When you get an infection, the bacteria are swimming around your big cells like little rowboats next to a large ship. Bacteria are a lot simpler than human cells. A bacterium consists of an outer wrapper called the cell membrane, and inside the membrane is a watery fluid called the ...
How many chromosomes does a human gamete (egg or sperm cell) have? A) 46. B) 23. C) 2. D) 13. E) 92. If humans have 46 chromosomes in each of their body cells, how many chromosomes would you expect to find in a sperm cell? A sperm has 16 chromosomes. How many chromo...
Teratozoospermia can be diagnosed through a basic semen analysis or sperm test, along with a staining method that allows sperms to be visible under the microscope.

instead of there being one large deposit of fossils corresponding to the Cambrian explosion, there were actually five distinct sedimentary levels formed by variations in sea level. This suggests that the longstanding narrative of a Cambrian "explosion" is inaccurate, and that it was really a series...
Why is cell division important even after development is complete? Why are large cells not as efficient as small cells? Explain the factors that affect bone growth, both dietary (vitamin, minerals) and hormonal. What happens in a cell during the S portion of interphase?
During fertilization, a sperm cell will fuse with an egg cell that, in a successful pregnancy, will then implant in the uterus. The fertilized egg will then mature into what's called a blastocyst, then an embryo and, finally, a fetus. A placenta forms to support this process. The ...
