Moderna is very effective. studies carried out by New York researchers suggests that both Pfizer-BioNTech and Moderna, are 94 to 95 percent effective in preventing the virus from delta
Answer:
Most correct answer is all of the germ layers
Explanation:
Mucous membranes constitute the innermost layer of a number of hollow organs (i.e.: gastrointestinal tract). They are composed of an epithelial lining which overlies a deeper layer of connective tissue. Typically, each of these components arises from a different germ layer. For instance: the mucous lining of the gut arises from a combination of endoderm-derived epithelium and lateral mesoderm-derived connective tissue. Other mucous membranes may have different origins, for example: The mucous lining of the oral cavity is composed of ectoderm-derived epithelium and underlying connective tissue derived from head mesenchyme (combination of cephalic neural crest and paraxial mesoderm).
Summary:
Mucous Membrane = Epithelium (derived mainly from endoderm, followed by ectoderm, rarely mesoderm) + Underlying Connective Tissue (usually mesoderm)
Answer:
C, both A and B
Explanation:
A salmonella infection is an infection in the intestinal track. Some of the sources of the infection are contaminated water and food, meat, fertilizer and pets.
Symptoms of salmonella include abdominal pain with cramps, diarrhea, vomiting with accompanying nausea. Some people also experience chills and fever.
The illness usually goes away on its own but some patients may need hospital treatment.
Prevention of salmonella include hand washing, cooking well of all foods and avoiding contact with unknown animals.
Answer: This is TRUE for me. Osteoporosis is a preventable disease.
Explanation:
In this condition, bone density ( the amount of bone tissue) is reduced because it's deposition does not keep pace with resorption. Although the bone is adequately mineralised, it is fragile and microscopically abnormal, with loss of internal structure.
Peak bone mass occurs around 35 years and then gradually declines in both sexes. Lowered oestrogen levels after the menopause are associated with a period of accelerated bone loss in women. Thereafter bone density in women is less than in men for any given age. That is why in North America, one-third of all women experience fractures because of this disease, amounting to about 2 million bone fractures per year.
Common features of osteoporosis are:
--> skeletal deformity: gradual loss of height with age, caused by compression of vertebrae.
--> bone pain
--> fractures: especially of the hip ( neck of femur), wrist and vertebrae.
It is TRUE for me that some risk factors can't be changed ( which is the low oestrogen levels that occur after menopause in women) but others, such as poor calcium intake, can.
Exercise and Calcium intake during childhood and adolescence are important in determining eventual bone mass of an individual and in preventing risk of osteoporosis in later life.
Please be rightly informed that different research laboratories have different ways of measuring impulsivity simply because respective research centres have different means of measuring the impulsivity of drugs or substances.
<h3>Research laboratory</h3>
A research laboratory is simply a testing center where scientific investigation, observations and experimental analysis are made.
A research laboratory must be free of biase Informations and results given by research centres must be verifiable by other centers
So therefore, please be rightly informed that different research laboratories have different ways of measuring impulsivity simply because respective research centres have different means of measuring the impulsivity of drugs or substances.
