I found the exercise on the internet. Attached is the chart and the rows. On the left we have "plant tissue", then on the middle top - "dermal" - and just below - "ground". Straight in front of "ground", the term is "c<span>ollenchyma".
The correct row would be D.
1. is vascular because that's the other type of plant tissue besides the ones that are already present in the chart.
2. and 3. - s</span>clerenchyma and parenchyma - are indeed types of ground tissues next to collenchyma.
4. and 5. - x<span>ylem and phloem - are the types of tissues present in vascular plants, they work as vessels where water and nutrients are conducted.</span>
Answer:D Is the correct answer.
Explanation: All of the options could be the parents of the child with type O blood, because every type of blood has an O type in it.

Microorganisms can be divided into two groups:
1. Archea
• Archea are prokaryotic unicellular organisms without cell nucleus or other membrane bound-organelles.
• Their membrane is built from ether lipids, which differs them from bacteria’s cell membrane.
•
2. Bacteria
• Bacteria are also unicellular prokaryotic organisms.
• Bacterial cell membranes are made from phosphoglycerides with ester bonds. Bacterial genome is in a form of circular chromosome.
• They reproduce by binary fission or by budding.
Besides, prokaryotes (Archea and Bacteria) a large number of eukaryotes are also microorganisms. Unicellular eukaryotes contain organelles such as the cell nucleus, the Golgi apparatus and mitochondria. Usually, they reproduce asexually by mitosis. An example of eukaryotic microorganism is Protist.
