In animals meiosis results in gametes and fertilization result in what?
Fertilization results in a zygote which turns into an embryo, then a fetus, and then a baby -insert animal species here.-
How does the alternation of meiosis and fertilization in the life cycles of sexually reproducing organisms maintain the normal chromosome count for each species?
Simple, Meiosis reduce the chromosome number in half while fertilization doubles the chromosome number. n=chromosome number Meiosis = 2n (primordial germ cells) ----> n (sperm cell/egg cell/polar bodies) Fertilization = sperm (n) + egg (n) ----> 2n (zygote)
Why must the life cycle of sexually reproducing species alternate between haploid and diploid stages?
Meiosis maintains the normal diploid number by halving the number to make the gametes and then allowing the diploid number to be restored through fertilization. For example in humans: Germ cells undergo meiosis --> Sex reproduction 2n germ cells --> 1n gametes --> 2n fertilization
What life function is necessary to the species but not the individual organism?
Reproduction
The fusing together of two gametes at fertilization is?
Gametes fuse together during fertilization.
The process of meiosis and fertilization help ensure the survival of the species by providing each generation with the same number of?
chromosomes

Why fertilized human is important?
Fertilization is important so species can have genetic variation. It is also important so the species can pass on their genes.

Both meiosis and fertilization are essential to maintain chromosome number constant .why?
Total number of chromosomes remain same in same species of organism through meiosis process. In meiosis process the number of chromosomes are reduced to half as a result in gametes only one set of chromosomes will be present. In this process chromosomes are same.....
What will happen if meiosis did not occur in sexually reproducing organisms?
If meiosis did not occur then the chromosome number would double each generation, and the cell could not survive with this increasingly larger number of chromosomes.
What is the purpose of reproductive system of female?
Reproduction is important to the survival of evey species
What is the purpose of the female reproductive systems?
Reproduction is important to the survival of evey species
Why is seed dispersal is important?
To expand the natural range of the plant species.
Is there external fertilization with live birth in fish?
In some species there is external fertilization. In other species there is live birth. Live birth requires internal fertilization.
Why is the fertilisation is very important for the life?
Answer: to make babies hope this helps :-) Answer: It is and it isn't. Fertilization occurs when sperm and egg meet and conception occurs. Without this, there is no reproduction, and no reproduction equals the death of a species. Humans would cease to exist if fertilization would cease to happen. There are large controversies over fertilization (and medical interference) because questions of religion, ethics, and morals are tied closely to the belief we are (or aren't) special as a species. Fertilization appears to be a supernatural process because some people believe that "the soul starts as the egg is fertilized." The actual physical process of fertilization is trivial, it's a natural biological process that all mammals (and most animals) share.
