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.
Sexual reproduction is a form of reproduction where two gametes fuse together. Each gamete contains half the number of chromosomes of normal cells. They are created by a specialized type of cell division, which only occurs in eukaryotic cells, known as meiosis.
So i'm gonna say that the answer is..B. helped maintain a slow rate of evolutionary change.
The bear, even though it is a very heavy and bulky animal, it can run pretty fast, and can easily outrun a human, but this is while running straight or when making gradual turns. The situation changes if the human starts running in a zigzag pattern. The human is much lighter, quick acceleration, long thin legs, and is much more agile, which will all be its advantage because in this kind of a chase the agility and acceleration are crucial. The bear on the other hand, will find it very difficult because its weight will disable it to make quick turns, it has a slow acceleration, and is not agile. So a human with a solid amount of stamina with using this tactic has a pretty good chances of escaping a charging bear.
