A, c, and d. the early plant would still have small roots but would not have a vascular system completely built
Answer:
a. The molecule is not lipid soluble b. The molecule is not derived from a series of steps beginning with cholesterol
Explanation:
All the steroid hormones have a four ring sterol nucleus in their structure. These hormones are soluble in lipids. Steroid hormones are produced by the pathways using cholesterol as the starting substance. Some of the examples of steroid hormones are aldosterone, calcitriol, estrogens, and progesterone. Therefore, if the given molecule is not soluble in lipids and is not derived from cholesterol, it cannot be a steroid hormone.
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).
Explanation:
Answer: The correct option in blank is anion.
Explanation: Ionic compound is formed by the transfer of electron from one atom to another atom. When an electropositve atom lose an electron it form cation, whereas as anion is formed when an atom gain an electron. These actions and anions then attract each other and form an ionic compound.
I hope it will help you.
Example: The formation of NaCl is best example of ionic compound. Na has one electron in its outer most shell which can easily be removed to form Na+, while Cl has seven electron in its outer most shell so it can easily gain an electron lost by Na to form Cl-. Then these ions attract each other and form NaCl as shown in the figure.
