The correct descriptions that help to define luminosity are How much energy is emitted per second, How much surface area the object has, and The amount of brightness of an object.
What is the energy content of luminosity?An object's luminosity, which is the quantity of energy it emits over a predetermined period, is a measurement of its inherent brightness. Since it simply measures the object's power output, it can be expressed in units like Watts.
What factors affect luminosity?A star's luminosity, or the total amount of energy it emits each second, is determined by two factors: The stellar photosphere's "Effective Temperature," T. the star's total surface area, which is influenced by its radius, R.
What three things have an impact on luminosity?The size, temperature, and distance of a star are the three variables that determine how bright it seems to us on Earth. The brilliance of a star is measured by its magnitude.

a _____ force is when two forces cancel each other out and do not affect the motion of an object
Answer:
Friction and gravity are at work in each picture. Explain how each are at work and how they work together. Balanced forces - Two or more opposite forces are balanced forces if their effects cancel each other and do not cause a change in an object's motion.
Explanation:
Balanced forces are equal and opposite forces that act on the same object. That's why they cancel out. Action-reaction forces are equal and opposite forces that act on different objects, so they don't cancel out. In fact, they often result in motion.

Study the illustration below of the plate tectonics affecting the continent of Africa. Divergent plates are causing the East African Rift Zone to spread. This area is a deep valley surrounded by mountains, similar to a mid-ocean ridge. What do you predict will eventually happen at the East African Rift Zone?
African plate tectonics showing the Eurasian Plate, Arabian Plate, Indian Plate and African Plate (Nubian) and (Somalian). A rift zone is shown extending from the edge of the Arabian Plate through the Indian Plate and extending into the African Plate (Somalian).

Lake Victoria will shrink and disappear as all of the plates converge.
The African plate will grow larger as all of the plates converge.
Water from the Gulf of Aden and the Indian Ocean will flow into the rift and flood the area.
The Indian Ocean will shrink and disappear as the Rift Zone gets larger.
Answer:
C

The things that you will predict will eventually happen at the East African Rift Zone are the Water from the Gulf of Aden and the Indian Ocean will flow into the rift and flood the area. Thus, the correct option for this question is C.
What is plate tectonics?Tectonic plates are the types of crustal plates that are gigantic pieces of the Earth's crust and uppermost mantle. A crustal plate may be defined as a type of large block or tabular section of the lithosphere that significantly reacts to tectonic forces as a unit and moves as such.
The movement of the crustal plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways in relation to each other. Due to this, the water from the Gulf of Aden and the Indian Ocean will flow into the rift and flood the area.
Therefore, the correct option for this question is C.

What role do urban cities play in affecting albedo
Answer:
Urbanization has many effects on surface albedo. It reduces it through the introduction of dark surfaces, through changing the surface geometry to better capture solar radiation, and through reducing snow cover in winter. It can also increase it by increasing the cloud cover and by emitting air pollutants and aerosols.

1. Flowers must rely on vectors to move pollen. These vectors can include wind, water, birds, insects, butterflies, bats, and other animals that visit flowers. We call animals or insects that transfer pollen from plant to plant “pollinators”.
2. Germination:When a seed falls on the ground, it needs warmth and water in order to germinate; some seeds also need light. Dicots have seed coats that soften with moisture. After being planted in the soil for a few days, the seed absorbs water and swells until the seed coat splits.

diffusion. You are an educated Honors Biology student, and you believe
that he/she is incorrect in their claim. Make a claim as to which type of
cellular transport is represented in the image (1 point)State TWO pieces of
evidence from the image that supports your claim (2 points).*
Answer:
Facilitated diffusion is a type of passive transport of molecules down the concentration gradient between two sides of a membrane which doesn't require ATP and instead uses a specific transmembrane protein.
Active transport requires instead ATP and it is the process drawn in the figure. Moreover the figure illustrates that molecules are moving against their concentration gradient.

Greg Developed and Ear infection. His doctor gave him an antibiotic. The antibiotic killed all the bacteria in his body. What other effect could the antibiotic have
Some of the antibiotics doctors prescribe to treat an ear infection such as amoxicillin, cortisporin (neomycin/hydrocortisone) solution or suspension.
What is infection?The infection is invasion and growth of germs in the body. The germs can be bacteria, viruses, yeast, fungi, or other microorganisms. Infections can begin anywhere in the body and may spread all through it.
Antibiotics can have side effects as when children take antibiotics at the first sign of an ear infection, they are more likely to have vomiting, diarrhea, and allergic reactions because of the medicine. Also, antibiotics can kill “friendly” germs in the body and cause other problems like diarrhea.

Would collecting the resources that go into bread have long-term or short-term effects on the environment? Explain your answer.
Answer:
a short term effect. In their life cycle analysis, the researchers found that a loaf of bread emits about a half-kilo of carbon dioxide. Forty-three percent of bread's greenhouse gas emissions can be attributed to the fertilizers used to grow wheat
It is a short term effect. In their life cycle analysis, it has been observed that a loaf of bread emits about a half-kilo of carbon dioxide.
What's the Environmental Impact of a Loaf of Bread?The life cycle of a loaf o bread is started from growing, harvesting, and transporting to producing flour, shipping to a bakery, baking loaves and packaging them.
In the life cycle it has been found that per loaf of bread about a half-kilo of carbon dioxide is emitted where nearly 43% of bread’s greenhouse gas emissions can be used in the fertilizers for wheat cultivation.
Two-thirds of the emissions come from actual fertilizer production.
we are unaware of the environmental impacts of this products mainly concerned with human health or animal welfare.
It was found that each loaf production is associated with global warming as a result more amount of fertilizer applied in order to increase their wheat harvest.
