Answer:
they help it thrive and live because it just goes in a circle sun grows plants plants feed herbivores, herbivores feed omnivores then it eventually gets to the top of the food chain and when the top of the food chain dies it decomposes and gives the ground fertilizer and starts all over again
Explanation:
because it is the circle of life
Answer:
It has 0.82 moles of gas
Explanation:
Given:
The Volume of gas = 30 L
The pressure of the gas = 0.7 atm
Temperature =315 K
To Find:
Number of moles of the gas = ?
Solution:
According to Ideal gas law
PV =nRT
where
P is the pressure
V is the volume
T is the temperature
n is the number of moles
R is the gas law constant
On substituting the given values in the formula, we get
(0.7) (30) = n (0.0817)(315)
21 = n (25.7355)
n = \frac{21}{25.7355}
n= 0.8159
n = 0.82(rounding off)
Answer: To introduce nitrogen back into the soil you can plant crops that create their own nitrogen like soybeans and other legumes crops or use a chemical fertilizer with nitrogen in it. Crop rotation is also a eco effecieint way for farmers to reduce the risk of nitrate leaking onto the surface.
Explanation:
Each protein has its unique sequence and number of amino acids. This determines their 3-D structure as well. The properties of the protein are also attributed to the unique sequence and number of amino acids present in it. Different sequence and number denote that the two proteins are different, and have different structure and properties.
<span>Answer: optio b. Healthy ecosystems. The other three options design trheatens on biodiversity because invasive species, climate change and pollution may kill many species that cannot adapt to a sudden change and will benefit a reduced number of species that can adapt and survive. Healthy ecosystems promote biodiversity, so it is a value.</span>
