The Gulf of Mexico dead zone is an area of hypoxic waters at the mouth of the Mississippi River. Its area varies in size, but ca

n cover up to 6,000-7,000 square miles. The zone occurs between the inner and mid-continental shelf in the northern Gulf of Mexico, beginning at the Mississippi River delta and extending westward to the upper Texas coast. Thousands of farms are located along the Mississippi River and its tributaries and as water washes into the river after a heavy rain, it brings with it nutrients from fertilizers added to farmland. These materials flow downriver and eventually enter the Gulf of Mexico, where they create conditions for a dead zone: an area of low to no oxygen that results in the death of fish and other marine life. The Gulf of Mexico is a major source area for the seafood industry. The Gulf supplies 72% of U.S. harvested shrimp, 66% of harvested oysters, and 16% of commercial fish. Consequently, if the hypoxic zone continues or worsens, fishermen and coastal state economies will be greatly impacted. What can be done to minimize the Gulf dead zone? Choose ALL that could apply. A) Control of animal wastes so that they are not allowed to enter into waterways. B) Adjust the timing of fertilizer applications to limit runoff of excess nutrients from farmland. C) Monitor septic systems and sewage treatment facilities to reduce discharge of nutrients to surface water and groundwater. D) Restrict land use in the areas surrounding the Mississippi delta to exclude industrial sites. E) Counter the effects of fertilizers on algal growth in the Gulf with the use of chemical herbicides.

Please choose the answer. This is a multiple choice.
Rama09 [41]

Answer:

Some individuals have genes that increase their chances for survival and reproduction. These individuals are more likely to reproduce and pass on their genes, causing their genes to become more common in the next generation.

Explanation:

The basic idea of ​​natural selection is that environmental conditions determine how well the characteristics of organisms contribute to the survival and reproduction of the organism; organisms that do not have these traits may die before reproduction or be less fertile. As long as environmental conditions remain the same or close enough for these traits to remain adaptive, these traits will become more common in populations. The loss of an ecological niche of a species or overcrowding as a result of an increase in abundance can significantly alter the adaptive characteristics required for survival. In this case, and also in any environment where survival is determined more by ecology than secondary sex characteristics, ecological choice takes place.

How many covalent bonds would you expect a neutral carbon atom to form in an organic compound?
hoa [83]
The number of covalent bond an element can form depends on the number of electrons it has in its outermost shell (valence electrons). Carbon has four valence electrons, therefore, it can form maximum of four covalent bonds in an organic compound.
