The leading cause of death is Suicide. An odd answer but that's what it says.
The correct answer is memory cells.
Vaccination refers to the clinical use of immunization established to artificially assist the body in fighting against the disease. A vaccine against an infection is an amended kind of a natural immunogen that may be the component of the pathogen, a toxin, or even the whole pathogen.
A vaccine does not result in a disease, however, instigates the healthy host to fight against the epitopes of the amended immunogen and produce ample amount of memory cells (T and B cells).
Due to the production of the memory cells, when the body comes in contact with an antigen or immunogen again, then the memory cells generate antibodies quickly and kills the pathogen before it can impart its influence.
Answer: A neuron has three main parts: dendrites, an axon, and a cell body or soma , which can be represented as the branches, roots and trunk of a tree, respectively. A dendrite (tree branch) is where a neuron receives input from other cells. Dendrites branch as they move towards their tips, just like tree branches do, and they even have leaf-like structures on them called spines.
The axon (tree roots) is the output structure of the neuron; when a neuron wants to talk to another neuron, it sends an electrical message called an action potential throughout the entire axon.
The features of neurons help them to carry out their function efficiently:
they have a long fibre (axon) so they can carry messages up and down the body over long distances
in a stimulated neuron, an electrical nerve impulse passes along the axon
the axon is insulated by a fatty (myelin) sheath - the fatty sheath increases the speed of the nerve impulses along the neuron
at each end of the neuron are tiny branches (dendrons), which branch even further into dendrites - the dendrites receive incoming nerve impulses from other neurons

Answer:
B. The vacuole is not full and the plant is wilted
Explanation:
When a plant cell is placed in a hypertonic solution, the water inside the cells is drawn out by osmosis. The vacuoles decrease in size. The cytoplasm also shrinks away from the cellulose cell wall and plasmolysis occurs. This causes a lack of structure for the plant and causes it to wilt, or become flaccid.
The correct answer is trophic level.
Feeding relationship of different organisms in which one is being eaten by other is called food chain. Each group of organisms in a food chain is called trophic level. Green plants are producers which make their food with the help of sun energy is included in one trophic level. Similarly plant eaters or herbivores are primary consumers and those animals which feed on primary consumers are secondary or tertiary or top consumers are other trophic levels.
