Why do you think Europeans—and especially the English—are most affected by asthma?
Answer: Asthma is one of the most frequent chronic conditions in Europe, affecting more than 30 million Europeans – a number that is still growing.
"At some stage in the future almost half of the population may suffer from an allergic disease and asthma will be a considerable proportion of this," said Nikolaos Papadopoulos, professor of allergy and pediatric allergy at the University of Athens, in an interview. He added that it is also a global phenomenon.
Asthma is a chronic disease of the airways that makes breathing difficult. An asthma attack inflames and narrows the airways that carry oxygen to the lungs, leading to coughing, wheezing, shortness of breath, and chest tightness. Its prevalence has been linked to industrial development.

Which is NOT one of the four fundamental forces in the universe?
Electromagnetism
Strong
Gravity
Mass
Answer:
Mass
Explanation:
From walking on the street, to launching a rocket into space, to sticking a magnet on your refrigerator, physical forces are acting all around us. But all the forces that we experience every day (and many that we don't realize we experience every day) can be whittled down to just four fundamental forces:
Gravity.
The weak force.
Electromagnetism.
The strong force.
These are called the four fundamental forces of nature, and they govern everything that happens in the universe.
Air at the equator is warm and has a ______density, which creates ________ in comparison to the air at the poles.
Answer:
Lower, low pressure
Explanation:
The temperature at equator are mostly higher than at the poles almost all times of year. This high temperature causes air at the equator to warm up quickly and thus, the air density reduces and it becomes lighter. Now, light air rises upwards. Thus, creating a low pressure region at equators. This low pressure causes the air near the poles gush towards the equator.
Hence, the blanks will be filled with the words
Lower, low pressure.
Contrast the contraction of the a disease by the environmental, heredity/genetic and pathogenic pathways.
Answer:
Explanation:
Contraction of a disease by the environment, the environment is said to influence something certain traits either by amplifying them or prevent them from being expressed. Some disease tends to strive in environment that is favorable while some disease don't find expression where the environment is not conducive even though they are presents in the gene of the individual. Environment could include family, area where the individual lives, food, peer
While Contraction of disease that are heredity/genetic and having pathogenic pathways is high this is because any disease that is hereditary can be passed to successive generation through the inheritance of such gene from the parents this increase the likelihood of reoccurrence of such disease in a family where the parents has it.

Explanation:
bicycle tyres become flat when the weather is cold.Why?
Answer:
The tires lose air pressure in the winter because it contracts. If you have 35 lbs in the summer, with 85 degrees, when it gets cold, down to -10, your air pressure can get down to about 25 lbs. So before it gets bitter cold, inflate your tires up a little. You don’t want to be putting air in your tires once it is freezing out. Sometimes the schrader valve doesn’t seat properly because of frost and the rubber seal is hard. I have had several tires go flat on me because of this.

How is Uranus similar to Jupiter?
It has rings.
It has no moons.
It has a rocky surface.
It has methane in its atmosphere
.
Uranus and Jupiter both have rings, both have moons, but they are mostly gas planets, and both have some methane. I think id.k if that helped
Uranus is similar to Jupiter in that it has methane in its atmosphere. Therefore, the correct option is D.
What are Uranus and Jupiter?Both Jupiter and Uranus are planets in our solar system. Jupiter, the largest planet in our solar system, is located five planets from the Sun. Uranus, the third largest planet in our solar system, is located at a distance of seven planets from the Sun.
Both planets are gas giants, with atmospheres composed mostly of hydrogen and helium. Their upper atmospheres also include methane gas, which gives them a blue-green colour. However, there are many differences between Uranus and Jupiter. Although they are much less noticeable than Saturn's rings, Uranus has a system of rings and at least 27 moons. Compared to Jupiter, Uranus is smaller and has less mass.
Therefore, the correct option is D.

Explain the various phase of menstrual cycle with reference to changes in ovary and uterus and hormonal cycle.
Answer:
In the follicular phase, the follicles grow inside the ovary. The ovulatory phase is the time of greatest fertility for women. In it, estrogen levels peak just before the egg is released. In the luteal phase, after ovulation the follicular structure that remains in the ovary reorganizes and becomes a gland known as the corpus luteum. The self-determined life of the corpus luteum causes it to degenerate after 14 days and end a menstrual cycle. At the end of the luteal phase, progesterone and estrogen levels drop and menstruation occurs.
Explanation:
The follicular phase is where follicles develop (fluid-filled cavities in the ovary that contain an undeveloped egg) that will eventually house the egg. For the development of follicles, the body sends a signal to the brain to start the production of follicle stimulating hormone (FSH), the follicles begin to develop and produce estrogen. In the ovulatory phase, the level of estrogen in the body continues to rise, causing a rapid rise in LH. This increase causes the secretion of proteolytic enzymes that will degrade the follicular tissue allowing the maturation process of the ovum and its release to finish, a fact known as "ovulation". Ovulation usually occurs between 24 and 36 hours after the LH surge, so luteinizing hormone is a good factor for measuring the period of maximum fertility and knowing the fertile days of the woman. In the luteal phase, the corpus luteum develops that will last until a possible pregnancy or menstruation occurs, starting the next cycle. The egg, after being released, travels through the fallopian tube to the womb. It can survive up to 24 hours and sperm up to 5 days inside the uterus, therefore the days before ovulation and the day of ovulation itself, which can be calculated with the ovulation calendar, are those of maximum fertility and higher chances of pregnancy. After ovulation, the follicle begins to contract but continues to produce progesterone and begins to produce estrogen in order to continue preparing the uterus to receive the embryo.
