Answer:</h2>
<u>A. Crossing-over between homologues.</u>
<h2>
Explanation:</h2>
In meiosis and mitosis, recombination happens between comparable particles of DNA (homologous groupings). In meiosis, non-sister homologous chromosomes pair with each other so recombination ordinarily occurs between non-sister homologs.
All living organism reproduces either through asexual reproduction or sexual reproduction or sometimes through both mode of reproduction. In both cases let it be sexual or asexual, the mode of cell division namely meiotic and mitotic cell division, the recombination between homologous chromosomes is a typical system utilized in reproduction.
Answer: A) changing the rate at which greenhouse gases are released from Earth's surface into the environment.
Explanation: Without vegetation (For example trees) the rate at which greenhouse gases, like carbon dioxide, are released from Earth's surface into the environment would skyrocket. Vegetation uses carbon dioxide in photosynthesis and converts it into oxygen, helping to absorb some of the greenhouse gases that would otherwise accumulate in our atmosphere. It essentially reduces the rate at which greenhouse gases are released into our atmosphere.
CO2 is a normal waste that normally diffuse across placenta from embryo to the mother.
