4.4. How far does a human sperm cell travel to fertilize an egg? 4.5. How fast can a sperm travel? 4.6. Why does the human sperm cell have lots of mitochondria? 4.7. What is the function of the head of the sperm? 4.8. What is the probability that a human sperm cell carries an ...
A Sertoli cell (a kind of sustentacular cell) is a "nurse" cell of the testicles that is part of a seminiferous tubule and helps in the process of spermatogenesis, the production of sperm. It is activated byfollicle-stimulating hormone (FSH)secreted by the adenohypophysis, and has FSH rece...
What is the function of epithelial tissue in the lungs? What organ transports mature sperm cells to the urethra? Where is squamous epithelial tissue found in the body? Which types of cell junctions are found in epithelial tissues? What is the difference ...
Once inside of the fallopian tube, an egg cell has about 48 hours to live. If it is not fertilized by a sperm within this time, it will die. The follicle that released the egg is now called a corpus luteum, and it will secrete a hormone called progesterone for about two weeks after ...
What is the function of spongocoel in sponges? The spongocoel is lined by a variety of cell types, each having a unique function: porocytes – line the pores of the sponge and are the structure through which water is taken into the organism. choanocytes –exhibit flagella that create ...
How the sperm migrate to the egg and become able to fertilize the egg? What is meant by the term "trisomy?" Explain the potential outcomes of trisomies. What is trisomy 21? Explain the stages of oogenesis. What are the major components of a sperm cell and what roles do they have in ...

The main functions of DNA in a human cell are to store and replicate data so that the cell can reproduce. Damage to the DNA or...
But DNA is not the direct template for protein production. To make a protein, the cell makes a copy of the gene, using not DNA but ribonucleic acid, orRNA. RNA shares a similar structure to DNA, except it contains only one strand, rather than two — so it looks like just one half ...
