Scientists have yet to prove that the current global warming trend is not part of the natural cycle of Earth. Many things are being done now, mostly focusing on emission controls placed upon industry and transportation.
Answer:
The five true statements are numbers: 1, 2, 5, 6 and 7
Explanation:
1. Temperature drives water movement in some lakes.
2. Tropical coral reefs generally exist in relatively shallow areas of the ocean.
5. Wetlands have slow water movement or no water movement and no turnover.
6. Estuaries are very productive and are used as breeding grounds by many species of fish.
7. A freshwater organism permanently attached to the substrate would be unlikely to survive and reproduce in an estuary.
I'd say false...
good luck!
This should be True
Seafood Watch has had an immense influence on decisions regarding illegal fishing practices and has helped design sustainable seafood environments due to their lists of seafood that should be eaten without worries.
-The number of B cells producing the antibody is proportional to the concentration of that antibody.
-On day 16, one out of 100000 B cells are specific for antigen A
\frac{1}{100000} = 1 x 10⁻⁵ B cells
- on day 16, Antibody concentration is 2 × 10¹= 20 Antibodies
- on day 36, antibody concentration 8 × 10³.= 8000
20 antibodies ------------ 1 x 10⁻⁵ B cells
8000 antibodies--------------x
x= (8000 x 1 x 10⁻⁵)/ 20
x= 4x10⁻³ or 1 in 250 are <span>B cells specific for antigen A</span>
