Eukaryotic sexual life cycles show tremendous variation. Of the following elements, which do ALL sexual life cycles have in comm
larisa [96]

Answer:

II. meiosis

III. fertilization

IV. gametes

Explanation:

Gamete formation and fertilization are the processes performed by all the sexually reproducing organisms. Gametes are the cells that are formed in the male and female sexual organs of these organisms. Formation of gametes occurs by meiosis and therefore, the gametes of a diploid organism are always haploid.

Male and female gametes fuse during the process of fertilization and form the zygote which in turn divide repeatedly to produce an embryo. For instance, sperms and eggs are the male and female gametes that are formed in testes and ovaries of male and female human individuals respectively. The fusion of sperm and egg produces a zygote that finally develops into a young one.

2. Few, if any, liverworts, mosses or ferns are found growing in dry biomes. Why do you think this happens? Think about the biol
Makovka662 [10]

Answer:

See the answer below

Explanation:

<em>Liverworts, mosses, or ferns hardly grow in dry biomes because they require moist environment in order to successfully sexually propagate themselves.</em>

<u>During sexual reproduction, the male sperm requires water to swim and meet the female egg. This means that without water, fertilization cannot take place and sexual propagation will become impossible. This is unlike advanced plants in which there are various means by which the pollen can travel to meet the ovule.</u>

Hence, the group of plants in question hardly grow in dry biomes.
