The strength will vary depending on the type of concrete, the base, and the presence or absence of steel or fiberglass reinforcing.
No single person invented underwear. Clothing styles and fashions, including the presence or absence of underwear, have varied widely throughout mankind's history.
1. (1) Produced by an abnormality in, or a mutation of the genetic code in a single gene; (2) Caused by several abnormal genes (Producing so-called polygenic diseases); or (3) Caused by the abnormal presence or absence of an entire chromosome or by alteration in the structure of chromosomes.

Absence of a nucleous
The presence or absence of a nucleus is the major characteristic that classifies a cell as either prokaryotic (lacking a nucleus) or eukaryotic (containing a nucleus). Eukaryotic cells also typically have membrane-bound organelles, while prokaryotic cells do not.
The defining characteristic of prokaryotic cells that sets them apart from eukaryotic cells is the absence of a distinct nucleus.
Cells can be classified based on different criteria, including their structure, function, and presence or absence of a nucleus. Cells can also be classified as prokaryotic or eukaryotic based on the presence or absence of a membrane-bound nucleus. Additionally, cells can be categorized based on whether they are plant or animal cells, based on their specific characteristics and organelles.
Prokaryotic cells can be aerobic (requiring oxygen) or anaerobic (not requiring oxygen), while eukaryotic cells typically require oxygen for aerobic respiration. However, some eukaryotic cells can also perform anaerobic respiration in the absence of oxygen.
Eukaryotic cells have a well-defined cytoskeleton composed of microtubules, actin filaments, and intermediate filaments that aid in maintaining cell shape, support organelles, and allow for cell movement. Prokaryotic cells lack a true cytoskeleton, which can impact their structural integrity, shape, and ability to carry out complex movements compared to eukaryotic cells.
prokaryotic:-1 True nucleus not present. 2 membrane bound organelles are lacking. 3 size- 1-10mm 4 single chromosomes. 5 nucleus absence. Eukaryotic:- 1True nucleus present. 2 organelles are membrane bounded. 3 size- 5-100mm 4 more than 1 chromosomes. 5 nucleus present.
Two traits used to classify organisms into each domain are cell type (prokaryotic or eukaryotic) and cellular structure (presence or absence of a nucleus). These traits help differentiate between the three domains of life: Archaea, Bacteria, and Eukarya.
eukaryote cellA single-celled or multicellular organism whose cells contain a distinct membrane-bound nucleus.prokaryote cellAn organism of the kingdom Prokaryotae, constituting the bacteria and cyanobacteria, characterized by the absence of a nuclear membrane and by DNA that is not organized into chromosomes.
Well honey, the best criteria to use when classifying cells as eukaryotes or prokaryotes is their cellular structure. Eukaryotic cells have a nucleus and membrane-bound organelles, while prokaryotic cells don't have a nucleus and their DNA floats around in the cytoplasm like a free spirit. It's as simple as that, darling.
Most Eukaryotic cell need oxygen to live .
No. Prokaryotic cells do not have a nucleus. In fact, the classification of an organism as prokaryotic is based on the absence of a nucleus.
