A ribosome itself looks like a little hamburger bun. It's made of two subunits: a big one (the top bun) and a small one (the bottom bun). Eukaryotic ribosomes are found floating freely in the cytoplasm or attached to the rough endoplasmic reticulum (RER or rough ER for short).
Bottom line: Nuclear heterochromatin and the nucleolus (containing ribosomes and RNA) stain blue/purple and the cytoplasm of cells rich in ribonucleoprotein also stains intensely with hematoxylin. Collagen is found extracellularly and not within the cell and also stains pink or orange with eosin.
Ribosomes are special because they are found in both prokaryotes and eukaryotes. While a structure such as a nucleus is only found in eukaryotes, every cell needs ribosomes to manufacture proteins.
Ribosomes are very important cellular organelles that are tasked with synthesizing proteins. Eukaryotic ribosomes are called 80S ribosomes while prokaryotes such as bacteria have a smaller version called 70S ribosomes.
purple-blackBasophils are the least numerous of the granulocytes and account for less than 1 percent of all white blood cells occurring in the human body. Their large granules stain purple-black in colour and almost completely obscure the underlying double-lobed nucleus.
Eosin is an acidic dye: it is negatively charged (general formula for acidic dyes is: Na+dye-). It stains basic (or acidophilic) structures red or pink. This is also sometimes termed 'eosinophilic'.
Ribosomes are composed of two subunits with densities of 50S and 30S ("S" refers to a unit of density called the Svedberg unit). The 30S subunit contains 16S rRNA and 21 proteins, the 50S subunit contains 5S and 23S rRNA and 31 proteins. Ribosomal subunits are composed of ribosomal RNA (rRNA) and proteins.
Since both the sub-units of 70S ribosome take 30 × 10^-13 and 50 × 10^-13 seconds respectively, therefore a 70S ribosomes has 30S and 50S sub-units. The entire ribosome takes 70 ×10^-13 seconds to sediment, hence 70S. The explanation is similar for eukaryotic ribosomes.
While viruses do not have their own ribosomes—they hijack the ribosomes of the human cell to make more virus—it may be possible to exploit the unique methods by which viruses take over the human ribosomes to create novel anti-viral drugs.
Bacteria and archaebacteria have smaller ribosomes, termed 70S ribosomes, which are composed of a small 30S subunit and large 50S subunit. The "S" stands for svedbergs, a unit used to measure how fast molecules move in a centrifuge.

Basophils are a type of white blood cell. Basophils are the least common type of granulocyte, representing about 0.5% to 1% of circulating white blood cells. The name comes from the fact that these leukocytes are basophilic, i.e., they are susceptible to staining by basic dyes, as shown in the picture.
-pinkThe granules in a neutrophil are small, numerous, and are stained a light-pink to bluish-purple, “neutral” color. The cytoplasm of a neutrophil is light pink. When a person is fighting infection, the granules may be dark colored. This is called toxic granulation.
"Basophils" are cells that "love" the blue, and usually show up deep blue under standard staining techniques (H&E).

Without a host cell, viruses cannot carry out their life-sustaining functions or reproduce. They cannot synthesize proteins, because they lack ribosomes and must use the ribosomes of their host cells to translate viral messenger RNA into viral proteins.
A virus is a small collection of genetic code, either DNA or RNA, surrounded by a protein coat. A virus cannot replicate alone. Viruses must infect cells and use components of the host cell to make copies of themselves.
Ribosome Structure and Composition. Ribosomes are composed of ribosomal RNA (rRNA) and protein. The 30S subunit contains 16S rRNA and 21 proteins, the 50S subunit contains 5S and 23S rRNA and 31 proteins. The two subunits combine during protein synthesis to form a complete 70S ribosome about 25nm in diameter.
Heparin is produced by basophils and mast cells in all mammals.
Basophils: Normal And Abnormal Ranges This count can be as low as 0.5%. As an absolute count, an adult human should have 0 to 300 basophils per microliter of blood. There usually are no symptoms for an abnormal range of basophils.

The intense pink staining in the eosinophils is the reason why these cells were named "eosinophils", meaning "eosin loving". In the high-magnification H&E staining of blood eosinophils above (right panel), the bright pink marks the mediator- and protein-stuffed granules that break open when the eosinophil is activated.
Basophils play a part in "immune surveillance". This means they have the ability to help detect and destroy some early cancer cells. Another important function of basophils is that they release the histamine in their granules during an allergic reaction or asthma attack.
System. debug() lets us print any values in our Apex code for debugging purposes. This can be very useful for debugging any errors you encounter. We can access the debug logs from the developer console, there are also some IDE's that support debug logs in Salesforce.

In its basic form, curbside pickup is placing an order online – via web or mobile and then driving to the store to pick it up. Sometimes this means parking, going inside the store, and waiting in a “mobile order” or “online order” queue.
