An air mass forms over the North Pole region describe what you think the temperature and humidity of this air mass will be like?
Answer: hope this helps :)
The motion of air mass motion is usually based upon the air flow in the upper atmosphere. As the jet stream changes intensity and position, it affects the motion and strength of air masses. Where air masses converge, they form boundaries called "fronts".
3-D view of a cold front.
Fronts are identified by change of temperature based upon their motion. With a cold front, a colder air mass is replacing a warmer air mass. A warm front is the opposite affect in that warm air replaces cold air. There is also a stationary front, which, as the name implies, means the boundary between two air masses does not move.
The motion of air masses also affects where a good portion of precipitation occurs. The air of cold air masses is more dense than warmer air masses. Therefore, as these cold air masses move, the dense air undercuts the warmer air masses forcing the warm air up and over the colder air causing it to rise into the atmosphere.
So, fronts just don't appear at the surface of the earth, they have a vertical structure or slope to them as well. Warm fronts typically have a gentle slope so the air rising along

Why does mature soil contain the why does mature contain most humus?
a. Has the least decomposed organic material from trees and vegetation
B The mature soil has the most soil horizons
C The mature soil has the biggest layer of bedrock
D. Has the most decomposed organic material from trees and vegetation
Answer:
D. Has the most decomposed organic material from trees and vegetation
Explanation:
Mature soil has the most decomposed organic material from trees and vegetation. Therefore, option D is correct.
What is matured soil?A soil that has completed all the developmental phases and becomes stable when the addition of organic material becomes equal to the withdrawal of soluble minerals by the plants.
They are formed from rocks through the process of weathering and erosion. These processes take place by the wind, water, living organisms, pressure, change in temperature, and chemical reactions. There are three layers present in the mature soil and that are topsoil, subsoil, and parent rock. These layers are known as horizon.
Thus, mature soil consists of the most decomposed material from trees and vegetation. Therefore, option D is correct.

If you had a gram of water and a gram of oxygen, which substance would you have more particles of? Why?
The substance that will have more particles is 1 g of oxygen.
Avogadro's hypothesis 1 mole of water = 6.02×10²³ particles 1 mole of oxygen = 6.02×10²³ particlesBut
1 mole of water = 18 g1 mole of oxygen = 16 gTherefore,
18 g of water = 6.02×10²³ particles 16 g of oxygen = 6.02×10²³ particlesHow to determine the particles in 1 g of water18 g of water = 6.02×10²³ particles
Therefore,
1 g of water = (1 × 6.02×10²³) / 18
1 g of water = 3.34×10²² particles
How to determine the particles in 1 g of oxygen
16 g of water = 6.02×10²³ particles
Therefore,
1 g of oxygen = (1 × 6.02×10²³) / 16
1 g of oxygen = 3.76×10²² particles
SUMMARY 1 g of water = 3.34×10²² particles 1 g of oxygen = 3.76×10²² particlesFrom the above, we can conclude that 1 g of oxygen contains more particles than 1 g of water

How might evidence from an experiment such as this help shape Darwin’s ideas about evolution?
Explanation:
Darwin, is a brilliance ahead of his time.
He has proven evolution by his observations in the field. EXAMPLE/
He started with plants..a control group & experimental plants he grew himself. After that, he has proven, (evolution theory with environmental variances determines how animals adapt to a new environment)... it is not possible to grow a tropical plant in the midwest without warmth, humidity, water etc...
He had proven through his observations that giraffes have long necks so they can reach the higher branches of food while living in arid climates.
While his counterparts disagreed, he had visited these places worldwide 2 study this.

Explanation:
Hope it helped <3
The role of control in an experiment is to minimize the effects of factors.
Scientific control is an experiment in which a subject (or a group of subjects) is not tested for a dependent variable (or variables). The addition of control to an experiment is essential for obtaining the results of the empirical data.
A control variable is a variable that is held constant throughout a study. It is not a study variable, but it is controlled because it has the potential to affect the study results.
It is used for comparisons to confirm the results of an experiment. It is used to guarantee that the measured dependent variable is influenced only by the changed independent variable and not any other variables (controls) in the experiment.

Complete the sentence. The ________________ of extra rabbits into a forest ecosystem can affect the population of other herbivores already living there.
- birth rate
- death rate
- emigration
- immigration
The immigration of extra rabbits into a forest ecosystem can affect the population of herbivores living in the forest.
What is immigration?Immigration is the movement of people or animals from external locations into a population.
With new individuals moving into a population, the population size increases with other factors being constant.
With the increase in the population size, competition for resources increases accordingly.
Thus if extra rabbits move into a forest ecosystem, the population of herbivores existing in the ecosystem would be affected because competition for food would increase.

Which of following has the least ecological tolerance to climate change?
- Small island close to the mainland
- Small island far away from the mainland
- Large island close to the mainland
- Large island far away from the mainland
Given what we know, we can confirm that a small island far away from the mainland is the least tolerant to climate change.
Why is this the case?A small island far away from the mainland is less tolerant of climate change from an ecological viewpoint than the other options listed. This is the case because of the size and location of the lsland. A small faraway island does not have many options for the wildlife to migrate or adapt and is therefore more intensely affected by any changes in climate.
Therefore, we can confirm that a small island far away from the mainland is the least tolerant to climate change.
