Most of the worlds fossil fuels are made up of Coal.
Prokaryotes are single celled organism that lacks a membrane bound nucleus, mitochondria, or any other membrane bound organelle. Examples of prokaryotes include all single-celled organisms, most of which are bacteria. The principle ecological role of prokaryotes is to break down organic matter.
The number of predators and preys change from time to time following
cycles. Whenever there is fewer prey, predators start dying because they
have not enough to eat; however, that provokes the population of prey
to be increased while there are fewer predators. So if suddenly the
number of prey gets bigger, regardless of the number of predators, the
cycles get disturbed by this sudden occurrence. The predators will get
more to hunt, therefore getting more violent.
The RNA synthesis or ADN transcription occurs in the nucleus and requires:
- DNA strand to act as a template.
- Enzymes, specially the RNA-polymerase.
- Ribonucleotides of Adenine, Guanine, Cytosine and Uracil.
This consist of three maturation of the 3'-->5' direction while the sense of RNA synthesis is 5'-->3'.
This is fulfilled because the enzyme selects the ribonucleotide whose base is complementary to the DNA chain that acts as a template, and binds it by means of a nucleotide bond, releasing a phosphate group.
Answer:
A. Reduction in soil mass proved that plants get their food from the soil.
Explanation:
Plant take their food from the soil because in soil roots are present which absorb nutrients from the surrounding environment. The nutrients present in the soil comes from the decomposition of dead bodies of plants and animals and sometimes it is provided by the farmers in the form of fertilizers. The plant food contains nitrogen, phosphorus and potassium which is required in large amount for the better growth and development of the plant.
