The answer is D. 3.33 A
In parallel connected devices, circuits are also placed parallel. It is known that in parallel circuits, total voltage is equal to the voltage of each device.
So, we know that:
Device 1 - R1 = 12 ohms
Device 2 - R2 = 4 ohms
Total voltage - V = 40V = V1 = V2
If V = I × R, for the first device is V1 = I1/R1.
⇒ I1 = V1 ÷ R1
⇒ I1 = 40 V ÷ 12 ohms
⇒ I1 = 3,33 A

Answer:Gamma
Explanation: Gamma can be used to destroy different bacteria that causes food poisoning, it can also be used to preserve food and also serve as a prevention against spread of pests. irradiation can serve many purposes. Gamma radiation is used for treatment which include killing of bacteria and deinfestation of agricultural product. It is used to kill microorganisms on a variety of product, and it is ideal for many products. Irradiation is the process of exposing food to a very high source of energy. Gamma irradiation make use of high energy gamma rays that are emitted by radioactive cobalt 60 or Cesium 137.
The correct answer is: Individuals that produce chemical compounds are better protected from herbivores and are able to produce more young than individuals that do not produce the compounds.
Natural selection acts on variations-differences in phenotype that exist among individuals. If a certain trait contribute more to survival and reproduction (individuals with that variant survive more than individuals with other variant), natural selection will favor that trait. In this case, production of chemical compounds is favored over non-producing trait.
Answer:
through a process called cellular respiration
