Answer:
In cells. The increase in size and changes in shape of a developing organism depend on the increase in the number and size of cells that make up the individual. Increase in cell number occurs by a precise cellular reproductive mechanism called mitosis.
Answer:
Growth hormone deficiency can result in dwarfism.
Children with this deficiency have abnormally short statue.
Explanation:
Growth hormone deficiency can result in dwarfism when inadequate amounts of growth hormone are produced in the body. Children that have this hormone defieciency possess an abnormal short stature and normal body proportions. This condition occurs when the pituitary gland do not produce enough growth hormone.
Growth hormone therapy in little children have been a subject of great ethical debate. The benefits of this therapy in children may not necessarily provide the means to overcome the short physical or psychological impact. The studies show individual variability in growth response. Growth hormone injections that is needed for treatment require careful consideration by the patient and parents.
The appropriate response is letter B. Genetic engineering is the way toward breaking the normal limits that exist between species to create new life frames that will deliver an assortment of wanted characteristics. Hybridization is the preparation of the blossom of one animal types by the dust of another species or manufactured cross-fertilization.
Answer:
The function of the physis or growth plate is to allow the growth in length of the bones (both long as short) through the endochondral ossification process.
Explanation:
The epiphyseal plates are areas of active growth of new bone at the ends of the bones, made up of cartilage that hardens once the child is fully developed. Epiphyseal plates help determine the length and shape of the adult bone eventually. It is the last part of the bones to harden, and therefore they are vulnerable to fractures. The complication of the involvement of the growth plate is the deformity or lack of growth of the bone, leaving the limb twisted or shorter than the contralateral one.Growth disturbances are more frequent when the affected area is very large or when it involves the area of the knee joint. In cases of shoulder or wrist involvement, deformities rarely occur. The alterations are more common when the lesions occur in younger children, because they have a longer growth period.
Answer:
By extensively filtering the water in a lake or a bay they can clear it enough to increase light penetration thus affecting benthic macroalgal communities by facilitating growth. There are numerous examples of animals and plants that function as ecosystem engineers.
