Light-dependent reactions happen in the thylakoid membrane of the chloroplasts, while the Calvin cycle happens in the stroma. They occur when in the presence of sunlight. Hope this helps!
Answer:
Special Consideration Regarding Egg Allergy
People with egg allergies can receive any licensed, recommended age-appropriate influenza vaccine (IIV4, RIV4, or LAIV4) that is otherwise appropriate. People who have a history of severe egg allergy (those who have had any symptom other than hives after exposure to egg) should be vaccinated in a medical setting, supervised by a health care provider who is able to recognize and manage severe allergic reactions. Two completely egg-free (ovalbumin-free) flu vaccine options are available: quadrivalent recombinant vaccine and quadrivalent cell-based vaccine.
Get vaccinated before flu season starts

It takes about two weeks after vaccination for antibodies that protect against flu to develop in the body.
September and October are generally good times to be vaccinated against flu. Ideally, everyone should be vaccinated by the end of October. Additional considerations concerning the timing of vaccination for certain groups include:
Adults, especially those 65 years and older, should generally not get vaccinated early (in July or August) because protection may decrease over time, but early vaccination can be considered for any person who is unable to return at a later time to be vaccinated.
Children can get vaccinated as soon as vaccine becomes available, even if this is in July or August. Some children need two doses of flu vaccine. For those children it is recommended to get the first dose as soon as vaccine is available, because the second dose needs to given at least 4 weeks after the first.
Early vaccination can also be considered for people who are in the third trimester of pregnancy, because this can help protect their infants during the first months of life (when they are too young to be vaccinated).

Answer:
The correct answers are:
Analogous structures do not indicate a common ancestor. Analogous structures have the same function but a different structure. An example of an analogous structure is the wing of a bat and a butterfly.
Explanation:
Analogous structures are the structures that have a similar function in various organisms but their anatomic structure is different from one another in reality. Analogous structures are do not indicate a common ancestor.
An analogous structures example is the wings of the bat and butterfly as they are both used for flying but their structure is different anatomically from one another.
