Answer:
True.
Explanation:
DNA's replication is the process where each daughter cell receives the same copy of the DNA. During the synthesis phase of the cell cycle replication of DNA occurs. While increasing speed of replication the DNA molecule is opened at several locations, and creating multiple replication bubbles.
Replication bubbles opened DNA strands at several locations where DNA are complementary to each other, such as one strand of DNA contains a nucleotides sequence of TCAGTA will have a complementary another strand with the sequence AGTCAT.
Answer:
The correct answer is - the hippocampus.
Explanation:
Hippocampus is the part of the brain located deep in the temporal lobe that is related to memory and learning abilities. The hippocampus is present in humans and other mammals, two in numbers.
Injuries to the hippocampus will be lead to problems that are associated with a memory like recognition and identifying people or things or the ability to learn things. Direction, locations type of memories would be affected if damaged.
Answer:
Nitrogen is present in the atmosphere in a molecule form about 78 percent. This nitrogen comes to the earth with the water through rainfall. Some nitrogen fix by beneficial microorganisms such as Cyanobacteria and Azotobactor which are present in the roots of higher plants. These microorganisms convert nitrogen molecule into nitrates and used by the plants. There are some other microorganisms which again convert nitrate into nitrogen molecules, called denitrifying bacteria and nitrogen molecule goes to the atmosphere again and complete the cycle.
The meteorite was probably 1<span>0 to 15 km (6.2 to 9.3 mi) wide</span> and affected the entire planet through a proces called "impact winter". As the name suggests, an impact winter is a period of low temperature produced by a huge cloud of ash and dust that blocks sunlight. Since sunlight is essential for plants to survive, if the sun rays are blocked by this cloud, all animals that depend on those plants (including dinosaurs) will die. The meteorite could have created such a cloud upon hitting the earth.
Answer:
Photogenic means looking attractive in photographs or on film. Photography means a picture made using a camera, in which an image is focused onto film or other light-sensitive material and then made visible and permanent by chemical treatment, or stored digitally.
