Answer: 2. Each subunit represents a separate polypeptide chain, while one polypeptide chain may contain several domains.
Explanation: Each subunit constitutes of one polypeptide chain. A polypeptide chain has one particular gene coding for it. thus it simply implies that a protein must have one gene for each subunit.
Many proteins is made up of different protein domains. A particular domain may appear in a variety of different proteins.
domains are stable on there own, they can be exchanged via genetic engineering between one protein and another.
Non-prokaryotic organisms typically have two life cycle stages: trophozoite and cyst is Protozoa.
<h3>What is Protozoa?</h3>
- Protozoa is a group of single celled, non- prokaryotic organisms.
- These may either be free living or parasitic in nature.
- These are heterotrophs and reproduce asexually by binary fission.
- The Protozoa consists of many unrelated or loosely related organisms.
- They are divided into four major groups: Sarcodina, Flagellates, Ciliates and Sporozoans..
- Some protozoa consist of two phases in their life cycle: proliferative stage (trophozoites) and resting stage (cysts).
- Trophozoites consists of the proliferative stage in which the protozoa divides and reproduces.
- The resting cyst form helps the protozoa to survive harsh environmental conditions like harmful chemicals, extreme temperature and nutrient and water deficiency.

Answer:
Roots. Roots are simple tissues that are derived from the stem of the plant.
Xylem. The xylem is tissue that transports water throughout the plant.
Phloem. The phloem is the plant's food transportation system.

The correct answer is: <em>tibia</em>
The femur, also known as the thigh bone, is one of the longest bones of the human body. The distal point of the femur refers to the area furthest away from its point of attachment, which in this case is the hip joint (please refer to the attached image). When referring to the image, you can see that the distal end of the femur articulates with the bone known as the tibia or shin bone. The tibia is the larger of the two bones located at the distal end of the femur. The tibia includes the knee and ankle joints. Therefore, the bone that articulates with the distal end of the femur is the tibia.
