Answer:
active; prokaryotes
Explanation:
Active transport can be defined as the movement of molecules across cell membranes against a concentration gradient, i.e., from a region of low concentration to a region of high concentration. Group translocation is a specialized type of active transport observed in prokaryotic cells. In group translocation, the transported substance is chemically modified during its movement, thereby the cell membrane becomes impermeable to this substance once it is within the cell. In bacteria, the phosphotransferase system is a type of group translocation that uses phosphoenolpyruvate (PEP) as a source of energy to transport sugar molecules into the cell.
Answer:
While I enjoy going to school, I love the two month-long summer vacation as much. I get to do many interesting activities. I get enough free time during the vacation to pursue my hobbies of reading and playing the guitar.
During my summer holidays my parents also plan a nice holiday for the family. We go to interesting places and learn many new things. During our summer vacations we have visited the mountains of Himachal Pradesh, the desert areas in Rajasthan and the seaside in Tamil Nadu. When we go to different places in the country we eat the local food, and buy the local spices and other food items for use at home.
I like to take photographs of the beautiful landscape and the local people in the different places we visit. I have an interesting collection of photographs that I have taken in the many visits we have made during my vacations.
We also visit our grandparents who live in Nainital, in the hills of Uttarakhand. Visiting our grandparents is special because they dote on my brother and me, and pamper us a great deal.
I always look forward to my summer vacation as it is very enjoyable.
