Chesapeake bay is an area that has suffered from overharvesting and eutrophication. Eutrophication is an enrichment of water by nutrients salts that causes structural changes in the ecosystem such as increased formation of algae and aquatic plants, depletion of fish species among other effects. The greatest source of nitrogen and phosphorus in a Chesapeake bay is agriculture
Explanation:
We breathe in oxygen and we breathe out Carbon dioxide the plants like trees flowers and other plants breathe in carbon dioxide and breathe out oxygen this is why we need to stop cutting down trees and tearing up flowers and all other types of plants
Answer:
Enzyme catalysis is detected by measuring either the appearance of product or disappearance of reactants. To measure something, you must be able to see it. Enzyme assays are tests developed to measure enzyme activity by measuring the change in concentration of a detectable substance.
<span>rate of technological progress. The steady-state growth rate of total output is equal to the rate of population growth (n) plus the rate of technological progress (g). A change in the rate of technological progress will permanently change the growth rate of total output. </span>
Purple white and lavendar four oclock flowers why did the four o'clock flower plant give three phenotypes instead 2 is a genotype that is 2:2 Rr and rr.
The 4'o clock plant, phenotypes , exhibits partial dominance in flower colour, which is why the F1 plant produced by crossing a pure Red flowered plant (RR) with a pure White flowered plant (rr) has pink flowers (Rr).When an F1 plant (Rr) crosses with a pure white flowering plant (rr), the resulting plant will have a genotype that is 2:2 Rr and rr.
The phenotypic, however, will be 2 pink and 2 white at a ratio of 2:2.
The offspring's phenotypic ratio will be 2:2.
