Based on the Resource Use and Conservation Virtual Lab, Which tactic can do the most to keep the water debt less than the water supply?
A. Outlawing water features in gardens
B. Replacing drip irrigation systems
C. Outlawing drip irrigation systems
D. Replacing thermal power plants.
Answers
Answer: D. Replacing thermal power plants.
Explanation:
Thermal Power Stations are some of the biggest users of water in the world because water is integral to producing electricity in them. These stations burn fossil fuels like coal which then vaporizes water so that it becomes steam which then drives turbines that produce electricity.
Water is also used for cooling high temperatures produced.
If these thermal stations are replaced with something that uses less water, it will go a long way in keeping the water debt less than the water supply.

As arizona poppy plant carries out photosynthesis, which of the following would not occur during stage 1 of the process?
Answers
Answer:
a
Explanation:
As arizona poppy plant carries out photosynthesis, Glucose is created using carbon dioxide. The Arizona poppy is a plant indigenous to the American Southwest.
What is photosynthesis ?Photosynthesis is a process that plants and other organisms used to convert light energy into chemical energy that can then be released to fuel the organism's activities via cellular respiration.
Plants absorb carbon dioxide (CO2) and water (H2O) from the air and soil during photosynthesis. Water is oxidized within the plant cell, which means it loses electrons, whereas carbon dioxide is reduced, which means it gains electrons. This converts water to oxygen and carbon dioxide to glucose.
Photosynthesis is the process by which carbon dioxide and water are converted into oxygen and glucose. The plant consumes glucose as food and produces oxygen as a byproduct. Cellular respiration is the process by which oxygen and glucose are converted into water and carbon dioxide.
Thus, As arizona poppy plant carries out photosynthesis, Glucose is created using carbon dioxide.

Explanation:
Genes are segments of DNA that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.
What are chromosomes?Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.
The term chromosome comes from the Greek words for colour (chroma) and body (soma). Scientists gave this name to chromosomes because they are cell structures, or bodies, that are strongly stained by some colourful dyes used in research. The unique structure of chromosomes keeps DNA tightly wrapped around spool-like proteins, called histones.
Without such packaging, DNA molecules would be too long to fit inside cells.

When ATP levels fall ________ binds to ________of ____________. This interaction leads to an increase of cellular ___________ , so that this is a n example of a ___________ feedback loop.
Answers
Answer:
Explanation:
The rate limiting reaction of aerobic respiration involves the phosphorylation of fructose phosphate by the enzyme phosphofructokinase. The rate at which this enzyme makes product is [increased, decreased] when ATP levels rise because the molecule ATP binds to an allosteric site on the enzyme and acts as a direct inhibitor. When ATP levels fall AMP binds to the allosteric site of phosphofructokinase. This interaction leads to an increase of cellular ATP, so that this is an example of a negative feedback loop.
An aerobic respiration can be defined as a chemical and biological process that involves the use of oxygen in living organisms to make energy (ATP) from carbohydrates (sugars) during cellular respiration.
This ultimately implies that, an aerobic respiration can take place or occur in the presence of oxygen.
What is an enzyme?An enzyme can be defined as a biological catalyst that typically speeds up (accelerates) the rate of a chemical reaction, especially by lowering the activation energy of its chemical reactants.
Factors that affects an enzymeThere are four (4) main factors that affect the actions and the rate of an enzyme and these include the following:

______ plants are important in fixing nitrogen.
a. Legume
b. Berry
c. Nut
d. Poisonous
Answers
Answer:
A
Explanation:
Legume plants are important in fixing nitrogen. Therefore, the correct option is A.
Beans, peas, lentils and clover are examples of leguminous plants that are important for nitrogen fixation. They co-exist well with rhizobia, a type of bacteria that fix nitrogen. These bacteria live in nodules on the roots of legumes and use a process called nitrogen fixation to convert atmospheric nitrogen into a form that plants can use.
Legumes can obtain substantial amounts of nitrogen, an important nutrient for plant growth, without being entirely dependent on soil nitrogen, because of their ability to fix nitrogen. Legumes play an important role in agriculture and ecosystems, by adding nitrogen to the soil and increasing its fertility. Legumes are valuable crops because of their high protein content as well as their ability to improve soil health by fixing nitrogen.
Therefore, the correct option is A.

Bison in Yellowstone National Park have a food-limited carrying capacity that determines how their population grows. If the population grows too large, some bison will either starve or migrate to search for more food. The park is able to support a maximum population of 4,500 bison. Park conservation officials must watch the population and prevent the bison from overpopulating, since they would migrate to nearby farms, causing agricultural damage and creating hazards to drivers. The bison begin to migrate when the population reaches 4,000 because of competition for food. If the current population size of bison is 3,652 and the maximum growth rate of the population is 0.28, calculate the population size after one year and determine whether the park will need to take measures to control the population.
A. The population will be 3,845 after a year. The bison will not pose a problem until the following year, and no conservation action will need to take place.
B. The population will be 4,675 after a year. Some bison will need to be removed to prevent migration, since they will surpass the resource availability.
C. The population will be 1,023 after a year, since the growth rate is too low. Conservation efforts will need to focus on increasing the bison population.
D. The population will be 4,500 after a year. The bison cannot exceed the carrying capacity, so they will stop reproducing. Some bison will need to be removed.
Answers
Answer:
A. The population will be 3,845 after a year. The bison will not pose a problem until the following year, and no conservation action will need to take place.
Explanation:
The exposed example refers to a population that exhibits a logistic growth model, Where the principal limiting factor is food availability
N is the total size of the populationNt the population size after a T timeK the carrying capacityr the population growth rate per capitaWhen N < K the population has not reached the maximum size that can be supported by the environment. It can increase in size.
When N = K the population has reached the maximum size that can be supported by the environment. It can not grow anymore. The population reached a maximum point delimited by available resources, such as food
When N > K the population has supered the maximum size that can be supported by the environment. It must decrease in size. because there are not enough resources.
To calculate the population size after one year, we need to use the following equation.
N t+1= Nt+rN(1-N/K)
Available data:
K = 4500
N = 3652
r = 0.28
Nm= 4000
N/K = 3652/4500 = 0.8115
r.N = 0.28 x 3652 = 1022.56
N t+1= Nt+rN(1-N/K)
N t+1= 3652+1022.56(1-0.8115)
N t+1= 3652+1022.56(0.1885)
N t+1= 3652+192.753
N t+1= 3844.75
rounding up to 3845
