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.
Answer:
Cell-mediated immunity develops through a network of interactions that results in defense against microorganisms that survive within phagocytes or other cells. The response is initiated by the recognition of intracellular microorganism antigen by T cells through the histocompatibility complex. In the CD8 response, only the target cell carrying the class I associated antigen can be lysed or induced to apoptosis. In another mechanism of the cellular response, CD4 + Th1 T cells activate, for example, cytokine-infected macrophages such as IFN. When a pathogen resists the effects of activated macrophages, chronic infection may develop.
The hormonal immunity response leads to the destruction of extracellular microorganisms and prevents or decreases the spread of intracellular cells by neutralizing, opsonizing and activating the complement system.
The emergence of resistance is a result of EVOLUTION by natural selection. It is a major evolutionary force.
<h3>Evolution and natural selection </h3>
The term evolution refers to the biological process of descendence with modification.
Natural selection refers to the differential survival or reproduction of the organisms better adapted to a given environment.
In this case, the presence of the pesticide generates an evolutionary constraint, thereby selecting pesticide-resistant individuals in the population.

The answer of the question is citric acid cycle
Answer:
The correct answer will be - the sugar is not transported to roots
Explanation:
The girdling is performed on tress by making a groove of 1 cm in the bark of a tree.
The girdling activity removes the phloem tissue of the trees which help in the conduction of the sugar and other useful nutrients in the trees.
Since the phloem is present on the outside portion of the vascular cambium due to the secondary growth, therefore, removing the bark and making a groove in the tree removes the portion of the phloem. The removal of the phloem stops the blockage of the sugar to the roots as a result of which the root dies and water is not absorbed. This leads to the death of the tree after some time.
Thus, the sugar is not transported to roots is the correct answer.
