Answer:
b is the correct answer i guess
Red blood cells, also known as RBCs, red cells, red blood corpuscles, haematids, erythroid cells or erythrocytes, are the most common type of blood cell and the vertebrate's principal means of delivering oxygen to the body tissues—via blood flow through the circulatory system. RBCs take up oxygen in the lungs, or gills of fish, and release it into tissues while squeezing through the body's capillaries.
this is about red blood cells but what are you asking
They have longer periods of revolution.
❤️Hello!❤️ In my opinion, i'm against GMO's. First of all you need to understand what GMO stands for, GMO means (Genetically Modified Organisms) and does that REALLY sound appealing to eat (Be honest). So now we have that covered i'm going to tell you some reasons why YOU should avoid Genetically Modified Organisms (GMO's). First of all GMO's are unhealthy, according to the American Academy of Environmental Medicine. They cite animal studies showing organ damage, gastrointestinal and immune system disorders, accelerated aging, and infertility. Second of all, GMO's contaminate forever. GMO's cross pollinate and their seeds can travel. It is impossible to fully clean up our contaminated gene pool. Self propagating GMO pollution will outlast the effects of global warming and nuclear waste. The impact is huge, threatening the health of future generations. Third of all, GMO's increase herbicide use, most GMO crops are engineered to be “Herbicide tolerant”―they deadly weed killer. Monsanto, for example, sells Roundup Ready crops, designed to survive applications of their Roundup herbicide. Between 1996 and 2008, US farmers sprayed an extra 383 million pounds of herbicide on GMO's. Overuse of Roundup results in “superweeds,” resistant to the herbicide. This is causing farmers to use even more toxic herbicides every year. ♒️ Hope this helps!♒️ ↪️ Autumn ↩️
