Comparing the four most common types of power plants in Alberta (coal, natural
gas, wind, and hydroelectric), which has the lowest efficiency in electricity
generation? and why?
Answer:
Coal.
Explanation:
Steam power plant has the lowest efficiency in electricity production which can only be run with the use of fossil fuels such as coal. The efficiency of this power plant is the lowest because large amount of coal is converted into smoke and other gases and very less amount of coal into heat energy. This coal is used to produce heat energy which can be used in the heating of water to produce steam. This steam is used to move turbines which turn mechanical energy into electric energy.

Scott made a model of the water cycle by filling a tub with water, covering the tub with clear plastic, and placing a heat lamp over the tub. After a few days, he observed water droplets collecting on the plastic wrap. What process formed the water droplets in Scott's model?
Answer:
The correct answer is - condensation.
Explanation:
When humid air comes in contact with the cold surface and we get the water in form of droplets, it is called condensation. In other words, condensation is the change of water vapor to the water exactly opposite of the evaporation process.
In the given experiment of Scott where droplets are collected on the plastic surface which simply illustrates the phenomenon of condensation as the water evaporated due to the heat of the lamp and condensed on the surface of plastic wrap.
Answer:
C
Explanation:
condensation

Yeast undergo anaerobic respiration (fermentation), where glucose is broken down into two (2) ATP and two (2) pyruvate. This pyruvate is then used to form what waste product?
The pyruvate is then used to form Ethanol [tex][C_2H_5OH][/tex] and Carbon dioxide [tex][CO2_][/tex].
What is Anaerobic respiration?Anaerobic respiration is defined as respiration using an electron acceptor other than molecular oxygen where oxygen is not the final electron acceptor, the process still uses the respiratory electron transport chain.
Anaerobic respiration is described as the process in which there is incomplete oxidation of glucose in the absence of oxygen which is commonly known as fermentation.
One type of fermentation is alcohol fermentation where the pyruvate is decarboxylated [tex](CO_2 leaves)[/tex] to form acetaldehyde. Hydrogen atoms from NADH+. H+ are then used to help convert acetaldehyde to ethanol. NAD+ results.
Thus, the pyruvate is then used to form Ethanol [tex][C_2H_5OH][/tex] and Carbon dioxide [tex][CO2_][/tex].

Human body cells are constantly moving water into and out of themselves. Under what conditions can a human body cell achieve homeostasis?
Homeostasis is the process by which the body maintains a stable internal environment despite changes in external conditions. The body has several mechanisms to help maintain overall fluid balance, such as the renin-angiotensin-aldosterone system and the anti-diuretic hormone (ADH) system.
What is homeostasis?Human body cells are constantly moving water into and out of themselves, and they rely on a complex system of transport proteins and channels to regulate the movement of water and other molecules. Under normal conditions, human body cells can achieve homeostasis by maintaining a balance between the concentration of solutes inside and outside the cell. This balance is maintained through a process known as osmoregulation, which involves the movement of water and solutes across the cell membrane.
Hence, homeostasis is the process by which the body maintains a stable internal environment despite changes in external conditions. The body has several mechanisms to help maintain overall fluid balance, such as the renin-angiotensin-aldosterone system and the anti-diuretic hormone (ADH) system.

In an example food chain, rabbits only eat plants.
Which type of consumer are the rabbits?
plants and algae. These organisms are called primary consumers or herbivores. Some examples are rabbits, deer, tadpoles, and caterpillars. organisms are called secondary consumers.
Answer:
Herbivores
Explanation:
A rabbit is very close to the bottom and they are ‘consumers’. They are herbivores, meaning that they mainly eat plant matter. They are also prey animals so larger animals capture and eat them.

Case Ico-delete Highlights
A 42-year-old woman presents for an evaluation of back pain. She states that she has a history of recurrent UTIs; she notes that on occasion her urine appears red. Upon physical examination, she demonstrates CVA tenderness. Her vital signs include blood pressure of 145/90 mm Hg, respiratory rate of 16 breaths/min, and heart rate of 72 bpm. Urinalysis shows leukocyte esterase 1+, protein trace, and blood 3+. The microscopic examination reveals 5-10 WBCs/hpf and 20-30 RBCs/hpf. An abdominal ultrasound demonstrates multiple, bilateral fluid collections within the kidneys.
Question
What, if any, is the most likely underlying renal pathology?
Answer:
The correct answer would be - polycystic kidney disease.
Explanation:
The given clinical picture or information suggests that it is most probably an infection that takes place in one or both the kidneys and leads to the setting of polycystic kidney disease.
The given symptoms such as abdominal or flank pain, recurrent UTIs, blood in the urine, and hypertension are characteristic symptoms of polycystic kidney disease. Cystic lesions found on abdominal ultrasound are a confirmation of the disorder.
The key disease of this polycystic disorder is Goodpasture syndrome which shows symptoms of both glomerulonephritis and pulmonary hemorrhages, and medullary sponge kidney disorder.

During the light reactions of photosynthesis, plants convert light energy into energy the plant can use. Where is the energy stored
Answer:
Photosynthesis is a process where plants and other organisms convert energy from the sun into a chemical energy that through cellular respiration can be later released in order to fuel the organism's metabolic activities.
The energy which is stored in the form of sugar is broken down into starch entering the mitochondria to produce energy. The energy is stored in the chemical bonds. To obtain the energy, organisms take energy-rich compounds such as glucose and breaks them down to release their energy. The organism traps the released energy and stores it in a form of adenosine triphosphate or ATP.
