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.

In order to improve their recovery after an intense workout many high-level athletes do "cool downs" to slow their movements, eat a snack, and breathe deeply. What choice below accurately explains how these steps aid cellular respiration?
Group of answer choices
By breathing in deeply and eating a snack, the athlete is able to take in more oxygen and sugar, which allows their cells to produce ATP energy through cellular respiration
Cooling down in this way allows them to take in more carbon dioxide and water which allows their cells to produce energy through cellular respiration.
Breathing deeply and eating a snack releases more carbon dioxide and sugar which are needed to perform cellular respiration.
Eating a snack takes in ATP energy which is then converted to sugar which is needed by the body to produce oxygen to begin cellular respiration.

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:
List 2 air masses and state what type of weather they cause.
Answer:
Maritime air masses form over water and are humid. Continental air masses form over land and are dry. Therefore, an air mass that develops over northern Canada is called a continental polar air mass and is cold and dry. One that forms over the Indian Ocean is called a maritime tropical air mass and is warm and humid.

Tree roots speed up ____ by creating and widening cracks in rocks! Tree roots slow down ____ by holding sediments in place so they're not transported away as quickly.
Answers to pick:
1) Weathering, erosion
2) Erosion, weathering
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

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 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 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.
