What is binomial nomenclature and what two categories are used in a binomen?
Binomial nomenclature is a system of using two names to identify a species, which are the genus and the species names. The genus name starts with a capital letter, but the species name is written in all lower case letters. The genus and species names should either be italicized (in print) or underlined (when handwritten). No two species on earth can have the same species name, but they can have the same genus name. Examples include the gray wolf (Canis lupus), the coyote (Canis latrans), and the domestic dog (Canus lupus familiaris). The gray wolf, the coyote, and domestic dog are in the same genera (plural for genus), but in different, unique species or subspecies (the domestic dog).
What is the difference of a homozygote and a heterozygote?
A homozygote carries two identical alleles for a particular gene, while a heterozygote carries two different alleles for the same gene. Homozygotes produce only one type of gamete, while heterozygotes can produce two different types of gametes.
What makes up a scientific name?
New species are scientifically named in a process that can take a long time. Each species is given a species name, a genera, a family and an order. As of 2014, more than 1.9 million species have been discovered and named in this way.
How many repeats of the Calvin Cycle are required to produce one glucose molecule?
Two repeats of the Calvin Cycle are required to produce one glucose molecule.
Sporulation usually occurs in response to what?
Sporulation is the process for bacteria that results in the production of an endospore. When bacteria are in a hostile environment, they produces dormant bodies known as endospores. Sporulation enables the bacteria to survive in hostile environments until a more suitable environment is available.
What Two genera that are oxidase positive?
Neisseria, Alcaligenes, Moraxella, and Pseudomonadaceae are genera of oxidase positive microorganisms.
Is ammophilia a type of cactus?
Ammophila is the Latin name of two genera
What two gram positive groups make endospores?
Bacillus and Clostridium are the two main groups of gram-positive bacteria that are capable of forming endospores. Endospores are dormant, resistant structures that allow these bacteria to survive in harsh environments.
What are heterosporous genera?
Heterosporous genera are plant genera that produce two types of spores: microspores (male) and megaspores (female). Examples include Selaginella, Isoetes, and Marsilea in the plant kingdom. This heterospory allows for the development of separate male and female gametophytes, enhancing reproductive success and evolutionary adaptability.
What is a rattlesnake's species?
There are two genera of rattlesnake - crotalus and sistrurus. There are about 36 species between these two genera,
What are the two techniques used to visualize endospores?
The crystal violet method and the Schaeffer-Fulton method
What are the two common techniques used to visualize endospores?
The two common techniques used to visualize endospores are Schaeffer-Fulton method and the Dorner technique. The Schaeffer-Fulton method involves staining the endospores with malachite green and safranin, while the Dorner technique uses fluorescence microscopy to visualize endospores stained with a fluorochrome dye.
What are two genera of elephant?
Elephas and loxodonta
How can you determine the relative age of two cultures of the same organism through endospore staining?
By examining the number and condition of endospores in each culture, you can infer the relative age. Older cultures will have fewer viable endospores, with many showing signs of deterioration or damage. A culture with a higher percentage of intact, healthy endospores is likely younger.
What are the two words that are most often used for the scientific naming of animals?
Genera and species.These are the most specific categories. For Instance: for humans, the Genera and species are Homo sapiens.
What are the two characteristics of endospores?
Endospores are highly resilient, allowing them to withstand extreme conditions such as heat, desiccation, and radiation. They are formed by certain bacteria as a survival mechanism during unfavorable environmental conditions and can remain dormant for long periods until conditions improve for growth. Additionally, endospores have a tough outer layer, composed of proteins and peptidoglycan, that protects them from damage.
Can bears and dogs have babies together?
No. They are two different species, and not even in the same family.
