Only 200 out of 2 000, 000 sperm cells reach the ovum. And only one (in exception to very rare cases of two) sperm cells actually participate in the process of fertilization. In comparison, an average female only produces 400 of egg cells during their lifetime, but the eggs cells are significantly larger than sperm cells.

Explanation:
Edit
The upper mantle of Earth is a very thick layer of rock inside the planet, which begins just beneath the crust (at about 10 km (6.2 mi) under the oceans and about 35 km (22 mi) under the continents) and ends at the top of the lower mantle at 670 km (420 mi). Temperatures range from approximately 200 °C (392 °F) at the upper boundary with the crust to approximately 900 °C (1,650 °F) at the boundary with the lower mantle. Upper mantle material which has come up onto the surface is made up of about 55% olivine, 35% pyroxene and 5 to 10% of calcium oxide and aluminum oxide minerals such as plagioclase, spinel, or garnet, depending upon depth.

Protein-protein interactions within the CARMA1-BCL10-MALT1 complex:
- The T-cell receptor and B-cell receptor-dependent NF-B induction and lymphocyte activation are mediated by the CBM complex, which is made up of the proteins CARMA1, BCL10, and MALT1.
- Each of the proto-oncoproteins CARMA1, BCL10, and MALT1 is a somatic gain-of-function mutation or chromosomal translocation, and dysregulation of CBM signaling is a characteristic of numerous lymphoid malignancies, including Activated B-cell Diffuse Large B-cell Lymphoma.
- Moreover, a number of immunological dysregulation diseases have been linked to both gain- and loss-of-function germline mutations in CBM complex proteins.
- Over the past ten years, careful examination of the interactions of CBM components has yielded a wealth of detailed structural knowledge.
- Here, we discuss important discoveries about the molecular nature of these protein-protein interactions that have helped the research develop a detailed understanding of how these proteins come together to form high-order filamentous CBM complexes.
- Approaches to therapeutic suppression of the CBM complex have thus far centered on obstructing MALT1 protease activity in order to treat lymphoid malignancy and/or autoimmunity.
- The structural effects of MALT1 protease inhibitors on significant protein-protein interactions are also reviewed in detail.
