Tape worms have numerous adaptations to enhance their survival in the hosts.
For example the have anatomical adaptations in the form of scolex with hooks that they use to attach to the host small intestine walls therefore preventing them from being excreted following peristalsis. Therefore, the correct answer is that they posses hooks that they use to attach to the small intestines.
Explanation:
Temprature:the body must maintain a relatively constant temperature if it gets to hot the body employees vasodilation to cool down this delites the blood vessels allowing more heat to escape from them through the skin
Glucose: the body must regulate glucose levels to stay healthy. When glucose levels become to high the body realeases a hormone called an insulinwhen they become to low the body converts the glocogenin the blood to glucose
Toxins :in the blood can distrupt the body's homeostasis thus it signals the urinary system to ensure that the toxins are excreated
The answer is (A. mitosis)
The basic repeating unit of nucleic acids are known as nucleotides. A nucleotide consists of three distinct chemical groups, a 5-carbon sugar (ribose or deoxyribose), a nitrogen-rich base - (cytosine (C), guanine (G), adenine (A), thymine (T) in DNA or uracil (U) instead of T (in RNA), and phosphate.
There is no answer that is right except for C. Natural Selection.
Genetic Recombination doesn't change gene frequency;nor does migration. (Unless it's local)
Mutation could be the answer, but since mutations are too rare to really power Evolution, the only logical answer is Natural Selection.
