As you know, sperm cells look a bit like tadpoles with long tails, orflagella, which they whip in order to swim to their destination and fertilize an egg cell. The sperm tail is made of tubulin and is an example of a microtubule filament used for cell locomotion. Another well-known moti...
thanx reply mentor february 20, 2020 at 5:32 pm mitochondrial donation is an in-vitro fertilization technique used to treat mitochondrial diseases. the processes involve the extraction of a nuclear dna from a patient with faulty mitochondria and inserting it into the egg of a healthy donor. ...
This function is important for the reproduction of higher organisms, including humans, because embryos develop from a fertilized egg. The egg cell from the mother is large and contains a lot of mitochondria in its cytosol while the fertilizing sperm cell from the father has hardly any. As a r...

In a structure in which racks back-to-back with each other are placed on a floor, a bottom of at least one of the racks is pressed against the floor by a connecting bar crossing the bottom. In a structure in which a cover is mounted on a rack, a cover has a first shaft movable ...
What is the role of the zona pellucida? The zona pellucida has four primary roles: 1. It allows only same-species sperm to reach the egg. 2. It allows only one sperm to reach the egg. 3. It protects the growing cluster of cells after fertilization. and 4. The blastocysts (growing cl...
but what I want to discuss now are shells. These are structures that have thin curved surfaces that translate loads to their supports by tension, compression and shear only: The buildings most emulating the egg. In this field all roads do initially lead to Rome (the dome of the Pantheon, ...
In the tubes, an egg cell may become fertilized. If it does, it travels through the uterine tube to the body of the uterus. It then incorporates into the uterine wall and starts growing, from embryo to fetus. In case an egg cell is not fertilized, the uterus notices that and starts ...
