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.
You WILL lose thermal energy cuz heat will always flow from warmer to cooler.
Hope it helps!
Answer:
The organelle that conduct respiration for the cell is MITOCHONDRIA.
Explanation:
The cells of living organisms are made up of different organelles, each of the organelles have specific functions, which they perform. The mitochondria is the cell organelle that is responsible for carrying out respiration in the cells. Respiration involves the breaking down of glucose molecules in order to produce energy in form of ATP. Mitochondria is also called the power house of the cell because of its function of energy production.
Explanation:
Water molecules from the less conentrated right side, will flow into the left side til they equilibrate- at equilibrium both sides will have the same concentration of solute.
In diffusion small water molecules can move across the phospholipid bilayer acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds. Similarly, during osmosis the water passes through the membrane due to the difference in osmotic pressure on either side of the phospholipid bilayer, this means that the water moves from regions of high osmotic pressure/concentration to regions of low osmotic pressure /concentration.
