<span>The level of carbon dioxide in the atmosphere is maintained by several processes, including photosynthesis, respiration and combustion. Green plants remove carbondioxide from the atmosphere by photosynthesis. Living organisms - including allplants and animals - release energy from their food using respiration.</span>
<span>Platelets help prevent blood loss at sites of vascular injury. They form a pro coagulant surface and cause a thrombin generation and fibrin formation. In addition, platelet help with tissue repair and influence processes and help with inflammation and the immune response</span>
The answer is <span>C) crossing over.
</span>The crossover of chromosomes is the exchange of genetic material between homologous chromosomes. If it is known that homologous chromosomes are present only in the meiosis I, it is expected that crossover is occuring meiosis I.<span> Homologous chromosomes pair up in the prophase. Therefore, meiosis prophase I is the phase in which chromosomal crossover occurs. Chromosomal crossover is process that </span>helps make meiotic cells genetically <span>different.</span>
Answer:
<em>large</em><em> </em><em>range</em><em> </em><em>of</em><em> </em><em>phenotypes</em>
Explanation:
<em>shades</em><em> </em><em>of</em><em> </em><em>brown</em><em>,</em><em> </em><em>hazel</em><em> </em><em>greens</em><em> </em><em>and</em><em> </em><em>blue</em><em> </em><em>-</em><em> </em><em>they</em><em> </em><em> </em><em>are</em><em> </em><em>all</em><em> </em><em>part</em><em> </em><em>it</em><em> </em><em>could</em><em> </em><em>be</em><em> </em><em>multi-coloured</em><em> </em><em>.</em><em> </em><em>One</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>eyes</em><em> </em><em>could</em><em> </em><em>have</em><em> </em><em>hazel</em><em> </em><em>and</em><em> </em><em>the</em><em> </em><em>other</em><em> </em><em>could</em><em> </em><em>have</em><em> </em><em>shades</em><em> </em><em>of</em><em> </em><em>brown</em>
The atomic level would be melting point
