In general, bitmap image formats are better suited for use on the web. However, one vector format that works well on the web is SVG (Scalable Vector Graphics)

The vector format that is best suited to use on the web is SVG (Scalable Vector Graphics). While raster formats like JPEG, GIF, and PNG are commonly used for images on the web due to their pixel-based nature, SVG is specifically designed for use on the Internet. Vector images, such as those in SVG format, store information about shapes and colors as mathematical formulas, allowing them to be scaled to different sizes without any degradation in quality. This contrasts with raster images that lose quality when scaled beyond their original dimensions.

Janice is unsure about her future career path. She has grown up on her family farm, but she is also interested in medicine. Janice becomes a member of the FFA and SkillsUSA to try to learn more about the fields and decide between them. What would be more helpful to Janice?
not joining SkillsUSA and joining HOSA instead
not joining SkillsUSA and joining BPA instead
not joining FFA and joining BPA instead
not joining FFA and joining HOSA instead

Answers

(D):  Not joining FFA and joining HOSA instead.

My best advice to Janice is to choose one over the other by joining HOSA instead of FFA or choose to use both. If her idea is to choose Medicine over farming, then HOSA is the way to go. HOSA is an available component that prepares students for a health career path and offer programs in health occupations and health sciences. It helps its members build self-confidence; develop effective leadership and strengthen their technical and academic skills.

However, as mentioned before, she can decide to use her background in farming while learning more about medicine. This will act as an advantage since she can have a strong understanding in medicinal farming. Example, she can learn ways to create effective drugs from plants.
