Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into ATP (adenosine triphosphate), and then release waste products. <span>There are </span>3 major<span> steps in </span>cell respiration:<span> glycolysis, Krebs Cycle, and the electron transport chain.</span>
Meiosis occurs in a series of different phases and creates genetically unique reproductive cells. The process which helps make meiotic cells genetically different and occurs during prophase I, but not during prophase II, is crossing over (C). Crossing over is the exchange of genetic material between two homogenous chromosomes. It is one of the final phases of prophase I. This process is called synapsis. It occurs when the matching regions on the matching chromosomes break and then reconnect to the other chromosome
Answer:
the right awnser is 3 b and 1 w vote brainliest this is right.
Explanation:
Answer:
he relationship between environment, variation and selection lay the foundation for natural selection and evolution.
Genetic variations are present among species due to number of reasons like recombination or crossing over during meiosis, mutations, random fertilization etc. These factors bring changes among the members of a species. Some of the species become better adapted to survive in a particular environment whereas some are not better adapted and become extinct over a period of time. The environment selects the organisms that are best adapted to survive and hence lead to variations.
