with 75% of their mass being hydrogen and 25% helium.
Celestial objects that are formed mostly of the elements hydrogen and helium are gas giants and dwarf planets. Gas giants are large planets, such as Jupiter and Saturn, which are composed primarily of hydrogen and helium.
What is the reason of calling them Jovian planets ?These planets are also known as Jovian planets, and they are much larger than the terrestrial planets, such as Earth, that are made up of rock and metal. Gas giants have no solid surface and are composed mostly of gas and liquid.
Dwarf planets are smaller than gas giants and are made up of a combination of rock and ice. These objects are too small to be considered full-fledged planets, but they still have characteristics of planets such as an atmosphere, moons, and an orbit around the sun.
Although these objects are composed of different materials than gas giants, they still contain significant amounts of hydrogen and helium. In contrast, rocky planets and asteroids are composed of materials such as rock, metal, and ice. Rocky planets, such as Earth, are composed mostly of iron, silicon, magnesium, and other elements
Hence, . Asteroids are small, rocky objects that are found in the asteroid belt between Mars and Jupiter. These objects are composed of rock, metal, and ice, and contain very little hydrogen and helium.

Which role do ultrafine particles play in dirty air?
They contribute to less than 13,000 premature deaths a year.
They can worsen symptoms for people with breathing difficulties.
They are easily removed from the air when people see them floating.
They are constantly filtered by the nose, which prevents lung absorption
Answer:
B
Explanation:
The role the ultrafine particles play in dirty air is that they can worsen symptoms for people with breathing difficulties. The correct answer is b).
What are ultrafine particles?The term "ultrafine particles" (UFPs) refers to particles with a dimension of less than micrometers and more than 0.1 micrometres (100 nanometers), also known as nanoscale particles. The majority of the ultrafine particles are found on motorways and are mostly produced by vehicle emissions.
It has been demonstrated that ultrafine pollution particles may play a crucial role in igniting extra pathways or inflammation, which worsens asthma disease. The ultrafine particles released by motor vehicles and other sources of combustion are covered with an organic chemical coating that can be inhaled.
By oxidizing cells and tissues, these substances create free oxygen radicals that activate the immune system in the lung. For those who have asthma, oxidation exacerbates the allergic inflammation in their lungs.
Therefore the correct option is b).

A student is sitting in class drinking a 16.9 fl oz bottle of Arizona tea (the size that you get from the deli). The student isn’t doing any activity, so the student’s body doesn’t need the sugar right away. What happens to all the sugar?
Answer:
The sugar is stored as glycogen in the students body
Explanation:
The food we consume contains sugar molecules (carbohydrate) that is broken down via respiration to synthesize energy (ATP). However, the sugar is not always utilized at once as the excess is stored as a carbohydrate called GLYCOGEN in our liver cells or muscle.
According to this question, a student is sitting in class drinking a 16.9 fl oz bottle of Arizona tea. The student, however, is not doing any activity and so his/her body does not need the sugar right away. This means that the body will store the sugar as GLYCOGEN until it is needed.

1. Normal red blood cells can barely squeeze through the capillaries (the tiniest blood vessels). What
problems might be caused by sickle-shaped red blood cells?
Sickle-shaped red blood cells would slow down or cause a blockage (blood clot) to the blood vessels further leading to attacks such as heart attacks.
This is due to the fact; the new shape would simply be unable to pass safely through the small blood vessels to perform its main purpose of transferring oxygen throughout the body.
Research the effect of insulin on blood sugar after a meal. You may use outside sources. Select the correct statement. Insulin has no effect on blood sugar. Insulin increases blood sugar. Insulin reduces blood sugar.
Answer:
Insulin reduces blood sugar.
Explanation:
Insulin is an hormone produced naturally in the pancreas organ of the body. Insulin is majorly involved in digestion where it helps in the absorption process. Insulin aids the absorption of glucose by cells.
When a meal is eaten, the food digests and breaks down into GLUCOSE, which enters into the blood stream via the small intestine. Insulin ensures that the sugar (glucose) content in the blood REDUCES by moving glucose into cells for respiration (energy production) and storing the excess glucose as glycogen in the liver cells.

A controlled experiment was conducted to analyze the effects of darkness and boiling on the photosynthetic rate of incubated chloroplast suspensions. The dye reduction technique was used. Each chloroplast suspension was mixed with DPIP, an electron acceptor that changes from blue to clear when it is reduced. Each sample was placed individually in a spectrophotometer and the percent transmittance was recorded. The three samples used were prepared as follows.
Sample 1 – chloroplast suspension + DPIP
Sample 2 – chloroplast suspension surrounded by foil wrap to provide a dark environment + DPIP
Sample 3 – chloroplast suspension that has been boiled + DPIP
On the axes provided, construct and label a graph showing the results for the three samples.

Answer: hello your question is in complete below is the complete question
A fiber reinforced composite contains e-glass fibers in an epoxy matrix. E for the glass is 72 GPA, E for the epoxy is 2.4 GPa. Find the elastic modulus of a composite that contains 5% fibers in the longitudinal direction, Ecl = ViEi + EmVm? (note Vi + Vm= 1.) O 5.88 GPa O 5.66 GPa O 2.52 GPa O 6.74 GPa
answer : 5.88 GPa
Explanation:
Fiber reinforced composite containing e-glass fibers
E for the glass ( Ei ) = 72 GPa
E for the epoxy ( Em ) = 2.4 GPa
Determine the Elastic modulus of a composite containing 5% fibers
percentage of glass = 5% = Vi = 0.05
∴ percentage of epoxy = 95% ; Vm = 0.95
using the relation included in the question
Ecl = Ei Vi + Em Vm
= ( 72 * 0.05 ) + ( 2.4 * 0.95 )
= 3.6 + 2.28 = 5.88 GPa
