The primarily use of coal is mostly used for electricity generation, steel production, cement manufacturing, and as liquid fuel. 

Advantages: it helps produce electricity, coal energy is affordable energy source because coal's stable price compared to other fuels sources, coal is easy to burn, coal produces high energy upon combustion, coal energy is inexpensive, coal is abundant, coal energy is a reliable energy source. 

Disadvantages: coal energy produces large amount of carbon dioxide which leads to global warming and climate change, the burning of coal is not environmental friendly because it produces harmful byproducts and gas emission such as sulfur dioxide, carbon dioxide and nitrogen oxide that causes pollution to the environment including acid rain, coal energy is nonrenewable energy source, coal is fast depleting because we dont consume too much of it, coal mining ruins the environment and puts the lives or people especially the coal miners in danger. <span />

Explain how the edges and corridors can strongly influence landscape biodiversity
Dahasolnce [82]

Answer:

The edges or boundaries between the ecosystems and within it are the illustrating characteristics of landscapes. In a landscape, the biodiversity is affected by the composition of the landscape itself. When an area possesses boundaries or edges, which minimize the area of the habitat, it also starts to minimize the number of species, which can associate with the communities.  

The multiplication of edge species can exhibit both negative and positive influences on the biodiversity of a community. On the other hand, corridors refer to the region associated with the populations of wildlife distinguished by human activities like road construction. The prime objective of designing habitat corridors is to enhance biodiversity. The corridors that have been protracted to other habitat patches can reinstate a certain degree of space and at the same time reestablish certain chances for genetic diversity.

If a chromosome in one of your bone cells becomes mutated, you will not pass this mutation onto your children because
Sladkaya [172]
A person will not pass this mutation onto children because somatic cells cannot go through meiosis if a chromosome in one of the bone cells turn out to be mutated.

What are the three types of cell signaling
PIT_PIT [208]

Answer:

there are 4: paracrine signaling, autocrine signaling, endocrine signaling, and synaptic signaling

Explanation:

paracrine:cells that are near one another communicate through the release of chemical messengers 

autocrine: a cell signals to itself, releasing a ligand that binds to receptors on its own surface 

endocrine:When cells need to transmit signals over long distances, they often use the circulatory system as a distribution network for the messages they send. 

synaptic: nerve cells transmit signals. The junction between two nerve cells where signal transmission occurs.

Angiosperms and life on land Many aspects of the angiosperm life cycle make flowering plants particularly well-suited to life on
vova2212 [387]
<h2>Angiosperms </h2>

Explanation:

Angiosperms are the most diverse group of plants, some statements which reflect angiosperm adaptations to life on land:

  • Flowers attract animal pollinators carrying pollen from other plants of the same species
  • Fruits aid in the dispersal of seeds by wind or by animals that carry or eat the fruits
  • In many angiosperms, the male gametophyte contained in a pollen grain can be transported many miles away by wind or animal pollinators
  • Floral parts of the sporophyte protect the reduced female gametophyte from drying out and from UV radiation
  • Seeds protect and nourish plant embryos, and fruits protect the seeds
  • Seeds enable plant embryos to be dispersed long distances from the parent plant via wind or animals
