Streptococcus is a genus of spheroidal bacteria that belongs to the Streptococcaceae family.
The bacteria's distinctive clustering in chains that resemble a string of beads is referred to as streptococcus ("twisted berry"). Microbiologically, streptococci are classified as gram-positive and nonmotile. Cocci :Streptococcus is a genus of gram-positive coccus (plural cocci) or spherical bacteria belonging to the Streptococcaceae family, which is part of the Lactobacillales (lactic acid bacteria) order in the Firmicutes phylum.
Gram-positive cocci are a diverse collection of bacteria that have a similar shape. Sarcina cells, for example, are grouped in cubical pockets. Streptococcus spp. resemble a string of pearls. Staphylococcus species do not divide on a regular plane.Bacilli :Streptococcus bacteria subdivide into Strep. pyogenes (Group A), Strep. agalactiae (Group B), enterococci (Group D), Strep viridans, and Strep pneumonia. Gram-positive bacilli (rods) subdivide according to their ability to produce spores.
If complete hemolysis of the blood cells is observed, the streptococci are classified as beta'hemolytic. M protein is considered the most important virulence component of S. pyogenes. Antibodies that react with M protein are produced in response to infection. A prospective antistreptococcus vaccination based on the M protein or a derivative of it is being studied.Tetrads :The tetrad occurs in a subgroup of the cocci where the bacterium divides in two planes to form a square of four bacteria called a tetrad. Some examples of tetrad-forming bacteria are the lactic acid bacilli, Aerococcus, a urinary tract pathogen and Pediococcus and Tetragenococcus, both of which ferment foods.
Tetrads are groups of four cocci that are positioned in the same plane (e.g. Micrococcus sp.). Sarcina is a bacterial genus that consists of eight cocci arranged in a cuboidal pattern (e.g. Sarcina ventriculi).Sarcinae :Sarcina is a Gram-positive cocci bacterium genus belonging to the Clostridiaceae family. After the cuboidal (2x2x2) cellular affiliations they create during division along three planes, the genus gets its name from the Latin word "sarcina," which means "pack or bundle."
Diplococci are pairs of cocci; streptococci are rows or chains of such cells; staphylococci are grapelike clusters of cells; sarcinae are packets of eight or more cells; and tetrads are groups of four cells in a square layout. Variations in the reproductive mechanism of bacteria result in these distinctive groups.Strepto :a combining term that means "twisted" and is used to make composite words: streptococcus
Streptococcus- a spherical or oval bacteria of the genus Streptococcus that occurs in pairs or chains and is harmful for humans, causing scarlet fever, tonsillitis, and other diseases.Fastidious :Streptococcus is a genus of gram-positive cocci that are organized in chains. These are fastidious bacteria that need blood or serum added to their culture medium. They are non-motile and do not produce spores. Most are facultative anaerobes, which means they can grow on enriched media.
Streptococcus pyogenes - it's a nutrient-concious bacteria that ferments glucose to make lactic acid and has stringent growth needs. This section explains the growth and maintenance of S. pyogenes to help in the research of this organism.Can Grow In Salt :On the basis of their salt tolerance, the salt tolerance test is used to identify enterococcal group D Streptococcus. Several bacteria, notably viridians streptococci, have been classified based on their capacity to thrive in the presence of a varying quantity of sodium chloride (NaCl).
The non-beta hemolytic streptococci (viridans, and non-enterococcal group D) do not grow in 6.5% NaCl broth; but some of the beta-hemolytic strains may grow in the broth.Can Grow In Acid :Some streptococci can create acids, grow in acidic surroundings (acidophilia), make acids at low pH levels (aciduric capability), and synthesis intracellular and external polysaccharides.
Dental caries is associated mainly with acid production at pH values below 5 by nongrowing bacteria in dental plaque. Oral streptococci cannot grow at pH above about 5, although they can lower the pH of suspensions or biofilms to values of 4 or lower.Normal Flora of The Skin:Bacteria make up the vast bulk of typical flora. Skin and nasal membranes are typically infected with Staphylococcus epidermidis.
Staphylococcus epidermidis is a Gram-positive bacterium that belongs to the Staphylococcus genus, which has around 40 species. It is found in marine sponges and is part of the normal human flora, most usually the skin flora and less commonly the mucosal flora.Sources: ( https://www.cdc.gov/ )

What Is Chemogeny ( Chemical Evolution ) ? And Explain The Steps Of Chemogeny [Both Answer In Simple Word/ Simple Answer Which Is Easy To Concept Or Read]
Answer:
Chemogeny may be a theory of chemical evolution that depends on the chemical reactions and formation of drugs on the bases of chemical reactions. This theory says that “Life occurs as a results of evolution of inorganic matter”.
In the 1920's Scientists Oparin and Haldane, developed this hypothesis of the chemical origin of life from the primitive atmosphere of the world having matter like methane, ammonia and water. there have been very low concentrations of oxygen thanks to the presence of high temperatures like 5000-60000C. So, these conditions weren't suitable for the free existence of organic compounds, so reactions started happening .
Under conditions like high sunlight and warmth , inorganic matter gets converted to inorganic compounds. And this might end in the storage of organic compounds, which gets more and more concentrated with the passage of many years.
These compounds interact with one another and end in “life”.
So, chemogeny is that the process of chemical evolution of earth and formation of life from pre-existing matter with the assistance of chemical reactions.

Hopefully I was able to help you with the concept. Good luck!
4. How does the life of a sperm cell vary among the mosses, ferns, gymnosperms and angiosperms?
Answer:
They evolved on land to begin with from earlier now extinct groups groups so there was no need to adapt to life on land, other than to adapt to different terrestrial environmental pressures. Land can be everything from next to a river to a hot desert to rocks to Antarctica, and plants grow in all those places.
As well, there are thousands of species that are floating aquatics or submerged aquatics, including many ferns, and even some gymnosperms grow as marginals, and many species of angiosperms, mosses, ferns, and even some gmnosperms grow as epiphytes, or as parasites, or other ways.

Explanation:
When an egg and a sperm cell unite, the resulting fertilized egg cell receives DNA from both parents.
Distinguish between dimorphic, polymorphic, and continuously variable traits.
Dimorphic, polymorphic, and continuously variable traits are distinguished as follows:
Dimorphism is the condition of those species of animals or plants that exhibit two anatomical aspects or two different forms.When talking about polymorphisms in genetics, reference is made to the different variations that may exist on the DNA of the same gene.Continuously variable traits are those that show a continuous distribution of phenotypes.Therefore, we can conclude that dimorphism is a polymorphism with only two forms, the polymorphism is any stable change of the DNA fixed in the population and in continuously variable traits the phenotypes show a continuous series and cannot be easily grouped.

An area that has been sampled to have a large population of organisms. Does this represent high biodiversity? Why or why not?
An area that has been sampled to have a large population of organisms is
regarded as having a high biodiversity.
Biodiversity is defined as the condition in which areas have a high amount
of plant and animal species present there. Any place with a large population
of organisms is said to have a high biodiversity while places with low
population of organisms have low biodiversity.
The stated facts therefore makes an area that has been sampled to have a
large population of organisms represents high biodiversity.

Answer:
I suppose the answer is C
Each layer of a soil profile best describes a soil horizon.
What is a soil horizon?A soil horizon is a layer of soil within a soil profile. A soil profile is a vertical section through the soil, showing the different layers, or horizons, of soil that make up the soil. Soil horizons are typically classified based on their physical, chemical, and biological properties, and they can vary in thickness and composition depending on factors such as climate, vegetation, and the underlying geology.
Some common soil horizons include the surface horizon, the subsoil, and the parent material.
