Hi lovely,
Gregor Mendel discovered the fundamental laws of inheritance and that determined that genes come in pairs.
A cell membrane protects a cell from it's surroundings. The cell membrane controls the movement of substances from the outside and inside of cells and organelles.
Breathing is the function of our body to let air flow to the lungs. It is important because it serves the purpose of bringing the amount of oxygen the body needs to work properly, and flushing out the toxic substances our body produces.
The diaphragm also plays its important role in respiratory system because it creates more space in our chest cavity, allowing the lungs to expand when we inhale.
The larynx connects the naso- and oro- pharynx with the trachea, functioning in air conduction, vocalisation and in obstructing passage of ingesta into the trachea during deglutition. The trachea divides into left and right mainstream bronchi. Bronchi give away to smaller conducting airways, bronchioles.
The walls of the alveoli share a membrane with the capillaries, this relatively lets the oxygen and carbon dioxide diffuse between the respiratory system and bloodstream. They bring oxygen into our body through inhalation and send carbon dioxide out called exhalation and overall process is respiration
Pneumonia is a life threatening illness because if our lungs is filled with fluid then they won’t be able to function normally and won’t be able to transfer enough oxygen to your blood or get rid of the carbon dioxide in our bloodstream
Club mosses, horestails and ferns are types of vascular seedless plants.
These types of plants reproduce through spores rather than the fertilization of seeds. The weight of spores is much lighter than that of seeds. These plants also require ample water for fertilization. The combination of light wind and moisture that is needed for reproduction means that you will often find these plants in damp or wet areas. Thinking of how mosses and horsetails are found in wetter areas will help you to remember this.
