LAMARCK's THEORY
Jean Baptiste Lamarck (1744-1829) proposed a theory which was published in "<em>Philosophie Zoologique"</em> (1809). This theory is simply known as Lamarckism. It has two main postulates:
1. Use and disuse of organs
2. Inheritance of acquired characters.
Example
He explained his theory by giving the examples:
1. Neck length of Girrafes
2. Webbed toes of water birds, and
3. Wings of penguins
Explanation
Lamarck explained that water birds use toe for swimming, with the passage of time webbed were developed in their toes. these features were then transferred to their offspring.
Drawback
Lamarck theory was based on natural observation. It did not explain the genetic basis of such characteristics.
The appropriate answer is b. turgor pressure. Turgor pressure is also known as hydrostatic pressure and is the force of the water inside the cell of the plant that pushes the cell membrane against the cell wall. When this force is strong the cell or the plant is said to be turgid. This pressure is maintained by the process of osmosis.
Plants react differently to the stimulus of light. They will grow or turn leaves towards light.
<span>If the earth tides are decreased, the explanation would likely be: the gravitational attraction decreases as the earth moved farther from the sun, thus, affecting the tide. On the other hand, if the gravitational pull increases, it would mean that the earth tide would also increase. Remember, the two major factors that influences earth tides are: gravitational pull of the moon and of course, the sun.</span>
