Because roundworms move around more quicker than flatworms
Answer: b) organelles must interact with each other to synthesize and transport proteins.
Explanation:
The DNA is a genetic material which is converted into mRNA by the process of transcription in the nucleus. The protein synthesis takes place in ribosomes where the translation of mRNA to protein takes place. The proteins are transferred to rough endoplasmic reticulum for the packaging into membrane structures called as cisternae. The proteins are transferred to the golgi apparatus where they are modified, sorted and packed in vesicles. The vesicles take away proteins outside the cell. In golgi apparatus the proteins are tagged with the aminoacids so that they can be targeted to the particular cell.
The outer layer of the skin is called the epidermis. This layer is formed by epithelial cells. The dead layer of cells is called the stratum corneum.
Because there is insufficient evidence to support the idea that all chimpanzees use tools. the scientist would need lots of hard evidence supporting this conclusion (lots of chimpanzees using tools)
