Well, biofuels burn cleaner (make less polution), they can be a lot more efficient, and we can have a supply of biofuel long after fossil fuels run out.

A teacher shows students a string of beads as a model of a chromosomes and genes. What do the beads represent? Explain
Elza [17]

Answer:

If the string of beads refer to a chromosome, then each bead is a gene responsible for one or more traits.

If the string of beads refer to a gene, then each bead refers to the sequence of nitrogenous bases in one strand of the gene.

Explanation:

A chromosome is composed of several genes.

A gene is composed of several nucleotides each containing a nitrogenous base. A gene is primarily made functional by the sequence of nitrogenous bases in its structure. If AGATTCA is a hypothetical sequence of the nitrogenous bases on one strand of a hypothetical gene then TCTAAGT will be the sequence of nitrogenous bases on the complementary strand of that particular gene.

Match the phase of mitosis with the event listed: 1. The genetic material is duplicated interphase 2. Chromosomes move to opposi
damaskus [11]

ANSWER: the genetic material is duplicated interphase.

The process by which a cell which has previously replicated chromosomes in the nucleus of the cell is separated into  two identical sets of chromosomes is known as mitosis. Mitosis is the division of the mother cell into two daughter cells,  these daughter cells are genetically identical to each other and to the parent cell. It is  a form of nuclear division.  Mitosis is generally followed by cytokinesis, this process divides the nuclei, cytoplasm, cellular organelles and cell membrane  into two cells of roughly equal shares of these cellular constituents. The M phase of the cell cycle is of mitosis and cytokinesis together. Cell division is a process with sequence of steps that enables organisms to grow and reproduce.  Genetic material is replicated in parent cells and is distributed equally to the two daughter cells.  Cells undergo a period of growth called interpahse before entering mitosis. During the interphase,  the genetic material replicates and the organelles prepare for division. In the process of mitosis,  the parent's cell genome is transferred into the two daughter cells. The daughter cells are similar to each other and to their parent cell.

The cell's genome is composed of chromosomes that are complexes of tightly coiled DNA that contain the genetic material which  is vital for the proper functioning of the cell.  

The process of mitosis begins when the chromosomes condense. In most eukaryotic cells,  the nuclear membrane segregates the DNA from the cytoplasm into membrane vesicles.  The ribosomes also dissolve, the chromosomes align themselves. Microtubules pull apart the sister chromatids of each chromosome.  The daughter chromosomes are pulled towards opposite ends. Nuclear membrane forms around the separate daughter chromosomes.  In animal cells, the area of cell membrane pinches inwards, to form the two daughter cells, the imaginary line is called the cleavage  furrow which separates the developing nuclei. In plant cells, the new dividing cell wall is constructed in between the daughter cells.  The parent cell will thus split in half and give rise to two daughter cells.
