Answer:What can we observe in order to visualize mendel's law of segregation ?
During meiosis I the homologous chromosomes separate.
Explanation:As stated by mendelev that "allele pairs separate or segregate during gamete formation..."
meiosis is the basis in the formation of sex cells.
we can see like wise in meiosis I as homologous chromosomes separates.
Answer:
have the same number of electron energy levels
Explanation:
All of the elements in the same period have the same number of atomic orbitals that are occupied by electrons that are in constant motion. For example the elements in the first period have one orbital for its electrons. The elements in the second period have two orbitals for their electrons. As you move down the table, every row adds an orbital. At this time, there is a maximum of seven electron orbitals.
<span>Protoplasm, or cytoplasm as others call it, is essentially all the fluid within the cell. Since a cell is a living organism, nothing is static. It is constantly creating chemicals and nutrients, and excreting waste. We only know that the protoplasm consists mainly of nucleic acids, proteins, lipids, carbohydrates, and inorganic salts. This is a very large and varied mix of materials and chemicals, which again is constantly changing because of cell activities, diseases, and environmental factors. Thus, it is impossible to find the specific chemical composition and nature of protoplasm.</span>
The cell membrane is a biological membrane that separates the interior of all cells from the outside environment. It consists of a lipid bilayer with embedded proteins. The basic function of the cell membrane is to protect the cell from its surroundings. The cell membrane controls the movement of substances in and out of cells and organelles. In this way, it is selectively permeable to ions and organic molecules. In addition, cell membranes are involved in a variety of cellular processes such as cell adhesion, ion conductivity and cell signalling and serve as the attachment surface for several extracellular structures, including the cell wall, the carbohydrate layer called the glycocalyx, and the intracellular network of protein fibers called the cytoskeleton. In the field of synthetic biology, cell membranes can be artificially reassembled.
