Answer:
The trachea, commonly known as the windpipe, is a most important organ as it allows the passage of air into the lungs. Because the trachea has a soft tissue tubular formation, it needs a base of stronger, yet flexible stuff that will give it support, protect it, and still allow the passage of air into the lungs.
This is precisely the task of the tracheal rings, or cartilage rings in the trachea. These rings are made out of cartilaginous tissue, which is much stronger than the soft tissue of the tubule, but are still flexible enough to not close down the tube when air is flowing in. Thus, the tracheal rings have two tasks: one, provide support and protection for the much softer and more vunerable tube of soft tissue through which the air passes, and two, provide flexibility so that air can flow easily.
If these tracheal rings did not exist, if they are crushed, or removed, a person´s trachea would simply collapse and the person would die as air would not be able to flow through to the lungs.
According to Mendel's Law of Inheritance, one copy of a gene is passed randomly from each parent to their offspring. This is why gametes have half the usual number of chromosomes
The law of assortment states that different genes are not connected. In other words, the gene for eye color is not influenced by, nor does it influence, the gene for hair color. This allows gametes to form with a random mixture of traits.
The cell division that creates gametes according to these principles is known as meiosis.
Explanation:
Gregor plant scientist, through his work on pea plants, discovered the elemental laws of inheritance.
He deduced that genes are available in pairs and area unit heritable as distinct units, one from every parent. Plant scientist half-tracked the segregation of parental genes and their look within the offspring as dominant or recessive traits.
The Principle of freelance Assortment describes however completely different genes severally cut loose each other once generative cells develop. The freelance assortment of genes and their corresponding traits was initially ascertained.

i'm not sure if they are all correct so sorry ✧
Answer:
Within a protein, multiple amino acids are linked together by peptide bonds, thereby forming a long chain.
Phosphorus. It's not abundant, but it's important. There are traces of it in our bones and in the "phospho-lipid bilayer" of the membrane.
Hope that helps!
