19. Engineer It In some rivers and lakes, dams
are constructed to harvest energy by converting the
kinetic energy of moving water into electrical energy.
Water from behind the dam flows through a turbine
that transforms kinetic energy into mechanical
energy. The turbine turns a generator that converts
mechanical energy into electrical energy.
The water from behind the dam could flow to the
turbine either through an opening near the middle or
top of the dam or by flowing over the top of the dam.
Which type of water flow would be the best design for
sending a consistent flow of water past the turbines?
Explain your reasoning.

Answers

Answer 1

Answer:

A hydroelectric dam converts the potential energy stored in a water reservoir behind a dam to mechanical energy—mechanical energy is also known as kinetic energy. As the water flows down through the dam its kinetic energy is used to turn a turbine.

One of the hottest ideas in engineering today is the concept of building an energy capturing system
similar to photosynthesis. The system would use light energy to make artificial food. What two
parts would such a system need, and how must these parts interact if they are to be like
photosynthesis?

Answers

The capturing device and converter are the two parts needed by the energy capturing system in order to make food.

If an energy capturing system wants to perform the same function of photosynthesis, then it must have two parts i.e. converter and capturing device. The capturing device works to capture or absorb light energy and send it to the place where this energy energy is converted into food.

The second part is the converted which convert light energy into food particles. These two parts interact with each other then the desire product will e achieved otherwise not so we can conclude that capturing device and converter are the two parts needed by the energy capturing system in order to make food.

where do photosynthetic organisms get the energy needed to make sugars during the light-independent/dark reactions?

Answers

Answer:

They use the glucose they have stored from previous photosynthesis reactions.

Explanation:

The dark reaction takes place external to the thylakoids. The energy from ATP and NADPH is used in this process to fix carbon dioxide (CO2).

What is light-independent/dark reactions?

Carbon fixation, reduction, and regeneration are the three stages that make up the Calvin cycle, which is another term for the dark reactions that take place during photosynthesis.

The stroma of the chloroplast is the location where the light-independent process, also known as dark reactions or the Calvin-Benson cycle, is carried out. Carbon-based molecules are formed through a chain of chemical events that begin with carbon dioxide. The production of ATP and NADPH during the light-dependent process supplies these processes with the energy they need to proceed.

if the carrying capacity for the north atlantic cod on the grand banks of newfoundland is 500,000 tons, when do you expect that the rate of population growth would be greatest?

Answers

If the carrying capacity for the North Atlantic cod on the newfound land is 500,000 tons, then we would expect that when there are 250,000 tons of cod on the grand banks, the population growth will be greatest.

The carrying capacity speaks volumes about the maximum amount of a species population that the ecosystem can sustain permanently provided there is the availability of water, food, habitat, and other life essentials.

In terms of population ecology, it is defined as the maximum burden that the environment can tolerate.

In population ecology, populations normally decrease above the carrying capacity while they increase below the carrying capacity. A decline in population size above the carrying capacity can be caused by a variety of factors, such as a lack of sunshine, space, or food availability.

Therefore, we can conclude that If the carrying capacity for the North Atlantic cod on the newfound land is 500,000 tons, the rate of population increase will be maximum and greatest when there are 250,000 tons of cod on the Grand Banks.

Answers

Answer:

An algal bloom.

Explanation:

The input of sewage, fertilizer runoff, and animal waste can cause the formation of an algal bloom (abundances of cyanobacteria)  because of the excess nutrients (nitrogen or phosphorus). If there are too much nutrients in the water (caused by the sewage, fertilizer runoff, and animal waste) it creates a perfect environment for excess growth, being an algal bloom. Algal blooms are toxic and are known to be harmful to the animals that rely on this source for their survival and humans as well.

In angiosperm double fertilization, one sperm nucleus fertilizes the egg to form the diploid zygote, and a second sperm nucleus fuses with the two nuclei in the central cell of the embryo sac.

The egg is the female gamete in an angiosperm. It is a haploid cell that contains one set of chromosomes. The zygote is the fertilized egg. It is a diploid cell that contains two sets of chromosomes. The zygote will eventually develop into an embryo. The central cell is a cell in the embryo sac that contains two haploid nuclei.

Double fertilization is a unique feature of angiosperms. It is a type of fertilization in which two sperm nuclei fertilize two different cells in the embryo sac. The first sperm nucleus fertilizes the egg to form the zygote. The second sperm nucleus fuses with the two nuclei in the central cell to form a triploid cell. This triploid cell will eventually develop into the endosperm, which is a food reserve for the developing embryo.

Nitrogen-fixing bacteria in the ground

Answers

Answer: 3

Explanation:

Nitrogen, the most abundant element in our atmosphere, is crucial to life. Nitrogen is found in soils and plants, in the water we drink, and in the air we breathe. It is also essential to life: a key building block of DNA, which determines our genetics, is essential to plant growth, and therefore necessary for the food we grow. But as with everything, balance is key: too little nitrogen and plants cannot thrive, leading to low crop yields; but too much nitrogen can be toxic to plants, and can also harm our environment. Plants that do not have enough nitrogen become yellowish and do not grow well and can have smaller flowers and fruits. Farmers can add nitrogen fertilizer to produce better crops, but too much can hurt plants and animals, and pollute our aquatic systems. Understanding the Nitrogen Cycle—how nitrogen moves from the atmosphere to earth, through soils and back to the atmosphere in an endless Cycle—can help us grow healthy crops and protect our environment.
