C why might it be important to move from non renewable resources to renewable resources
Organic means it is made only of carbon.
Explanation:
The all four types of macromolecule are organic means these all four type of macromolecule made up of carbon. These four macro molecules are carbohydrate, protein, nucleic acid and Proteins. All are essential cell component perform a wide array of function.
Biological macromolecule is organic so they contain carbon. A part of carbon they contain nitrogen, hydrogen and additional minor element. Enzymes and some hormone are example of protein.
Well our bodies are made from atoms which are also in supernovas. theoretically atoms make everything so that could be a connection. also, supernovas and bodies all have a time clock, or they were born at one point and will end up dying at one point.
Answer:
The correct answers are:
1. closing
2. the ventricles and arteries,
3. a constricted trachea
Lub is the first sound of a heartbeat and is mentioned as S1. It is usually produced due to the closing of tricuspid and and mitral or bicuspid valves present between atria and ventricles.
Tricupsid is located between atrium and ventricle of the right hand side and mitral valve is located between atrium and ventricle of the left hand side. They prevent the back flow of blood from ventricles to their respective atria.
Dub, being the second sound is written as S2. It is produced due to the closing of pulmonary (located between right ventricle and pulmonary artery) and aortic valves (located between left artery and aorta).
These valves prevent the back flow of blood from arteries into the ventricles.
The time between the two sounds is often taken as the measure of the diastole i.e. ventricular filling.
Wheezing refers to a high-pitched sound produced when a person breathes, especially during exhale. It is caused by constriction of the airways or inflammation. It is considered as a symptom of various diseases such as asthma, COPD, allergies, bronchitis etc.
Answer:
Breed "pure" mice with known genotypes that exhibit specific fur and eye colors, and learn how traits are passed on via dominant and recessive genes. Mice can be stored in cages for future breeding, and the statistics of fur and eye color are reported every time a pair of mice breed.
