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:
exposed ovules
Explanation:
Gymnosperms are a type of flowerless plant that tend to produce cones and seeds. This is why the name refers to "naked seed", seeing since the gymnosperm seeds are not positioned within an ovary. Therefore the presence of exposed ovules or the structure that contains the seeds in a place would immediately indicate that this is, in fact, a gymnosperm.
What organ integrates the brain nervous organs with the endocrine system? Hypothalamus
Answer:
Option (2) and (3).
Explanation:
Cancer is the uncontrolled division of the cell that might results in the loss of apoptosis in the cells. The cancer cell shows the property like angiogenesis and loss of contact inhibition.
Both the hereditary factors like mutations in some gene and environmental factors like any mutagen may inhibit the process of the cell division. Both these factors mainly inhibits the gene that are responsible for the regulation of the cell cycle like p53, Rb.
Thus, the correct answer is option (2) and (3).
It is 0%. They only have the recessive alleles (ss) so there is no possibility it can ever produce a gamete with a dominant allele (S). For example, if it was Ss it would be 50%, and for SS it would be 100%.
