Which statement describes global winds?
They flow from the same direction.
They travel over short distances.
They generate land breezes.
They blow away from the poles to the equator.
Answer:They blow away from the poles to the equator.
Hope this helps
The statement that describes global winds is: "They blow away from the poles to the equator."
What are Global winds?Global winds are large-scale winds that circulate around the Earth in a predictable pattern. These winds are caused by the unequal heating of the Earth's surface by the sun, which creates differences in air pressure and causes air to move from areas of high pressure to areas of low pressure.
The Coriolis effect, caused by the Earth's rotation, causes these winds to curve as they move, creating patterns such as the trade winds and prevailing westerlies.
In general, the global wind pattern moves warm air away from the equator and towards the poles, while cooler air moves towards the equator to replace it. This creates a system of atmospheric circulation that plays an important role in regulating the Earth's climate and weather patterns.
Understanding the global wind patterns is important for a range of fields, from aviation and shipping to weather forecasting and climate modeling.
These winds play a major role in determining weather patterns, ocean currents, and climate zones, and can also affect the distribution of pollutants and other particles in the atmosphere.

a skaterboarder is traveling 12 m/s down a hill. The skaterboarder cradshed and slid to a stop in 2.0 seconds. What was the rider's acceleration?
PLEASE!!!
The skateboarder is travelling with a initial velocity of 12 m/s and slid to stop in the next 2.0 seconds. The acceleration of the skateboarder will be -6 m/s².
What is Acceleration of an object?Acceleration of a body is the change in the velocity with respect to time. Acceleration depends upon factors such as time, initial velocity, final velocity, and distance travelled by the object.
In the given question, the skateboarder is travelling with a initial velocity (u) of 12 m/s
Time (t) after which he comes to a stop is 2.0 seconds
The skateboarder stops and comes to rest therefore, the final velocity (v) of the skateboarder will be zero
The acceleration (a) of the skateboarder can be calculated by the formula:
a = (v - u)/t
where, a = acceleration of the object
v = final velocity of the object
u = initial velocity of the object
t = time elapsed
a = (0 - 12)/2.0
a = -12/2.0
a = -6.0m/s²
Here, the acceleration is negative because the body comes to rest at the end after acceleration.

Which choice is NOT a characteristic of all cells? *
all cells have a cell membrane
all cells have a cell wall
all cells contain genetic material (DNA)
O all cells have cytoplasm
Answer:
I think it would be all cells have a cell wall
Explanation:
all cells have a cell membrane but not a cell wall
The choice that is not characteristic of all cells is the presence of a cell wall. So the correct option is B.
What is a cell wall?
The non-living material that protects a cell's outermost layer is referred to as its cell wall. According to the organism, its composition changes, and it is porous by nature. The cell wall isolates the inner elements from the surrounding environment. Additionally, it gives the cell's organelles structure, support, and safety. But only eukaryotic plants, fungi, and a few prokaryotic creatures have this cellular component.
Fungi also have cell walls, but they are made of chitin, a glucose derivative found in the exoskeletons of arthropods. Similar to plant cell walls, they also provide structural support and protect against desiccation.
Bacteria and other prokaryotic creatures have cell walls as well. They differ chemically from the cell walls found in plants and fungi, though. Peptidoglycans are substantial polymers found in bacterial cell walls.
Eukaryotic cells have a unique nuclear membrane and a distinct nucleus. Additionally, it has membrane-bound organelles that are absent from prokaryotic cells. Another significant distinction is that only plants have cell walls; other eukaryotic creatures, such as animals, have not.
Therefore the correct option is B.

Why do some stars become red supergiants?
Answer:
Eventually, as stars age, they evolve away from the main sequence to become red giants or supergiants. The core of a red giant is contracting, but the outer layers are expanding as a result of hydrogen fusion in a shell outside the core. The star gets larger, redder, and more luminous as it expands and cools.

A student is measuring the lengths of caterpillars for an experiment. She measures 100 caterpillars using a ruler that measures to the nearest centimeter. Which statement describes a change that could help improve the results of her experiment? O A. Her measurements will be more precise if she measures an additional 100 caterpillars. O B. Her measurements will be more accurate if she measures an additional 100 caterpillars. O C. Her measurements will be more accurate if she uses a ruler that measures to the nearest millimeter. O D. Her measurements will be more precise if she uses a ruler that measures to the nearest millimeter Please help
Answer:
B and C
Explanation:
The student's measurement would be more accurate if she can measure an additional 100 caterpillars and be more precise if she uses a ruler that measures to the nearest millimeter.
Accuracy refers to the closeness of measurement or group of measurements to the true value while precision is the closeness of repeated measurements.
The accuracy of a measurement is increased by increasing the number of sample measurements. The more the sample measurements, the lesser the deviation of the mean from the true value.
The precision of a measurement is increased by being able to measure small differences. Hence, a ruler that measures to the nearest millimeter would be more precise than a ruler that can only measure in centimeter.

Most earthquakes are not strong enough to be felt by human.
Answer:
the answer is 5 and 3 i had a question like this and i got it right i hope im right
Explanation:
About 100 earthquakes per year are strong enough to cause damage, while most earthquakes are not strong enough to be felt by humans. So, the correct options are (D) and (E).
What is Earthquake?An earthquake is defined as a sudden release of strain energy in the Earth's crust which results in waves of vibration that radiate outward from the earthquake source. When the stress in the crust exceeds the strength of the rock, it tends to break along lines of weakness, either pre-existing or new fault planes.
Earthquakes occur very frequently as the Earth's tectonic plates are always move and they collide or brush against each other which creates stress that is regularly released in the form of earthquakes. About a million earth tremors occur every year that are undetectable to humans, where they are 2.4 on the Richter and lower in magnitude. Therefore, every year there are about 100 earthquakes above 6.0 Richter magnitude that cause damage.
Thus, about 100 earthquakes per year are strong enough to cause damage, while most earthquakes are not strong enough to be felt by humans. So, the correct options are (D) and (E).
