Monarch caterpillars feed on all the different parts of milkweed plants and store up the toxins in their body. The toxins remain in their system even after metamorphosis, thereby making adult monarchs poisonous as well. Adult monarchs feed on nectar from a wide range of flowers, including milkweeds.
What is an 'Operating Expense'. An operating expense is an expense a business incurs through its normal business operations. Often abbreviated as OPEX, operating expenses include rent, equipment, inventory costs, marketing, payroll, insurance and funds allocated toward research and development.
Travel expenses defined. For tax purposes, travel expenses are the ordinary and necessary expenses of traveling away from home for your business, profession, or job. An ordinary expense is one that is common and accepted in your trade or business. A necessary expense is one that is helpful and appropriate for your business. An expense does not have to be required to be considered necessary. You will find examples of deductible travel expenses in Table 1-1 , later.
