Double fertilization is typical of angiosperms. One of the sperm cells produced by the pollen grain fertilizes the egg. What is the function of the second sperm cell? The second sperm cell forms the pollen tube.

The second sperm cell develops into the seed.

The second sperm cell contributes to the development of triploidendosperm tissue.

The second sperm cell ripens into a fruit.

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.

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.

your spelling is a little off : ]

i think its white blood cells

i hope this
