Answer:
C, a long absolute refractory period.
Explanation:
Tetanus is not possible in cardiac muscle tissue because cardiac cells have longer action potentials and a very long refractory period compared to other cells. This helps prevent the heart from cramping and seizing up.
Answer:
pulmonary circulation
Explanation:
The pulmonary circulation moves the blood between the lungs and heart. Since the blood carries oxygen the heart pumps it to every body part including the lungs so we can maintain homeostasis.
Answer:
Figure 3
Explanation:
A mixture is a substance made up of two or more different kind of atoms arranged in such a way that they are not chemically linked or joined. This accounts for the reason a mixture can be separated easily. In the figures attached as an image in this question:
- Figure 1 represents an element because it is made up of only hydrogen atoms chemically bonded together to form a molecule.
- Figure 2 represents a compound because it contains hydrogen and carbon atoms chemically joined together.
- Figure 3 represents a MIXTURE because it contains the oxygen and carbon atoms, which are not chemically joined to one another. As seen in the image, the oxygen atoms are not joined to the carbon atoms.
- Figure 4 represents a compound because it contains oxygen and hydrogen atoms chemically bonded together.
Answer:
1.Carbon dioxide is converted to sugar used for food. - 1. Location- A
2.Carbon trapped in fossil fuels is converted to carbon dioxide. - 2. Location- C
3.Organic carbon is converted to fossil fuels. -3. Location- E
4.Carbon dioxide is converted to carbonates.- 4. Location- D
5.Sugar is broken down and converted to carbon dioxide. - 5. Location- F
Explanation
1. Carbon dioxide is converted to sugar used for food: The carbon dioxide is converted into sugars by the process of photosynthesis, which occurs in the green plants. Plants trap carbon dioxide and sunlight from the atmosphere, to synthesize their food.
2. Carbon trapped in fossil fuels is converted to carbon dioxide: The fossil fuel produced deep inside the earth, acquired by the factory. From the factory the carbon dioxide liberated to the atmosphere.
3. Organic carbon is converted to fossil fuels: The organic carbon obtained after the degradation of organic matter is responsible for the synthesis of fossil fuels.
4. Carbon dioxide is converted to carbonates: The carbon dioxide from the atmosphere gets dissolved with water of the water body and termed as carbonic water.
5.Sugar is broken down and converted to carbon dioxide: The glucose or sugar as a source of food in plants gets broken down into carbon dioxide and water by the process of respiration.
Answer: warm front
Explanation: When a warm air mass meets a cold air mass, the warm air rises since it is lighter. At high altitude it cools, and the water vapor it contains condenses. This type of front is called a warm front. It generates nimbostratus clouds, which can result in moderate rain.
