Answer:
The correct answer is option - chondrosis: freely moving joint.
Explanation:
Chondroitin is the condition, not a joint which is basically is the loss or softness of the smooth cartilage that covers the joint of the knee at the back of the kneecap. This condition occurs due to prior injury, overweight or obesity, and a more common cause is an acceleration of the cartilage abnormally at the kneecap.
It is also known as cartilage deterioration which is joint effusion. All three joints are correctly matched. amphiarthrosis is a slightly movable joint, synarthrosis is an immovable joint, and gomphosis is a joint that articulation between tooth and bone.
Thus, the correct answer is option - chondrosis: freely moving joint.
The first one, <span>By having white blood cells to attack pathogens. this is because blood also has white blood cells. and the immune system has pathogens. so the blood cells help attack pathogens.</span>
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>
Answer: (B) a phenomenon most scientists agree that is caused by fossil fuels burned by human beings.
Explanation:
Global warming is a phenomena of the environment. In this the earth atmosphere is affected by the harmful greenhouse gases. The majority of the greenhouse gases are produced by the virtue of burning of the fossil fuels. The burning of the fossil fuel liberates gases which are toxic. These gases have a diatomic structure, which enable them to absorb the heat energy from the sunlight. Thus these gases make the atmosphere hot. As a result of this the atmosphere of earth is becoming warm globally and glacier region is depleting.
Answer:
c. neutrophils
Explanation:
The main characteristics of neutrophils that made them different from other white blood cells is the multi-loped structure of nucleus in neutrophils.
Also neutrophils are different from other white blood cells as they are professional phagocytes and they respond by phagocytosis of microbes during the immune response.
