Answer:
If there is low genetic diversity, she needs to introduce something into the system to increase the variation. I would suggest breeding the orange trees with other new orange trees to change the allele frequencies, which is called gene flow.
Likely the fungi are attacking them somewhere that they have decreased resistance, and if more alleles were introduced, there would probably be evolution towards a genotype that promotes defense against these fungi.
The answer would be B. Atom, star, galaxy, universe.
Explanation: atoms are small cells that make up everything in existence. They're too small to be seen by the naked human eye. Stars are big balls of gas that can be seen at night in the sky. These are second biggest because you can see these with the naked eye, but galaxies you can not. The galaxy holds the earth, all of the other planets, stars, and other things. If the galaxy can hold all of that then clearly it would be bigger than the stars. The universe is what holds our galaxy. There are millions of other galaxies out there in the universe. Ours is just a small one of an infinite number.
I guess I would say b or d. Because concluded results change over time with better technology and some solutions dont work.
Answer:
I think its photosynthesis because its converts carbon dioxide. Also some plants use it too.
Explanation:
17.
decreases.
it substantially increases then decreases.
18.
to the same organisms because oak leaves come from oak trees.
19.
Pyramid B
Pyramid A does not accurately represent the supply of food for the caterpillars.
