The correct answer is option C

Crop dusters is the aircraft that involves the spraying the chemical fertilizers, insecticides and herbicide over the crops from by aerial application.

The spraying of those chemicals is done at the intentional sites but sometimes the diffusion of these chemicals reaches the unintentional sites and causes chemical or vapor drift.

It can cause accidental exposure to the animals, plants or human beings and can be harmful for them.

Members of the phylum ____ are considered by many researchers to be the living plants most closely related to vascular plants, b
DIA [1.3K]

Answer: The answer is Anthocerophyta

Explanation: Anthocerophyta are widespread and occur in the temperate & tropical zones. The species of plants in this phylum have horn-shaped sporophytes which are known as "flower horn". As in other bryophytes, the sporophyte of this phylum remains attached to its parent gametophyte throughout its life, but unlike these other plants, the sporophyte continues to grow throughout its life; this happens as a group of cells at the base of the horn divide repeatedly. They also possess stomates, which exchange gases between the plant and the air.

The mitochondrial genome evolution in Anthocerophyta is closer to that of seed plants but not as dynamic.

Which idea associated with relative dating helped inspire Charles Darwin's work on evolution?
mrs_skeptik [129]

Answer: The idea that the earth is extremely ancient.

Explanation:

Charles Darwin was a British naturalist who worked on the organic evolution of living organisms and in his books outlined how present-day organisms evolved from earlier, different species.

Evolution is an extremely slow process. It is difficult to obtain direct evidence of evolution in action. However, scientist including Charles Darwin, have from many fields gathered a great deal of indirect evidence that supports the theory of evolution. This evidence comes from many sources which include the FOSSIL RECORDS.

The history of life on earth is recorded in fossils (remains of organisms preserved mainly in earth's sedimentary rocks). Scientist can determine the age of rocks in which fossils occurs by using RELATIVE DATING. This method give a geological time scale, showing earth's age ( as measured by dating it's rocks), and tracing the history of life on it.

Therefore the idea that the earth is extremely ancient is associated with relative dating which has helped inspire Charles Darwin's work as an evidence on evolution.
