Answer:
Some animals weather rocks by scraping them as they feed. Other animals change Earth's surface by burrowing into it and moving material. Too many animals in one place can destroy most of the plants, leading to faster erosion.
If too many animals graze the same land area, the animals’ hooves pull plants out by their roots. A land is overgrazed if too many animals are living there. Grazing animals can cause erosion if they are allowed to overgraze and remove too much or all of the vegetation in a pasture.

The answer is B)
The Golgi apparatus is located in the cells. It is an extra combination of organelle similar to the ER. This was named following Camillo Golgi.
(Notice that his last name is Golgi)
Answer:
The population that existed before mining must have included both copper tolerant and copper intolerant
Explanation:
Natural selection is a form of evolution where individuals having a certain variation gives them an advantage at survival and reproduction compared to the ones that do not have the variation.
For natural selection to occur, the variation should initially be present in the population.
Therefore, for this population of Monkey flowers growing in a copper -contaminated soil. The population must have included both the copper tolerant and the copper intolerant plants before mining.
Answer: The genotype ratio is 2Ff : 2ff
The phenotype ratio is two normal feathered birds to two silky feathered birds.
Explanation: Let F represent the gene for normal feather and f represent the gene for silky feather. F is dominant while f is recessive, therefore a male that is hybrid for trait of normal feather is heterozygous and will have a genotype of Ff, a female that is homozygous for silky feather will have a genotype of ff.
A cross between Ff and ff will yield 2Ff birds and 2ff birds. Since F is dominant, a bird having genotype of Ff will manifest outwardly as blue feathered birds while ff will manifest outwardly as silky feathered birds because f is recessive and must occur in a homozygous condition in order to manifest phenotypically. Therefore, the genotype ratio is 2Ff: 2ff.
