Answer:
Weathering, Erosion
Explanation:
Plants and animals can be agents of mechanical weathering. The seed of a tree may sprout in soil that has collected in a cracked rock. As the roots grow, they widen the cracks, eventually breaking the rock into pieces. Over time, trees can break apart even large rocks.
Tree root systems have a handful of large roots that branch out into a network of smaller roots that often extend out far beyond their branches do. These root systems prevent erosion by holding the soil in place and improving drainage which helps water get absorbed into the soil instead of just running over the top.
Hope this helps

Explanation:
The Sun does not heat Earth evenly. Areas at different latitudes receive a varying amount of direct sunlight.
Would a city located at 70°N latitude have a warmer or colder climate? Why?
examples of changing direction?
Answer:
All changes in motion (speed or direction) need an outside cause. Other examples would be a soccer player kicking a moving soccer ball so it changes direction, or a hockey player hitting a sliding puck with his stick so as to redirect it.

Which air mass brings high temperatures and precipitation to Gwinnett County in late spring?
Answer:
Climate of Georgia. Maritime tropical air masses dominate the climate in summer, but in other seasons continental polar air masses are not uncommon.
Explanation:
Which of the following are made mostly or entirely of proteins? (Select all that apply.)
fats
body tissues
carbohydrates
hormones
I think the answer is body tissue
Answer:
Body tissues/hormones
Explanation:
Excluding water and fat, the human body is made up almost entirely of protein. Protein is the main component of muscles, bones, organs, skin, and nails. Excluding water, muscles are composed of about 80% protein, making this nutrient especially important for athletes.
1) Protein hormones (or polypeptide hormones) are made of chains of amino acids. An example is ADH (antidiuretic hormone) which decreases blood pressure. 2) Steroid hormones are derived from lipids.

Some animals migrate, or seasonally move to a different place. In some bird populations, such as Canada geese, some birds migrate and some stay in the same area year-round. Migration can enhance the survival of individuals because it —
exerts a lot of energy.
How many atoms of Br are there?How many atoms of Br are there?
Answer:
8
Explanation:
There are 8 atoms of Br because there are two molecules of 4 atoms of Br. 4 x 2 = 8.
Answer: 1 mol Br contains 6.022×1023Br atoms;its mass is 79.90 g.
Explanation:
: I mole or bromine refers to 6×10^23 molecules of bromine. But 1 molecule of bromine has 2 atoms. Hence the atom count will be exactly twice.

How are electromagnets temporary?
A.) They are only magnetic when an electric current runs through them.
B.) They are only magnetic when a gravitational wave runs through them.
C.) They are only magnetic when near a lodestone.
D.) They are only magnetic for two weeks.
Such magnets are called temporary magnets. An electromagnet is a temporary magnet. It is made by winding a coil of insulated wire round a soft iron core. When a current is passed through the coil, the magnetic field produced by the current magnetises the soft iron core. The soft iron core loses all the magnetism when the current is switched off.

How do air masses flow?
from regions of low pressure to high pressure
it depends on the time of the day
from regions of high pressure to low pressure
whichever way the wind blows
How do air masses flow?
from regions of high pressure to low pressure
.
In general, cold air masses tend to flow toward the equator and warm air masses tend to flow toward the poles.
