Answer
At week 5-6 of gestation, the baby’s heart starts beating.
Explanation
Fertilization occurs in week 3 followed by implantation in week 4.In week 5 the levels of hormones increases with formation of the baby’s heart and circulation system. In week 6, the neutral tube closes followed by development of structures necessary to form eyes and ears. The head of the baby develops at week 7 followed by nose in week 8 and toes in week 9.
Answer:
From the Sun
Explanation:
Solar power is energy turned by the sun into thermal or electricity. The cleanest and most generous source of usable green energy is solar energy.
Solar energy, Solar radiation capable of heat creation, chemical reactions or power generation. The cumulative number of solar energy events on earth significantly exceeds existing and planned energy needs worldwide.
Answer:
Yes
Explanation:
I would support regulations banning the construction of cities near fault lines to save money and lives. Constructing cities away from fault lines would mean that if there was an earthquake, there would be less damage to the surrounding buildings and less money would be needed in repairs. People would generally be safer away from the earthquake because the people in the buildings near the fault line are likely to experience a building collapse.
Answer/Explanation: The Sun is still by far the most massive body in the Solar System (it contains more than 99.8% of all the system's mass).

Answer:
D. Biotechnology
Explanation:
Biotechnology is the use of biological processes, living organisms, or biological systems to manufacture useful products in order to improve the quality of human life.
Biotechnology covers many disciplines such as genetic engineering, biochemistry, molecular biology, medicine, agriculture etc. In medicine, biotechnology has been applied in the development of medicines and therapies, etc. In agriculture, biotechnology is applied in the development of genetically modified plants, biofuels, biological treatment as well as to solve other agriculture-related issues. In the industries, through genetic engineering, simple cells and proteins has been engineered to produce useful chemicals such as drugs, hormones, etc.
Since George's studies involves cell culturing and genetics of plants in order to develop technology that will improve plant production and solve other agriculture-related problems, he is studying Biotechnology.
