Second option/ the gametes produced by meiosis allow for closing organisms
Answer:
Explanation:
Compact bone aka cortical bone is a dense, solid and rigid in which bony matrix with ground org. Substances and salts densely filled and leave tiny spaces known as lacunae. These spaces contain osteocytes also called as bone cells. Inside of these osteons there is a central canal which supplies blood vessels and nerves within bone. These vessels provide blood to the spongy bone and living cells housed within compact bones.
Structure of Compact bone: Basic unit of Compact bone is called osteon also known as haversian system. Each osteon consist of four parts.
1. Haversian canal which consists blood vessels and nerves acts as a site of hematopoiesis which is one of the functions of Compact bone.
2.lamellae are concentric rings of strong matrix consisting Calcium and phosphorus. this gives the bone its strength and hardness to bear body weight.
3.Lacunae contains osteocytes.
4.Canaliculi links osteocytes and provide route for nutrients to reach osteocytes.
<span>The bottleneck effect is the cause of the sudden shift in the genetic information of the population. Due to the landslide, suddenly high number of the members of the main population died, and this caused genetic drift for reducing the variation in the existing generation, which is now widely different from the original one.</span><span />
Color, smell/ odor, taste
Answer:
The correct option is c ( <span>sexual reproduction joins two cells that each have half the total chromosome number).
Reason:
Meiosis occurs only in reproductive cell in which the number of chromosome reduce to half. This phenomenon is very imoportant and essential for maintaining the number of chromosomes in species.</span><span />
