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.
Answer: a crack forms, magma pushes upward, rock moves outward, magma hardens.
I know this 100% fact
Explanation:
C. Flowers are bigger than spores, and there is sexual reproduction in plants with flowers.
Fungi during their life cycle have a haploid phase.
Also have a diploid phase.
Human somatic cells are diploid. (Blood, skin, Muscles, even zygote)
Human sex cells are haploid. (Eggs and sperms)
Hope this helps.
When a pollutant is removed from the air by a natural process, it ends up somewhere else.
