In seed plants, what is an important difference between gymnosperms and most angiosperms?

a. gymnosperms rely on animals to carry pollen from the female gametophyte to the male gametophyte, while angiosperms rely on wind.
b. gymnosperms require water for sperm to travel from the male gametophyte to the female gametophyte, while angiosperms do not rely on water for fertilization.
c. in gymnosperms, male gametophytes and female gametophytes are produced in different structures, while in angiosperms they are usually produced in the same structure.
d. both gymnosperms and angiosperms produce seeds on the scales of cones, but angiosperms have flowers.

Seen in some gram-positive bacilli, occurs when only the inner portion of a cell wall is deposited across the dividing cell. this new cross wall puts tension on the outer layer of the old cell wall. eventually, the outer wall breaks at its weakest point with a snapping movement that tears it most of the way around. the daughter cells can then remain hanging together almost side by side being held by a small remnant of the original outer wall. choose from the following statements the ones that correctly discuss reproduction using binary fission in a bacterial cell. select all that apply. view available hint(s) select all that apply. due to the stretching of the cytoplasmic membrane, both cells will contain a complete genome. each daughter cell will contain an equal number of organelles. the daughter cell will be a permanently smaller copy of the mother cell but will contain a complete genome. each daughter cell is an exact copy of the other, both genetically and morphologically

This is a typical grassland food web. it is also a small picture of an important cycle on earth: the carbon cycle. describe how the carbon gets into this food web. a) bacteria and fungi, the decomposers, recycle carbon from dead organisms. b) carbon is found in the grass and is passed from one level to the next in this food web. eliminate c) all living things give off carbon dioxide as a by-product of respiration and it is released into the atmosphere. d) plants use carbon dioxide as a reactant in photosynthesis, to make usable chemical energy in the form of a sugar.
