The male reproductive system has many roles, but two are: it produces, maintains, and transports sperm (male reproductive cells) and semen (the fluid which protects the sperm and allows it to swim to meet the female egg).  (continued answer in explanation)

Explanation:

One of many structures in the male reproductive system is the prostate gland. The prostate gland's most necessary feature is that it aids in creating fluid that, together with sperm cells from the testicles and fluids from other glands, makes up semen. The prostate also has muscles which ensure that the semen is vigorously pushed into, and then expelled from the urethra during ejaculation. One hormone in the male reproductive system is LH, or luteinizing hormone. It is made by your pituitary gland (a small gland located beneath the brain). LH plays a very important role in the sexual development and functioning of males. LH also plays a key role in gonadal (testicles) function.

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.
