Answer:
Cell surface receptors (membrane receptors, transmembrane receptors) are receptors that are embedded in the plasma membrane of cells. They act in cell signaling by receiving (binding to) extracellular molecules. They are specialized integral membrane proteins that allow communication between the cell and the extracellular space.
Explanation:
Answer:
The correct answer will be option- synaptonemal complex.
Explanation:
The tetrad arrangement of the genetic material in an organism is mediated by a highly conserved structure known as the synaptonemal complex. The synaptonemal complex is formed during the prophase I of the meiosis I which attaches the chromatin of the homologous chromosomes.
The synaptonemal complex is a proteinaceous structure which is formed by the two lateral ladders like elements with a central portion composed of the central element. The chromatin gets attached to the lateral elements while the central a portion bridge space between the two ladders thus help in the formation of the tetrad.
Thus, option- synaptonemal complex is the correct answer.
All organisms reproduce either sexually or asexually is the correct contrast to the mistaken idea of spontaneous generation
C . all the organisms reproduce either sexually or asexually
<u>Explanation:</u>
The organism could not arise only through the sexually and the asexual reproduction but it is also reproduced through the process of spontaneous generation.
The essential character is offspring is while mother supply is the only solid substrates. The reproduction also takes place by either the egg of the mother or the sperm of the father and began to grow when it is stimulated. Spontaneous generation is defined as the living creature that could arise from nonliving matter.
Answer:
They would not be able to achieve homeostasis.
Explanation:
Homeostasis refers to the maintenance of a stable internal environment and the cell needs a healthy and proper enzymes to do this.
