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 can 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.
The things that should be done to minimize the Gulf dead zone include:
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.E. Counter the effects of fertilizers on algal growth in the Gulf with the use of chemical herbicides.It should be noted that it's important to manage nutrients efficiently in farmlands through the restoration of wetlands in order to capture nutrients and then reduce runoff.
In order to minimize the Gulf dead zone, there should be control of animal wastes so that they are not allowed to enter into waterways. Also, there should be an adjustment of the timing of fertilizer applications to limit runoff of excess nutrients from farmland.

Energy Efficiency =
Useful Energy Output/Total Energy
Input x 100 (%)
If a power plant uses 100 units of
energy to create electricity and the
output is 5 units, where does the
95% of the energy input go?
A. lost as heat
B. lost as gas
C. escapes the system as potential energy
If a power plant uses 100 units of energy to create electricity and the output is 5 units, 95% of the energy input goes as lost as heat.
Could you ever create a machine where 100% of the input energy would turn into output energy?No, a real machine can't have an efficiency of 100%. An efficiency of 100% means that there is no loss and the output energy (or work) of the machine is equal to input energy (or work). In real machines, there is always some loss of energy to overcome friction and air resistance.
How do you calculate the energy efficiency of a power plant?To express the efficiency of a generator or power plant as a percentage, divide the equivalent Btu content of a kWh of electricity (3,412 Btu) by the heat rate. For example, if the heat rate is 10,500 Btu, the efficiency is 33%. If the heat rate is 7,500 Btu, the efficiency is 45%.

Natural selection leads to adaptations to __________ in an organism's environment. View Available Hint(s) Hint 1.opened hint Consider the features of the environment that affect organisms' existence. Natural selection leads to adaptations to __________ in an organism's environment. nonliving factors such as temperature and chemicals other living organisms abiotic and biotic factors water for aquatic organisms and the atmosphere for terrestrial organisms
Answer:
abiotic and biotic factors
Explanation:
According to the evolutionary theory proposed by Darwin, natural selection can be defined as the mechanism by which evolution occurs (i.e., the mechanism by which species change over time). An organism´s environment is comprised of abiotic (e.g., temperature, light, water, etc) and biotic (e.g., microbes, food availability, etc) factors. Adaptations refer to the phenotypic traits that increase the chance of survival and reproduction of an organism in its environment. Organisms better adapted to their environment are selected by natural selection to reproduce and thus perpetuate their genes across generations.
(c) Based on the data, describe the time period during which Chlorella approximates exponential growth. Based on
the data and assuming logistic growth, describe the time period during which the Chlorella population has reached
the carrying capacity of the culture. Based the data, calculate the growth rate per day for the 5-day period with
the greatest growth rate.
Populations that experience a logistic growth model depend on the density and available resources. A) 5 - 10 days. B) 25 - 30 days. C) 0.27 x 10⁶cells/mL/day
What is the logistic growth model?In a logistic growth model, the population growth depends on density. Natality and mortality depend on the population size, meaning that there is no independence between population growth and population density.
When a population grows in a limited space, density rises gradually and eventually affects the multiplication rate. The population per capita growth rate decreases as population size increases.
The population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.
K is a constant that equals population size at the equilibrium point, in which the natality and the mortality rate get qual to each other.
Assuming that the population size is N, when
N<K, the population can still grow. N approximates to K, the population's growth speed decreases. N=K the population reaches equilibrium, N>K, the population must decrease in size because there are not enough resources to maintain that size.The sigmoid curve represents the logistic growth model.
In the example,
Between 0 and 5 days the population remains relatively stableBetween 5 and 10 days Chlorella approximates exponential growth.Between 10 and 20 days Chlorella experiences exponential growth. Between 20 and 25 days the population is near the K and decreases its growth rate.From 25 to 30 days, the population reached the equilibrium point, and got to stabilize.Time period during which Chlorella,
A) approximates exponential growth ⇒ Between 5 and 10 days
Between 10 and 20 days its already exponential growth.
B) has reached the carrying capacity of the culture ⇒ 25 to 30 days
Finally,
C) Growth rate per day for the 5-day period with the greatest growth rate.
First we need to figure out during which period Chlorella experiences the greatest growth rate. To do it, we just need to make the following substraction,
Growth rate per period = final concentration - initial concentration
Period 0-5 ⇒ 0.08 - 0.01 = 0.07Period 5-10 ⇒ 0.55 - 0.08 = 0.47Period 10-15 ⇒ 1.9 - 0.55 = 1.35Period 15-20 ⇒ 2.8 - 1.9 = 0.9Period 20-25 ⇒ 3.2 - 2.8 = 0.4Period 25-30 ⇒ 3.2 - 3.2 = 0Now we know that during the period from 10 to 15 days, the population experienced its greatest growth rate. But this rate is acchieved in 5 days. Now we need to find out the growth rate per day. So all we need to do, is to divide the result of the substraction per 5 days,
1.35 x 10⁶ / 5 days = 0.27 x 10⁶ cells/mL/day
The answer is 0.27 x 10⁶ cells/mL/day
