Answer:
meiosis I
Explanation:
Reduction of the number of sets of chromosomes occurs during meiosis I.
During Meiosis I crossing over of genetic material occurs between chromosome pairs
Answer:
Food made by plants can get used by plants or by other animals as plants maybe eaten by other organisms that feed on plants by living on them, these organisms are called parasites. Or else the food can be used up by plants to carry out their metabolic activities ( activities at cellular level which keeps the plant alive ) like cellular respiration
A gene is a variant of an allele.chromosomes have the same genes, but might have different versions of those genes. The different possible versions of the genes are called alleles.
Answer:
<u>Pathway A and B</u> are <u>anaerobic</u> ways of extracting energy (ATP) from glucose. These pathways are advantageous when little or no oxygen present. The net energy in both pathways is 2ATP. Both pathywas take place in the cytosol of the cell and are categorized as fermentation.
<u>Pathway C is aerobic</u> in which oxygen is used to yield energy (ATP). This pathway is advantageous when energy needs are high because it produces 36 molecules of ATP. Therefore, net energy in this pathway is higher than the anaerobic pathways. This pathyway takes place within the mitochondria and is recognized as cellular respiration.
A schematic illustration can be seen in the image attached.
PS: <u>Glycolysis</u> is common to fermentation and aerobic respiration.
