Answer:
The factors that should be kept in mind while implementing green roofs are discussed below:
Explanation:
1. Green roofs comprise of two kinds: the intensive roof and the extensive roof. Intensive roofs are capable of growing any kinds of plants on it but they need to be well maintained. Extensive roofs are lighter and do not need much maintenance and very few kinds of plants would be capable to grow on it.
2. The slope of the roof should be either flat or just inclined at an angle of 30 degrees to support the growth of plants.
3. You should have the fact in mind that your roof should acquire enough light from the sun for the growth of the plants.
4. Waterproofing of the roof should be done according to the climate conditions.
Answer:
embryonic development
Explanation:
other non aquatic vertebrates exhibit gill slits even though they never breathe through gills. These slits are found in the embryos of all vertebrates because they share as common ancestors the fish in which these structures first evolved.
An operon is a stretch of DNA consisting of an operator, a promoter, and genes for a related set of proteins, usually making up an entire metabolic pathway.
operon is a functional unit of gene.
This cluster of gene transcribed together to give a messenger RNA which further give rises to protein.
operator in operon is the site where repressor binds.
promoter is where Mrna binds , where our genes are transcribed
structural genes, they code for the enzyme that are involved in this metabolic pathway.
Operons have an important role to play as they produce protein for the cell this serves them energy, the protein is produced only when energy is required.

Answer:
The correct answer is option c. "adaptive radiation".
Explanation:
The term "adaptive radiation" is used in evolutionary biology to describe a evolutionary history at which many different organisms are created as a result of a rapid diversification of an ancestral species. This phenomenon takes place as a result of changes in the environmental conditions that forces new species to adapt quickly. The scientist observations of many intermediate forms at different continents of an ancestral reptile, most strongly support the evolutionary model of adaptive radiation.
