I believe, for the artery, they have, an open, circular lumen an a thick media
Veins on the other hand, have somewhat collapsed lumen and a thinner media. Arteries are blood vessels that carry blood out of the heart to other parts of the body, all arteries carry oxygenated blood except the pulmonary artery which carries deoxygenated blood from the heart to the lungs. Veins carry blood from other body parts to the heart, all veins carry deoxygenated blood except the pulmonary vein which caries oxygenated blood from the lungs to the heart.
Answer:
16 cells
Explanation:
According to the given information, the generation time of the bacterial cell is 15 minutes. This means that the bacterial cell would have a total of 60/15= four divisions (1 hour= 60 minutes) in one hour. A division in a single bacterial cell produces two new bacterial cells. If both the newly formed bacterial cells enter the cell division, a total of four cells will be formed. Likewise, if all the newly formed bacterial cells enter the process of cell division, a total of 2^4= 16 cells will be formed by the end of four consecutive cell divisions.
Answer:
round and in chains
Explanation:
<em>Streptococcus agalactiae </em>is a gram positive bacteria. It is facultative anaerobe and forms a part of microbiota in gastro intestinal and urinary tract of healthy humans. It can cause infections in immuno compromised beings.Its genus name describes its morphology. Coccus are round spherical shaped bacteria. Strepto means that the bacteria are present in chain form. Hence this bacteria is spherical and arranged in chains.
There are several other types of bacterial morphology. For example: Staphylococcus means that the bacteria is again spherical but this time arranged in groups. Diplococcus means that the spherical bacteria is arranged in a pair. Similarly, bacillus is used to describe a rod shaped bacteria.
Multiple alleles: three or more alleles for a specific gene
polygenic traits: a trait controlled by a group of nonallelic genes
