Answer: C) ciliates.
Explanation: Ciliates possess two different nuclei a diploid micronucleus which carry the germline of the cell. It also has a large, polyploid macronucleus which can be termed the vegetative nucleus, it takes care of general cell regulation, it expresses the phenotype of the organism. The macronucleus is generated from the micronucleus. The micronucleus passes the genetic material to offspring, but it does not express its genes. The macronucleus provides the small nuclear RNA for vegetative growth.
Bacteria is the domain of prokaryotic organisms that are considered to be true bacteria, and Archaea is the domain of prokaryotic organisms able to live in extreme environments. Eukarya differs from the prokaryotic domains in basic characteristics of cellular organization, biochemistry, and molecular biology. Further, unlike the prokaryotic organisms, many of the Eukarya are truly multicellular. Eukaryotic cells,which are structurally more complex than prokaryotic ones, have many of their cellular functions segregated into semiautonomous, membrane-bound cell regions, called organelles. The principal organelle is the nucleus, which contains the geneticmaterial, deoxyribonucleic acid (DNA). In prokaryotic organisms, in contrast, the DNA is not segregated from the rest of the cell. Other distinguishing organelles in eukaryotic cells include the mitochondria. These are the sites of respiration, in which energy is generated by breaking down food, in the presence of oxygen, into water and carbon dioxide. The plants and the algae have additional organelles, the plastids.
Based on the symptoms, the most likely cause of the problem is formaldehyde used in the building materials.
<h3>What is formaldehyde?</h3>
Formaldehyde is a chemical substance which is used as. preservative of wood and building materials.
It us also present in binders and adhesives.
Exposure to formaldehyde produces adverse effects such as;
- watery eyes
- burning sensations in the eyes, nose, and throat
- nausea and
- skin irritation, etc.
Therefore, based on the symptoms, the most likely cause of the problem is formaldehyde used in the building materials.

Answer:
A (bean)
Explanation:
Leguminous plants are plants that belong to the family FABACEAE and characterized by their possession of pods as fruits and ability to form nodules in their root for a symbiotic relationship to occur between nitrogen-fixing plants. An example of these leguminous plants that can be found in the option is BEAN.
Bean plant like all other legumious plants host certain bacteria called NITROGEN-FIXING bacteria in their roots in order to help them convert Nitrogen gas into usable compound forms. They, in turn produce carbohydrates for the bacteria. Leguminous plants store this nitrogenous compounds in their root nodules.
