Sperm receptor is also known
as zona pellucida sperm –binding protein 3 (ZP-3). It is a ZP module protein in human
that encode by the ZP3 gene. Thus, ZP3 is the receptor that is found in the
zona pellucida that binds the sperm at the <span>beginning</span><span> of fertilization.</span>
Answer:
<em>The correct option is D. It is carbon dioxide released by respiration.</em>
Explanation:
The process by which ATP is abundantly formed in organisms is termed as cellular respiration. Cellular respiration can be described as a process in which carbon dioxide and water are produced from glucose and oxygen. ATP molecules are synthesized by this process which are used for cellular activities.
Hence, the substance X in the investigation shows carbon dioxide which was produced when the yeast cells began to respire. Yeast cells can respire either in the presence of oxygen or without oxygen.
Answer:
The process that produces fuel for motor vehicles from living plant products is alcoholic fermentation.
Nanotechnology is in fact effective at helping clean up PCB’s or polychlorinated biphenyls and
similar compounds with the use of nanoparticles. Aside from this, it also <span>protect workers exposed to pesticides occupationally by regulating
pesticide use. </span>
<span>In addition, it reduces
the concentration of pesticides found in watersheds. Therefore, the answer is
A. only promote pesticide use in rural environment. </span>
Translation occurs in the nucleus to produce a pre-mRNA molecule. The pre-mRNA is the processed into the mature mRNA which exists the nucleus and is translated into the cytoplasm.
So, the answer is B) NUCLEUS
