In this activity, you will identify the conclusions that can be drawn from Pasteur's experiments using S-shaped neck flasks. Which of the following conclusions can be drawn from Pasteur's experiment involving the flasks with S-shaped necks? Select all statements that apply. a. Pasteur's observations support the theory of spontaneous generation. b. Microbes can be blocked from accessing favorable growth environments. c. Beef broth is an unsuitable environment for growing microorganisms. d. Microbial life can be destroyed by heat. e. Microorganisms can be present in nonliving matter, such as air, liquids, and solids. f. Microbial life can arise from nonliving matter. g. Pasteur's observations support the theory of biogenesis.

Answers

Answer 1
Answer:

Answer:

The correct answer would be :

b. Microbes can be blocked from accessing favorable growth environments.

d. Microbial life can be destroyed by heat.

e. Microorganisms can be present in nonliving matter, such as air, liquids, and solids.

g. Pasteur's observations support the theory of biogenesis.

Explanation:

Pasteur's experiment with s-shaped neck flasks indicated that organisms can't emerge from nonliving materials under the conditions that existed on Earth during his lifetime.

It helps in testing the role of airborne contaminants in producing microbes in the nonliving matter by the biogenesis theory. His experiment showed and supports that heat can kill or destroy microbial life.

Thus, the correct answer would be -  b., d, e., and g.
Answer 2
Answer:

Final answer:

Pasteur's experiments using S-shaped neck flasks led to several conclusions: microorganisms can be blocked from accessing favorable growth environments, microbial life can be destroyed by heat, microorganisms can be present in nonliving matter, and Pasteur's observations support the theory of biogenesis.

Explanation:

Pasteur's experiments using S-shaped neck flasks led to several conclusions:

  1. Microbes can be blocked from accessing favorable growth environments. The S-shaped necks prevented airborne microbes from entering the flasks, demonstrating that microorganisms require a suitable environment to grow.
  2. Microbial life can be destroyed by heat. Pasteur heated the broth in the flasks, killing any existing microorganisms present. This suggested that heat can kill microbes.
  3. Microorganisms can be present in nonliving matter, such as air, liquids, and solids. Although Pasteur's experiments did not address the origin of microbial life, they supported the idea that microorganisms can exist in nonliving materials.
  4. Pasteur's observations support the theory of biogenesis. The results of his experiments contradicted the theory of spontaneous generation and instead supported the concept of biogenesis, which states that living organisms arise from other living organisms.

Which bones are most important for protecting vital organs?

Answers

Answer:

The correct answer would be ribs (rib cage), skull and spine.

Explanation:

Our skeletal system provides support to the body, shapes and protects vital organs. There are three major and most important bones that protect our vital organs. These three bones are - ribs or rib cage, skull, and spine.

The rib cage or ribs protect the most important organs of the body - heart, and lungs. Ribs are attached to the vertebral column and sternum in the thorax.

Skull is also protecting one of the most important organs which are the brain. The brain is a very vital and sensitive organ. Skull is consists of twenty-two bones.

Spine has 33 vertebrae bones that interlock to form the spinal column. It protects the spinal cord, nerve roots, and other organs.

Thus, the correct answer would be ribs, skull, and spine.
The ribcage protects the heart and the lungs and the cranium (skull) protect the brain

Rigor mortis typically disappears after how many hours?

Answers

The answer is 8-12 hours.

Rigor mortis is caused by chemical reactions in muscles after death. Usually, parts of the body become stiffened because ATP is lost after death. After death oxygen concentration in the body decreases because ATP is still being produced and respiration is stopped. When there is no oxygen, anaerobic glycolysis produces ATP using glycogen. When glycogen is depleted, ATP production stops, and rigor mortis begins 2 hours after death. ATP is required during muscle respiration, but now there is a limited concentration of ATP, and its production is stopped. So, muscles could not be relaxed. 8-12 hours after death, muscle fibers are decomposed by enzymes or bacteria, and body relaxes, exiting rigor mortis.

Answer: The answer is not 8-12 hours

Explanation:

That 8-12 hours is for Liver Mortis.

What is the greenhouse effect?

Answers

The greenhouse effect is the trapping of the sun's warmth in a planet's lower atmosphere due to the greater transparency of the atmosphere to visible radiation from the sun

A greenhouse is made of glass. It traps the Sun's energy inside and keeps the plants warm, even in winter.

A greenhouse is a house made of glass. It has glass walls and a glass roof. People grow tomatoes and flowers and other plants in them. A greenhouse stays warm inside, even during winter. Sunlight shines in and warms the plants and air inside. But the heat is trapped by the glass and can't escape. So during the daylight hours, it gets warmer and warmer inside a greenhouse, and stays pretty warm at night too.
