Answer:
Eggs are developed and released by the <em>ovaries.</em>
Sperm is produced by the <em>testes</em>.
Explanation:
Ovaries are the site in females where the production of egg takes place. After the formation of an egg, the egg is transported to the fallopian tube, where it might undergo fertilization if a sperm unites with it.
Sperms are the male reproductive cells which are produced by many animals. The sperms are produced in the testes of males.
The sperm and the egg unite to form a fertilized zygote.
Answer:
The correct answer will be- proteoglycans and the glycoproteins
Explanation:
The connective tissue forms a very large proportion of the total mass of a body. The connective tissue plays a distinct role in the body like the movement of the cell, mechanical support, wound healing but the main role is to connect different tissues of the body.
The property of the connective tissue is determined by the amount and type of the extracellular matrix present which contains three main components which are the fibres like collagen, glycoproteins and the proteoglycans.
Thus, proteoglycans and glycoproteins are the correct options.
Cat (Australia); lots of cats became feral and they reproduce very fast. They became the apex predator and the native species have no defense system for them, so the cats brought tens of species on the verge of extinction (mainly placental mammals).
Fox (Australia); became an apex predator in the lack of competition, and damages the populations of native small placental mammals.
Hair (Australia); reproduces much quicker than the native species of mammals, increased significantly in numbers, and out competes the native species for the food sources.
