The flap of elastic cartilage that keeps food and liquids from entering the larynx during swallowing is called the epiglottis.

It is a flexible, spoon-shaped structure located at the base of the tongue and above the larynx. During swallowing, the tongue pushes food and liquid towards the back of the mouth, triggering the epiglottis to fold backwards and cover the opening of the larynx.

This prevents food and liquid from entering the airway and instead directs them towards the esophagus for digestion. The epiglottis also helps protect the airway by trapping foreign particles and preventing them from entering the lungs.

Characteristic of striated muscle in all types of cells is called Myofibril. A sarcomere-based component found inside striated muscle fibers.

Its filament pattern, which is parallel to the long axis of the muscle fiber, creates the striations that are unique to striated muscle cells. The sarcomere is made up of bundles of thin filaments of actin that are interdigitated and bordered by bundles of thick filaments that contain myosin. The alternating of areas with thick filaments (A-Band) and thin filaments (I-band) gives muscle its striated appearance.

Actin and myosin repeating bands, which are present along the length of myofibrils, give skeletal muscle tissue its striated appearance. As myofibrils are aligned in the cells, the appearance of the entire cell is striated. Dark A bands and light I bands repeat along myofibrils.

Water molecules move into and out of the cell through a process called osmosis.

Osmosis is the process of movement of water molecules through a semi-permeable membrane from an area of high water concentration to an area of low water concentration. The semi-permeable membrane allows only water molecules to pass through. The osmosis process is controlled by the osmotic pressure, which is the pressure caused by the difference in water concentrations on either side of the membrane. When the osmotic pressure is equal on both sides, the movement of water molecules stops. Osmosis is essential for maintaining cell homeostasis and is used in many biological processes such as transporting nutrients, removing toxins, and balancing pH levels.

At midnight, the leaf of a plant undergoes several changes, including physiological and metabolic activities. Plants undergo changes in metabolic activities even when they are not in the process of photosynthesis.

During the day, the leaf of a plant carries out photosynthesis and other metabolic activities. However, at midnight, plants cease all activities, including photosynthesis. The leaf of a plant has stomata that allow gases to enter and exit the leaf. These gases are vital in the process of photosynthesis, where carbon dioxide enters and oxygen leaves the leaf. At night, the stomata close, and no more gases are exchanged. The stored carbon dioxide is converted into glucose and other sugars. This process is called respiration. Respiration is essential for the survival of plants because it produces ATP, the energy currency of the plant. Plants also undergo a process called transpiration, where water is taken up through the roots and exits through the stomata. At night, the stomata are closed, and the plant conserves water. However, there is still some transpiration going on in the leaf, but at a much slower rate. In conclusion, at midnight, the leaf of a plant is not carrying out photosynthesis, but it is still undergoing metabolic activities, such as respiration and transpiration.

When two DNA fragments with complementary sticky ends join, the activity of dna ligase ensures that the join is permanent is catalyze the formation of a phosphodiester bond they form a stable bond.

DNA ligase has a unique property that enables it to catalyze the formation of a phosphodiester bond between the 3'OH of one nucleotide and the 5' phosphate of the other, resulting in the formation of a new phosphodiester bond and the loss of a water molecule (dehydration reaction). When two DNA fragments with complementary sticky ends join, the sticky ends anneal to each other, and the base pairs form hydrogen bonds. This creates a short-lived intermediate that can be further stabilized by the action of DNA ligase. The DNA ligase enzyme then binds to the junction of the two strands and catalyzes the formation of a phosphodiester bond, joining the two DNA fragments permanently.

This occurs through a complex series of reactions that involve a high degree of specificity and accuracy. The binding of the DNA ligase enzyme to the DNA ends is driven by specific recognition sequences that are present on the DNA fragments. These recognition sequences allow the enzyme to bind to the DNA and guide it towards the correct site of ligation. Overall, DNA ligase ensures that the join is permanent by catalyzing the formation of a covalent bond between the two DNA fragments. This reaction is specific and accurate, ensuring that the two fragments are joined together in the correct orientation and position.
