why practical sciences is often left out by teachers ?
Answers
Practical sciences are sometimes left out by teachers due to limited time and resources in educational institutions and may prioritize theoretical knowledge over practical application.
Additionally, practical sciences often require specialized equipment, facilities, or materials, which may not be readily available in schools. Moreover, teachers may feel more comfortable with traditional teaching methods and may lack the training or expertise to effectively integrate practical sciences into their curriculum.
Standardized tests and assessment frameworks that focus on theoretical concepts further discourage the inclusion of practical sciences. However, recognizing the importance of hands-on learning experiences, efforts should be made to bridge this gap and promote the integration of practical sciences into educational settings.

evolutionary significance of bryophytes
Answers
The bryophytes, which include mosses, liverworts, and hornworts, have significant evolutionary significance in the plant kingdom despite their relatively small size and simple structure, they played a crucial role in the colonization of terrestrial environments and the subsequent evolution of higher plants.
Here are some key evolutionary significance of bryophytes:
Adaptation to land: Bryophytes are considered some of the earliest land plants.
They were the first plants to transition from aquatic to terrestrial habitats, paving the way for the colonization of land by other plant groups.
They developed strategies to overcome challenges such as desiccation, limited nutrients, and anchorage to the soil.
Moisture retention: Bryophytes have adaptations that enable them to retain moisture.
They possess specialized structures, such as rhizoids and mucilage, that help absorb and retain water.
This ability to retain water and survive in relatively dry environments was an important adaptation for the conquest of land.
Soil formation: Bryophytes, especially mosses, contribute to soil formation.
They can grow on bare rocks and soil, where their rhizoids aid in weathering and breaking down substrates.
Their decomposed remains also contribute organic matter to the soil, enriching its fertility.
Habitat creation: Bryophytes provide habitat and microenvironments for other organisms.
Their dense mats or cushions create shelter, moisture, and temperature buffering for a variety of organisms, including insects, small invertebrates, and microorganisms.
They contribute to the overall biodiversity and ecosystem functioning.
Reproductive strategies: Bryophytes have unique reproductive strategies. They produce spores that can disperse and colonize new habitats.
Their reproductive structures, such as gametophores and sporophytes, exhibit various adaptations that allowed for successful reproduction in terrestrial environments.
Ecological indicators: Bryophytes are sensitive to environmental changes, making them valuable ecological indicators.
Their presence, abundance, and diversity can indicate environmental conditions such as air quality, moisture levels, and habitat disturbance.
Monitoring bryophytes can provide insights into the health and integrity of ecosystems.

Residual parent material refers to the *weathered rock* and *soil* that remains in its place of origin, while *transported parent material* is material that has been carried and deposited by natural agents such as water, wind, or glaciers.
The impact of these different types of parent material on *soil formation* can be significant. Residual parent material tends to contribute to the formation of soils with characteristics similar to the parent rock. The weathering process breaks down the rock into smaller particles, allowing for the development of soil horizons and the release of minerals that influence soil fertility. In contrast, transported parent material can introduce a diverse range of materials to a given area, leading to variations in soil composition, texture, and fertility. The transportation process can mix different types of sediment, resulting in the formation of heterogeneous soils with varying properties.
Answers
Residual parent material is the rock and soil that is still located in its original location and is weathered. Transported parent material is material that is carried and deposited by natural agents such as water, wind, or glaciers. The effect of these different types of parent material on soil formation can be significant.
Residual parent material usually contributes to the development of soils with qualities similar to the parent rock. The breakdown of rock into smaller particles through weathering enables the formation of soil horizons and the release of minerals that influence soil fertility.
The physical and chemical characteristics of soils derived from this form of parent material are often similar and homogeneous, allowing for predictable fertility and properties. Transported parent material, on the other hand, can introduce a diverse range of materials to a given area, resulting in variations in soil composition, texture, and fertility.
The transportation process can blend different types of sediment, resulting in the formation of heterogeneous soils with different characteristics. Transported parent material can also be exposed to weathering processes, altering its original composition and resulting in soils with varying degrees of fertility.
While transported parent material can increase the diversity of soil properties in an area, it can also make it difficult to predict soil characteristics, particularly in areas where different types of sediment have been deposited. The relationship between parent material and soil development is complex, with both the initial characteristics of the material and the surrounding environment influencing soil properties.
In general, residual parent material contributes to the development of homogeneous soils with predictable properties, while transported parent material can result in more diverse and heterogeneous soils.

You are studying an alien bacteria-like organism isolated from the clouds of Venus. You decide to repeat the Meselson-Stahl experiment to find out how it replicates its DNA. This time you plan to grow the cells on light 14N medium for many generations first. Then, you plan to transfer them to heavy 15N medium and allow them to grow for 2 additional generations (2 rounds of DNA replication). If the alien replicates its DNA via the conservative model of DNA replication, what is the expected distribution of DNA in the density gradient after two rounds of replication
Answers
Answer:
it is expected to observe two bands: one band of light density and one band of heavy density
Explanation:
DNA replication is semiconservative because when DNA is replicated both resulting DNA molecules are composed of one original strand and one newly synthesized strand. If DNA replication would be conservative, then the original DNA molecule would serve as a template to produce a new DNA molecule, thereby each cell division would produce one daughter cell with a new DNA molecule and one daughter cell with the original DNA molecule of the parental cell. In this case, the transfer of bacteria-like organisms into a heavy 15N medium would produce two types of DNA cells after replication: cells with original DNA of light density (14N) and cells with new DNA of heavy density (15N), which would be distributed in two bands after centrifugation.
