Answer:

Most planets discovered using the transit method have large diameters because planets having large diameters results in a more pronounce (noticeable) dimming effect during their transit between a star and an observer and are therefore readily discovered using the transit method than planets that have a smaller diameter

Explanation:

The transit method involves the detection of a transit (dimming) during the motion of an object between a star and an observer such as the motion of Mercury or Venus between an observer on Earth and the Sun

A large planet gives a higher dimming effect than a small planet and they are therefore more easily detectable using the transit method

The transit method is the method used to discover most of the known exoplanets which are planets that revolve around a star which is not the Sun

As the planet transits in front of a star in an observer's line of sight, it results in the dimming of the stars light by an amount equivalent to the ratio of the planet's to the star's circular areas

Example of planets discovered using the transit method includes the planet HD209458b.

Sickle cell trait is not a disease; it is an inherited red blood cell condition that can affect athletes at all levels. While sickle cell trait is not a barrier to playing competitive sports, athletes with sickle cell trait have experienced significant physical distress, including collapse and death during intense exercise. Heat, dehydration, inadequate acclimatization, altitude and asthma can increase the risk for medical complications in athletes with sickle cell trait Through awareness, education and proper physical conditioning under the supervision of a primary athletics health care provider, athletes with sickle cell trait may safely achieve outstanding athletic performance

What is the flow of molecules in passive transport?

Vilka [71]

Answer:

Active transport moves molecules against their concentration gradient, from an area of low concentration to an area of high concentration.

You decide to boil water to cook noodles. you place the pan of water on the stove and turn on the burner.

ziro4ka [17]

A. As the pan of the water is heated, the water molecules moves faster and father apart.
As the water is heated, the water molecules gains more kinetic energy as the result of the heat that is been added by the stove. The gained kinetic energy allows the molecules to move faster and to move father away from one another.
b. If there are more water inside the pan, the same phenomenon experienced in the [a] above will still occur, but this time around it will take a longer period for the reaction to occur. This is because, there are more water particles in the pan and therefore it will take longer time before the heat from the stove circulate round all the particles.

Tratando-se sobre atividades aeróbias, segundo Cooper (1972), qual das alternativas abaixo não está correta? a) Aumento da efici

Answer:

Diminuição do colesterol bom (HDL), aumento do colesterol mal (LDL)

Explanation.

Esto debe revertirse, debe ser una disminución del colesterol malo y un aumento del colesterol bueno.

Básicamente, el ejercicio aumenta el HDL y reduce los triglicéridos. En condiciones normales, los ejercicios aeróbicos no reducen el LDL. Sin embargo, cuando se combina con cambios en la dieta y una pérdida de peso bien controlada, el efecto combinado podría reducir el LDL.

En las condiciones estándar, el ejercicio recomendado por semana es de 150 minutos de ejercicios suaves o 75 minutos de ejercicio vigoroso por semana.

Por lo tanto, cuando se calcula por semana, esto sería un promedio de 20 minutos de ejercicio por día.

Andar en bicicleta, caminar, hacer jardinería y aeróbicos acuáticos son ejemplos prácticos de ejercicios leves o moderados que podrían aumentar el HDL. Sin embargo, el baile aeróbico, el trote y el salto de cuerda son ejemplos de ejercicios vigorosos que, cuando se combinan con la dieta y la pérdida de peso, conducen a una disminución del LDL.

This should be reversed, it should be a decrease in bad cholesterol and an increase in good cholesterol.

Basically, exercise boosts the HDL and lower triglycerides. Under normal conditions, Aerobic exercises do not reduce LDL. However, when combined with dietary changes and well-monitored weight loss the combined effect could lower LDL.

Under the standard conditions, the recommended exercise per week is 150 minutes of mild exercises or 75 minutes of vigorous exercise per week.

Therefore, when calculated per week this would be an average of 20 minutes of exercise per day.

Biking, walking, Gardening, and water aerobic are practical examples of mild or moderate exercises that could boost HDL. However, Aerobic dancing, jogging, and rope jumping are examples of vigorous exercises which when combined with dieting and weight losses leads to a lowering of LDL.
