The lungs are divided into seven lobes. Thus, the correct option is D.
<h3>
What is the function of lungs?</h3>
Lungs provides your body's cells with oxygen. When exhale, waste gases from body, including carbon dioxide, are removed. shields airways from irritants and dangerous chemicals.
Each lung has an oblique fissure, with a transverse fissure further dividing the right lung. The superior and inferior lobes of the left lung are divided by an oblique fissure. The superior, middle, and inferior lobes of the lungs are separated by an oblique and horizontal fissure. As a result, the left lung has two lobes whereas the right has three.
A lobar bronchus supplies each lobe. Bronchopulmonary segments that are supplied by segmental bronchi divide the lobes.

Answer:
2. This gives the worms two separate populations of offspring that have different chances of surviving. An added benefit of being a hermaphrodite is that if a worm never finds a mate, it can fertilize its own eggs and reproduce that way. Many hermaphrodites experience this benefit.
3. Surprisingly, earthworms have quite a few digestive organs in common with humans. Digestion starts in the mouth, which takes in soil. The food is then transferred to the pharynx, which swallows the dirt into the esophagus. Instead of a stomach, earthworms have a crop which stores food and connects to the gizzard.
Explanation:
4. Worm castings contain the worms' gut bacteria and mucus. These microbes and substances are very helpful to plants. Vermicompost has more nitrogen-fixing bacteria than conventional compost. Vermicompost helps make minerals in the surrounding soil available to plants more quickly.
5. Comparative anatomy is an important tool that helps determine evolutionary relationships between organisms and whether or not they share common ancestors. Anatomical similarities between organisms support the idea that these organisms evolved from a common ancestor.
In order to determine the volume at a given temperature, you may apply Charle's law, which states that for a fixed mass of gas held at constant pressure, the temperature and volume of the gas are directly proportional. Mathematically, this is:
V / T = constant
Therefore, if the initial volume and temperature are known, we may determine the final volume at 900 K.
It would be to wear protective clothing and gloves when transferring bacteria and fungi
