Here is the full statement: A scientist begin working by trying to explain a natural occurrence that is OBSERVABLE.
Scientific method refers to the techniques that scientists used to carry out scientific investigations and it is made up of series of steps. The first step is observation. A scientist normally begin the process of scientific investigation by observing a phenomenon that occur naturally. The observation will lead to questions, which need to be answered and which eventually lead to conduction of experiments.
The slow rate at which diffusion occurs over large distances.
Answer:
No
2. Yes
Explanation:
This is because DNA undergo transcription to produce RNA and RNA undergo translation to produce protein. Translation is the process where mRNA molecule is used as a template to produce protein.
RNA undergo mutation more than DNA and this is because the enzymes found in RNA viruses and participate in copying viral genomes is why it occur so. These enzymes does not have the abilities to recognize DNA damage that enzymes in most organisms have.
Answer:
A vascular plant is any one of a number of plants with specialized vascular tissue. The two types of vascular tissue, xylem and phloem, are responsible for moving water, minerals, and the products of photosynthesis throughout the plant. As opposed to a non-vascular plant, a vascular plant can grow much larger.
Explanation:
Taxonomy- the classification of something, especially organisms.
Classify- arrange (a group of people or things) in classes or categories according to shared qualities or characteristics.
Binomial nomenclature- the scientific way to name living things with a two part generic (genus) and specific (species) name.
Kingdom- a country, state, or territory ruled by a king or queen.
Species- a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding. The species is the principal natural taxonomic unit, ranking below a genus and denoted by a Latin binomial, e.g. Homo sapiens.
Prokaryote- a microscopic single-celled organism which has neither a distinct nucleus with a membrane nor other specialized organelles, including the bacteria and cyanobacteria.
Eukaryote- an organism consisting of a cell or cells in which the genetic material is DNA in the form of chromosomes contained within a distinct nucleus. Eukaryotes include all living organisms other than the eubacteria and archaea.
Heterotroph- an organism deriving its nutritional requirements from complex organic substances.
Autotroph- an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.
Unicellular- having or consisting of a single cell.
Multicellular- composed of several or many cells.
