The flu vaccine changes every year. The flu vaccine is based on a predicted strain that is anticipated to be the most infectious that year. Thats why people who sometimes get the vaccination still get the flu, they don't have the antibodies for the strain they were infected with. Strains for viral disease don't change very much and usually the vaccination for them cover them well.

Movement and balance are monitored by activity in the cerebellum.
<h3>What is meant by the cerebellum?</h3>
The cerebellum, also known as the "little brain" because it resembles a miniature cerebrum, is in charge of balance, movement, and coordination. The pons and medulla, along with the midbrain, are commonly referred to as the brainstem. The brainstem receives, sends, and coordinates messages from the brain.
The cerebellum is the area of the brain in charge of coordinating voluntary movements. It is also in charge of a variety of functions, including motor skills like balance, coordination, and posture.
The cerebellum is important for maintaining balance by making postural adjustments. It modulates commands to motor neurons based on input from vestibular receptors and proprioceptors to compensate for changes in body position or muscle load.
Therefore, the correct answer is option B) cerebellum.

1Answer:
The correct answer is - D. how changes in biodiversity impact an ecosystem.
Explanation:
The water hyacinth is an invasive plant species that rapidly grows and creates a thick layer over the water surface in almost every aquatic ecosystem. The growth of the layer of this species causes problems to the environment, ecosystem, humans, and other species.
These aquatic plants reduce the oxygen level and other nutrients from the ecosystem it is introduced and affect the biodiversity by increasing heavy metals and contaminants.
The layer of this plant inhibits photosynthesis that decreases sugar and energy production and blocks the boat and ship movements and economically as well.
