Capillaries; veins; arteries
Capillaries allow materials to be exchanged between the blood and tissues, veins carry blood towards the heart, and arteries carry blood away from the heart.
Capillaries are small blood vessels through which molecules such as oxygen and glucose enter the cells.
Veins are tubes or blood vessels that transport blood toward the heart. Veins mostly transport deoxygenated blood towards the heart except the pulmonary and umbilical veins, which transports oxygenated blood toward heart.
Arteries are blood vessels that transport blood away from the heart to other parts of the body. Arteries have elastic walls and they are stronger and thicker than veins.

According to Peter Berger, there are four major characteristics of modernization which are an expansion of personal choice, increasing social diversity, growing awareness of time and orientation towards the future, and decline of traditional and small communities.
Dr. Berger made significant contributions to the field of sociology of knowledge, which studies how society shapes human thought.
He saw collectivism as intrinsically tied, as well as socialism and dictatorships.
According to Peter Berger, there are four major characteristics of modernization which are
Thus, these were the major characteristics of modernization.

phytoremediation
herbicide tolerance
gene transfer to nontarget species
Answer:
The answer is D. Gene transfer to non-target species.
Explanation:
Using DNA technology we have made several genetically modified crops called GM crops. But sometimes the transgenic trait or gene may effect the non-target species. For example Bt-crops were found damaging the soil health. These pest resistant Bt-crops release Bt toxin near the soil root zones. High levels of Bt toxin can affect the health of soil as well as the soil insects. Hence GM crops must be monitored for the effects on non-target species.
Answer:
The correct answer is: Gene transfer to non-target species. It is believed within the scientific field that these risks directly affect environmental impacts and need to be assessed on a case by case basis and recommended post-release ecological monitoring.
Explanation:
Transgenic crops could possibly entail positive or negative indirect environmental effects through changes in agricultural practices such as pesticide and herbicide use and cropping patterns. Agriculture affects the environment it does not matter which type we are talking about. Then it is normal to conclude that the use of new genetic techniques in agriculture will also affect the environment.
