Answer:
Sexual Reproduction. ... Organisms that reproduce sexually by joining gametes, a process known as fertilization, must have a mechanism to produce haploid gametes. This mechanism is meiosis, a type of cell division that halves the number of chromosomes. Meiosis occurs only in gamete producing cells within the gonads.
Explanation:
Meiosis: A type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores.
<span>Mitosis:<span> A type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.</span></span>
<span>Heredity: T<span>he passing on of physical or mental characteristics genetically from one generation to another.</span></span>
From the
books of Geography Seattle is well known for its rain and dark, gloomy skies, but
it may surprise many how pleasant the weather can be, particularly during the
summer months. Using data from meteorological services for the past 50 years,
we can conclude that November through March brings cool temperatures, heavy
cloud cover and rain falling on most days. The coldest month is January with
average lows in the mid to upper 30s F (about 3°C). Weather is pleasant from
April through October, with the best weather in July and August when highs
average in the 70s and rain is uncommon. Skies are mostly clear and smog-free,
though mornings can produce an on-shore flow resulting in low clouds and fog
which typically burns off by mid-day.
Does Natural selection or evolution involve with this? it sounds like spiders and other Insects or bugs that have evolved to be able to have limbs in order to survive in a environments that would require extra limbs. probably from genes being passed on and also being mutated positively in order for the newer species to better adapt. the pair of legs could have been increased because of the environment that requires it and also as the mating changes it's basically survival of the fittest.
