The fish is the  first organism that would be tested and measured for DDT as it pass on the DDT to the upward trophic level in food chain. After that predators will be checked for DDT concentration.

Explanation:

DDT level in the organism gets increase as it moves upward in the trophic level.

Toxins as DDT gets incorporated to fats and tissues of the organism. It gets soluble in fats.

The highest concentration of DDT is observed in tertiary consumers as carnivore.

It can be seen that DDT concentration is more in producers than primary consumers. With the process of biomagnification the concentration of DDT increases at successive levels.

In aquatic food chain pesticides or heavy metals are consumed by aquatic organsims which are consumed by large birds and human. The DDT level will be checked in fish then birds and humans.

satela [25.4K]

Answer:

The partial pressure of argon in the jar is 0.944 kilopascal.

Explanation:

Step 1: Data given

Volume of the jar of air = 25.0 L

Number of moles argon = 0.0104 moles

Temperature = 273 K

Step 2: Calculate the pressure of argon with the ideal gas law

p*V = nRT

p = (nRT)/V

⇒ with n = the number of moles of argon = 0.0104 moles

⇒ with R = the gas constant = 0.0821 L*atm/mol*K

⇒ with T = the temperature = 273 K

⇒ with V = the volume of the jar = 25.0 L

p = (0.0104 * 0.0821 * 273)/25.0

p = 0.00932 atm

1 atm =101.3 kPa

0.00932 atm = 101.3 * 0.00932 = 0.944 kPa

The partial pressure of argon in the jar is 0.944 kilopascal.

What will happen if atom hit earth with speed of light?​
xz_007 [3.2K]

Answer:

Every object that travel at the speed of light gains infinite mass. Is a law in physics that as it gains speed, it is gaining mass. Then, not is necesary that a meteorite hit the Earth at the speed of light, because just an atom traveling a this velocities could destroy our planet.

Explanation:

The speed of light is really fast so that will mostly happen
