they form in the bone marrow
a red blood cell lives for approximately 120 days.
Answer;
The similarity between gills and lungs is that both are sites for gaseous exchange in living organisms.
Explanation;
Gills is a site for gaseous exchange in fishes amphibians at some stage in life; while the lungs is a site of gaseous exchange in mammals and other organisms such as reptiles.
They both serve to bring in oxygen in the living things body and the eliminate carbon dioxide from the body; process of gaseous exchange.
However, they differ in a number of ways; for example, lungs are internal while gills are external , lungs are developed to breath in oxygen from the air, while gills are developed to get oxygen from water.
The theory was that physical changes in organisms during their lifetime such as greater development of an organ or part through increased use could be transmitted to their offspring.
Answer:
Rainfall and temperature can affect the rate in which rocks weather. High temperatures and greater rainfall increase the rate of chemical weathering. ... Rocks in tropical regions exposed to abundant rainfall and hot temperatures weather much faster than similar rocks residing in cold, dry regions.
Answer:
Genes that are relatively close to one another on a chromosome will move with one another during the process of fertilization and meiosis. Thus, there will be a lined inheritance for these genes. On the other hand, genes that are found on different chromosomes will have independent inheritances because every pair of the homologous chromosomes will be positioned differently when the
y are arranged at the middle of the cell during the first meiotic division.
