You'll need an iron nail, copper wire, a D-cell battery, paper clips or pins, and masking tape.

wrap the copper wire around the nail downward. then wrap one end of the exposed wire around the positive side of the battery and the other end around the negative side of the battery and use the tape to hold them together. place the nail near the paper clip/pin. you can experiment with different sizes too, but this should work (:

The question is incomplete as it does not have the option which are:

  • Favorable genes from parental generations provide advantageous characteristics to the hybrid species.
  • Hybridization produces offspring traits that allow different species to survive in extreme environments.
  • Inherited traits passed on from parental generations make hybrid species more susceptible to disease.
  • Hybrid species display more adaptation due to their reduced genetic diversity

Answer:

Favorable genes from parental generations provide advantageous characteristics to the hybrid species.

Explanation:

The white cattail is the plants which grow in the wetlands that are they are adapted to grow in the wetlands. The white cattail species in nature is the result of natural hybridization that is mixing of the genes of two different species of the same genus.

The white cattail can when grown in the Midwestern states well adapted to grow in that area and the reason for this could be accounted that the genes from the parental plants provided many advantages to the newly formed hybrid species.

Thus, the selected option is correct.

An important condition for the formation of coal is ________.
Anastasy [175]

Answer:

Incomplete decomposition of organic matter due to a lack of oxygen. (Ans D).

Explanation:

Coal is known as the mostly carbon with containing different amounts of oxygen, nitrogen, sulfur, and hydrogen. Coal is formed when Incomplete decomposition of dead plant matter due to a lack of oxygen occurs. In-plant matter because of the pressure, and heat-generating physical, and chemical changes occur which lead to force out oxygen, and carbon deposits left. so, in this time the plant matters become coal.

Coal is divided into three main types which are based on the percentage of hydrocarbon, oxygen, and carbon occurs in the coal.

1) Anthracite coal.

2) Bituminous coal.

3) Lignite coal.

Name four of the disciplines that contribute to the study of our interactions with the environment.
AnnyKZ [126]

Answer:

Environmental science is an interdisciplinary academic field that integrates physical, biological and information sciences (including ecology, biology, physics, chemistry, plant science, zoology, mineralogy, oceanography, limnology, soil science, geology and physical geography, and atmospheric science) to the study of the environment, and the solution of environmental problems. Environmental science emerged from the fields of natural history and medicine during the Enlightenment.[1] Today it provides an integrated, quantitative, and interdisciplinary approach to the study of environmental systems
