Rickets is the disease in children in which an inefficient mineralization of the bone forming tissue causes deformities. This condition results in weak or soft bones in children, normally due to an extreme and prolonged deficiency of vitamin D. Vitamin D promotes the absorption of calcium and phosphorus from the gastrointestinal tract. The symptoms include bowed legs, stunted growth, bone pain, large forehead, and trouble sleeping among others.
When a gene is turned off, It no longer provides the directions for making proteins. this means that the proteins needed to fulfill a particular job ( let’s say, tolerate lactose ) aren’t produced.
It's reported as statistic
A trait is a characteristic, such as color or size, that is inherited by an offspring from its parents. The genes that control a trait come in pairs, one gene from each parent. We represent these gene pairs by writing a combination of two letters. For example, if one parent contributes a gene for blue eyes (c), and other parent contributes a gene for brown eyes(C), then we write the offspring’s eye color trait as Cc. This combination, of the two genes that determine the trait, is called a genotype. Hope this helped :)
The correct answer is xylem.
<span>Xylem is a type of plants’ transport tissue. The function of the xylem is to transport water and solutes from the roots to the leaves. The xylem transport system is composed of continuous tubes called xylem vessels. Xylem vessels enable transport (after absorption from the soil through root hair cells) up the stem to the leaves. Water evaporation from the leaves (transpiration) is also mainteined by xylem. Xylem vessels consist of dead cells with a thick, strengthened cell wall with a cellulose and hollow lumen. Vessel element is one of the cell types found in xylem and together with tracheids, is involved in the actual transport.</span>
