Answer:
The pressure on the inner core puts the inner core into a solid state, therefore the temperature is hotter than the outer core, but not enough to melt a substance due to the pressure squeezing down from the other layers above.

Which best describes why active transport requires atp to move molecules across the cell membrane?
A. Molecules are moved with the concentration gradient
B. Molecules are moved against the concentration gradient
C. No net movement of molecules needs to occur
Answer:
B. Molecules are moved against the concentration gradient.
Explanation:
Due to the higher concentration of the molecules of one of the sides than the other,in order to move molecules from the side with higher concentration of molecules to the side of lower concentration of molecules which is against the movement of molecules across the membrane, energy must be applied i.e atp.
The reason active transport requires ATP to move molecules across the cell membrane is because molecules are moved against the concentration gradient.
ACTIVE TRANSPORT:
Active transport is a type of cellular transport that requires the input of energy in form of ATP. Examples of active transport are pumping of Na+/K+ ions, exocytosis etc. Active transport requires ATP because molecules are being moved against concentration gradient. This means that molecules are moved from regions of low concentration to that of high concentration. Passive transport, which does not require energy, moves molecules down a concentration gradient. Therefore, the reason active transport requires ATP to move molecules across the cell membrane is because molecules are moved against the concentration gradient.Learn more at: https://brainly.com/question/12133248?referrer=searchResults

Diabetes is often suspected when glucose shows up in urine tests. Use the model to explain how glucose could be present in urine. Why do you think this symptom is especially concerning for young people?
Answer:
S.A for Edmentum and Plato
Like and Rate
In step 1, blood goes to the kidney for filtration. If excess sugar exists in the blood, the filtered substances will have more sugar than they do in a person who doesn’t have diabetes. In step 2, there is some reabsorption of sugar. But if there’s an unusually high amount to filter, some sugar will stay in the urine as it passes through the renal tubule to be excreted by the body. This symptom is concerning because it could stress the kidney, which could lead to kidney problems at a young age.

Explain why volcanoes form at both convergent plate boundaries and divergent plate boundaries.
Answer:
Volcanoes often form along tectonic plate boundaries where oceanic plates sink beneath other plates. As a plate sinks deep into a subduction zone, it will start to heat and melt, forming something called magma. Volcanoes can also be created near tectonic boundaries where plates pull apart. This allows magma to rise up from the mantle.

Answer:
In an oceanic environment the photic zone is the zone where light can be received it's usually from 0 to 200 m deep but this depth can be modified by the turbidity of the water. The aphotic zone is the zone where no light is receives it goes from 200 to the bottom of the sea.

Clouds form when air is ? A) swirled by wind. B) heated by the sun. turned into ozone. D) transpired by plants.
Answer: transpired
Explanation: PLEASE GIVE BRAINLIEST IT HELPS ALOT
Answer: heated by the sun
Explanation:
When the Sun warms the Earth, warm air rises into the atmosphere. As it rises, it expands and cools. Water vapor condenses out of the cool air to form a cloud.
If distance=rate x time, which of the following must also be true?
A- rate= distance x time
B- time= distance/rate
C- distance= rate/time
D- time= rate/distance
If distance = rate x time
then,
Time = Distance/Rate
Hence, Option B is correct.
Time is directly proportional to distance.
What is meant by Rate?The ratio of two related numbers expressed in several units is known as a rate in mathematics. If one of these numbers is used as the ratio's denominator and it is assumed that this quantity may be modified in a predictable way (i.e., is an independent variable), then the numerator of the ratio represents the rate of change in the other (dependent) variable.Speed, heart rate, and flux are examples of common rates that are expressed as "per unit of time." Exchange rates, literacy rates, and electric field are a few ratios that don't need time as the denominator (in volts per meter).A rate that is defined using two numbers of the same units will provide a dimensionless quantity that can be stated as a percentage, fraction, or multiple. Examples of these rates include tax rates and literacy rates.To learn more about Rate, refer to:
