How might the destruction of rainforests affect the balance of gases in Earth's atmosphere?
by increasing carbon dioxide and decreasing oxygen
by increasing carbon dioxide and increasing oxygen
by decreasing carbon dioxide and increasing oxygen
by decreasing carbon dioxide and decreasing oxygen
The answer to this question is by increasing carbon dioxide and decreasing oxygen.
Explanation:
Rainforests have a vital role on Earth because these regulate the levels of oxygen vs carbon dioxide. This is because plants including trees, grasses, shrubs, etc. require carbon dioxide as part of the photosynthesis process, and they release oxygen at the end of the process. In this way, rainforests reduce the amount of carbon dioxide and increase oxygen.
In this context, deforestation or the destruction of rainforest for mining, roads, etc. implies there are fewer plants, and therefore, less carbon dioxide is being used and less oxygen is released. This causes an increase in carbon dioxide and a decrease in oxygen.

A- All cells contain a nucleus.
B- Cells are the basic unit of structure and function in an organism.
C- All living things are made of cells.
D- New cells are produced from existing cells.
3.
When using a light microscope to view a cell she obtained from scraping under her fingernails, Mrs. Smith notices that the cell lacks a nucleus; therefore, Mrs. Smith concludes that the cell must be a type of _____ cell.
A- Animal
B- Plant
C- Eukaryotic
D- Prokaryotic
4.

B- Animal cells, but not plant cells
C- Both plant cells and animal cells
D- Neither plant cells nor animal cells
5.

B- Ribosomes
C- Nuclei
D- Mitochondria
1. C
2. C
3. D
4. C
5. B
B. cnidarian
C. arthropod
D. roundworm
The correct answer is option D, Round worm
Roundworm belongs to the phylum Nematodes and some common characteristics of Nematodes are – they are small, slender , un-segmented, smooth and shiny. Roundworm has a round body just like a spiny –headed worm which do not have segments . Also they possess a body cavity known as pseudocoel in which the internal body organs lie and the body cavity is not lined with mesodermal cells.
