Answers
The concentration gradient is the probability of where ions will go freely to try and make the concentration the same in each part of the cell. When ions want to cross into the membrane, most of them will have to go against the concentration gradient and will use energy to do so!

1. How do you think rapid changes in the chracteristics of habitats affect the niches of
animals occupying that habitat?
Answers
Answer:
The rapid changes would make an organism change their land, environment around them, and the food web
When the habitat of the animals living in it changes, both the animals and the habitat change. It changes the biotic and abiotic factors of the niche and ecosystem. Habitat is part of a niche.
What is the impact of the changing habitat?
Niche is a broad space in which the particular animal roams, searches for food, and reproduces, but habitat is a part of the niche where the animal spends most of its life. Human interventions, such as cutting down forests for industry, roads, and so on, have an impact on wildlife. Due to this, the temperature of the earth keeps on increasing, resulting in climate change, global warming, the melting of ice, a rise in water levels, etc.
If these changes happen, then animals will have difficulty living in their habitat. The environment will not be favorable for living, and both abiotic and biotic factors will be disturbed, such as the fertility of the soil, which is affected by fewer trees. Other animals affect by this change too.
Hence, in this way, the change in habitat changes the niche.

how does air pressure affect weather
Answers
Answer:
Hewo, Kiluawa (sorry if i spelled it wrong)
Explanation:
High Pressure
Basically, high pressure occurs in an area if the atmosphere over that particular area becomes heavier. As a result, the heavy air above will come down to the Earth’s surface. And the air present in that area will move away to create space for the heavy air.
Commonly, the warmer months experience high pressure. You’re more likely to enjoy a comparatively dry and stable weather pattern in those months. Besides, you’ll find the skies in high pressure areas very clear. You’ll also feel a gentle breeze there that will cool down the surrounding areas.
Low Pressure
On the other hand, the air above a low pressure area is comparatively much lighter than the air below. As the heavy air on the Earth’s surface cannot go further below, it pushes away the lighter air above. As a result, a vacuum is created on the surface level and the air in the surrounding areas rushes towards it to fill up the void space.
Meanwhile, the rising air starts to cool down and form clouds in the sky. These clouds then come down to the Earth in the form of rain. Sometimes, snow is also formed depending on the temperature of the surrounding areas.
In general, colder months of the year experiences more low pressure situations. By now, you probably can guess why. The cold air on the surface level is heavier than the air above. And these low pressure areas are the reasons behind unstable weather conditions like snow, ice, rain, storm, etc.

Group of answer choices
A. Full moon
B. New moon
C. Waxing gibbous
D. Waning crescent
Answers
Answer:
A, full moon
hope this helps ;)
In the full moon phase, the moon is completely visible from the Earth. Therefore, the correct option is A.
What are the phases of the moon?The phases of the moon results from the changing position of the moon relative to the Sun and the Earth.
There are 8 phases of the moon:
1.) New moon-The moon is between the sun and the earth, with its illuminated side facing away from us.
2.) Waxing crescent-The moon is partially illuminated increasing in size, appearing as a crescent shape.
3.) First quarter-The moon is 90 degree east of the sun and appears as a half moon shape.
4.) Waxing Gibbous-The moon appears as gibbous shape.
5.) Full moon-The moon is on the opposite side of the earth from the sun, and its entire illuminated side is visible.
6.) Waning gibbous-The moon is partially illuminated and decreasing, appearing as a gibbous shape.
7.) Third quarter-The moon is 90 degree west of the sun and appears as a half moon shape.
8.) Waning crescent-The moon is partially illuminated and decreasing, appearing as a crescent shape.
The cycle of phases repeats approximately every 29.5 days, from new moon to new moon. Therefore, the correct option is A.
