Answer
Lamarckism, a theory of evolution based on the principle that physical changes in organisms during their lifetime—such as greater development of an organ or a part through increased use—could be transmitted to their offspring.
Lamarck believed that the stretching elongated the giraffe's neck, which became a useful characteristic and was passed onto future generations. This resulted in the length of the giraffe's neck increasing over time. It is now commonly accepted that Lamarck's ideas were wrong.
The product of glycolysis is (B.)
Answer:
Growth of cell and replication of DNA.
Explanation:
The cell cycle has three stages, the interphase, mitosis, and the G0 phase.
Interphase is before mitosis, and it prepares the cell for its division. Interphase has three phases:
- G1, where the cell grows in size due to the growth of organelles and components, which the cell will need later.
- In the S phase, the cell synthesizes a copy of the DNA.
- The G2, where the cell keeps growing and producing organelles and other elements that will need for mitosis.
In conclusion, in the interphase, the cell grows and replicates its DNA.
The correct option is B.
The alimentary canal is the pathway through which ingested foods move from the mouth all through into the anus. At each portion of the canal, different types of chemical reactions take place, which digest the eaten food and prepare the useful part for absorption and the waste part for excretion. In the alimentary canal, the stomach open into the small intestines. The small intestines is the site where the useful part of the nutrients will be absorbed into the system through villi.
