What is the main difference bwtween prokaryotic and eukaryotic cells​
Ymorist [56]

Prokaryotic Cells = do not have a nucleus; generally smaller and simpler that Eukaryotic cells.

-Smaller

-does NOT have a Nucleus

-translates to ‘no Nucleus’ OR  ‘no true Nucleus’

-simpler

-they don't have all of their genetic material bound in a nucleus, which is why they are simpler forms of life.

-Prokaryotic cells do have genetic information but it is just stored differently

Ex: Bacteria and Single-Celled organisms

Eukaryotic Cells = Contains a Nucleus and are usually larger and more complex than a Prokaryotic cell

-Bigger

-DOES have a Nucleus

-More Complex

-Specialized to do certain things

Ex: All the Cells in a Human’s body. Skin cells, Red Blood cells

As evidenced in the graph, the national average CO concentrations have decreased substantially over the years. All BUT ONE tacti
Gekata [30.6K]

Answer:

Explanation:

Carbon monoxide (CO) is a colourless, non-irritant, odourless and tasteless toxic gas. It is produced by the incomplete combustion of carbonaceous fuels such as wood, petrol, coal, natural gas and kerosene. Its molecular weight is 28.01 g/mol, melting point −205.1 °C, boiling point (at 760 mmHg) −191.5 °C (−312.7 °F), density 1.250 kg/m3 at 0 °C and 1 atm and 1.145 kg/m3 at 25 °C and 1 atm, and relative density (air = 1) 0.967 (1,2). Its solubility in water at 1 atm is 3.54 ml/100 ml at 0 °C, 2.14 ml/100 ml at 25 °C and 1.83 ml/100 ml at 37 °C.

The molecular weight of carbon monoxide is similar to that of air (28.01 vs approximately 29). It mixes freely with air in any proportion and moves with air via bulk transport. It is combustible, may serve as a fuel source and can form explosive mixtures with air. It reacts vigorously with oxygen, acetylene, chlorine, fluorine and nitrous oxide. Carbon monoxide is not detectable by humans either by sight, taste or smell. It is only slightly soluble in water, blood serum and plasma; in the human body, it reacts with haemoglobin to form carboxyhemoglobin (COHb).

The relationship of carbon monoxide exposure and the COHb concentration in blood can be modelled using the differential Coburn-Forster-Kane equation (3), which provides a good approximation to the COHb level at a steady level of inhaled exogenous carbon monoxide.

Conversion factors

At 760 mmHg and 20 °C, 1ppm = 1.165 mg/m3 and 1 mg/m3 = 0.858 ppm; at 25 °C, 1 ppm = 1.145 mg/m3 and 1 mg/m3 = 0.873 ppm.

It might knock the old theory away completely because all of the new knowledge doesn't support the theory or it could change it because some of the new information supports the old stuff.

What is the general shape of the epithelial cells that are nearest the lumen in an empty urinary bladder?
OverLord2011 [107]

The general shape of the epithelial cells that are nearest to the lumen in an empty urinary bladder is in multiple cell layers which are considered to be a stratified tissue and the cells in it are shaped in terms of the organ’s distention. This type of epithelial cell is the transitional epithelium.

What do the parietal cell produce? What type of environment is created?
Kobotan [32]

Parietal cells produce gastric acid (hydrochloric acid) in response to histamine (via H2 receptors), acetylcholine (M3 receptors) and gastrin (gastrin receptors). Parietal cells contain an extensive secretory network (called canaliculi) from which the HCl is secreted by active transport into the stomach.
