Answer:
When a potato chip is put into salt water, the potato cells become flaccid (soft and floppy). This is because there is a higher concentration of water molecules inside the potato cells than outside. If more water enters the cell, it becomes turgid. This is important in supporting plants.

Answer:
four phenotypes appear in the ratio 9:3:3:1
Explanation:
<em>For a dihybrid cross in which the two genes concerned obey simple dominant/recessive law and are independently assorting, </em><em>four phenotypes are produced in the ratio 9:3:3:1. </em>
The dominant gene takes up the largest ratio (9/16) while the recessive gene takes up the smallest (1/16). Any deviation from 9:3:3:1 and the number of phenotypes produced from a dihybrid cross is an indication that the genes involved do not obey Mendelian laws.
Taenia saginata/Taenia solium are commonly known as tapeworms is a <u>true</u> statement.
Explanation:
Tapeworms are long segmented parasitic flatworms which reside in the intestines of the host’s body. They belong to the phylum Platyhelminthes and scientifically called the Cestoda.
Tapeworm belonging to the Taenia species like the T. saginta, T. solium, T. asiatica etc causes parasitic infections called Taeniasis in the human body and affects the intestines.
Taenia saginata is the tapeworm which resides in pork and Taenia soleum resides in beef.
Humans can be infected with tapeworms when raw or improperly cooked pork or beef is consumed
