The carrying capacity was exceeded by the fly population as Food was abundant for the first four weeks of the experiment.The fruit flies were unable to survive in a laboratory setting. The carrying capacity decreased when no new food was added to the culture jars. Options B,D and E are correct.
What is the reason of choosing fruit flies ?
The reason of choosing fruit flies is because of their big growth rate along with the smaller life cycle.
The carrying capacity that is the fruit flies were able to multiply faster and faster because the food source that is the nutrition that was given to the flies was in big amount thus the cycle could continue.
Fruit flies are able to reach a limit of the growth rate when they are in natural habitat when they reach the artificial setting then they are not able to get into the same growth rate.
The carrying capacity decreased when no new food was added to the
culture jars. With time when the nutrition source that was being added to the jars got decreased the flies stopped growth rate and reached a declining number as well.

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.

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.

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.

How have the factors that trigger an asthma attack changed since the 1900s? As a researcher, how would you put together the clues given here to explain the emerging epidemic?
so if you look up things that can cause an asthma attack it will also show that viruses and bacteria are a cause. with asthma you lungs could already be inflamed as well as your air way wich makes it harder to breath. when you have c-19 it will inflame your lungs even more so it makes it even harder to breath given an asthma attack. more asthma attack now are probably caused by c-19 because it is all over the place and the percent of asthma attack by virus has dramatically increased.
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.

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.

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.
