Crossing over happens in Meiosis 1 only. In Prophase 1 a cells chromatin (chromatin = chromosomes that have not condensed yet) condense and pair up forming homologous chromosomes (paired = XX (2 chromosomes together)). When this happens segments/ alleles of the chromosomes pairing up swap over. This creates genetic diversity as each chromosome is different, it has parts from its pair. This leaves every chromosome unique and individual.
I hope this helps, sorry some of the vocab is rather technical. By the way I would suggest watching the
'Crash Course: Meiosis' on YouTube, this really helped me when I was learning this topic. :D

The conclusion that can be draw from the data above concerning the carnivores and the herbivores is that the carnivores have shorter digestive system than the herbivores. That is option C.
<h3>What are carnivores and herbivores?</h3>
The carnivores are those animals that kill and feed on other smaller animals as their source of food while the herbivores are the animals that feed on plant and plant products.
From the data given above, the herbivores have longer digestive system but are less heavy in weight as when compared with the carnivores.
Also from the data given above, the carnivores have a shorter digestive system but with more weight than the herbivores.

Answer: A new study in the journal Biotechnology for Biofuels has found that those wasted watermelons could be turned into up to 2.5 million gallons of ethanol. It turns out that watermelon juice is a great base to make ethanol from -- it's full of sugar and yeast-friendly amino acids.

Answer:
Medulla oblongata
Explanation:
Medulla oblongata is found at the lower half of the brainstem continuous with the spinal cord. The medulla oblongata controls the center of vomiting, vasomotor centers for regulating heart rate, cardiac, respiratory and blood pressure. Furthermore, Medulla oblongata connects the higher levels of the brain to the spinal cord and also controls autonomic functions.
