms change over time. In essence, a current population of kangaroos is a product of several changes that have occurred over millions of years, resulting in the kangaroos we currently see.He's perhaps the most famous evolutionary scientist. He published his theory of evolution by natural selection in 1859
Darwin knew a mechanism was behind the change, or evolution, that had occurred, creating different beaks. He called this mechanism natural selection. Darwin proposed that over time, a population of finches could develop different beak shapes in order to best eat whatever food was most available to them, thus allowing them to survive better
He used the term 'survival of the fittest' as a short hand for organisms so well-suited to their environment that they will live long enough to reproduce, passing their traits, like beak shape or eye color, to the next generation
Hence, the right answer is "Organisms within a population vary, and all populations produce more offspring than can be supported by the environment, resulting in competition for survival within the population"
The correct answer would be letter B, A covalent bond also known as, molecular bond is a chemical bond sharing two electrons or sharing bonds between atoms.
