The initial increase in heart and breathing rates during the skin diving trip was probably a result of: a. activation of the sympathetic autonomic nervous system by the new experience. b. activation of the parasympathetic autonomic nervous system by the new experience. c. hypoxia caused by the inability of her blood hemoglobin concentration to supply sufficient oxygen for the strenuous exercise of swimming at sea level. d. elevated core body temperature caused by swimming in warm tropical waters.

Answers

Answer 1

Answer:

Answer:

a. activation of the sympathetic autonomic nervous system by the new experience.

Explanation:

The sympathetic division of the autonomic nervous system generates a flight or fight response. This is a series of physiological processes that start when a person has any stress, new experience or emergency conditions such as the first diving trip. One such response produced by activated sympathetic division is increased heart rate to pump more blood and deliver more oxygen to body cells and tissues. Also, the person experiences an increased breathing rate to compensate for the increased oxygen demand.

Biological classification how are organisms grouped sorted and classified

Answers

Biological classification is the process by which organisms are grouped, sorted, and classified based on their similarities and differences. Organisms are grouped into categories called taxa, which follow a hierarchical system. The major steps involved in biological classification are:

1. Observe and compare organisms: Scientists study various organisms and their characteristics, including physical appearance, behavior, and molecular makeup.

2. Identify shared characteristics: By comparing organisms, scientists identify common traits and features that can be used to group them together.

3. Create taxonomic groups: Based on these shared characteristics, organisms are grouped into hierarchical categories, such as kingdom, phylum, class, order, family, genus, and species.

4. Assign scientific names: Each group and individual organism is given a unique scientific name, usually following the binomial nomenclature system, where the genus and species are used to identify an organism.

5. Continuously revise and update classifications: As new information and discoveries are made, scientists may need to reevaluate and revise the classification system to ensure accuracy and reflect the relationships among organisms.

Overall, biological classification helps scientists to better understand and organize the vast diversity of life on Earth, making it easier to study and conserve species and ecosystems.

What organelles could you find in lettuce cells but not mouse cells?

Answers

Chloroplasts are found in lettuce cells but not mouse cells.

What is the function of chloroplasts?

A chloroplast is a type of membrane-bound organelle known as a plastid that conducts photosynthesis mostly in plant and algal cells.

Chlorophyll, the primary pigment used in photosynthesis, reflects green light and absorbs red and blue light most strongly.

Chloroplasts are plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process. By doing so, they sustain life on Earth. Chloroplasts also provide diverse metabolic activities for plant cells.
