Answer:
C: they threaten biodiversity.
They don`t always pollute because they just eat or destroy things in the environment. (Thus "invasive")
Not all are predators. My state has an invasive form or blue reed river algae that kills fish.
Being nonrenewable is mostly irrelevant to the environment.
Hope that helps.
The two phases meiosis is divided into is Meiosis I and Meiosis II. Because Meiosis is not asexual reproduction is uses sexual reproduction by combining the chromosomes of the mother and father. Since each parent give 23 chromosomes to make the whole 46 a human needs, when the chromosomes come together they create tetrads. these are pairs of replicated chromosomes. There are 2 phases because the first phase separates the tetrads leaving the two sister chromatids. During Meiosis II, the sister chromatids are separated like in Mitosis. Overall, the reason that there are two phases is because the maternal and paternal gametes give replicated chromosomes to the zygote.
1. Centrioles can be correctly matched with F, that is, produce the spindle fibers for cell division.
2. Nucleolus can be correctly matched with G, that is, produce r-RNA to make ribosomes.
3. Nucleus can be correctly matched with B, that is, round structure within the cell.
4. Endoplasmic reticulum can be correctly matched with E, that is, channel through which molecules move in cytoplasm.
5. Golgi bodies can be correctly matched with D, that is, produce and package cell secretions.
6. Ribosomes can be correctly matched with A, that is, tiny structures which synthesize proteins.
7. Chromosomes can be correctly matched with C, that is, contain genes with the information controlling cell.
Answer: In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. ... Animal cells simply have a cell membrane, but no cell wall.
