1 answer:
yan [13]2 years ago
3 0

Answer:

Last answer

Explanation:

The first 3 answers can be thrown out by process of elimination.

Answer 1 can't be right because no human has been on Mars.

Answer 2 can't be right because the space shuttle launch came after the last humans were on the moon.

Answer 3 can't be right because again the space shuttle didn't come around until long after the last human was on the moon.

So the only possible answer has to be the last.

Alternation of generation
Nastasia [14]

Answer:

The answer to this question is given below in this explanation section.

Explanation:

                    "Alternation of generation"

Alternation of generations is the type of life cycle that occurs in those plant  and algae in the archaeologist and the heterokontophyta that have distinct haploid sexual and diploid asexual stages.In these groups a multicellular haploid gametophyte with n chromosomes alternates with a multicellular diploid sporophyte with 2n chromosomes made up of n pairs.A mature sporophyte produces haploid spores by meiosis a process which reduces the number of chromosomes to half from 2n to n.

Two haploid spores germinate and grow into a haploid gametophyte.At maturity ,the gametophyte produces gametes by mitosis which does not alter the number of chromosomes.Two gametes from different organism of the same species fuse to diploid zygote,which develop into a diploid sporophyte . This cycle from gametophyte to sporophyte in the way in which all land plant and many algae undergo sexual reproduction.
