Answer:

live attenuated vaccine

Explanation:

The correct answer would be a <u>live attenuated vaccine.</u>

<em>Vaccines are made from weakened/inactivated pathogens or their toxins and when they are administered to the body, they stimulate the body's immune system to produce antibodies that tend to persist and tackle any future invasion of the body by the pathogen.</em>

Vaccines can be an inactivated ones if they are made from inactivated pathogens, <u>they can be live attenuated if they are made from a weakened or attenuated version of the pathogen</u>, or toxoid vaccine if they are made from toxins of the pathogen. Other forms of vaccines include mRNA vaccines, conjugate vaccines, and viral vector vaccines.

What two substances are we concerned about over-nourishing our water sources and ultimately leading to eutrophication?
expeople1 [14]

The correct answer is - nitrogen and phosphorus.

The nitrogen and the phosphorus are the two substances that cause most of the eutrophication. It is good for the organisms that live in the water when these two substances are available as they are very important nutrients, but if the optimal amount is surpassed than it can be devastating. When there's high quantities of nitrogen and phosphorus in the water it makes it much more rich in nutrients that it should be. That kind of situation is the best for the algae, which start growing all over the place, quickly covering the water and becoming the dominant life form. As that happens, the organisms that use photosynthesis will die out because the Sun will be blocked, and the algae  will also contribute to a big reduction of the oxygen in the water too. The end result being totally destroyed ecosystem that has been overtaken by algae.

Yanka [14]

Plant A would have one allele from each parent, so the leaf color will be the dominant one.

Plant B would have a more complex percentage for traits. And it'll probably "cancel-out" some alleles only showing the info given in one of them.



Hope it helped,
