Answer:
Cells in a large multicellular organism communicate with each other by chemical signals. These signals are passed from one cell to another. To receive and respond to a chemical signal, a cell must have a <u><em>receptor</em></u> for that chemical.
Explanation:
To generate a physiological response, all cells in the body have special proteins called receptors. These receptors are involved in detecting a chemical signal and generating a response. The receptors are specific for different kind of chemical signals. For example, a dopamine receptor will bind a dopamine molecule whereas an insulin receptor will be able to bind an insulin molecule. Apart from chemical signals, some cells might also respond to mechanical signals.
Mitosis results in the formation of two diploid cells while Meiosis results to the formation of four haploid cells. Mitosis is a process that takes place in the somatic cells; a cell that has doubled its genetic material divides to produce two diploid daughter cells while meiosis is a process that take place in the gamete cells where a doubled cell undergoes two rounds of division producing four haploid cells.
The correct answer is C. "when Henry ask "what is different with this plant that does not grow very well compared with the other house plants?" "
Answer:
Uranus.
Explanation:
Uranus is also known as ice giants and the seventh planet of the solar system. The north pole and south pole of Uranus lies near to the equator.
The internal heat of the Uranus is least among all the planets. The clouds of Uranus are sharp, light and made of different chemical compositions.Methane clouds of the Uranus lies in the troposphere layer.
Thus, the correct answer is Uranus.
Answer:
D. Lactic acid
Explanation:
Fermentation takes place When a molecule of glucose is broken down into pyruvate molecules. Fermentation is another source of gaining energy from cellular respiration.
During fermentation, electrons from electron transport chain combine with pyruvate molecules, and this reaction further proceeds in the presence of endogenous organic electron receptors. These organic electron receptors form waste products.
Common products synthesized during fermentation are lactic acid, lactose, and hydrogen. Lactic acid is formed when NADH transfers an electron to pyruvate molecule.
