20. A research company wants to design a new type of artificial heart valve that will be less likely to be rejected by a person's immune system. Which step in the design process should the company perform before building a prototype of the heart valve?
A. Find test subjects for the new heart valve.
B. Conduct research on existing artificial heart valves.
C. Determine how to manufacture the new heart valve.
D. Evaluate the performance of the artificial heart valve.
Answer:
C. Determine how to manufacture the new heart valve.
I think it seems a little obvious (I'm probably wrong)because obviously before doing something important your going to think about how to do it first.
The step in the design process that should the company perform before building a prototype of the heart valve is to determine how to manufacture the new heart valve. Thus, the correct option for this question is C.
What is meant by a Prototype?A prototype may be defined as a sample, model, or liberation of a product that is significantly built in order to test a concept or process. This term is used in a variety of contexts, including semantics, design, electronics, and software programming.
A prototype is typically utilized in order to determine a new design to increase precision by system analysts and users. If an organization or individual wants to design any type of structural and functional unit, they must require to know its actual mechanism of it.
Then they are allowed to manufacture the concept with regard to their discovery. So, a research company requires to demonstrate how to manufacture the new heart valve with the help of a prototype.
Therefore, the correct option for this question is C.

Mt. Pinatubo, a volcano in the Philippines, erupted in 1991. The eruption resulted in the cooling of Earth's surface
for two years.
What can you deduce from the information given?
O Solar energy seeped through the atmosphere,
O The eruption caused sunspot activity to increase.
O The volcano released a lot of sulfur dioxide and ash,
O Greenhouse gases caused the cooling of Earth's surface.
Answer: this is easy, i think
Explanation:
The volcano released a lot of sulfur dioxide and ash
According to question, "C" which is the volcano released a lot of sulfur dioxide and ash.
What is a volcano and what causes its eruption?When magma builds up in the magma chamber, it forces its way up to the surface and erupts, often causing volcanic eruptions.
In the ocean, volcanoes erupt along cracks that are opened in the ocean floor by the spreading of two plates called a mid-ocean ridge.
Thus, the volcano released a lot of sulfur dioxide and ash is correct.

I need help with my science question Which molecules do cells need to release energy? Here is the choices.Claim 1: Cells need glucose to release energy. Claim 2: Cells need amino acids to release energy. Claim 3: Cells need oxygen to release energy. Claim 4: Cells need glucose AND amino acids to release energy. Claim 5: Cells need glucose AND oxygen to release energy Claim 6: ALL?
Answer:
Claim 5: Cells need glucose AND oxygen to release energy.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage through the breathing of oxygen used to obtain energy from the food ingested.
Hence, cells need glucose and oxygen to release energy.
The statement 'cells need glucose AND oxygen to release energy' is correct (Claim 5).
Cellular respiration is a series of metabolic reactions by which aerobic cells used oxygen and the energy stored in the chemical bonds of foods (e.g., glucose) to produce ATP.
Cellular respiration has three main stages: glycolysis, the citric acid cycle and oxidative phosphorylation.
During glycolysis, a molecule of glucose is used to create two molecules of pyruvate, which enter into the citric acid cycle.
Oxygen is the last acceptor of electrons in the electron transport chain of oxidative phosphorylation.
In conclusion, cells need glucose AND oxygen to release energy.

As the root tip begins to grow downward, the stem will begin to grow and push upward. How does the bluebonnet root knwo which way is down? How does the stem know whch way to stretch to reach sunlight? The answer is geotropism. This property of plants allows them to orient their growth with the direction of gravity. What phrase helps you determine what orient means? a. Property of plants b. To reach the sunlight c. How does the stem know d. With the direction of gravity
Answer:
d. With the direction of gravity
Explanation:
Geotropism or gravitropism is a coordinated process of plant growth in fungi and plants to respond to the changing gravity. It a general feature that are found in higher and lower altitude plants.
