Answer:
Two technologies that can benefit the developing countries are:
Recombinant DNA technology or genetic engineering: As researches show, the population of most of the developing countries is far more than the resources the country can produce. Techniques of genetic engineering can help in crop production so that the food needs of these countries can be solved, Also, genetic engineering is helpful in may aspects like health, bio-remediation.
Nanotechnology: The development of nanotechnology can help the developing countries in many ways such as the development of better and efficient fuels for the country.

Answer:
The correct answer is violet/ purple.
Explanation:
Gram staining is performed to distinguish between gram-positive and gram-negative bacteria. The first stain or dye which is used in gram stain is crystal violet. So after adding this dye, all cells will be colored purple.
So when we stop after the addition of first dye then all the cells will appear purple/violet because all the cells will contain crystal violet in its cell wall which can be seen under the microscope. So we will not be able to distinguish between gram-positive and gram-negative bacteria. So the correct answer is purple.
The correct answer is - D. Biodiversity resulting from few ancestors.
The adaptive radiation is an evolutionary process in which diversification is appearing among a species, and it starts to fill in different ecological niches.
The adaptive radiation occurs when a species starts to evolve into multiple different species. The reason for the diversification is available space in the ecologic niches. The members of the initial species, start to exhibit new behaviors, new ways of feeding, change in coloration, all in order to be better suited for a specific ecological niche.
