Answer:
The correct answer is - option B. it increases the amount of genetic variation in the species.
Explanation:
Meiosis is a type of cell division that takes place in sex cells or reproductive cells. There is crossing over takes place which is a process where the genetic exchange of chromosomes occurs between non-sister chromatids of homologous chromosomes.
The crossing over leads to the new genetic combinations of genetic material which result in the genetic variation in species. This variation plays a role in the natural selection and evolution of species.
The answer is C, serve a different function.
In multicellular organisms, same types of cells makes up a tissue, and tissue makes up organs, then eventually organs work together as an organ system.
For example in humans, stomach cells makes up the stomach tissues, and stomach tissues makes up the stomach. stomach can help digest food and mix food molecules together. But in opposition, red blood cells is present in the blood tissue, however, their function is not to digest food, but is to transport oxygen.
Therefore, we can see that different cells serve a different function.
Answer:
When Glucose is in short supply.
Explanation:
Ketone bodies are produced in mitochondria of liver cells to augment the shortage of glucose in the body. Shortage of blood sugar glucose can occur due to fasting, rigorous exercises or medical conditions.
