Answer:
The lactose operon (also known as the lac operon) is a set of genes that are specific for uptake and metabolism of lactose and is found in E. coli and other bacteria.
Explanation:
HIH.
Encoding, storage, and retrieval are the three stages involved in
remembering information. The first stage of memory is encoding. In this
stage, we process information in visual, acoustic, or semantic forms. This lays
the groundwork for memory.

When the ground subsides it can become lower than the surrounding terrain, forming a basin.
Since water, which carries sediment, flows downhill, sediment will collects in these basins.
If enough sediment collects, compaction and cementation will turn it into sedimentary rock.
Many plants have modified stems that serve various purposes, including storage, protection, photosynthesis, support, propagation, and perennial growth.
<h3>What are the functions of modified stems, and explain them with examples?</h3>
Underground Stem Modifications:
- These can be found underground, as their name suggests. They have a variety of uses, including food storage, reproduction, and perpetuation. By having nodes and internodes, they may be distinguished from roots. They support asexual reproduction and the plant's ability to endure a period of hibernation. They offer a defense against animal grazing and environmental stress.
- Rhizome: It runs parallel to the ground, and its lower portion, capable of producing adventitious roots, can also generate scaly leaves. They have internodes, buds, and nodes. Examples: Turmeric and ginger. The rootstock in bananas is a rhizome that develops vertically.
- Bulb: Modified bulbs are visible, and the stem is shortened and ringed with scale leaves. Examples: Tulips, Lilies, Daffodils, Onion, Garlic
- Corm: A short erect stalk with scaly leaves covers it. When compared to bulbs, it is tough. Examples: Colocasia, Yam, Saffron
- Tuber: The fleshy, food-storing stem terminal is present in this instance. Nodes and internodes are present in the stem; however, they are not identifiable because of swelling. Scaly leaves present at nodes can be interpreted as eyes or scars. Examples: Potato, Artichokes.
