Answer:
Human Activitys.
Explanation
The goods we use, travel around the world very quickly, and they often carry uninvited species with them.
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

The answer is <span>A. Decrease in genetic variation
</span><span>
A founder effect is a result of a geographical separation of a few individuals from the original population. Those few founding individuals will form a new population so they are founders. In this new population, there will be present alleles of the few founding individuals. However, those few founding individuals do not represent a whole genetic variation of the old population, but only some part of it.
Imagine a population of fish in which there are yellow, green, blue, and red colored fish. In the population, there is a genetic variation. But, if a few green-colored and red-colored fish geographically separate from the population and form a new population, in the new population there will be decreased genetic variation (because there are only green and red fish compared to the old population where are fish in 4 different colors).</span>
Answer:
CO2 increases the affinity of oxygen for hemoglobin so that hemoglobin binds oxygen more strongly
Explanation:
Hemoglobin (Hb) is a protein found in red blood cells that functions to transport oxygen (O2) to the tissues. This protein has four subunits and each subunit binds to a heme group. Each heme group in Hb contains an iron atom that binds to one O2 molecule. The affinity of hemoglobin for O2 is a critical mechanism that is dependent on the ability of Hb to carry O2 molecules. Hb is fully saturated with O2 when all of its four O2-binding sites are occupied. Moreoever, the O2-hemoglobin dissociation curve is a plot of saturation of Hb regarding the partial pressure of O2 (PO2). A rightward shift in the curve indicates that Hb has a decreased affinity for O2, while a leftward shift in the curve indicates that Hb has an increased affinity for O2. As CO2 concentration increases, hemoglobin's affinity for O2 decreases, thereby Hb binds to O2 less tightly at heme group sites and therefore the dissociation curve shifts to the right.
