In biology, the strain is a low-level taxonomic rank used in different contexts:
In microbiology, a strain is a part of a bacterial species different from other bacteria of the same species by a minor but identifiable difference. Strains are often created in the laboratory by mutagenesis existing strains or wild-type examples of bacterial species.
In zoology, a strain corresponds to an individual or group of individuals who are at the origin of a line of descendants, sometimes called the holotype, paratypes, etc. A strain is a population of organisms that descends from a single organism or pure isolate culture. Strains of the same species may differ slightly from each other in many respects.
A strain thus consists of a group of organisms of the same species possessing certain differential traits based on their relationship; either they come from the same region, as the same watershed of a river, or they are the fruit of a particular breeding program (exists as a whole interbreeding without introductions from external sources).
B is the correct answer because none of this that you put are testable.
Answer: Yes.
Explanation:
Fermentation is a general term denoting anaerobic degradation of glucose or other organic nutrients in various products to obtain energy in the form of ATP. Fermentation occurs when, after glycolysis, the Krebs cycle is not performed, because the organism does not have it or because this pathway is blocked, such as during hypoxia (lack of oxygen). Fermentation is a process used by bacteria to obtain energy, does not use oxygen and occurs in the cytoplasm of cells, ie an intracellular process, and each step is catalyzed with the help of different enzymes.
Some industries use this process in the production of some products, known to all of us, such as:
1. yogurt is produced by the famous lactic fermentation, where bacteria called lactobacilli to produce lactic acid.
2. bread and beer are produced by alcoholic fermentation, where the fermentation is carried out by fungi (facultative anaerobic), which ultimately produce alcohol;
3. vinegar to that produced by acetic fermentation, which consists of a chemical reaction, where partial oxidation of ethyl alcohol occurs, obtaining acetic acid.
Answer:
A. Taxa are based on Latin, not English.
Explanation:
In the classification of organism, the child choose English as primary language but scientists uses Latin language as a primary language for their taxa.
Swedish scientist Carl Linnaeus, initiated the classification of organism and he choose Latin names for different taxa such as phyla and species because Latin was a universal scholarly language in Europe.
So, till now scientists uses Latin language for the naming of organisms and the child uses English language.
Hence, the correct answer is A. Taxa are based on Latin, not English.
Answer:
See the answer below
Explanation:
Anthers release pollen, which lands on the stigma of another flower of the same species. The pollen grain produces a pollen tube that grows down the style, to the ovary, and into the ovule. The sperm cell fertilizes the egg cell. The ovule develops into the seed, and the ovary becomes the fruit.
<em>During fertilization in plants, the anther which carries pollen releases pollen grains. Once the pollen lands on the stigma of a flower of the same species, it germinates. The pollen grain produces a pollen tube that grows through the style of the stigma down to the ovary and into the ovule. One of the sperm cells fuses with the egg cell of the ovule to form the zygote while the other sperm cell fuses with the polar nuclei to form the endosperm in a process known as double fertilization. After fertilization, the fertilized ovule becomes the seed and the ovary becomes the fruit. </em>
