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.

How are tropical rain forests and temperate forests different?
There are two types of rainforests, tropical and temperate. Tropical rainforests are found closer to the equator where it is warm. Temperate rainforests are found near the cooler coastal areas further north or south of the equator. The tropical rainforest is a hot, moist biome where it rains all year long.

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:
Weather has a pattern so A is not the answer and no way Meteorologists would keep information to themselves so not B and lastly it's not impossible but just very hard so C is out, which leaves 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.

¿de que manera el desarrollo cientifico y tecnologico repercute en la agricultura ecologica ,como parte de las condiciones para la propuesta de emprendimiento familiar?
Answer:
Los desarrollos científico-tecnológicos han impactado positivamente sobre los sistemas de agricultura ecológica y en última instancia también sobre la agricultura familiar
Explanation:
La agricultura ecológica refiere a los procedimientos de explotación agrícola basados en la utilización sustentable de los recursos de la tierra y los métodos de fertilización orgánica, respetando el ambiente natural y evitando el uso de compuestos químicos artificiales (como por ejemplo plaguicidas químicos) y de cultivos transgénicos. Por otra parte, la agricultura familiar refiere a un tipo de agricultura ecológica basado en la dirección y la administración familiar. La agricultura familiar es el sistema de agricultura predominante en regiones pobres de América Latina y el Caribe, representando aproximadamente el 80 % de la producción agrícola. De este modo, el desarrollo de métodos eficientes de agricultura/ecológica familiar resultan fundamentales para lograr la seguridad alimentaria en la región y también para mitigar los efectos negativos del cambio climático. En este contexto, diferentes avances científico-tecnológicos han impactado positivamente sobre el manejo, eficiencia y productividad de la agricultura familiar como sistema de cultivo no sólo sustentable sino también eficiente, entre los cuales se destacan el desarrollo de mini-invernaderos, variedades mejoradas obtenidas a través de técnicas de mejoramiento genético convencional (selección a campo), trampas artesanales para la captura de insectos plagas, etc. Diferentes tecnologías/metodologías como las anteriormente citadas han sido ajustadas y validadas a partir de procesos de experimentación participativa con el objetivo de estudiar cuales son las condiciones de la zona que mejor se adaptan al tipo de cultivo y de incrementar la productividad de sistemas de cultivos sustentables.

The first Adrick agricultural species to be altered by genetic modification words though soybean be right
Answer:
Tomato.
Explanation:
Tomato is the first Adrick agricultural specie to be altered by genetic modification in order to increase the productivity. Soybean and many other plants also changed by doing modification in their genes which enhances the productivity as well as the quality of these plants. Genetic modification helps us to increase the yield of food crops in order to feed the existing population so we can conclude that genetic modification be done to achieve higher productivity of crops.

Sophia discovered two objects in space with the help of her telescope. She noted down the characteristics of the objects in the chart below.
Which of these statements is most likely correct about Object 1 and Object 2 discovered by Sophia?
A. Object 1 is an inner planet and Object 2 is a comet.
B. Object 2 is an inner planet and Object 1 is a comet.
C. Object 1 is an outer planet and Object 2 is an asteroid.
D. Object 2 is an outer planet and Object 1 is an asteroid.
Answer:
C. Object 1 is an outer planet and Object 2 is an asteroid.
Explanation:
While inner planets can have moons, many moons are a more common feature of outer planets (ex. Jupiter has 79 moons, while Mars has 2). Plus, moons don't orbit asteroids or comets since moons are usually larger. This rules out any of the options involving Object 1 being an inner planet, comet, or asteroid. As for object two, both an asteroid or a comet would make sense as they both have irregular shapes. The only answer that has Object 1 as an outer planet is C. Also Object 1 has rings, which shows that it's an outer planet.

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.
