The endometrium is the inner lining of the uterus. During the ovulation period, this wall thickens as it prepares the uterus for the eventual fertilization of an egg cell. It is composed of a basal layer and a functional layer, in which the latter sloughs off/sheds off during menstruation.
Therefore, it is the ENDOMETRIUM layer <span>of the uterus undergoes dramatic changes in thickness and structure during the uterine cycle responding to hormones.</span>
The correct answer is A. His diet should include foods such as eggs, nuts, and fish.
Explanation:
The excerpt from the journal explains the importance of protein intake for athletes as this contributes to many body functions such as "enzyme production" or "growth and repair of tissues". In this context, athletes will need to have an appropriate protein intake, which is essential to growth muscles or repair them if there is a lesion. Moreover, this can be obtained through the intake of foods such as eggs, nuts, fish, grains, among others. In this context, the best decision is expressed in option A.
Answer: Cystic Fibrosis
Explanation:
Cystic fibrosis (abbreviated CF) is an autosomal recessive genetic disease that mainly affects the lungs, and to a lesser extent the pancreas, liver and intestine, causing an abnormally thick, sticky mucus to build up in these areas. This mucus collects in the airways of the lungs and pancreas. The main cause of morbidity and mortality is pulmonary involvement, which accounts for 95% of deaths, mainly due to repeated infections caused by bronchial obstruction due to the secretion of very thick mucus.
This build up of mucus causes life-threatening lung infections and serious digestive problems. It is one of the most common types of chronic lung disease in children and young adults, and is a life-threatening disorder; patients often die from lung infections due to <em>Pseudomonas</em> or <em>Staphylococcus</em>.
<u>It is a hereditary disease produced by a mutation in the gene encoding the cystic fibrosis transmembrane conductance regulator (CFTR) protein. This protein is involved in the passage of chlorine ion through cell membranes and its deficiency alters the production of sweat, gastric juices and mucus. </u>The disease develops when neither allele is functional. Over 1500 mutations have been described for this disease, most of which are small deletions or point mutations; less than 1% are due to mutations in the promoter or chromosomal rearrangements. However, many people carry the CF gene, but do not have any symptoms. This is because a person with this disease must inherit 2 defective genes, 1 from each parent.
<u>There is no curative treatment, however there are treatments that allow the improvement of symptoms and extend life expectancy. In severe cases, the worsening of the disease may necessitate a lung transplant.</u>
There are concerns over the inadvertent effects, such as the creation of food that can cause an allergic reaction, GMO that can cause harmful genetic effects, and genes moving from one species to another that is not genetically engineered.
