Answer:
Chromosome crossing over in prophase 1 where DNA segments are moved between the homologous pair.
Explanation:
Soil composition would be best for availability of nutrients, water, and root development higher proportion of humus; lower amounts of clay and sand
Compared to the lower soil layers, the topsoil or surface soil often includes more organic matter and air but less clay. The topsoil typically has the highest concentration of plant roots and is more fertile than the other layers.
- Nutrient management includes managing the composition of the soil. Minerals, organic material, water, and air are the fundamental elements of soil. Typically, 45% of the soil is made up of minerals. 5% organic material 20–30% water and 20–30% air are used. At best, these percentages are merely generalizations.
- Numerous nutrients are found in soil, which are obtained from dead plants and animals. The plants eat these nutrients as nourishment. So soil contributes to the growth of plants by giving them sustenance in the form of nutrients.

Answer:
As a result of the Hershey and Chase experiments, scientists believe
that the “transforming principle” is DNA.
Explanation:
Hershey and Chase determined that DNA, not protein, was the inherent material. They resolute that a defensive protein coat was molded everywhere the bacteriophage, but that the interior DNA is what discussed its capability to produce offspring inside a bacterium. Transformation occurs when one bacterium picks up free-floating DNA and incorporates it into its own genome. When scientists first observed this behavior, it seemed that genes were transforming one type of bacteria into another, so they concluded there must be a 'transforming principle' at work.
Answer:
True
Explanation:
Sunburn (First-Degree Burns): A sunburn is skin damage from the sun's ultraviolet (UV) rays. Most sunburns cause mild pain and redness but affect only the outer layer of skin ( first-degree burn). The red skin might hurt when you touch it. These sunburns are mild and can usually be treated at home.
